Abstract

A vehicle control apparatus includes: a VSA-ECU and an ESB-ECU that perform braking control to apply a braking torque in response to a brake operation by a driver of a host vehicle, and also perform brake holding control to hold the braking torque even when the brake operation is cancelled; and an engine control unit that performs idling stop control to stop driving of an engine that is a drive source of the host vehicle when a stop condition is satisfied, including that a vehicle speed of the host vehicle enters a predetermined low vehicle speed region, and also performs restart control to restart the engine when a predetermined restart condition is satisfied. The engine control unit prohibits execution of the idling stop control during execution of the brake holding control.

First claim

What is claimed is:

1. A vehicle control apparatus comprising:
a braking control unit that performs braking control to apply a braking torque in response to a brake operation by a driver of a host vehicle, wherein
the braking control unit also performs brake torque holding control to hold the braking torque even when the brake operation is cancelled by the driver; and
an engine control unit that performs idling stop control to stop driving of an engine when an engine stop condition is satisfied, the engine stop condition including a condition where a vehicle speed of the host vehicle is determined to be in a predetermined low vehicle speed region, wherein
the engine control unit also performs restart control to restart the engine when a predetermined restart condition is satisfied, wherein
the engine control unit does not perform the idling stop control when the brake torque holding control is being performed and the vehicle is determined to be in a predetermined low vehicle speed region, and wherein
the engine control unit also performs the idling stop control when the brake torque holding control is being performed and the vehicle is determined to be stopped.

2. The vehicle control apparatus according to claim 1 , wherein when the driver manually operates a brake torque holding operation member provided in the vehicle the brake torque holding control is activated.

3. The vehicle control apparatus according to claim 1 , wherein the engine control unit permits execution of the idling stop control when the host vehicle is set in a stop state.

4. The vehicle control apparatus according to claim 1 , wherein the engine control unit executes the idling stop control when a stop condition including a condition where the vehicle speed of the host vehicle enters the low vehicle speed range is satisfied, during non-execution of a brake holding control without a setting operation using the brake holding operation member, and continuously executes the idling stop control when the brake holding control is subsequently executed by the setting operation using the brake holding operation member during execution of the idling stop control and before the host vehicle is set in a stop state.

5. The vehicle control apparatus according to claim 4 , wherein the engine control unit permits the execution of the restart control even when the brake holding control is subsequently executed by a setting operation using the brake holding operation member during execution of the idling stop control and before the host vehicle is set in a stop state.

6. The vehicle control apparatus according to claim 1 , wherein the engine control unit excludes cancelation of the brake operation from the predetermined restart condition when the host vehicle is set in a stop state and during execution of the brake holding control.

7. A vehicle comprising the vehicle control apparatus according to claim 1 .

8. A vehicle comprising the vehicle control apparatus according to claim 2 .

9. A vehicle comprising the vehicle control apparatus according to claim 3 .

10. A vehicle comprising the vehicle control apparatus according to claim 4 .

11. A vehicle comprising the vehicle control apparatus according to claim 5 .

12. A vehicle comprising the vehicle control apparatus according to claim 6 .
