Abstract
An engine automatic control system for vehicles is adapted to automatically stop the engine when the vehicle motion is arrested, to automatically start the engine in response to operation of a starting mechanism for effecting start of the vehicle, and to maintain the engine rotation after start of the vehicle in dependence upon change of the level of speed pulses from a speed sensor assembly. The control system is arranged to be ineffective in its function for automatic stop of the engine when the speed sensor assembly is inoperative to maintain the engine rotation under the operative condition of the control system.
