  • Patent number: 8378520
    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.

  • Publication number: 20090044041
    Abstract: A redundant data bus system has two data buses between which at least two failsafe control devices are connected. The two data buses operate with the same data bus protocol at essentially the same transmission frequency, and safety-related control messages are transmitted in parallel via both data buses and processed in the control devices. Each control device performs a separate control task via assigned control software. Each control device has two microcomputers which operate independently of one another and which have software for both the first and the second control tasks. When one control device fails, the control task can also be performed by the other. One data interface is arranged between the two microcomputers, via which result data calculated from the safety-related control messages can be exchanged and compared with one another. Based on such comparison a decision means determines which microcomputer or control device carries out a control task.

  • Publication number: 20080197698
    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.

  • Patent number: 7336805
    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.

  • Publication number: 20080033623
    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.

  • Publication number: 20070198190
    Abstract: A utility vehicle has an electronically controlled drive train which has at least one drive unit, one steering system and one braking system. In addition, the motor vehicle has a maneuvering assistance system with a display device, an input device and a control system. The display device displays an actual orientation and an actual position of the vehicle as well as the relatively close surroundings of the vehicle on a monitor. The input device inputs a desired orientation and a desired position for the vehicle. The control system processes a maneuvering algorithm and at the same time actuates the drive train to transfer the vehicle from its actual orientation and actual position into its desired orientation and desired position taking into account the vehicle surroundings.

  • Publication number: 20070174684
    Abstract: The invention relates to a method for logging messages on a data bus and temporarily storing the sent messages in a cyclically overwritable volatile storing means. The temporarily stored messages can be examined in a targeted manner for attributes of interest by using a verification program. A storage of the temporarily stored messages in a non-volatile second storing means can be initiated by means of definable trigger events that, for example, are formed from individual or a number of attributes of the messages. To this end, the occurrence of the defined trigger event is determined by a monitoring unit, and the data content of the volatile storing means are subsequently transferred into the storage locations of the non-volatile storing means. The principal advantage achieved with the above method resides in the possibility of backtracking the bus traffic.

  • Patent number: 7225891
    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.

  • Publication number: 20070090688
    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.

  • Patent number: 7204504
    Abstract: 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.
