Abstract
The driving assistance device controls lateral movement of the vehicle. The driving assistance device includes a steering operation actuator that steers the wheels, a detection device that detects the position of the driver's hand touching the steering wheel, and an electronic control unit that controls the lateral direction of the vehicle. In lateral control, the electronic control unit controls the steering operation actuator so that the vehicle laterally moves to the right when a hand touches the right portion of the steering wheel, and when the hand touches the left portion of the steering wheel. In this case, the steering operation actuator is controlled so that the vehicle laterally moves to the left.
Claims6
A driving assistance device configured to control lateral movement of a vehicle, the driving assistance device comprising:
- a steering operation actuator configured to turn wheels of the vehicle;
- a detection device configured to detect a touching position of a hand of a driver touching a steering wheel;
- and
- an electronic control unit configured to execute lateral control on the vehicle, wherein
- the electronic control unit is configured to:
- determine whether the hand touches a right portion of the steering wheel or a left portion of the steering wheel based on the detected touching position;
- control the steering operation actuator to cause the vehicle to laterally move to right within a lane in which the vehicle is traveling, in a case where determination is made that the hand touches the right portion of the steering wheel;
- and
- control the steering operation actuator to cause the vehicle to laterally move to left within the lane in which the vehicle is traveling, in a case where determination is made that the hand touches the left portion of the steering wheel,
- the right portion is located on a right side with respect to a center line of the steering wheel, the center line being parallel to a vertical direction of the steering wheel, when the steering wheel is viewed alone from a front,
- the right portion includes an upper right portion, a middle right portion, and a lower right portion along a rotation direction of the steering wheel,
- the left portion is located on a left side with respect to the center line when the steering wheel is viewed alone from the front,
- the left portion includes an upper left portion, a middle left portion, and a lower left portion along a direction opposite to the rotation direction,
- the middle right portion and the middle left portion are dead zones in which the lateral control is not executed by the electronic control unit, and
- the electronic control unit is further configured to:
- determine whether the hand touches the middle right portion or the middle left portion based on the detected touching position;
- and
- not to execute the lateral control, in a case where determination is made that the hand touches the middle right portion and the middle left portion.
