  • Patent number: 9796366
    Abstract: A braking device for a motor vehicle has a setpoint controlled deceleration device, which, upon receipt of a braking request input by a driver or an assistance system, for example, on the basis of a difference between a setpoint value and an actual value, drives a brake of the vehicle to generate a setpoint controlled braking torque for a deceleration of the motor vehicle. In addition, the braking device has a braking preparation control, which, upon receipt of a braking preparation signal, drives the brake independently of the setpoint value to produce at least one braking pressure for generating a preparation braking torque for a pre-deceleration of the motor vehicle. The braking preparation signal is generated as soon as a driving situation is ascertained where a braking request input by a driver or an assistance system is very likely imminent.

  • Patent number: 8036803
    Abstract: Adaptive cruise control (ACC) system for motor vehicles is provided, the ACC system having a sensor system for acquiring data concerning a target object and the own (host) vehicle, an actuator system for controlling the longitudinal movement of the vehicle, and a controller that intervenes in the actuator system within certain intervention limits in order to maintain a defined, controlled target distance from the target object, and an output device for issuing a take-over request to the driver if the controlled target distance cannot be maintained. The ACC system further includes a prediction system for predicting a conflict situation in which the controlled target distance cannot be maintained, in which case the take-over request is initiated before the conflict situation actually occurs.

  • Patent number: 7706954
    Abstract: A speed controller for motor vehicles having an input device for the input of a desired speed Vset by the driver, and having a plurality of operating modes which are able to be activated in different speed ranges and differ in their functional scope. A change in the operating mode, which results in the loss of a safety-relevant function, is provided or enabled by a command of the driver, characterized by a decision unit, which, in the light of predefined criteria, determines whether a change in the desired speed Vset, which is input by the driver, is to be interpreted as a command for changing the operating mode.

  • 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.
