Stop/start device for controlling the functions of an internal combustion engine for motor vehicles

摘要

The stop/start device comprises a monitoring and control unit (11) which, by means of suitable actuation means (12), automatically shuts down the engine of the vehicle when appropriate sensors (1 to 5) indicate that the engine of the vehicle is moving, the clutch is engaged, the transmission is in the idling position and the speed of the vehicle is below a predetermined value. …The monitoring and control unit (11) subsequently causes the engine of the vehicle to be started up again with the aid of the electric starter motor (16) when the clutch pedal is pressed and the engine speed is below a predetermined threshold value. …The stop/start device also comprises a position sensor (6) which is assigned to the acceleration pedal, and comprises a disconnection device (20) by means of which the idling line (21) of the engine carburettor or fuel mixer can be disconnected. This disconnection device (20) is activated by the monitoring and control unit (11) when the speed of the engine of the vehicle is above a predetermined value and the acceleration pedal is released. …The disconnection device (20) is deactivated again and permits the engine of the vehicle to be restarted when the speed of the engine drops below a second predetermined value which is smaller than the aforesaid predetermined value. ……
