  • Publication number: 20190375381
    Abstract: A parking support device 10 comprises a display device 70 and a control device 20. When the control device determines a parking request operation is performed, the control device displays a parking area image 300. When the control device determines that a parking start condition, which is satisfied when the parking request operation is performed and the vehicle stops, has been satisfied, the control device starts a stop brake control required to cause the vehicle not to move. When the control device determines that a parking consent operation has been performed after the parking start condition became satisfied, the control device finishes the stop brake control and starts an automatic parking control for controlling a traveling state of the vehicle in order to park the vehicle into the parking area.
