The invention will be better understood on reading the description which follows, given solely by way of example and with reference to the appended figures in which: FIG. 1 schematically represents a device for assisting driving according to a exemplary embodiment of the invention; FIGS. 2 to 5 represent driving instruction pictograms, respectively in four different situations, displayed by display means of the driving assistance device of FIG. 1; and FIGS. 6 to 11 represent driving instruction pictograms according to an embodiment variant, respectively in six different situations, displayed by display means of the device of FIG. 1.
    There is shown in Figure 1, a device 10 for driving assistance, intended to equip a railway vehicle.
    As a rail vehicle is intended to run on a railway, it follows a predefined path, so that it is possible to provide an optimal speed of movement of the railway vehicle, in particular in order to minimize the energy consumption of the vehicle, while taking into account the schedules that must respect this vehicle.
    More particularly, the railway can be cut into a plurality of track sections, an optimum speed can be defined on each section. Indeed, the optimum speed is usually different depending on the section on which the rail vehicle is located, particularly depending on whether the section is in a straight line or curve, downhill or uphill, and so on. The length of a section of lane is chosen during the configuration of the driver assistance device 10, and can be any. It is also possible to provide various sections of track of different lengths.
    Thus, the driver assistance device 10 according to the invention comprises means 12 for determining a target speed Vc, for example corresponding to an optimum speed for limiting the energy consumption of the railway vehicle.
    As indicated above, the optimum speed depends on the section of track on which the railway vehicle is located, so that it is necessary to be able to determine on which section of track the rail vehicle is located. For this purpose, the driving assistance device 10 advantageously comprises locating means 14, for example a satellite guide device.
    The determination means 12 may be of any type that can be envisaged.
    According to a first example, these determination means 12 are formed by a memory in which is stored, for each section of track, a target speed Vc (including a predetermined optimum speed) corresponding to this section of track. Thus, at any time, the locating means 14 make it possible to determine on which section of track the rail vehicle is located, and the determining means 12 deduce therefrom the target speed Vc.
    Each predetermined target speed Vc is calculated beforehand, taking into account the energy consumption of the railway vehicle and the schedules to be respected by this rail vehicle. Other characteristics may be taken into account for determining the target speed Vc, in particular the characteristics of the vehicle (such as its number of cars and its length), the characteristics of the section of track considered (in particular if it comprises at least a rise and / or at least a descent, if it is in a straight line and if it includes curves, in which case the radii of curvature of these curves can also be taken into account) and environmental conditions (for example the season ).
    According to a second example, the determination means 12 comprise means for calculating in real time the target speed Vc, comprising a calculation algorithm determining the target speed Vc according to the characteristics mentioned above. Such real-time calculation means may also take into account a possible delay or an advance on the schedules that the rail vehicle must respect.
    According to a third example, the determining means 12 comprise learning means. In this case, when the railway vehicle travels along the railway, the learning means record at each trip the speed of the railway vehicle on each section of track considered. Then, during the subsequent paths, the learning means choose, on each section of track, the speed that seems most suitable among those recorded on this section, this most suitable speed then forming the target speed Vc.
    The driving assistance device 10 also comprises conventional traction level control means 16, generally formed by a traction / brake control lever. This control lever 16 is actuated by the driver of the railway vehicle, to apply to the railway vehicle a level of traction or braking to change the instantaneous speed V ,, desired by the driver, in order to approach the speed target Vc.
    The driving assistance device also comprises means 18 for determining a maximum speed Vmax, as a function of the section of track on which the rail vehicle is located.
    These means 18 for determining maximum speed Vmax are linked to locating means 14 indicating on which section of track the rail vehicle is located, so that the means 18 for determining maximum speed can deduce what is the maximum speed Vmax allowed for the vehicle. rail.
    The means 18 for determining maximum speed comprise, for example, a database in which a respective predetermined maximum speed Vmax is indicated for each section of track.
    Alternatively, the maximum speed Vmax could be provided in real time by a centralized control center, or by terminals arranged along the railway.
    The driver assistance device 10 also comprises means 20 for comparing the instantaneous speed V, of the railway vehicle, depending on the control means 16, with the target speed Vc indicated by the determination means 12. Advantageously, a The target velocity interval is defined around the target velocity Vc, and the comparison means 20 compares the instantaneous velocity V with this target velocity interval. This interval is delimited by a first speed lower than the target speed Vc and a second speed higher than the target speed Vc.
    The first and second speeds are therefore predetermined as a function of the target speed Vc. Thus, these first and second speeds are determined dynamically, subtracting, respectively adding, a predefined value to the target speed Vc, or alternatively applying a percentage to this target speed Vc.
    In a variant, the first and second speeds are identical, equal to the target speed Vc.
    Advantageously, these comparison means 20 also compare the instantaneous speed V with the maximum speed Vmax entered by the determination means 18.
    These comparison means 20 provide the results of the comparisons to progressive means of indicating driving instructions to the driver of the railway vehicle.
