    Title Method and control device for setting a control signal for controlling at least one safety device to a vehicle Prior art The invention is based on a control device or a method according to the preamble of the independent claims. The subject of the present invention is also a computer program.
    Generally, in a motor vehicle, at least one passenger protection device and at least one restraining means, which may be referred to herein as, for example, safety devices, may be built in to protect persons present in the vehicle in the event of an accident.
    DE 10 2011 084 204 A1 describes a method for controlling the safety control system of a motor vehicle.
    Description of the invention With this background, the method presented here presents a method, furthermore a control device, which is used by this method, and finally a corresponding computer program according to the main claims. Due to the measures stated in the dependent claims, advantageous further developments and improvements of the device specified in the independent claim are possible.
    According to embodiments, in particular, an adapted setting of a positioning of a single driver before a triggering of safety devices and before a collision or a collision with the vehicle can be carried out depending on a driving position [driving mode]. The driving mode can, for example, be set to manual or at least partially automatic driving. In other words, for example, a bimodal setting of pre-crash parameters and pre-crash parameters for a vehicle can be performed depending on a driving position. In particular, when the driver is driving manually, only limited safety measures can be taken, in order to be able to maintain a driving task as far as possible. In the case of at least partially automatic driving, for example, larger belt forces, seat length adjustments and the like can be applied, as the driving task is usually not affected.
    Advantageously, in accordance with embodiments, in particular a pre-collision use of effective safety systems and so-called pre-crash systems for a driver in the event of a collision can be optimized by an adapted degree of use of an intervention with regard to crash loads and driving position. . For example, when tripping safety devices, the driving position can be taken into account, ie manually or at least partially automatically. Measures before a collision on a driver's side, such as seat adjustment before the collision, belt forces and the like, can for example only be limited in manual driving position or remain, in order to avoid an impact on the driving task. Thus, in particular in the case of at least an automatic driving position on the driver's side, the use of safety devices in the event of a collision can be increased. Furthermore, an integrated security system can be realized. In addition, in a method similar to embodiments, a control device according to embodiments is easy to supplement or alternatively implement.
    A method for setting a control signal for controlling at least one safety device of a vehicle is presented, the method having the following steps: Inputting a driving mode signal [driving mode signal], the driving mode signal representing information as to whether a manual driving mode or at least partially automatic driving mode is set in the vehicle ; and adjusting at least one parameter of the control signal using the travel mode signal, to set the control signal.
    This method can, for example, be implemented in software or hardware or in a mixed form of software and hardware, for example in a control device. The vehicle may involve a motor vehicle, in particular a street vehicle, such as a car, truck or commercial vehicle. The at least one safety device may have an actuator, an actuator, a release element or the like. In this case, the at least one safety device can be triggerable before and in addition or alternatively in the event of an accident with the vehicle. At the step of the adjustment, a parameter set or set of parameters for the control signal can be adjusted. By adjusting the at least one parameter, the control signal can be set so that an activation of the safety device adapted to the current driving position takes place.
    According to one embodiment, in the step of the adaptation, at least one parameter can be adapted, which can affect a tripping of at least one intended safety device for a driver of the vehicle. The at least one safety device may, for example, be designed to adjust a driver's seat, a seat belt or the like. Such an embodiment provides the advantage that a driver, depending on the extent of a driving task depending on the driving mode, can be reliably protected against accidents. In this case, the safety device according to various embodiments can be designed to develop its protective effect even before an accident or during an accident.
    According to one embodiment, the safety device can thus be configured to carry out a pre-crash intervention with a level dependent on the driving position. With a pre-crash intervention it can be understood that the safety device is triggered even before an accident, for example a collision, to protect the driver from the consequences of the impending accident. When the safety device is configured, for example, to perform an engagement on the seat of the vehicle, the level of the safety device may, for example, refer to a seat position or seat adjustment, which can be adjusted depending on the driving position. When the safety device is configured to perform an engagement on the belt in the vehicle, the level of the safety device may, for example, refer to a belt force, which can be adjusted depending on the driving position. Thus, the step of the adjustment can be adjusted at least one parameter of the control signal, which affects a setting of the level of the safety device. In this way, a pre-crash operation, which can for example refer to the seat or belt, can be controlled with at least two levels depending on the driving position.
