## Abstract

A vehicle controlling device includes: a VSA-ECU that performs deceleration control of a host vehicle using an inter-vehicle distance between the host vehicle and another vehicle traveling in front of the host vehicle; and an engine control unit that performs idling stop control of stopping drive of an engine as a driving source of the host vehicle upon satisfying stop conditions including a condition that vehicle speed of the host vehicle enters a predetermined low vehicle speed range and performs restart control of restarting the engine upon satisfying a predetermined restart condition. A power supply mounted on the host vehicle is used in common as a power supply used in executing the deceleration control and a power supply used in executing the restart control. The engine control unit prohibits execution of the idling stop control during execution of the deceleration control.

## Claims

### Claim 1

A vehicle controlling device comprising:
a deceleration controller that performs deceleration control of a host vehicle using an inter-vehicle distance between the host vehicle and another vehicle traveling in front of the host vehicle; and
an engine controller that performs idling stop control of stopping drive of an engine as a driving source of the host vehicle upon satisfying stop conditions including a condition that vehicle speed of the host vehicle enters a predetermined low vehicle speed range and performs restart control of restarting the engine upon satisfying a predetermined restart condition, wherein
a power supply mounted on the host vehicle is used for executing the deceleration control and the restart control,
the engine controller prohibits execution of the idling stop control during execution of the deceleration control,
the deceleration controller performs the deceleration control of the host vehicle using a difference between a preset demanded inter-vehicle distance and an actual inter-vehicle distance between the host vehicle and another vehicle traveling in front of the host vehicle,
the engine controller further performs acceleration control of the host vehicle using the difference between the demanded inter-vehicle distance and the actual inter-vehicle distance, and
the engine controller prohibits execution of the idling stop control during execution of following control including the deceleration control and the acceleration control.

### Claim 2 (depends on 1)

The vehicle controlling device according to claim 1, wherein the engine controller permits execution of the idling stop control when the host vehicle is in a stopped state.

### Claim 3 (depends on 1)

A vehicle comprising the vehicle controlling device according to claim 1.

### Claim 4 (depends on 2)

A vehicle comprising the vehicle controlling device according to claim 2.
