Abstract

Lane keeping control is ended in accurate timing which does not give an uncomfortable feeling to a driver. In a vehicle 10 which is provided with a steering mechanism 200, an EPS actuator 300, and a VGRS actuator 500 and which can change a rudder angle regardless of a driver'"'"'s steering input due to the cooperative control of the aforementioned mechanism and actuators, an ECU 100 performs LKA end control. In the control, in cases where a winker lever 16 is operated in a period of performing LKA control for making the vehicle 10 follow a target driving route, if the indicated direction of the winker lever 16 is different from a generation direction of generating an assist steering torque TA of the EPS actuator 300 in the LKA control, the LKA control is promptly ended. In cases where the indicated direction is equal to the generation direction, if a steering angle MAdrv corresponding to the driver'"'"'s steering input exceeds a steering angle MAlka generated by the LKA control, the LKA control is ended.

Claims

1. A control apparatus for a vehicle, comprising:

a directional indicator configured to detect a driving direction indicated by a driver; and

a controller configured to generate an assist torque in a generation direction to perform a lane keeping control such that the vehicle follows a target driving route;

wherein the controller stops the lane keeping control in response to detecting that the generation direction is different than the indicated direction, and continues the lane keeping control in response to detecting that the generation direction is the same as the indicated direction.

2. The control apparatus for the vehicle according to claim 1, further comprising a detecting device configured to detect the direction of the assist torque.

3. The control apparatus for the vehicle according to claim 1,

wherein the controller stops and continues the lane keeping control in response to a detection that the lane keeping control is activated.

4. The control apparatus for the vehicle according to claim 3,

wherein the controller stops the assist torque when the generation direction is different than the indicated direction, and continues the assist torque when the generation direction is the same as the indicated direction.

5. A control apparatus for a vehicle, comprising:

a directional indicator configured to detect a driving direction indicated by a driver, and

a controller configured to generate an assist torque in a generation direction to perform a lane keeping control such that the vehicle follows a target driving route;

wherein the controller includes circuitry which stops the lane keeping control in response to detecting that the generation direction is different than the indicated direction, and continues the lane keeping control in response to detecting that the generation direction is the same as the indicated direction.

6. The control apparatus for the vehicle according to claim 5, further comprising a detecting device configured to detect the direction of the assist torque.

7. The control apparatus for the vehicle according to claim 5,

wherein the controller stops and continues the lane keeping control in response to a detection that the lane keeping control is activated.

8. The control apparatus for the vehicle according to claim 7,

wherein the controller stops the assist torque when the generation direction is different than the indicated direction, and continues the assist torque when the generation direction is the same as the indicated direction.

9. A control apparatus for a vehicle, comprising:

means for detecting a driving direction indicated by a driver; and

control means for generating an assist torque in a generation direction to perform a lane keeping control such that the vehicle follows a target driving route;

wherein the control means stops the lane keeping control in response to detecting that the generation direction is different than the indicated direction, and continues the lane keeping control in response to detecting that the generation direction is the same as the indicated direction.

10. The control apparatus for the vehicle according to claim 9, further comprising a means for detecting a direction of the assist torque.

11. The control apparatus for the vehicle according to claim 9,

wherein the control means stops and continues the lane keeping control in response to a detection that the lane keeping control is activated.

12. The control apparatus for the vehicle according to claim 11,

wherein the control means stops the assist torque when the generation direction is different than the indicated direction, and continues the assist torque when the generation direction is the same as the indicated direction.

13. A vehicle control method, comprising:

detecting a driving direction indicated by a driver by a directional indicator;

generating an assist torque to perform a lane keeping control such that the vehicle follows a target driving route;

stopping the lane keeping control in response to detecting that the indicated direction is not the same as the direction of the assist torque; and

continuing the lane keeping control in response to detecting that the indicated direction is the same as the direction of the assist torque.
