摘要:
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.

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.

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.

In the case of a method for hitching a trailer (2) to a motor vehicle (1), in particular a semitrailer to a semitrailer towing machine, an image sensor (5) is provided which is arranged in a hitching region (6) in such a manner that image data of the hitching region (6) are recorded. During the approach of the motor vehicle (1) to the trailer (2), stored model data of the hitching region (6) of the trailer (2) are segmented in the image data recorded by the image sensor (5) and are in each case placed in the correct position in the image data. 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.

The invention relates to a method for the predictive determination of the change in the yaw rate (ψ) 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 (ψ) 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.

A brake control system for a vehicle, in particular a commercial vehicle, includes a service brake for braking the wheels of the vehicle. To increase operating safety, the service brake is equipped with an electronically actuatable brake unit for each wheel for actuating the brake of the respective wheel. Two redundantly connected central control devices are connected via control lines to the brake units so as to actuate the brake units independently of one another.

A semitrailer train having a coupling part assigned to the towing vehicle and a coupling part assigned to the semitrailer. A control device for controlling components of the semitrailer is provided in the towing vehicle data lines transmit the control data and power supply lines to the components. The coupling part assigned to the towing vehicle is a fifthwheel pickup plate and the coupling part assigned to the semitrailer is a kingpin which matches said coupling part. An alternating voltage generator arrangement in the vehicle provides a modulated carrier signal and a transformer coil is arranged in the fifthwheel pickup plate of the towing vehicle in order to transmit the carrier signal with the control data modulated onto it to a transformer coil in the region of the kingpin of the semitrailer.
