1. A parking assist system, comprising:
- imaging units capturing images around a vehicle on which the parking assist system is mounted;
an overhead image generating unit generating an overhead image viewed down from above the vehicle by joining the images captured by the imaging units; and
a display unit displaying the generated overhead image, a parking frame figure corresponding to a target parking position as a parking target of the vehicle, and a backward parking start frame figure corresponding to a recommended backward parking start position for switching a direction of motion of the vehicle from forward to backward and starting backward movement to the target parking position for parking the vehicle,wherein position of the backward parking start frame figure on the overhead image changes corresponding to change in a steering angle of the vehicle.

Abstract
Upon a driver of a vehicle setting a target parking position, a parking assist system calculates a recommended parking start position which the vehicle can reach with a current steering angle of the vehicle unchanged and from which the vehicle can reach the parking target position with a constant steering angle. The parking assist system then draws a parking start frame figure F2 indicating a recommended parking start position on an overhead image around the vehicle generated using images captured by onboard cameras and displays the same on the display unit. It is therefore possible to properly assist the driving operation for parking allow inexperienced drivers to easily perform parking.

9. A parking assist method, comprising:
-
capturing images around a vehicle and generating an overhead image viewed down from above the vehicle by joining the captured images; displaying the generated overhead image, a parking frame figure corresponding to a target parking position as a parking target of the vehicle, and a backward parking start frame figure corresponding to a recommended backward parking start position for switching a direction of motion of the vehicle from forward to backward and starting backward movement to the target parking position for parking the vehicle; and changing position of the backward parking start frame figure on the overhead image corresponding to change in a steering angle of the vehicle.
