Abstract
The speed of the vehicle (2) is detected by the interaction of two radar beams (B, C) with a receiver located in the vehicle (2) receiving control signals from a central emitter, (1) so that the engine is controlled via a relay, to maintain the speed below a preset maximum. The vehicle receiver may re-transmit the signals received from the radar emitter (1) upon the vehicle (2) entering the surveillance area. Pref. when the transmitted signal is received the relay is released causing a control vane in the air intake to shut down so as to limit the speed of the vehicle engine, if the vehicle (2) enters the control zone at a speed above the preset maximum.
