Abstract: A control system for vehicles equipped with an engine and an automatic transmission mechanism which has a non-running position and a running position one of which is selected by a driver of the vehicle and works to automatically change a speed of an output thereof. The control system basically inhibits the engine from being automatically stopped on an uphill road in order to minimize the rolling back of the vehicle upon start of the vehicle, but is responsive to the driver's intention to permit the engine to be automatically stopped, that is, the switching from the running position to the non-running position to stop the engine.

Abstract: An engine start system which may be employed in automotive idle stop systems. To start an engine, the system brings a pinion gear into engagement with a ring gear coupled to the engine and turns on an electric motor to rotate the ring gear through the pinion gear to crank the engine. When it is requested to start the engine during deceleration of the engine before stop thereof, the system thrusts the pinion into engagement with the ring gear and then turns on the motor to rotate the pinion gear, in other words, delays the activation of the motor until after the pinion gear has engaged the ring gear. This minimizes mechanical impact or noise arising from the engagement of the pinion gear with the ring gear and improves the reliability in engagement with the ring gear during the deceleration of the engine and durability of the system.
