Definitions
- the motor vehicle also has several X-by-Wire control devices. This refers to control devices that are controlled exclusively electrically, i.e. have no mechanical fallback level.
- the X-by-wire control devices include, for example, one or more brake-by-wire control devices, one or more steer-by-wire control devices and/or one or more shift-by-wire control devices.
- the control devices can be aimed at braking, steering or switching or can carry out this at least temporarily.
- the brake-by-wire control devices are used for braking, the steer-by-wire control devices are used for steering and the shift-by-wire control devices are used for shifting.
- Each brake-by-wire control device includes one or more wheel brakes with brake actuators, which are controlled purely electronically.
- the steer-by-wire control devices each have a steering actuator, by means of which a steering angle of the motor vehicle can be adjusted and which are also controlled exclusively electronically.
- the shift-by-wire control device has a shift actuator, which is arranged in a manual transmission of the motor vehicle.
- the manual transmission is used to set a gear selected from several different gears or a corresponding gear ratio between the drive unit or one the drive units and at least one driven wheel of the motor vehicle.
- the shift actuator is intended and designed to set the selected gear or the selected translation on the manual transmission.
- the shift actuator is also controlled purely electronically.
- Each of the X-by-Wire control devices is intended and designed to influence the ferry operation of the motor vehicle, for example for braking, steering or switching.
- Each of the control devices has, for example, a control element which is arranged in a passenger compartment of the motor vehicle and which is operatively connected to an actuator of the motor vehicle purely electronically, i.e. without a mechanical fallback level. Control devices of the same type can of course use the same control element.
- the brake-by-wire control devices are controlled together by means of a brake operating device, in particular a brake pedal.
- the steer-by-wire control devices have a common steering control device, in particular a common steering wheel or the like.
- the actuator is, for example, the wheel brake or one of the wheel brakes, the steering actuator or the switching actuator.
- a mechanical connection between the respective control element and the respective actuator is always available, at least as a fallback level.
- An electronic control of the respective actuator can also be provided, for example a brake booster, a power steering or the like is operated electrically. This means that even if the power supply fails, the motor vehicle can be operated reliably, namely via the mechanical fallback level, although this may require greater effort.
- each of the control devices transmits a status message to the central computing device at least temporarily.
- the status messages are transmitted from the respective control device to the central computing device periodically or permanently. In the case of periodic transmission, the interval between successive transmissions of the status message is dimensioned such that, even if a malfunction suddenly occurs, the central computing device can initiate countermeasures in sufficient time to ensure the safety of the motor vehicle.
- the central computing device is preferably separate from the control devices, and therefore represents an additional device of the motor vehicle.
- the central computing device and the control devices are connected to one another in terms of communication technology, in particular via a bus system, for example via a CAN bus or Flexray bus.
- one of the control devices has the central computing device or takes over its tasks.
- the control device and the central computing device are formed by different circuits, so that a defect in the control device does not also mean a defect in the central computing device.
- the central computing device is part of a control device of the drive device, which can also be referred to as an engine control device. In this case it is ensured that if the central computing device is defective, the engine control unit is inoperative and the drive device is therefore out of operation.
- the central computing device receives the status messages transmitted by the control devices and uses them to determine the overall status. This means that the overall status depends on all status messages transmitted by the control devices. The absence of status reports from one or more of the control devices can also be included in the overall status.
- the overall status is as follows Function of status messages.
- the overall status describes the overall condition of the several X-by-Wire control devices and consequently the technical equipment of the motor vehicle.
- the central computing device controls the drive device and/or the control devices based on the overall status, in particular to influence the ferry operation of the motor vehicle. This is preferably to be understood as meaning that the central computing device transmits a control command to the drive device and/or the control devices, which depends on the overall status.
- the drive device and/or the control devices are in turn controlled depending on the transmitted control command. Based on the control command, for example, activation of the drive device is permitted or prevented or the drive device is deactivated. It can also be provided that one of the control devices is controlled based on the control command to influence the ferry operation of the motor vehicle, for example for braking, steering or switching.
- the central computing device which can also be referred to as a central coordinator, is therefore used to collect and summarize the status reports into the overall status and to control at least one device of the motor vehicle, namely the drive device and/or the control devices. This implements central control of the motor vehicle to ensure its safety at all times.
- the central computing device can be used to provide a consistent display for the user of the motor vehicle, which is not based on the individual status messages, but rather on the overall status. The display of different status messages from the control devices, which can be confusing for the user, is therefore avoided. Overall, safe and consistent operation of the motor vehicle is achieved.
