[0001] BACKGROUND OF THE INVENTION The present invention relates to a motorized scooter. In particular, it finds an application for the practice of outdoor recreation or for medium or long-distance journeys, particularly in urban areas, for example in the context of intermodality. By intermodality, we understand the combination of different modes of transport, such as walking, cycling, scooter, metro, bus, ... used on a single course. Motorized scooters are known whose power of the motor 10 is controlled by a control member actuated by the user. Such a scooter is in particular proposed by the document US 2002/170 763, which describes a scooter comprising a frame, a front wheel and a rear wheel fixed to the frame, a motor configured to drive the rear wheel in rotation, and a control member. motor control. By actuating the control member, the user chooses one of the predetermined powers of the engine, and, consequently, the speed of the scooter. Motorized scooters are also known whose control member comprises a trigger disposed, for example, on the handlebar of the scooter. By actuating the trigger, for example by pivoting it around the axis of the handlebar, the user modifies the power of the engine, similarly to the actuation of the control member of a moped. Nevertheless, such products do not satisfy the users who wish to benefit from an assistance making it possible to reduce the muscular effort in order, for example, to travel longer distances than with a usual scooter, while retaining the possibility of practicing the scooter in the traditional way, that is to say, for example, by keeping one foot on the frame of the scooter, while the other foot applies impulses on the ground. In addition, such products do not allow to automatically adapt the power of the engine to the forces exerted by the user. OBJECT AND SUMMARY OF THE INVENTION The object of the present invention is to solve, among others, the deficiencies described above of existing motorized scooters by proposing a motorized scooter whose engine power is controlled. by the efforts exerted by the user. This object is achieved by the fact that the invention relates to a scooter whose control member comprises: acceleration detection means for detecting an acceleration phase of the scooter; deceleration detection means for detecting a deceleration phase of the scooter; the control member being configured to actuate the motor when a deceleration phase having a duration at least equal to a first predetermined threshold has been detected by the deceleration detection means after an acceleration phase has been detected by the acceleration detection means. Thus, this device is configured so that the motor is actuated according to the forces exerted by the user. By accelerating and decelerating the scooter, it includes a phase during which, respectively, the speed of the scooter increases and decreases. More particularly, the control member is configured to actuate the motor after a muscular effort has been exerted by the user.
[0002] By muscular effort, one understands, for example and without limitation, an impulse given by the user to the scooter to put or maintain the scooter in motion, the user applying, by one of his legs, a pressure on the ground, while the other leg is held on the frame of the scooter, and more particularly on the platform disposed between the front and rear wheels. Conditioning the actuation of the motor to a detection of a deceleration phase following the detection of an acceleration phase makes it possible not to actuate the motor if the user exerts a pulse on the scooter, which would risk, among other things, to disrupt the traditional and manual use of the scooter by the user. The controller can thus be disabled so that the motorized scooter according to the present invention does not eliminate the possibility for the user to put or keep the scooter in motion by means of the traditional muscular efforts. Furthermore, the fact of conditioning the actuation of the motor to a detection of a sufficiently long deceleration phase makes it possible not to actuate the motor when the user exerts a new pulse, substantially immediately after the acceleration detected by the acceleration detection means. In other words, the control member is configured so that when the user exerts different consecutive pulses closely, for example to initiate the movement of the scooter after its immobilization, the motor is not actuated , so as not to disturb the efforts exerted by the user. Successive successive pulses include pulses which are exerted by the user without a duration greater than the first predetermined threshold elapsing between the end of the acceleration phase detected by the acceleration detection means. the outcome of a first pulse, and the beginning of the acceleration phase, also detected by the acceleration detection means, at the end of the next pulse. In other words, two successive pulses must take place in a time less than the first predetermined threshold. At the end of the acceleration phase, we understand the moment preceding the moment when the speed of the scooter begins to decrease, for example because of the friction of the scooter on the road on which it evolves. When the user no longer exerts a new impulse on the scooter, the scooter describes a deceleration phase detected by the deceleration detection means; when the deceleration detection means detects a deceleration phase whose duration is greater than the first predetermined threshold, the motor is actuated so as to suppress the deceleration of the scooter. In other words, the