US 9,358,962 B2 · Method and system for adaptively controlling distance and speed and for stopping a motor vehicle, and a motor vehicle which works with same

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.

Dependent claims

A method for stopping a motor vehicle that includes a surroundings control unit and a brake control unit, the method comprising:

measuring, by the surroundings control unit including one or more surrounding sensors, a separation distance to an obstruction, in particular to a vehicle traveling ahead,
determining, by the surroundings control unit, a traveling speed of the motor vehicle,
regulating, by the surroundings control unit, the separation distance to the obstruction when the traveling speed exceeds a handover threshold value, and
stopping the motor vehicle, by the brake control unit when 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 the motor vehicle travels at the end of which the vehicle should be stationary, and
wherein the brake control unit adjusts the speed of the motor vehicle as a function of a traveling distance covered by the motor vehicle in order to stop the motor vehicle at the predefined target distance.

3 more elements

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, including:
one or more surrounding sensors, for measuring a separation distance to an obstruction, in particular to a vehicle traveling ahead,
a stopping distance regulator which, when the traveling speed is less than or equal to a handover threshold value, adjusts the deceleration and/or the speed of the motor vehicle as a function of the traveling distance covered by the motor vehicle in order to stop the motor vehicle at a predefined target distance the motor vehicle travels at the end of which the motor vehicle should be stationary.
