Abstract
A method and device for regulating the speed of a motor vehicle, wherein an electronic device a) compares deceleration of a vehicle with a threshold value immediately after a driver switches off a cruise control system and b), if the deceleration exceeds the threshold value, sends a torque demand signal to a powertrain component to reduce the vehicle deceleration to the threshold value or below. The electronic device may further c) compare vehicle acceleration with a second threshold value when the driver switches off the cruise control system, and d), if the acceleration exceeds the second threshold value, send a braking demand signal to a vehicle brake to reduce the vehicle acceleration to the second threshold value or lower.