motor control member is configured to actuate the motor so as to supplement the muscle forces exerted by the user. The invention is set forth below in a series of alternative embodiments, which may be considered alone or in combination with one or more of the previous ones. Advantageously, the control member is configured to actuate the motor after detecting said deceleration phase so that the speed of the scooter is maintained at a set speed. By this arrangement, the control member is configured so that the motor is operated to suppress the natural deceleration of the scooter inherent, for example, to frictional forces. Advantageously, the target speed is a function of the triggering speed. Trigger speed is understood to mean the speed of the scooter when the motor is actuated. The trip speed may therefore correspond to the speed of the scooter at the end of the duration of the deceleration phase detected by the deceleration means; alternatively, it may correspond to a speed lower than the speed of the scooter at the end of the duration of the deceleration phase detected by the deceleration means, in the event that the engine is not actuated simultaneously with the end of the duration of the deceleration phase detected, but slightly later, the speed of the scooter continuing, in this case, to decrease. Thus, the control member is configured in such a way that the assistance of the scooter is a function of the forces exerted by the user which made it possible to reach the triggering speed. It is thus understood that the control member is configured so that the assistance generated by the actuation of the motor is exerted so as not to surprise the user, by a motor power which would be independent of the speed of the motor. scooter detected at the end of the deceleration phase detected by the deceleration detection means whose duration exceeds the first predetermined threshold. Preferably, the target speed is equal to the speed of the scooter when the engine is actuated. By this arrangement, the assistance generated by the actuation of the motor is particularly fluid, and causes no acceleration or sudden and abrupt deceleration, likely to surprise the user, or even destabilize. Advantageously, the control member is configured to determine a speed at the end of said deceleration phase, and to actuate the motor after detection of said deceleration phase so that the speed of the scooter is greater than the speed determined at the end. of said deceleration phase. By this arrangement, the assistance provided by the actuation of the motor makes it possible to reduce or even eliminate the effects of the deceleration during the time substantially equal to the first predetermined threshold of the deceleration phase detected by the deceleration detection means. . In other words, the control member is configured to actuate the motor so that the speed of the motorized scooter approaches the target speed that the user wants to make the scooter take, at the end of the / impulses (s) he has exercised (s). Advantageously, the controller is configured to operate the motor for a predetermined period of time. By this arrangement, the motor is not actuated continuously, thereby alternating the manual propulsion phases, for example by means of pulses exerted in the traditional manner by the user, and assisted propulsion phases, by the actuation of the motor. In addition, by this provision, the assistance capacity of the scooter, which combines different modes of propulsion, is increased. Preferably, the controller is configured to stop motor operation when a new acceleration phase is detected while the motor is actuated. By this arrangement, the traditional use of the scooter, by means of pulses exerted by the user, is not prevented by the actuation of the engine. Advantageously, the control member is configured to actuate the motor again when a new deceleration phase having a duration at least equal to the first predetermined threshold has been detected by the deceleration detection means after the new phase of acceleration. Thus, the phases of assistance by the actuation of the motor and manual propulsion by the pulses exerted by the user can 5 chaining in a fluid and intuitive way, thus allowing to combine the advantages of a motorized assistance to the sporting practice inherent in scooter riding. The user can therefore decide to increase the set speed by giving a new impulse. Advantageously, the scooter further comprises a scooter speed determining device, and the controller is configured to stop engine operation when a positive variation in scooter speed greater than one second predetermined threshold is detected. Thus, when the speed of the scooter exceeds the scooter's target speed by more than the second predetermined threshold, or, in other words, when the speed of the scooter increases by more than the second predetermined threshold with respect to the speed of the scooter. set point, the actuation of the motor is interrupted. By this arrangement, the safety of the user as well as that of persons moving near the scooter are not compromised by the device according to the present invention, the motorized assistance not being added to the effects of this increase of the speed which may be due, for example and without limitation, to a downward slope of the road on which the scooter is moved, to a new impetus exerted by the user. . . Preferably, the control member is configured to stop the actuation of the motor when the positive variation of the speed of the scooter is greater than the second predetermined threshold for a duration greater