Abstract: The present invention discloses a method for energy management, by means of which significant fluctuations in the power consumption in the on-board electrical system are reduced, in particular, current consumption peaks arising due to a very high start-up current of electrical actuators and solenoid valves, are more evenly distributed over time. To achieve this, the method for energy management according to the invention operates predictively, i.e. it determines both the energy available in the subsequent time interval and the energy required on the basis of activation requests, and selects consumers to be activated according to their priority and a prevailing tolerance time within which a consumer must be activated following the submission of its activation request. The tolerance time is thereby continuously adapted.

Abstract: 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.

Abstract: 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.

Abstract: The invention relates to a method for the predictive determination of the change in the yaw rate (?) of a vehicle. According to said method, the progress of the build-up of the braking pressures (p1 to p4) of the wheel brakes is monitored, and the change in the yaw rate (?) of the vehicle is determined in a predictive manner from the progress of the pressure build-up before the vehicle rotates around the vertical axis thereof. The inventive method allows the driving stability of a vehicle to be better regulated.

Abstract: In a control system for a train composed of a towing vehicle and a trailer, the towing vehicle is equipped with an electronically actuatable drive train. A trailer steering angle actual value sensor determines a trailer actual steering angle of a wheel axle which steers the trailer. The driver of the vehicle can input a trailer setpoint steering angle via a trailer steering angle setpoint value sensor. A reversing device is provided which determines, from the trailer actual steering angle and the trailer setpoint steering angle, a modified towing vehicle setpoint steering angle of a wheel axle which steers the towing vehicle. In the active state of the reversing device, the modified towing vehicle setpoint steering angle takes the place of the present towing vehicle setpoint steering angle in a modified movement vector; and when the train is moving, it changes the trailer actual steering angle into the trailer setpoint steering angle when the modified movement vector is processed.

Abstract: A control system for a vehicle combination comprises a towing vehicle and a trailer, with an electronically activatable drive train. A manual operator control device, which is fixed on the towing vehicle, can be used by the vehicle driver to input a driving request for manual operation of the vehicle combination, from which request a standardized movement vector is generated. A control device (19), which is fixed on the towing vehicle, outputs control signals for activating the drive train based on an input movement vector. For the transmission of the control signals, the control device is coupled to the drive train, which processes the control signals to implement the driving request. To improve the functionality of the control system, a trailer coordination device, which is mounted on the towing vehicle, can be used to read in at least one trailer-specific actual value and pass on the actual value to the control device.

A target zone (9) for the hitching is determined therefrom. The arrangement of the target zone (9) in the image data is used as a measurement for a steering operation of the motor vehicle (1) during hitching.
