METHOD AND SYSTEM FOR ADAPTIVELY CONTROLLING DISTANCE AND SPEED AND FOR STOPPING A MOTOR VEHICLE, AND A MOTOR VEHICLE WHICH WORKS WITH SAME
First Claim
1. A method for stopping a motor vehicle which has an electronic surroundings control unit for evaluating the data from one or more surroundings sensors and which has an electronic brake control unit for activating a brake system, which electronics surroundings control unit and electronic brake control unit exchange information and/or commands via a data connection, in particular a vehicle data bus, comprising:
- measuring a separation distance to an obstruction, in particular to a vehicle traveling ahead,determining the traveling speed of the motor vehicle,regulating the separation distance to the obstruction by the surroundings control unit if the traveling speed exceeds a handover threshold value, andstopping the motor vehicle by the brake control unit if the traveling speed is less than or equal to the handover threshold value, wherein, as a function of the measured separation distance, the surroundings control unit predefines for the brake control unit a target distance at the end of which the vehicle should be stationary.

Abstract
A method for stopping a motor vehicle, having an electronic environmental control device for evaluating the data of one or more environmental sensors, and an electronic braking control device for actuating a braking system, these exchanging information and/or instructions via a data bus. The method comprises: acquiring a distance to a vehicle travelling ahead; determining the motor vehicle travel speed; controlling the distance to the obstacle using the environmental control device if the travel speed exceeds a transfer threshold value; and stopping the motor vehicle using the braking control device if the travel speed is less than or equal to said transfer threshold value. Depending on the acquired distance, the environmental control device determines a target path for the braking control device at the end of which the motor vehicle should be stationary. The invention also relates to an electronic control device for a braking system, and a motor vehicle.

- 10. An electronic control unit of a brake system for a motor vehicle, comprising an interface to a vehicle data bus, an interface to at least one wheel rotational speed sensor, and means for driver-independent activation of at least one brake actuator, comprising a stopping distance regulator which adjusts the deceleration and/or the speed of the motor vehicle as a function of the traveling distance covered in order to stop the motor vehicle within a predefined target distance.
