摘要:
The invention relates to a method for energy management, whereby large variations in current draw in the loom are reduced, in particular current draw spikes, caused by very high making currents for electric actuators and solenoid valves, which are more evenly distributed over time. The above is achieved, by means of a predictive working of said method for energy management, by determination of both energy available in the subsequent period and the energy requirement, based on switch-on requests and selects users for switching on, according to the priority thereof and an actual tolerance time, within which a user must be switched on at the latest, following the declaration of a switching-on request for the same. The tolerance time is continuously updated.

A method for operating a software module on a processor unit in a vehicle optimizes the processor utilization level in networked controllers. The controller on which the software module is operated is selected based on the available computation capacity of the controllers which are currently in operation.

A system for coupling a trailer (2) to a motor vehicle (1), in particular a trailer (2) to a motor tractor (1), is provided with an image sensor (5), which is located in the coupling area. The coupling process involves connecting a trailer coupler (4) of the motor vehicle (1) and a tow bar (3) of the trailer (2), which is detected by an image sensor (5) detecting a movement of a locking element (8) associated with the trailer coupling (4). Thereupon a process of braking of the motor vehicle (1) is initiated.

Many day-to-day driving situations require that an operator of a motor vehicle guide the motor vehicle along a specific course and bring the vehicle to a stop at a specific location, for example in a parking bay or at a loading platform. To assist a vehicle operator in such situations, a method and a suitable device for implementing this method, include detecting the potential target objects in the image data of an image sensor and identifying the potential target objects as potential destinations in a multi-stage exclusionary method, whereupon a trajectory describing an optimized travel path is computed at least in relation to the most proximate destination. By using the multi-stage exclusionary method according to the present invention, it is possible to reliably identify potential destinations in complex image scenarios solely on the basis of their geometric form, even when the destinations have not been encoded by specific symbols.

A device is provided for predictively detecting and avoiding motor vehicle collisions, including a control device, a sensor system for sensing obstacles in the surroundings of the vehicle, and a signal transmitter system for audibly and/or visually signaling a significant risk of collision between the vehicle and an obstacle. In order to increase the field of application of such a device, the vehicle can be a utility vehicle, the sensor system being divided into a front sensor arrangement which is arranged in the region of the front of a vehicle, and a rear sensor arrangement which is arranged in the region of the rear of a vehicle. The front sensor arrangement is connected to the control device via a data bus, while the rear sensor arrangement is connected to the control device via a power line communication.

A safety device for, in particular, nonrailborne vehicles, having a monitoring device to monitor a hazardous area and additionally the road area, located on the opposite side of the hazardous area viewed from the vehicle and adjoining the hazardous area. Obstacles in the hazardous area and/or road area are detected. An output signal is brought about if an obstacle which prevents the hazardous area being traveled through completely has been detected.

The invention relates to an array of control devices having a plurality of control devices (1-3, 20-23) which are interconnected via a first data bus (4), in a means of transportation, control devices (1-3; 20-23) which are of redundant configuration with respect to a control function being provided, and in each case a data bus isolating switch (5) being assigned to the control devices (1-3; 20-23) which are of redundant configuration, said data bus isolating switch(s) connecting or disconnecting the data bus (4) as a function of an evaluation signal. In order to optimize the redundant array, each of these data bus isolating switches (5) is connected to a signal line of at least one further redundant control device (1-3; 20-23), a further redundant control device (2, 3; 21; 23) transmits an evaluation signal to the data bus isolating switch (5) which is assigned to a first redundant control device (1; 20; 22), the evaluation signal being the result of functional checking of the further redundant control device (2, 3; 21; 3) with respect to the first redundant control device (1; 20; 22). The data bus isolating switch (5) of the first redundant control device (1; 20; 22) disconnects the data bus (4) as a function of the result of a logic circuit, at least one input signal of the logic circuit being formed by the at least one evaluation signal.
摘要:
A brake system for a vehicle can be operated without a driver. It has a service brake device, a parking brake device and an emergency braking device. At least the wheel brake devices of the wheels of one axle of the vehicle have emergency brake actuators which switchover the assigned wheel brake devices into the braking state as a result of the triggering of an emergency braking operation. The emergency braking operation can be triggered either manually by means of an emergency operator control device or automatically by means of a monitoring device if the latter has detected an unacceptable operating state of the vehicle in the driverless operating mode.

The device according to the invention relates to a device for evaluating and/or influencing a vehicle movement variable and/or the vehicle movement behavior. For this purpose, the device has the following means: operator control means (10) with which the driver can generate predefined values (VG) for influencing at least one vehicle movement variable. Evaluation means (42, 44, 46, 48) with which the behavior of a vehicle movement variable with respect to a predefined value is evaluated, and/or with which the vehicle movement behavior is evaluated with respect to a predefined vehicle movement behavior as a function of vehicle movement variables and/or of variables which represent the surroundings of the vehicle. These evaluation means (42, 44, 46, 48) can be operated in at least two different operating states, only an information item (OHAx) relating to the behavior of the vehicle movement variable and/or relating to the vehicle movement behavior being made available to the driver in a first operating state as a function of the result of the evaluation which is carried out, and output signals (AGSx) for influencing a vehicle movement variable and/or the vehicle movement behavior independently of the driver being determined in a second operating state as a function of the result of the evaluation which is carried out. In addition, the device has influencing means (40) by means of which the driver can switch over the evaluation means (42, 44, 46, 48) between the at least two operating states. There is also provision of processing means (12, 14, 16, 18, 20, 22) with which actuation signals (ASSx) for actuating actuators (26, 28, 30) which are arranged in the vehicle are generated on the basis of the predefined values (VG) which are generated by the driver and/or, if the evaluation means (42, 44, 46, 48) are operated in the second operating state, on the basis of the output signals (AGSx). The actuation of the actuator (26, 28, 30) influences the vehicle movement variable and/or the vehicle movement behavior.