- each of the control devices carries out a self-diagnosis and based on a result of the Self-diagnosis determines a control device state and / or a remaining running size of the motor vehicle, which is transmitted to the central computing device as part of the respective status message.
- the remaining running size is in particular a remaining running time or a remaining running distance.
- the remaining running time describes the travel time that is still permissible and the remaining travel distance describes the travel distance that is still permissible.
- the self-diagnosis is used to determine a status of the respective control device. If, as part of the self-diagnosis, it is determined that the respective control device can be operated properly, this is recorded as part of the control device status and transmitted to the central computing device as a status message. However, if it is determined during the self-diagnosis that there is an error in the respective control device, the error is recorded in the control device state.
- a further development of the invention provides that the overall state is set to a first overall state value, provided that the control device states have values that correspond to functional control devices, and / or the power supply device state has a value that corresponds to a functional power supply device, and / or that the overall state a second overall state value is set if one of the control device states has a value that corresponds to a non-functional control device, and / or the power supply device state has a value that corresponds to a non-functional power supply device.
- the overall state only has the first overall state value if all control device states or the power supply device state indicate the functionality of the respective device.
- the overall state is already set to the second overall state value if only one of the control device states and/or the power supply device state has the value that indicates a non-functional device. Consequently, a high level of safety of the motor vehicle is achieved.
- a further development of the invention provides that the total remaining run size is set to the smallest value of the remaining run sizes and/or the further remaining run size. This has also already been pointed out. Using the smallest value for the total remaining run size has the particular advantage that the user of the motor vehicle is always shown the remaining run size over which the motor vehicle can still be operated reliably and safely.
- the drive device If the drive device is deactivated, its activation is only permitted if the overall state indicates that proper operation of the control devices or the power supply device is possible and consequently the overall state has the first overall state value and / or the total remaining run size has not yet expired. If the overall state does not have the first overall state value or the total remaining run size has expired, activation of the drive device is prevented.
- the procedure described is applied with the drive device activated.
- the drive device and/or the control devices are activated to stop the motor vehicle. Otherwise, ferry operations will continue.
- Such a procedure has the advantage that starting the motor vehicle is not permitted if one of the control devices is defective or that the ferry operation of the motor vehicle is ended immediately or with a time delay when the defect occurs. This ensures a high level of safety for the motor vehicle.
- a further development of the invention provides that several of the following devices are used as control devices: brake-by-wire control device, steer-by-wire control device and shift-by-wire control device. The different control devices have already been pointed out.
- a further development of the invention provides that the overall status is displayed to a user of the motor vehicle using a display device.
- the display device is, for example, an optical, acoustic and/or haptic display device.
- the overall condition and/or the overall remaining mileage of the motor vehicle are displayed to the user.
- the use of the overall status for the display device has the advantage that a uniform and consistent display is made to the user. This avoids displaying individual status messages from the control devices, which can be inconsistent and confusing for the user.
- Figure 1 shows a schematic representation of a motor vehicle which has a drive device and several X-by-wire control devices.
- FIG. 1 shows a schematic representation of a motor vehicle 1.
- the motor vehicle 1 has a display device 2 which is arranged in an interior, in particular in a passenger compartment, of the motor vehicle 1.
- the display device 2 is preferably located on a dashboard of the motor vehicle 1.
- the motor vehicle 1 has a drive device 3 and a driver assistance device 4.
- a power supply device 5 and several X-by-wire Control devices 6 part of the motor vehicle.
- Several of the control devices 6 are available as brake-by-wire control devices 7 and several as steer-by-wire control devices 8.
- the control devices 6 are designed to be redundant.
- the control takes place in such a way that the drive device 3 is either released for activation or activation is prevented depending on the overall status.
- Activation is understood to mean preparing for the provision of a drive torque aimed at driving the motor vehicle. If activation of the drive device 3 is prevented, it cannot provide the drive torque, so that the motor vehicle 1 remains at a standstill. If the motor vehicle 1 is already in motion, it can be provided, depending on the overall status, to control the driver assistance device 4 to brake the motor vehicle 1.
- the driver assistance device 4 controls the corresponding control devices 6, more precisely the brake-by-wire control devices 7.
- not only one of the brake-by-wire control devices 7, but several, in particular all, of the brake-by-wire control devices 7 are controlled for braking the vehicle 1. This results in reliable operation of the motor vehicle 1.
