Abstract

Cruise control system for motor vehicles is provided, which control system has a sensor device for measuring the vehicle's performance characteristics and for measuring the distance to a target ahead of the vehicle, a controller to control the vehicle's speed or acceleration as a function of the measured performance characteristics and distance data, and an input device for a shut-off command to shut off the controller. The control system also has a shut-off function to shut off the controller as a function of other operational commands from the driver, and the controller has a stop function for automatically braking the vehicle to a standstill. The input device for the shut-off command is deactivated if the stop function is active and the vehicle is stationary.

Dependent claims

A cruise control system for a motor vehicle, comprising:

a sensor device for measuring the vehicle's performance characteristics and the distance to a target ahead of the vehicle;
a controller for controlling at least one of the vehicle's speed and acceleration as a function of the measured performance characteristics and the distance to the target, wherein the controller has a stop function for automatically braking the vehicle to a standstill;
and
an input device for inputting a shut-off command to shut off the controller, wherein the shut-off function to shut off the controller is also triggered by at least one of selected operational commands from the driver other than an activation of the input device, and wherein the input device for the shut-off command is deactivated if the stop function of the controller is active and the vehicle is stationary.
