Abstract

A vehicle control device configured to be capable of executing idle stop control to automatically stop an engine when a predetermined automatic stop condition is satisfied and restart the engine when a predetermined restart condition is satisfied during the automatic stop of the engine, the vehicle control device includes: a start request detector, a shift position detector, and a delay time setting module. A start request detector detects a driver operation indicating a request for starting the engine by a driver. A shift position detector detects a shift position of a shift changer. A delay time setting module sets, on a basis of presence or absence of the driver operation and the shift position, a delay time from when the engine is restarted until when an automatic stop of the engine is permitted.

First claim

1 . A vehicle control device capable of executing idle stop control to automatically stop an engine when a predetermined automatic stop condition is satisfied and restart the engine when a predetermined restart condition is satisfied during the automatic stop of the engine, the vehicle control device comprising:
a start request detector configured to detect a driver operation indicating a request for starting the engine by a driver; a shift position detector configured to detect a shift position of a shift changer; and a delay time setting module configured to set, on a basis of presence or absence of the driver operation and the shift position, a delay time from when the engine is restarted until when an automatic stop of the engine is permitted.

2 . The vehicle control device according to claim 1 , wherein the delay time setting module varies a length of the delay time according to the shift position when a restart of the engine is not due to the driver operation.

3 . The vehicle control device according to claim 2 , wherein the delay time setting module sets the delay time to be shorter when the shift position is in a travel range than when the shift position is in a non-travel range.

4 . The vehicle control device according to claim 2 , wherein that the restart of the engine is not due to the driver operation means that a restart is due to an operation condition of an on-board air conditioner.

5 . The vehicle control device according to claim 3 , wherein that the restart of the engine is not due to the driver operation means that a restart is due to an operation condition of an on-board air conditioner.

6 . The vehicle control device according to claim 1 , wherein the delay time setting module sets the delay time to zero when a restart of the engine is due to the driver operation.

7 . The vehicle control device according to claim 2 , wherein the delay time setting module sets the delay time to zero when a restart of the engine is due to the driver operation.

8 . The vehicle control device according to claim 3 , wherein the delay time setting module sets the delay time to zero when a restart of the engine is due to the driver operation.

9 . The vehicle control device according to claim 4 , wherein the delay time setting module sets the delay time to zero when a restart of the engine is due to the driver operation.

10 . The vehicle control device according to claim 5 , wherein the delay time setting module sets the delay time to zero when a restart of the engine is due to the driver operation.

11 . The vehicle control device according to claim 1 , wherein the driver operation comprises at least an operation of depressing an accelerator pedal or an operation of releasing a depressed brake pedal.

12 . The vehicle control device according to claim 2 , wherein the driver operation comprises at least an operation of depressing an accelerator pedal or an operation of releasing a depressed brake pedal.

13 . The vehicle control device according to claim 3 , wherein the driver operation comprises at least an operation of depressing an accelerator pedal or an operation of releasing a depressed brake pedal.

14 . The vehicle control device according to claim 4 , wherein the driver operation comprises at least an operation of depressing an accelerator pedal or an operation of releasing a depressed brake pedal.

15 . The vehicle control device according to claim 5 , wherein the driver operation comprises at least an operation of depressing an accelerator pedal or an operation of releasing a depressed brake pedal.

16 . A vehicle control device capable of executing idle stop control to automatically stop an engine when a predetermined automatic stop condition is satisfied and restart the engine when a predetermined restart condition is satisfied during the automatic stop of the engine, the vehicle control device comprising:
a start request detector configured to detect a driver operation indicating a request for starting the engine by a driver; and a delay time setting module configured to set a delay time from when the engine is restarted until when an automatic stop of the engine is permitted, wherein the delay time setting module sets the delay time to zero when a restart of the engine is due to the driver operation.

17 . A vehicle control device capable of executing idle stop control to automatically stop an engine when a predetermined automatic stop condition is satisfied and restart the engine when a predetermined restart condition is satisfied during the automatic stop of the engine, the vehicle control device comprising:
circuitry configured to detect a driver operation indicating a request for starting the engine by a driver, detect a shift position of a shift changer and set, on a basis of presence or absence of the driver operation and the shift position, a delay time from when the engine is restarted until when an automatic stop of the engine is permitted.