than a third predetermined threshold. By this arrangement, the actuation of the motor is not stopped by an acceleration greater than the second predetermined threshold for a duration less than the third predetermined threshold. In other words, the assistance of the scooter is not stopped by a sudden but brief acceleration, such accidental acceleration being able to occur, for example, due to roughness of the road or contact with the road. the edge of a sidewalk. By accidental acceleration, it is understood any distinct acceleration of an acceleration caused voluntarily by an impulse given by the user to the scooter. Advantageously, the control member is configured so as not to actuate the motor when the speed of the scooter is greater than a fourth predetermined threshold. In other words, the maximum speed achievable by the engine is less than the fourth predetermined threshold. By this arrangement, the scooter can not be maintained, by the actuation of the engine, at a speed greater than the fourth predetermined threshold, so as not to compromise the safety of the user and other users of space on which the scooter evolves. This arrangement makes it possible in particular to comply with the intended uses on the public space, for example when the scooter 15 moves on a sidewalk. Advantageously, the control member is configured so as not to actuate the motor when the speed of the scooter is less than a fifth predetermined threshold. By this arrangement, the motor is not actuated inadvertently, for example when the user walks beside the scooter. Preferably, the scooter further comprises a braking device, and the control member is configured to stop the actuation of the engine when the braking device is actuated. Thus, in a simple and intuitive manner, the actuation of the engine is stopped, to allow the user to reduce effectively and quickly the speed of the scooter and thus to adapt to the constraints encountered. BRIEF DESCRIPTION OF THE DRAWINGS Other features and advantages of the invention will appear more clearly and completely on reading the description hereafter of a preferred embodiment given by way of non-limiting example and with reference in the following accompanying drawings in which: - Figures 1A and 1B schematically show an example of a scooter according to the present invention; and FIGS. 2A, 2B and 2C schematically show various examples of temporal changes in the speed of the scooter according to the present invention. DETAILED DESCRIPTION OF THE INVENTION In the example shown in FIGS. 1A and 1B, the scooter 10 according to the invention comprises, in the traditional way, a frame 12, a front wheel 20 and a rear wheel 22. The frame 12 of the scooter 10 comprises a platform 14 arranged between the front and rear wheels 22, and a steering column 16, one end of which is fixed to the front wheel 20, the steering column 16 having a handlebar 18 to its front. opposite end. In addition, the scooter 10 according to the present invention comprises a motor 24 configured to rotate the front wheel 20 and a control member 26 configured to control the motor 24. For example, and without limitation, the motor 24 of the scooter 10 is an electric motor mounted on the hub of the front wheel 20, the scooter 10 further comprising a battery 28 disposed between the steering column 16 and the platform 14 . Of course, without departing from the scope of the present invention, it is conceivable to design any other type of engine, such as a combustion engine, configured to rotate one or the other of the front and rear wheels 22 . The scooter 10 further comprises a braking device 30, 25 which can be actuated, for example and without limitation, from the handlebar 18 of the scooter 10, the braking device being configured to oppose the rotation of the scooter. front wheel 20. The scooter 10 also comprises a device for determining the speed of the scooter; for example and without limitation, the speed determining device is a sensor 11 mounted on the rear wheel 22 and configured to acquire, at regular intervals separated by a period t0, the speed of the scooter 10. It can also be a speed sensor rotation of one of the two wheels of the scooter. Furthermore, the control member 26 comprises, in particular, acceleration detection means 26a and deceleration detection means 26b, configured to detect an acceleration phase and a deceleration phase, respectively. scooter 10. The control member 26 is configured to actuate the motor 24, and thereby rotate the front wheel 20 of the scooter 10, if certain conditions, which will become more apparent in the description of FIGS. 2A, 2B and 2C, are fulfilled. . FIGS. 2A, 2B and 2C show diagrammatically examples of temporal changes in the speed of the scooter 10 according to the present invention. More particularly, FIGS. 2A, 2B and 2C show the changes in the speed of the scooter 10, as a function of the actions exerted by the user of the scooter 10, these actions being able to consist of pulses 10, 11, 12, 13 , i4, i5 applied by the user on the scooter 10, or an actuation fi of the braking device 30. FIGS. 2A, 2B and 2C show first, second, second, third, third, fourth, fourth and fifth predetermined thresholds which will be described in more detail below. In this nonlimiting example, the first predetermined threshold if has a value of 200 ms; the second predetermined threshold s2 has a value of 10 revolutions per minute; the third predetermined threshold s3 has a value of 200 ms; the fourth predetermined threshold s4 has a value of 400 revolutions per minute; the fifth predetermined threshold s5 has a value