Abstract
In a method for limiting the traveling speed of a motor vehicle to a variable maximum speed a limiting system action takes place in the situation where the speed demanded by the driver via the actual accelerator pedal position is higher than the preset maximum speed. In this case, taking account of vehicle state and operating variables, control signals can be produced in order to select a specific gear in the transmission. At the time when the preset maximum speed is switched off, an accelerator pedal substitute variable which correlates with the preset maximum speed is compared with an actual accelerator pedal position. When the actual accelerator pedal position is greater than the accelerator pedal substitute variable at the time when the maximum speed is switched off, a defined minimum gear is preset as the lower gear limit in the transmission.
