Abstract
Official abstract text for this publication.
An idle reduction control device mounted on a vehicle equipped with an engine and a brake including: a detector that detects a parameter having a positive correlation to an amount of brake operation; and an engine controller that controls a start and a stop of the engine. The engine controller stops the engine after a stop of the vehicle, when a change of the parameter caused by a release of the brake is equal to or greater than a predetermined value during a deceleration period before the stop of the vehicle.
First claim
Opening claim text (preview).
The invention claimed is: 1. An idle reduction control device mounted on a vehicle equipped with an engine and a brake, comprising: a detector that detects a parameter having a positive correlation to an amount of brake operation; and an engine controller that controls a start and a stop of the engine, wherein the engine controller stops the engine after a stop of the vehicle, when a reduction of the parameter caused by a release of the brake is equal to or greater than a predetermined value during a deceleration period before the stop of the vehicle, and wherein the engine controller prohibits the engine from being stopped after the stop of the vehicle and eliminates the prohibition after elapse of a predetermined time, when the reduction of the parameter is less than the predetermined value during the deceleration period. 2. The idle reduction control device according to claim 1 , wherein the parameter is a brake hydraulic pressure, and the engine controller stops the engine after the stop of the vehicle, when a reduction of the brake hydraulic pressure caused by the release of the brake is equal to or greater than a predetermined value, during the deceleration period. 3. The idle reduction control device according to claim 2 , wherein the engine controller stops the engine after the stop of the vehicle, when a difference between a brake hydraulic pressure detected by the detector and a maximum value of brake hydraulic pressures detected prior to the detected brake hydraulic pressure during the deceleration period is equal to or greater than a predetermined value. 4. An idle reduction control device mounted on a vehicle equipped with an engine and a brake, comprising: a detector that detects a brake hydraulic pressure having a positive correlation to an amount of brake operation; and an engine controller that controls a start and a stop of the engine, wherein the engine controller stops the engine after a stop of the vehicle, when a maximum value of the brake hydraulic pressure caused by the brake operation is equal to or less than a predetermined value during a deceleration period before the stop of the vehicle, and wherein the engine controller prohibits the engine from being stopped after the stop of the vehicle and eliminates the prohibition after elapse of a predetermined time when the maximum value of the brake hydraulic pressure is greater than the predetermined value during the deceleration period. 5. An idle reduction control device mounted on a vehicle equipped with an engine and a brake, comprising: a detector that detects a brake hydraulic pressure having a positive correlation to an amount of brake operation; and an engine controller that controls a start and a stop of the engine, wherein the engine controller stops the engine after a stop of the vehicle, when a maximum value of the brake hydraulic pressure caused by the brake operation is equal to or less than a predetermined value in a state where a vehicle speed of the vehicle decreases below a specified value during a deceleration period before the stop of the vehicle, and where the engine controller prohibits the engine from being stopped after the stop of the vehicle and eliminate the prohibition after elapse of a predetermined time, when the maximum value of the brake hydraulic pressure is greater than the predetermined value in the state where that the vehicle speed of the vehicle decreases below the specified value during the deceleration period. 6. A vehicle equipped with an engine and a brake, comprising: a detector that detects a parameter having a positive correlation to an amount of brake operation; and an engine controller that controls a start and a stop of the engine, wherein the engine controller stops the engine after a stop of the vehicle, when a reduction of the parameter caused by a release of the brake is equal to or greater than a predetermined value during a deceleration period before the stop of the vehicle, and wherein the engine controller prohibits the engine from being stopped after the stop of the vehicle and eliminates the prohibition after elapse of a predetermined time, when the reduction of the parameter is less than the predetermined value during the deceleration period. 7. A vehicle control method of controlling a vehicle equipped with an engine and a brake, comprising: (a) detecting a parameter having a positive correlation to an amount of brake operation; and (b) stopping the engine after a stop of the vehicle, when a reduction of the parameter caused by a release of the brake is equal to or greater than a predetermined value during a deceleration period before the stop of the vehicle, or prohibiting the engine from being stopped after the stop of the vehicle and eliminating the prohibition after elapse of a predetermined time, when the reduction of the parameter is less than the predetermined value during the deceleration period.