    In the adaptation step, at least one parameter is adapted, which can affect a single setting of a force, a speed an acceleration, a maneuvering path, a single displacement path and supplementary or alternatively a time for a tripping of the at least one safety device. Such an embodiment offers the advantage that a tripping ratio of the at least one safety device can be matched exactly with the present driving position.
    In the step of loading, a driving position signal can also be read, which has a first value when a manual driving mode of the vehicle is set, and has a second value, when at least partially automatic driving mode of the vehicle is set. The supplementary can driving mode signal optionally has at least one additional value, when a different driving mode is set different from the manual and the at least partially automatic driving mode. Such an embodiment offers the advantage that an actual present or set driving mode can be detected in a simple and reliable manner.
    In this case, in response to the first value of the read driving position signal in the step of the reading in the step of adapting the at least one parameter, the first parameter value can be set. In this case, the first parameter value in the case of a control of the at least one safety device can cause a partial tripping of the at least one safety device. A partial release can be understood to mean a release with limited force, limited speed, limited acceleration, limited operating path, limited displacement path and additional or alternatively limited duration. For example, the safety device is triggered by a partial release, as opposed to a complete release only partially or slower. Such an embodiment provides the advantage that the driving task in a manual drive at the partial release of the at least one safety device can be felt to the greatest possible extent, the then safety device, in contrast to a complete trip, affects the driver less strongly.
    Furthermore, in response to the second value of the read-driving mode signal in the step of reading, the step of adjusting the at least one parameter can be set to another parameter value. In this case, the second parameter value can, in the case of a control of the at least one safety device, bring about a complete tripping of the at least one safety device. In full trip, a trip with maximum force, maximum speed, maximum acceleration, maximum maneuvering path, maximum displacement path and supplementary or alternative maximum duration can be understood. A full-triggered effect of the safety device exceeds a partial-triggered effect of the safety device. Such an embodiment offers the advantage that in the case of at least partially automatic or highly automated driving, a maximum protective effect of the safety device can be called off.
    The method may include a step of providing the driving mode signal under use of a driving mode device [driving mode device] belonging to the vehicle. The driving mode device may be constituted by or have a vehicle control device, a user input interface or the like. Thus, the driving mode signal may represent a single sensor signal and supplementary or alternatively a user input signal. Such an embodiment provides the advantage that a secure identification, detection or determination of a selected driving mode can be realized.
    It has the presented method further creates a control device, which is configured to carry out, control and implement the steps in a variant of a method presented here in corresponding devices. Also by this embodiment variant of the invention in the form of a control device, the task underlying the invention can be solved quickly and efficiently.
    In addition, the controller may have at least one computer unit for processing signals or data, at least one memory unit for storing signals or data, at least one interface for a sensor or an actuator for reading sensor signals from the sensor or for reading control signals to the actuator and / or at least one communication or publishing data, which are embedded in the communication protocol. The computer unit may be, for example, a signal processor, a microcontroller or the like, the memory unit may be a flash memory, an EPROM or a magnetic memory unit. The communication interface may be designed to read or output data wirelessly and / or wired, wherein a communication interface may read or publish the wired data, read this data for example electrically or optically from a corresponding data transmission line or output it into a corresponding data transmission line.
    By a control device can be understood the present an electrical apparatus, which processor sensor signals and depending thereon provide control and / or data signals. The controller may have an interface, which may be hardware and / or software designed. In the case of a single hardware design, the interfaces can, for example, be part of a so-called system ASIC, which contains various functions of the control device. However, it is also possible for the interfaces to consist of own, integrated switching circuits or at least partially discrete construction elements. In a software design, the interfaces can be software modules, which are present, for example, on a microcontroller as well as other software modules.
