Abstract

A vehicle can reverse immediately after setting a no idling state in accordance with a simple operational procedure. An idle reduction control unit set the engine into a no idling state if the key switch is on, the brake is operated, the vehicle speed is zero, and the shift position is in the drive range; and restarts the engine if the braking operation is released and the shift position is in the drive range when the engine is in the no idling state. The idle reduction control unit also restarts the engine if the shift position is shifted from the drive range to the neutral range while the brake is still being operated when the engine is in the no idling state.

First claim

The invention claimed is:

1. An idle reduction control device in which an engine is set to a no idling state when a key switch is in an ON state, a brake is operated, thus a vehicle speed is zero and a shift position is in a drive range, and the engine is restarted when an operation of the brake is released while the engine is in the no idling state and the shift position is in the drive range,
wherein the engine is restarted when the shift position is transferred from the drive range to a neutral range while the brake is still being operated when the engine is in the no idling state.

2. The idle reduction control device according to claim 1 , wherein prior to executing idle reduction in a vehicle having a hill start assisting device holding braking force even though a driver releases the operation of the brake when stopping on an ascending slope, when the hill start assisting device is in an off state, the hill start assisting device is forcibly turned on.

3. A vehicle having an idle reduction control device according to claim 1 , wherein
the idle reduction control device is started with the start of the vehicle, and
the vehicle has a switch that alternately repeats pause and restart of the idle reduction control device whenever the switch is operated.

4. The vehicle according to claim 3 , wherein, when the brake is operated at a strength of a predetermined value or more, a gear position is set to a neutral stage and provided in the idle reduction and when the brake is operated at a strength less than a predetermined value, the gear position is set to a start stage.

5. The vehicle of claim 3 , wherein, when an engine is set to the idle reduction, a rotational shaft of the engine is connected to a rotational shaft of an electric motor controlled to hold zero rotation.

6. The vehicle according to claim 3 , further comprising an engine and an electric motor,
wherein a hybrid vehicle is driven by an engine or an electric motor, or cooperation of the engine and the electric motor.

7. An idle reduction control method for an idle reduction control device in which an engine is set to a no idling state when a key switch is in an ON state, a brake is operated, thus a vehicle speed is zero and a shift position is in a drive range, and the engine is restarted when an operation of the brake is released while the engine is in the no idling state and the shift position is in the drive range, wherein the engine is restarted when the shift position is transferred from the drive range to a neutral range while the brake is still being operated when the engine is in the no idling state.

8. A computer program for causing an information processing device to execute a function of an idle reduction control device according to claim 1 .
