Engine automatic stop restart control apparatus, vehicle equipped with engine automatic stop restart control apparatus, and engine automatic stop restart method
First Claim
1. An engine automatic stop restart-control apparatus mounted on a motor vehicle, said engine automatic stop restart control apparatus performing automatic engine stop control to automatically stop an engine in response to a driver'"'"'s depression of brake as one of preset engine stop conditions and performing automatic engine restart control to automatically restart the engine in response to the driver'"'"'s release of brake as one of preset engine restart conditions, said engine automatic stop restart control apparatus comprising:
- an automatic drive control module that performs vehicle automatic stop control to automatically stop the motor vehicle upon satisfaction of predetermined vehicle stop conditions;
an engine stop condition judgment module that determines whether all the preset engine stop conditions except the driver'"'"'s depression of brake are satisfied after an automatic stop of the motor vehicle by the vehicle automatic stop control of said automatic drive control module; and
an engine stop control module that performs the engine automatic stop control to automatically stop the engine when said engine stop condition judgment module determines satisfaction of all the preset engine stop conditions except the driver'"'"'s depression of brake.

Abstract
In a vehicle having idle stop functions and low vehicle speed-following drive functions, when a vehicle automatic stop flag F2 is identified as 1 at step S220, determines whether all engine stop conditions except depression of brake pedal are satisfied in step S240. When it is determined all the engine stop conditions except depression of the brake pedal are satisfied, ignition and fuel injection in each cylinder of engine are stopped to automatically stop the engine in step S260. In this arrangement, the driver'"'"'s depression of brake is excluded from the engine stop conditions. Therefore, even when the motor vehicle automatically stops without the driver'"'"'s depression of brake, the engine is automatically stopped.
