The invention relates to a device for preventing selected users from
driving a vehicle above a particular speed. The speed limit value can be
programmed by the selected users by driving the vehicle at a desired
speed limit and providing programming instruction. The device provides,
from acceleration control signals received from the acceleration pedal,
altered acceleration control signals. When in non speed limiting mode,
the device simply forwards the acceleration control signals to the engine
control unit or the electronic throttle controller. When in speed
limiting mode, the device makes no change to the acceleration control
signals if the vehicle speed is below the speed limit value and alters
the acceleration control signals if the vehicle speed reaches the speed
limit value, in order to limit the speed of the car.