of 100 revolutions per minute. Moreover, FIGS. 2A, 2B and 2C alternately show in dashed lines and in full lines the phases during which the scooter operates respectively manually, thanks to the muscular efforts exerted by the user, and with the assistance of the motor 24 actuated by the control member 26. For the sake of clarity, the lower part of FIG. 2A represents the periods during which the motor 24 is actuated by the control member 26, the height of the various blocks being a function of the speed at which the scooter 10 is maintained. during the different phases of actuation of the motor 24. Traditionally, the scooter 10 is initially stopped, in order to set it in motion, the user exerts a first pulse iO. As shown in FIG. 2A, the velocity measurements periodically made by the sensor 11 every 10 ms, with t 0 being, for example and in a non-limiting manner, 40 ms, are increasing; the acceleration sensing means 26a thus detect an acceleration phase. The speed reached by the scooter 10 at the end of this first pulse iO is less than the fifth predetermined threshold s5. The controller 26 is configured to not operate the motor 24 when the speed of the scooter 10 determined by the speed determining device is less than the fifth predetermined threshold s5; the motor 24 is not actuated at the end of this first pulse iO. After detection by the acceleration sensing means 26a of the control member 26 of the acceleration phase caused by the first pulse 10, the deceleration detecting means 26b detects a deceleration phase for a period of less than first predetermined threshold if. The controller 26 is configured to actuate the motor 24 when a deceleration phase having a duration greater than or equal to the first predetermined threshold if has been detected by the deceleration detection means after a phase of deceleration. acceleration was detected by the acceleration detection means; the motor 24 is not actuated during this deceleration phase. The user then exerts a new impetus. As shown in FIG. 2A, following this pulse 11, the acceleration detection means detect an acceleration of the scooter, during which its speed, determined by the speed determining device, exceeds fifth predetermined threshold s5, until reaching the speed vm1, shown in Figure 2B. For example, and in a nonlimiting manner, the acceleration detection means detect an acceleration phase of the scooter 10 when the speeds determined successively by the device for determining the speed, measured at a regular interval t 0, are increasing. The deceleration detection means detect, for their part, a deceleration phase of the scooter 10 when the speeds determined successively by the device for determining the speed, measured at a regular interval t 0, are decreasing. In particular, between times P1 to P6 shown in Fig. 2B, the speed of the scooter 10 determined by the speed determining device is decreasing. Of course, any other means of detecting acceleration and deceleration could be conceived without departing from the scope of the present invention. As shown in FIG. 2B, in which a deceleration phase follows an acceleration phase respectively detected by the deceleration detection means and the acceleration detection means, when the deceleration phase detected by the means of deceleration detection has a duration greater than the first predetermined threshold if, the control member 26 actuates the motor 24. In the nonlimiting example shown in FIG. 2B, the speed vmi represents the greatest value of the speed of the scooter 10 determined by the speed determination device, reached at the moment P1; the moment P1 corresponding to the measurement of the speed vmi 20 thus corresponds to both the end of the acceleration phase detected by the acceleration detection means, and at the beginning of the deceleration phase detected by the means of deceleration detection. As shown in FIG. 2B, the first predetermined threshold si has a value, for example and in a nonlimiting manner, of intervals t0, during which the speeds are determined by the device for determining the speed at times P2, P3, P4, P5 and P6; at the end of the fifth decreasing speed determined as a result of the speed vmi by the speed determining device at the instant P6, the motor 24 is actuated by the control member 26. The instant P7 shown in FIG. 2B thus corresponds to the first speed determined by the speed determination device during the actuation of the motor 24. In the example shown, where 5 intervals of a duration of t0 = 40 ms are considered during the deceleration phase detected by the deceleration detection means 26b, the first predetermined threshold so has a value of 200 ms. In other words, it will be understood that the control member 26 of the motor 24 detects, by means of its acceleration detection means, an acceleration phase of the scooter 10, followed by a decelerating phase of the scooter 10, detected by its deceleration detection means. When the deceleration phase detected by the deceleration detection means has a duration at least equal to the first predetermined threshold if the control member 26 actuates the motor 24. As shown particularly in FIG. 2A, the control member 26 is configured to actuate the motor 24 so that the speed of the scooter 10 is maintained at a set speed vi, at the end of the pulse he. As represented in FIG. 2B, the set speed vi is a function of the speed of the scooter 10 when the motor 24 is actuated. In this example, the set speed vi has a constant value of about 180 rpm. As will become more clearly apparent in the rest of the description, the set speed vi, at which the scooter 10 is maintained at the end of the pulse 11, is greater than the speed vdi determined by the device for determining the speed. speed at the end of the duration if the deceleration phase detected by the deceleration detection means. For example and without limitation, the control member 26 applies a factor greater than 1 to the speed vdi, for example 1. 