A signal generator connected mechanically to a vehicle wheel is coupled to electronic circuitry that actuates an item of vehicle equipment when a predetermined vehicle speed is attained. The system can be used to control ignition-timing, throttle-blade-positioning, exhaust-gas-recirculating, door-locking, speed-warning or speed-limiting equipment. The electronic circuitry is coupled to individual actuators that connect or disconnect power sources to the vehicle equipment when vehicle speed has attained predetermined values.
