1. An engine automatic stop-restart control apparatus comprising:
- an engine control means for automatically stopping and restarting an engine;
an auxiliary braking force application for additionally applying an auxiliary braking force for preventing a vehicle from moving when the engine is automatically restarted after the engine is automatically stopped by the engine control means; and
an auxiliary braking force application determination means for determining whether to drive the auxiliary braking force application to apply the auxiliary braking force in accordance with a magnitude of a braking force generated by an operation of a braking force operation member.

Abstract
In an engine automatic-restart control apparatus for vehicles, a braking force is checked whether it has become smaller than a first predetermined value. If the braking force is greater than the first predetermined value, it indicates that a vehicle is being at rest on a sloping road. Before restarting the engine, a driver reduces the applied brake so that the braking force becomes smaller than the first predetermined value. If the braking force has become smaller than the first predetermined value, an auxiliary braking force is applied before the engine is restarted. Thus, the vehicle is prevented from moving backward when the engine is restarted.

9. An engine automatic-restart control method for a vehicle having an engine and a braking force operation member, the method comprising the steps of:
-
detecting an operation condition of the braking force operation member when the engine is held stopped;
applying automatically an auxiliary braking force to the vehicle when a detection result of the detecting step indicates a decrease in a braking force applied to the vehicle; and
restarting automatically the engine when the detection result of the detecting step indicates a release of the braking force operation member while maintaining the auxiliary braking force.
