  • Patent number: 7089101
    Abstract: The invention relates to a method for assisting the driver of a vehicle (10) when performing a driving maneuver, such as a parking or shunting maneuver. In this case, a reference trajectory (16) is determined, along which the vehicle (10) is to be moved. A steering wheel position to be set and controlling the vehicle along the reference trajectory (16) is indicated to the driver during the driving maneuver. The vehicle longitudinal speed is influenced independently of the driver in the event of a steering angle deviation between the actual steering angle actually set by the driver and the desired steering angle corresponding to the requested steering wheel position. As a result, the driver can be given a greater reaction time in order to set the indicated steering wheel position.

  • Patent number: 6926374
    Abstract: An automatic brake and steering system and method for a vehicle contains a sensor unit for sensing vehicle state and characteristic variables, and ambient conditions. Furthermore, a control unit and actuator devices are provided for setting the vehicle brake system and/or the vehicle steering system. In order to be able to carry out automatic avoidance maneuvers with maximum safety, an avoidance route is determined if there is an obstacle in the path of the vehicle. Thereby, if there is a further obstacle on the avoidance route, the strategy for determining the avoidance route is applied once more. If it is not possible to find a collision-free avoidance route, that route on which the difference between the remaining braking distance and the remaining distance from the obstacle is smallest is selected.

  • Patent number: 6449572
    Abstract: In a method for classifying the driving style of a driver in a motor vehicle, measured variables indicative of driving style are recorded and driving-style classification figures are determined by a comparison with reference values, parameter settings corresponding to the driving-style classification figures being carried out to adapt the functioning of a regulation and control unit. In order to improve the handling of a motor vehicle with the aid of a driver classification, it is provided that presettings for the driving-style classification figures are stored in the regulation and control unit of the motor vehicle, it being possible to prescribe driving-style classification figures for a plurality of different driver reaction stages, and that the current driver is classified in a prescribed driver reaction stage in the motor vehicle by measuring classifying indicators, and driving-style classification figures corresponding to the driver reaction stage are activated in the regulation and control unit.