05. Of course, without departing from the scope of the present invention, it would be possible to design a control member 26 configured to actuate the motor 24 so that the set speed vi is equal to the speed vdi determined at the end of the duration. if the deceleration phase detected by the deceleration detection means. Alternatively, without departing from the scope of the present invention, the control member 26 could be configured to actuate the motor 24 so that the reference speed vi is equal to one of the speeds determined by the device for determining the speed. speed during the deceleration phase, prior to the instant when the speed vdi is reached. As shown in FIG. 2A, the control member 26 is configured to actuate the motor 24 for a predetermined time T, for example equal to 60 seconds. As shown in FIG. 2A, during the period T 5 during which the motor 24 is actuated, slight variations in the speed of the scooter 10 may be determined by the speed determining device; the control member 26 is configured such that, when these variations are not significant, the actuation of the motor 24 is not interrupted. The sense of the significance of the scooter speed variations determined by the speed determining device when the motor 24 is actuated will become clearer in the following description. At the end of the predetermined duration T, the control member 26 interrupts the actuation of the motor 24, thus causing a deceleration of the speed of the scooter 10, related to the friction forces applied to the scooter 10. As shown in FIG. 2A, the user then applies a new pulse i2; the acceleration detection means thus detect a new acceleration phase. As shown in FIG. 2A, and similarly to the configuration described in the observation of FIG. 2B, the control member 26 of the motor 24 actuates the motor 24 when a deceleration phase of a greater duration or equal to the first predetermined threshold if has been detected by the deceleration detection means after an acceleration phase has been detected by the acceleration detection means. The control member 26 thus actuates the motor 24, so that the speed of the scooter 10 is maintained at a set speed 30 v2, in this example greater than vi, for example equal to 200 revolutions per minute. In particular, it can be seen that the reference speeds vi and v2, at which the speed of the scooter 10 is maintained respectively after the pulses 11 and 12, are different, insofar as they are a function of the speed of the scooter 10. moment of actuation of the motor 24 by the actuating member 26. 3 0 1 4 8 2 8 14 As shown in Figure 2A, a new pulse i3 is exerted by the user, while the motor 24 is actuated during the period T. As shown in particular in FIG. 2C, as a result of this user pulse 13, the acceleration detection means detect a new acceleration phase, during which the speed of the scooter 10 increases, substantially exceeding the set speed v2. More specifically, the positive variation of the speed of the scooter, considered from the set speed v2, is greater than the second predetermined threshold s2. As it appears from the observation of FIG. 2C, the control member 26 is configured so that, when the speed of the scooter 10 determined by the speed determining device exceeds the set speed v2 by more than second predetermined threshold 15 s2 for a duration greater than the third predetermined threshold s3, the actuation of the motor 24 is interrupted. In other words, the controller has detected a new pulse from the user and stops the motor operation. At the end of the acceleration phase detected by the acceleration detection means caused by the pulse i3, and in a manner similar to the behavior represented in FIG. 2A at the end of pulses 11 and 12, the means deceleration detection detects a deceleration phase whose duration exceeds the first predetermined threshold if, so that the actuating member 26 actuates the motor 24, allowing to maintain the speed of the scooter 10 at a set speed v3 , definitely greater than v2. In this example, v3 has a value of about 360 rpm. The user exerts a new pulse i4, during the actuation of the motor 24, during the period T. Similar to the behavior of the scooter 10 described with reference to FIG. 2C, the control member 26 interrupts the actuation of the motor 24 when the positive variation of the speed of the scooter 10, with respect to the set speed v3, is greater than the second predetermined threshold s2 for a duration greater than the third predetermined threshold s3. As shown in FIG. 2A, at the end of the acceleration phase detected by the acceleration detection means and caused by the pulse i4, the speed of the scooter 10 determined by the speed determining device is greater than the fourth threshold s4, which in this example is equal to 400 rpm. As a safety measure, the control member 26 is configured not to actuate the motor 24 when the speed of the scooter 10 determined by the determining device is greater than the fourth threshold s4. As a result, the motor 24 is not actuated; the deceleration detection means then detect a deceleration phase during which the speed of the scooter 10 decreases, until the user exerts a new pulse i5, as shown in Figure 2A. In a manner similar to the behavior described