Abstract

The engine automatic start stop control apparatus that controls an engine to be automatically stopped or started in response to driving conditions of a vehicle, comprises: a clutch detector for detecting depression of a clutch pedal; an accelerator detector for detecting depression of an accelerator pedal; an automatic stop detector for detecting an automatic stop of the engine; a stop history checker for checking a history of stopping of the vehicle when the automatic stop detector detects the stop of the vehicle; and an automatic start device for terminating the automatic stop of the engine and starting the engine when the automatic stop detector detects the automatic stop, when the clutch detector detects the depression of the clutch pedal, when the stop history checker finds no stop history, and when the accelerator detector detects depression of the accelerator pedal.

Claims

1. An engine automatic start stop control apparatus that controls an engine to be automatically stopped or started in response to driving conditions of a vehicle, comprising:

a clutch detector for detecting depression of a clutch pedal;

an accelerator detector for detecting depression of an accelerator pedal;

an automatic stop detector for detecting an automatic stop of the engine;

a stop history checker for checking a history of stopping of the vehicle when the automatic stop detector detects the stop of the vehicle; and

an automatic start device for terminating the automatic stop of the engine and starting the engine when the automatic stop detector detects the automatic stop, when the clutch detector detects the depression of the clutch pedal, when the stop history checker finds no stop history, and when the accelerator detector detects depression of the accelerator pedal.

2. An engine automatic start stop control apparatus according to claim 1, wherein the automatic stop detector detects fuel supply cut when the vehicle decelerates, to detect the stop of the vehicle.
