Abstract
The limiter is for the speed of vehicles based on the accelerator pedal travel and the speed of the vehicle, a comparator being used to allow the maximum allowable speed to be maintained. The limiter controls the degree of movement of the Bowden cable (12) connecting the pedal (1) to the carburettor inlet butterfly valve (2) or injector system. A tachometer or some other form of speed sensor (6) provides a speed related signal to a comparator (7) which has a predetermined speed stored in memory. The comparator output is used to control or drive a motor (10, this in turn adjusts the position of one end shoulder (13a) of the Bowden cable sheath via a worm gear (21) at the pedal end, the remaining shoulder (12b) being fixed. The stored speed can be adjusted or overridden by two manual switches to earth (8, 9).
