The Drive by Wire (DbW) Speed Control System, patent No PCT/GB2007/001751 Is designed for vehicles with an Engine Management system (EMS) euro 3 engines and above. The vehicle usually has an electronic accelerator pedal (i.e. without a mechanical throttle linkage), which are now standard on modern vehicles.
The Autokontrol DbW system’s electronic control unit (ECU) receives frequency signals while the vehicle is moving. At a pre-set frequency, which may be the legal maximum speed or the vehicle operator’s required set speed, the ECU transmits a signal to the EMS controlling the top speed.
