Abstract

An electronic control unit performs driving force reduction control to reduce the driving force of a driving wheel of the vehicle. Then, if an accelerator pedal is operated after the lapse of a predetermined time since detection of an obstacle that may collide with a vehicle, the electronic control unit brakes the driving wheel as driving force reduction control.

Claims

1. A vehicular control apparatus that performs driving force reduction control to reduce a driving force of a driving wheel of a vehicle, the vehicular control apparatus comprising:

a controller that determines whether or not the driving force reduction control needs to be performed, on a basis of a time from detection of an obstacle that may collide with the vehicle by the controller, to an operation of an accelerator of the vehicle.

2. The vehicle control apparatus according to claim 1, wherein

an obstacle that approaches to the vehicle or to a travelling side of the vehicle is detected as the obstacle that may collide with the vehicle.

3. The vehicular control apparatus according to claim 1, wherein

the controller brakes the driving wheel as the driving force reduction control.

4. The vehicular control apparatus according to claim 1, wherein

the controller reduces an engine output of the vehicle as the driving force reduction control.

5. A vehicular control apparatus comprising:

a controller that performs driving force reduction control to reduce a driving force of a driving wheel of a vehicle, if a brake of the vehicle is not operated before lapse of a first predetermined time since detection of an obstacle that may collide with a vehicle by the controller, and an accelerator of the vehicle is operated after lapse of the first predetermined time since detection of the obstacle that may collide with the vehicle.

6. The vehicle control apparatus according to claim 5, wherein

an obstacle which approaches to a vehicle or to a travelling path of a vehicle is detected as the obstacle which may collide with the vehicle.

7. The vehicular control apparatus according to claim 5, wherein

the controller brakes the driving wheel as the driving force reduction control.

8. The vehicular control apparatus according to claim 5, wherein

the controller reduces an engine output of the vehicle as the driving force reduction control.

9. The vehicular control apparatus according to claim 5, wherein

the controller reduces an engine output of the vehicle, if the accelerator is operated before lapse of a second predetermined time that is earlier than the first predetermined time since detection of the obstacle that may collide with the vehicle.

10. A vehicular control method for performing driving force reduction control to reduce a driving force of a driving wheel of a vehicle, the vehicular control method, comprising:

determining whether or not the driving force reduction control needs to be performed, on a basis of a time from detection of an obstacle that may collide with the vehicle, to an operation of an accelerator of the vehicle.

11. The vehicle control method according to claim 10, wherein

an obstacle that approaches to the vehicle or to a travelling path of the vehicle is detected as the obstacle that may collide with the vehicle.

12. A vehicular control method comprising:

performing driving force reduction control to reduce a driving force of a driving wheel of a vehicle, if a brake of the vehicle is not operated before lapse of a first predetermined time since detection of an obstacle that may collide with a vehicle, and an accelerator of the vehicle is operated after lapse of the first predetermined time since detection of the obstacle that may collide with the vehicle.

13. The vehicle control method according to claim 12, wherein

an obstacle that approaches to the vehicle or to a travelling path of the vehicle is detected as the obstacle that may collide with the vehicle.
