  • Publication number: 20200298839
    Abstract: A parking assistance device performs parking assistance control including steering angle control for changing a steering angle of a vehicle, driving force control for controlling a driving force of the vehicle, and braking force control for controlling a braking force of the vehicle. The parking assistance device notifies an occupant of a driving operation to be performed by the occupant, including a moving operation on a shift lever and an operation on a brake pedal when the vehicle reaches a switching position where a traveling direction of the vehicle is to be switched during performing the parking assistance control. When the driving operation is performed by the occupant, the parking assistance device restarts the parking assistance control at a timing when the occupant stops the operation on the brake pedal.