    These driving instructions notably comprise instructions for modifying the instantaneous speed V, in order to approach the target speed Vc, in particular an instruction for increasing the speed when the instantaneous speed V is less than the target speed Vc. , a speed reduction instruction when the instantaneous speed V, is greater than the target speed Vc, and a speed maintaining instruction when the instantaneous speed V, is substantially equal to the target speed Vc.
    The speed increase and decrease instructions each comprise at least one variable value indicator according to the difference between the instantaneous speed V and the target speed Vc
    The progressive means of indication 22 may comprise various possible display devices.
    For example, the progressive indication means 22 comprise a display panel 24, in particular a display screen, capable of displaying driving instructions, in the form of driving instruction pictograms.
    Alternatively or in a complementary manner, the indication means 22 comprise a head-up display device 34, able to display the driving instructions in a field of view of the driver. Such a head-up display device 34 is known per se and will therefore not be described in more detail.
    In these cases, the progressive indication means 22 are configured to: display a speed increase instruction pictogram when the instantaneous speed V is below the target speed interval Vc, that is, ie below the first predetermined speed, - display a speed reduction instruction pictogram when the instantaneous speed V, is above the target speed interval Vc, i.e. above the second predetermined speed, and - display a speed keeping instruction pictogram when the instantaneous speed V, is in the target speed interval Vc.
    On the other hand, when the instantaneous speed V is greater than the maximum speed Vmax, the indicating means 22 indicate an imperative instruction for reducing the speed.
    Advantageously, the indication means 22 also indicate the values of the instantaneous speed V ,, of the target speed Vc, and of the maximum speed Vmax.
    Each driving instruction pictogram comprises a variable value indicator, in particular an element of variable size, for example a speed gauge 25, as represented in FIGS. 2 to 5.
    Alternatively, as shown in FIGS. 6 to 11, each instruction pictogram comprises an arrow of variable size according to the instructions for modifying the instantaneous speed V, in order to approach the target speed Vc.
    The instruction pictograms displayed by the head-up display device 34 are for example identical to those displayed by the display panel 24, and comprise a speed gauge 25 as represented in FIGS. 2 to 5, and / or arrows as shown in Figures 6 to 11.
    FIGS. 2 to 5 show the speed gauge 25 displayed by the indication means 22, in particular by the display panel 24 and / or the head-up display device 34, in different respective situations. This speed gauge 25 comprises a first line representing the instantaneous speed V ,, and a second line representing the target speed Vc. In this case, the variable value indicator is the distance between the first and the second line.
    In FIG. 2, the instantaneous speed V is less than the target speed interval Vc, so that the indication means 22 display a speed increase instruction pictogram comprising an arrow 26 directed towards the high.
    As a variant, or in a complementary manner, the speed gauge 25 is displayed with a first color, for example in yellow, when the instantaneous speed V is less than the target speed interval Vc. Thus, the driver is urged to act on the control means 16 so as to modify the level of traction in order to comply with the instruction to increase the speed.
    FIG. 3 shows the speed gauge 25 when the instantaneous speed V is in the target speed interval Vc. In this case, the indication means 22 display a speed keeping instruction pictogram. This speed maintenance instruction pictogram comprises for example an "equal" symbol 28.
    Alternatively, the instruction pictogram may comprise only the speed gauge 25, the speed keeping indication being then materialized by a lack of speed modification instruction. In the same way as above, a color code may be provided to indicate the speed keeping instruction, by displaying the speed gauge 25 with a second color different from the first, for example in green, when the instantaneous speed V , is in the target velocity interval Vc.
    FIG. 4 shows the speed gauge 25 when the instantaneous speed V is greater than the target speed interval Vc. In this case, the indication means 22 display a speed reduction instruction pictogram, for example comprising a descending arrow 30. As a variant or in a complementary manner, the color of the speed gauge 25 can be modified, and takes a third color, distinct from the second color, and distinct from the first color, for example orange, to indicate that the instantaneous speed V, is greater than the target speed interval Vc. Alternatively, the third color is identical to the first color.
    FIG. 5 shows the speed gauge when the instantaneous speed V is greater than the maximum speed Vmax. In this case, the indication means 22 display an imperative speed reduction instruction pictogram, for example having a double descending arrow 32, or alternatively a descending arrow identical to the descending arrow 30. Alternatively or in a complementary manner , the speed gauge may take a fourth color, distinct from the first, second and third colors, for example red, to indicate that the instantaneous speed V, is greater than the maximum speed Vmax.
    Figures 6 to 11 show instruction pictograms displayed by the indicating means 22, in particular by the display panel 24 and / or the head-up display device 34, in different respective situations.
    In this case, the variable value indicator is formed by the arrow displayed, whose height is variable according to the difference between the instantaneous speed V, and the target speed Vc.