    In an advantageous design, a control of at least one safety device belonging to a vehicle or at least one setting of a control signal for controlling at least one safety device belonging to a vehicle takes place through the control device. For this purpose, controllers can use, for example, input signals or sensor signals such as a single-user input signal, an image signal from a camera or the like which registers the vehicle interior. The control of the at least one safety device takes place through actuators such as setting motors, ignitable propellant charges or the like. A single safety device in the form of an airbag can then have several steps, for example up to three steps. According to one embodiment, the steps intended for activation can be selected depending on the exit mode. Similarly, a safety device in the form of an electric belt can control different power levels. According to one embodiment, a power level can be selected depending on the driving position.
    Advantageously, there is also a computer program product or program code with a program code, which may be stored on a machine readable carrier or storage medium such as a semiconductor memory, a hard disk memory or an optical memory and used for carrying out, reacting and / or controlling the steps of the method according to any of the above described embodiments. in particular when the program product or program is executed on a computer or device.
    Exemplary embodiments of the process presented herein are shown in the drawings and are further illustrated in the following description. They show: Fig. 1 a schematic representation of a vehicle with a steering device according to an exemplary embodiment; 2 is a flow chart of a setting method according to an exemplary embodiment; and Fig. 3 is a flow chart of a parameter matching process according to an embodiment.
    In the following description of advantageous exemplary embodiments, the same or similar reference numerals are used for the elements shown in the similar figures and act in a similar manner, whereby a repeated description of these elements is dispensed with.
    Fig. 1 shows a schematic representation of a vehicle 100 with a control device 120 according to one embodiment. The vehicle 100 is, according to the exemplary embodiment shown in Fig. 1, a motor vehicle in the form of a street vehicle, in particular a passenger car or the like, which is only exemplified as a left-hand drive vehicle. In the vehicle 100, according to the embodiment shown in Fig. 1, a driver 102 is arranged on a driver's seat 104.
    The vehicle 100 has the controller 120 and exemplified only one safety device 130. According to the exemplary embodiment shown in Fig. 1, the vehicle 100 has a single-drive position device 110 therefor. The control device 120 is signal-transmissively connected to the safety device 130. Furthermore, the control device 120 is signal-transmissively connected to the driving position device 110.
    The driving position device 110 is designed to identify or detect a driving position of the vehicle 100. The driving position is, for example, a manual driving position or an at least partially automatic or highly automated driving position. In the manual driving mode, it is a higher number of driving tasks to be taken over by a performer 102 than in the at least partially automatic driving mode. In the at least partially automatic driving mode, the vehicle 100 can be steered highly automated or partially automated using a suitable control device, so that the driver 102 does not have to take over any driving tasks or less driving tasks compared to the manual driving mode. The driving mode device 110 is configured to output or provide a driving mode signal 115. The driving mode signal 115 represents an information as to whether the manual driving mode or the at least partially automatic driving mode is set in the vehicle 100.
    The safety device 130 is assigned to the driver 102 and the additional or alternate driver seat 104. Thereby, the safety device 130 is configured to protect the driver 102 in the event of an accident with the vehicle 100. In addition, the safety device 130 is specifically configured to actuate the driver 102. For example, the safety device 130 is configured. affecting, changing or maintaining a driver's position 102 in relation to the vehicle 100, in particular to the driver's seat 104. The safety device 130 may also be configured, to change the position of the driver 102 by changing a setting of the driver's seat 104. The safety device 130 is releasable before and / or at an accident with the vehicle 100. The safety device 130 is designed, for example, as a device for pre-tensioning a seat belt, a device for displacing the driver's seat 104 and / or another safety device. A control or tripping of the safety device 130 takes place through a control signal 135. Thus, the safety device 130 is controllable and triggerable, respectively, through the control signal 135.
    The controller 120 is configured to set the control signal 135 for controlling the smallest safety device 130 associated with the vehicle 100. In addition, the controller 120 is configured to set the control signal 135 using the travel position signal 115.
    The controller 120 has a reading device 122 and an adjusting device 124. The reading device 122 is configured to read the driving position signal 115. Further, the reading device 122 is configured to pass on information regarding the set driving position to the adapting device 124. The adapting device 124 is configured to be configured. parameters for the control signal 135 during the use of the travel mode signal 115 and the information represented by the travel mode signal, respectively. By adjusting the at least one parameter, the steering 135 can be adjusted so that, taking into account the current driving position, optimal safety for the driver can be guaranteed through the safety device 130.
