Engine control apparatus

An engine control apparatus comprising:

• brake depression degree detecting means for detecting a degree of depression of a brake pedal in a vehicle;
• brake depression degree judging means for judging whether or not the detected degree of depression of the brake pedal is smaller than a first prescribed value;
• deceleration detecting means for detecting a deceleration of the vehicle;
• automatic engine stop and restart controlling means for automatically stopping an engine powering the vehicle when the deceleration detecting means detects a deceleration of the vehicle and the brake depression degree judging means judges that the detected degree of depression of the brake pedal is not smaller than the first prescribed value;
• and
• wherein the brake depression degree judging means operates for judging whether or not the detected degree of depression of the brake pedal is greater than a second prescribed value smaller than the first prescribed value, and the automatic engine stop and restart controlling means operates for restarting the engine when the brake depression degree judges that the detected degree of depression of the brake pedal is not greater than the second prescribed value.

• and
• brake depression speed detecting means for detecting a speed of depression of a brake pedal in the vehicle, and wherein the automatic engine stop and restart controlling means inhibits automatic stop of the engine when the speed detected by the brake depression speed detecting means is higher than a predetermined speed.

An engine control apparatus comprising:

• brake depression decree detecting means for detecting a decree of depression of a brake pedal in a vehicle;
• brake depression degree judging means for judging whether or not the detected degree of depression of the brake pedal is smaller than a first prescribed value;
• deceleration detecting means for detecting a deceleration of the vehicle;
• automatic engine stop and restart controlling means for automatically stopping an engine powering the vehicle when the deceleration detecting means detects a deceleration of the vehicle and the brake depression degree judging means judges that the detected degree of depression of the brake pedal is not smaller than the first prescribed value;
• and
• relative speed detecting means for detecting a relative speed between the vehicle and a preceding vehicle, and wherein the automatic engine stop and restart controlling means inhibits automatic stop of the engine when the relative speed detected by the relative speed detecting means is higher than a predetermined speed.