    In FIG. 6, the instantaneous speed V is smaller and further away from the target speed interval Vc, so that the indicating means 22 display a speed increase instruction pictogram with an arrow 40 of large size, facing upwards. The arrow 40 preferably has a first color, for example yellow. Thus, the driver is urged to act on the control means 16 so as to modify the level of traction in order to comply with the instruction to increase the speed.
    As shown in FIG. 7, when the instantaneous speed V, approaches the target speed Vc, while remaining below this target speed Vc, the indication means 22 display an instruction icon for increasing the speed. speed, having an arrow 42 of medium size, directed upwards, for example yellow. The driver is thus invited to continue the acceleration.
    As shown in FIG. 8, when the instantaneous speed V, is close to the target speed interval Vc, while remaining below this target speed Vc, the indication means 22 display an instruction pictogram of increasing the speed, comprising a small arrow 44, directed upwards, for example yellow. The driver is thus invited to reduce the tensile stress.
    As shown in FIG. 9, when the instantaneous speed V is in the target velocity interval Vc, the indicating means 22 display a speed keeping instruction pictogram having an image 46 symbolizing the maintaining speed, for example an "equal" symbol or a message, especially "ECO" indicating that it has reached an economic speed. In the same way as above, it is possible to provide a color code to indicate the speed-keeping instruction, by displaying this instruction pictogram with a second color different from the first, for example in green.
    As shown in FIG. 10, when the instantaneous speed V is slightly greater than the target speed interval Vc, the indication means 22 display a speed reduction instruction pictogram, for example having an arrow The driver is thus prompted to reduce the instantaneous speed V ,.
    Alternatively or in a complementary manner, the arrow color 48 may be modified, and takes a third color, distinct from the second color, and distinct from the first color, for example orange, to indicate that the instantaneous speed V, is greater than the target speed interval Vc. Alternatively, the third color is identical to the first color.
    If the instantaneous speed V, still increases, the indication means 22 display a speed reduction instruction pictogram, for example having a down arrow of average size 50, as shown in FIG. 11. The driver is thus prompted to reduce the instantaneous velocity V ,.
    The downward arrow 50 may have another color, for example red, when the instantaneous speed V, is greater than the maximum speed Vmax.
    It will be noted that the size of the ascending arrow 40, 42, 44 or descending 48, 50 depends on the difference between the instantaneous speed V, and the target speed Vc. This allows the driver to know if he is getting closer to the target speed Vc.
    Alternatively, or in a complementary manner, the indication means 22 comprise haptic means 36 acting on the lever 16 for controlling the traction / braking of the railway vehicle. Such haptic means 36 (or tactile-kinesthetic) are intended to modify the haptic feeling of the driver when he actuates the control lever 16.
    The haptic means 36 may also be used to actuate the control lever to return it to a neutral position as a spring would do. For example, the haptic means 36 are formed by a motor that interacts with the axis of the control lever. This engine is for example type contactless or brushless ("brushless" in English). This characteristic makes it possible to meet the needs of several modes of driving rolling stock: tram, metro, regional train, high-speed train, locomotive.
    When the instantaneous speed V is less than the target speed Vc, the resistance forces transmitted by the haptic means 36 correspond to a predetermined first resistance range, in which the resistance forces are then reduced to correspond to the equivalent forces of a classic manipulator.
    When the instantaneous speed V is greater than the target speed VCi, the resistance forces transmitted by the haptic means 36 correspond to a second predetermined range of resistances, in which the resistance forces are greater than those of the first range. resistance being thus increased to pass from the first range to the second range, and then maintained at a greater resistance effort than the equivalent efforts of a conventional manipulator. By feeling this change in resistance, the driver is encouraged not to exceed the recommended level of traction.
    In this case, the variable value indicator is the resistance force transmitted by the haptic means, this effort decreasing as the instantaneous speed V approaches the target speed Vc when the instantaneous speed V is less than the target speed Vc, and increasing as the instantaneous speed V, moves away from the target speed Vc when the instantaneous speed V, is greater than the target speed Vc.
    The driving assistance device 10 makes it possible to carry out a driving assistance method, comprising the following steps: a step of determining a target speed Vc (by the determination means 12), a step of comparing an instantaneous speed V, of the railway vehicle with the target speed Vc (by the comparison means 20), and a display step (by the display means 22) of a driving instruction pictogram to a driver of the railway vehicle, said driving instructions comprising instructions for modifying the instantaneous speed V, with a view to approaching the target speed Vc, so that: • when the instantaneous speed V, is lower at a first predefined value, an instruction for increasing the speed is indicated, • when the instantaneous speed V, is greater than a second predetermined value, a reduction instruction of the vi is indicated, and • when the instantaneous speed V, lies between the first and the second speed, a command to maintain the speed is indicated.
    Note that the invention is not limited to the embodiment described above, but could have various variants.
    In particular, the target speed could be determined with criteria other than the optimum speed mentioned above. For example, the target speed could take into account only the schedules to be respected, or only the energy consumption.