    Thus, the adjusting device 124 is configured to adjust at least one parameter, which affects a tripping and a tripping ratio, respectively, of the safety device 130 intended for the driver 102 by the vehicle 100. The adjustable parameter at least one through the adjusting device 124 is adapted to control the safety device 130 by means of the control signal 135. setting of a force, a speed, an acceleration, an actuating path, a displacement path and / or a time for a tripping of the safety device 130.
    According to one embodiment, the controller 120 may be configured to provide the control signal 135 with the at least one matched parameter. Optionally, the controller 120 may be configured to receive the control signal 135 from an interface to a single vehicle device and provide or output the control signal 135 with the at least one matched parameter.
    With regard to the operation of the control device 120 in the vehicle 100, it should be pointed out here that the read-in or read-in driving position signal 115 which can be read or read in represents a first value or a second value. The first value is present, regardless of the manual driving mode set by the vehicle 100, the driver 102 having a maximum number of driving tasks to take over. The second value is present if an at least partially automated driving position is set in the vehicle 100, the driver 102 having a minimum number of driving tasks to take over. When, by means of the input device 122, a driving position signal 115 has been loaded with the first value, the at least one parameter is set by means of the adapter 124 to a first parameter value. In a control of the safety device 130, the first parameter value produces only a partial tripping of the safety device 130. When by means of the reading device 122 a driving position signal 115 has been loaded with the second value, by means of the adjusting device 124 the at least one parameter is set to a second parameter value. The second parameter value causes, in a control of the safety device 130, a complete tripping of the safety device 130, which exceeds the partial tripping. Fig. 2 shows a flow chart of a method 200 for setting according to one embodiment. The setting 200 method is feasible, for setting a control signal for controlling at least one safety device belonging to a vehicle. In this case, the method 200 for setting in connection with the control device or using the control device from Fig. 1 or a similar control device can be carried out. Thus, the method 200 for setting in connection with the vehicle of Fig. 1 or a similar vehicle is feasible.
    The setting method 200 has a step 210 with the reading of a driving mode signal. The driving mode signal read in the step 210 with the reading represents an information as to whether a manual driving mode or an at least partially automatic driving mode is set in the vehicle.
    In a step 220 executable following the reading 210 with the read-in while the fitting is adapted to the method 200 for setting at least one parameter regarding the control signal using the driving position signal, to set the control signal. In other words, the at least one parameter of the control signal is adjusted depending on the driving position signal. represented the driving mode.
    According to one embodiment, the setting method 200 also includes a step 230 of providing the driving position signal using a driving position device associated with the vehicle. In this case, the step 230 with the provision is feasible before the step 210 with the loading.
    Fig. 3 shows a flow chart of a parameter matching process 300 according to one embodiment. Process 300 is feasible, for adapting at least one parameter with respect to a control signal for controlling at least one safety device belonging to a vehicle during use of a driving position. In this case, the process 300 can be carried out in connection with the method for adjusting from Fig. 2 or a similar method and / or in connection with the control device or using the control device from Fig. 1 or a similar control device, respectively. The process 300 arrives at a branch point 310, at which it is determined whether at least partially automatic travel is present as the driving position.
    If the driving mode is not set to automatic driving, ie if manual driving is set as driving mode, then the process 300 switches to a block 322. In block 322 at least one parameter is set, for example force, speed, acceleration and displacement before a collision to a leveled level , to obtain a vehicle steering ability from the driver.
    When the driving mode is set to at least partially automatic driving, then the process 300 switches to a block 324. In block 324 at least one parameter is set, for example force, speed, acceleration and displacement before a collision at a high level, for example a whole amount with respect to on crash loads.
    In this case, in the process 300 for parameter adjustment, for example, two different parameter sets for actions on a driver's side before a collision depending on a driving position come into use. If an exemplary embodiment comprises an "and / or" interconnection between a first characteristic and a second characteristic, this must be read so that, according to an exemplary embodiment, one embodiment has both the first characteristic and also the second characteristic and according to a further embodiment either only the first characteristic or only the second sign.
