Engine automatic stop and starting device in vehicle
TLDR
In this paper, an ECU 10 determines braking force just enough to impede the movement of a vehicle according to the inclination of the road surface based on a road surface inclination sensor.Abstract:
PROBLEM TO BE SOLVED: To provide an automatic stop and starting device for an engine in a vehicle, that can shift from brake release more smoothly into an engine driving state. SOLUTION: An ECU 10 determines braking force just enough to impede the movement of a vehicle according to the inclination of the road surface based on a road surface inclination sensor 16, stops an engine 1 when braking force just enough to impede the movement of the vehicle by the operation of a brake pedal is applied, while monitoring the operating quantity of the brake pedal based on a brake pedal operating quantity sensor 15, determines braking force just enough to impede the movement of the vehicle according to the inclination of the road surface based on the road surface inclination sensor 16 after the stop of the engine 1, and restarts the engine when braking force becomes smaller than the braking force just enough to impede the movement of the vehicle. In this case, the ECU 10 restarts the engine 1 between the time of relaxation of braking force by the brake pedal and the time of release of the brake pedal.read more