above, a deceleration phase of a duration greater than the first predetermined threshold if being detected by the deceleration detection means after an acceleration phase has been detected by the detection means of acceleration, at the end of the pulse i5, the control member 26 actuates the motor 24. The motor 24 is then actuated by the control member 26 so that the speed of the scooter 10 is maintained at a set speed v5 at the end of the pulse i5, the set speed v5 being similarly to the other actuation phases of the motor 24 described above, a function of the speed of the scooter 10 determined by the speed determining device when the motor 24 is actuated. In this nonlimiting example, the target speed v5 is slightly greater than the speed determined at the end of the deceleration phase; it is for example 330 revolutions per minute. As shown in FIG. 2A, during the operation of the motor 24 by which the speed of the scooter 10 is maintained at the set speed v5, a short positive variation of the speed of the scooter 10 is determined by the speed determination device; unlike the behavior described with reference to FIG. 2C, the positive variation of the speed of the scooter 10 is not greater than the second predetermined threshold s2 for a duration greater than the third predetermined threshold s3. As previously described, the control member 26 being configured to stop the actuation of the motor 24 when the positive variation of the speed of the scooter 10 is greater than the second predetermined threshold s2 for a duration greater than a third threshold predetermined s3, the actuation of the motor 24 is not stopped by the control member 26 when the speed determining device detects said short positive variation of the speed of the scooter 10. In other words, the variation of the speed of the scooter 10 shown in FIG. 2A during the actuation of the motor 24 following the impulse 15 is accidental in nature, and not caused by a new impulse exerted by the user, the control member 26 does not interrupt the actuation of the motor 24. So that a variation in the speed of the scooter 10 determined by the speed determination device is considered significant by the control member 26 and that it causes, as such, the interruption of the actuation of the motor 24, it is therefore necessary, on the one hand, that it be greater than the corresponding reference speed by a value at least equal to the second predetermined threshold s2, and that, on the other hand, the exceeding of the second threshold predetermined s2 is determined by the device for determining the speed for a duration greater than the third predetermined threshold s3. After this accidental acceleration, and as represented by the reference f1 in FIG. 2A, the braking device 30 is actuated by the user. The controller 26 is configured to stop the actuation of the motor 24 when the braking device 30 is actuated by the user. As a result, the deceleration detection means detect a new deceleration phase during which the speed of the scooter 10 decreases to be less than the fifth predetermined threshold s5. The controller 26 of the scooter 10 according to the present invention may also include a parameter setting device configured to allow the user to modify the value of the predetermined thresholds s1, s2, s3, s4. and s5. The duration of the period t0 for determining the speeds of the scooter 10 by the speed determining device can also, without departing from the scope of the present invention, be modified by the parameter setting device. One could also design a controller 26 configured to operate the motor 24, when the conditions described above are met, unlimitedly. As described with reference to FIGS. 1, 2A, 2B and 2C, the scooter 10 according to the present invention is thus configured to implement a motorized assistance method comprising: a step of detecting an acceleration phase; scooters; A step of detecting a deceleration phase of the scooter; a step of measuring the duration of the deceleration phase; and a step of actuating the motor 24 when the deceleration phase has a duration at least equal to the first predetermined threshold s1. The motor assistance method also includes a step of detecting a new acceleration phase during the motor operation step, and a step of stopping the motor operation. Furthermore, the motorized assistance method implemented by the scooter 10 according to the present invention also comprises: a step of detecting a positive variation of the speed of the scooter higher than the second predetermined threshold s2 during the actuation of the engine; a step of measuring the period during which the positive variation of the speed of the scooter is greater than the second predetermined threshold s2; and a step of stopping the actuation of the motor 24 when the positive variation of the speed of the scooter is greater than the second predetermined threshold s2 for a duration greater than the third predetermined threshold s3. Finally, the motor assistance method also comprises a step of detecting a possible actuation of the braking device 30 while the motor is actuated, and a step of stopping the actuation of the motor, in case of detection of the actuation of the braking device. The above description is given by way of example, and is therefore not limiting of the invention.
[0003] In particular, the invention, although particularly suited to the field of scooters, can also equip any means of displacement, such as a bicycle or a skateboard, so as to provide a motorized assistance without preventing the traditional operation of the means of displacement.
