US Patent 7970535 Drive assist system

When moving a vehicle forward to park, a swept path during a period of parking operation is stored in memory. The vehicle is parked as forward parking, in which the front of the vehicle faces the dead end of a parking space of a side-by-side parking lot. In starting the vehicle from the parking space, an assist start switch is turned on to thereby cause a control unit to compute a rearward exit method to move the vehicle rearward to thereby exit from the parking space by referring to surrounding information on surroundings of the vehicle and the stored swept path. A display device is then caused to display the computed rearward exit method to notify a driver of the vehicle.
