  • Publication number: 20060047390
    Abstract: A method for adapting a steering-wheel torque, driver-independently exerted on the steering wheel, in a lane-keeping support system of a motor vehicle includes determining a deviation variable that characterizes the lateral vehicle deviation from an ideal line, and exerting a driver-independent steering wheel torque on the steering wheel as a function of the determined deviation variable. In this manner, the torque is adapted to the lane width.

  • Patent number: 6853906
    Abstract: A method and a device are described for determining a future travel-path area of a first vehicle, which is furnished with a distance sensor. In this context, using the distance sensor at pre-established or selectable time points, at least relative positions are determined of at least one vehicle traveling ahead with respect to the first vehicle. At least these determined relative positions are stored in at least one storage device. These relative positions, stored in the storage device, constitute in each case a course path of the corresponding vehicle traveling ahead. The future travel path area of the first vehicle is determined at least on the basis of the course path of the vehicle traveling ahead. The course path of the vehicle traveling ahead is projected in the direction of the position of the first vehicle.

  • Patent number: 6853903
    Abstract: A method of cruise control and distance regulation in motor vehicles, in which the distance from a vehicle driving in front is measured, and at least two operating modes (e.g., ACC and stop and go) are provided for the distance regulation, these modes being activatable in different overlapping speed ranges, and in which it is possible to switch between these operating modes in at least one direction only by a command by the driver. The speed of the vehicle driving in front is extrapolated into the future on the basis of the speed of one's own vehicle and the measured distance data and/or the relative speed data, and a switch prompt is output to the driver when the extrapolated speed is outside the allowed range for the current mode, and the current speed is within the allowed range for the other mode.

  • Patent number: 6820709
    Abstract: A cruise controller is provided, which regulates the driving speed of the vehicle not only beyond a certain minimum speed but also at speeds below a preselected critical speed down to standstill of the vehicle. Detecting the traffic situation using a distance sensor allows the vehicle to be automatically started once the driver has responded to a corresponding starting instruction. The starting instruction is effective until a preselected time limit, but, alternatively may also be repeated. However, in any traffic situation, the driver may override the cruise controller by operating the accelerator pedal or the brake pedal.
