Driving assistance device

A driving assistance device comprising

• an electronic control unit including a steering control unit that, in the case of changing a steering angle of a wheel of the vehicle from a first steering angle on one side of a neutral position to a second steering angle on another side of the neutral position when a state of the vehicle is switched from a first state to a second state, is configured to control the steering angle so as to cause the steering angle to start to be directed from the first steering angle toward the second steering angle before the state of the vehicle becomes the second state, and to control the steering angle so as to cause the steering angle to be directed from a third steering angle in between the first steering angle and the second steering angle toward the second steering angle when the state of the vehicle is the second state, the first state being one of an advancing state and a reversing state, the second state being another of the advancing state and the reversing state;
• and
• a detector that detects a distance between an obstacle in front of the vehicle in a stationary state and an obstacle in the rear of the vehicle,
• wherein the steering control unit is configured to control the steering angle so as to cause the steering angle to start to be directed from the first steering angle toward the second steering angle when the state of the vehicle is the first state when the distance is equal to or more than a threshold, and to control the steering angle so as to cause the steering angle to start to be directed from the first steering angle toward the second steering angle when the state of the vehicle is a stationary state midway through a process during which the first state is switched to the second state when the distance is less than the threshold.
