ABSTRACT:
Method and apparatus are provided for limiting the speed of a motor vehicle. The method intervenes to limit the engine torque while the actual speed is still below the maximum speed, but yet a demand by the driver for a speed above the maximum speed is detected. In this case, an acceleration-regulating system intervention takes place first and, if the speed further approaches the maximum speed, a speed-regulating system intervention takes place, allowing the actual speed to be brought gently to the set maximum speed. In the case of speeds demanded by the driver which are below the maximum speed, the driving response remains determined solely by the driver. It is advantageous to combine the speed limitation with cruise control, with selective activation of one of the two operating modes.
