A STOP-START DEVICE TO CONTROL THE OPERATION OF AN INTERNAL COMBUSTION ENGINE OF A VEHICLE PROVIDED WITH AN AUTOMATIC TRANSMISSION.

摘要

The device comprises sensors for providing electrical signals indicative of the speed of the vehicle, the speed of rotation of the engine, the position of the accelerator pedal and the position of the brake pedal. An electronic monitoring and control unit connected to these sensors, activates actuator devices arranged to turn off the engine when, for a period of time of predetermined duration, the speed of rotation of the engine is less than a first predetermined value, the speed of the vehicle is less than a threshold value, and the accelerator pedal is released. This monitoring and control unit deactivates the actuator means and activates the electric starter motor when the signals provided by the sensors indicate that the speed of rotation of the engine is lower than a second predetermined value, less than the first, and the accelelator pedal (or the brake pedal) is depressed.
