Abstract

A parking assist apparatus includes: a peripheral image generation portion that generates an overhead image of a periphery viewed from above based on a captured image of a periphery of a vehicle; and a display image generation portion that generates a display image by superimposing a host vehicle image displaying a host vehicle on one of left and right sides in the overhead image and superimposing a target frame displaying a target of a movement destination of the vehicle on the other of the left and right sides in the overhead image in an assist mode of a forward parking or a backward exit.

Claims

1. A parking assist apparatus comprising:

a peripheral image generation portion that generates an overhead image of a periphery viewed from a view point above a vehicle based on a captured image of a periphery of the vehicle; and

a display image generation portion that generates a first display image by superimposing a host vehicle image displaying the vehicle on one of left and right sides in the overhead image viewed from the view point and superimposing a target frame displaying a target of a movement destination of the vehicle on the other of the left and right sides in the overhead image viewed from the view point in an assist mode of a forward parking or a backward exit;

wherein the display image generation portion generates a second display image by superimposing a second target frame displaying the target of the movement destination of the vehicle in a captured image of a periphery of the vehicle and displays the first display image and the second display image on a display portion, positions of the first target frame and the second target frame in the real world being at the same position.

2. The parking assist apparatus according to claim 1,

wherein the display image generation portion superimposes the host vehicle image on a rear side in the overhead image in the assist mode of the forward parking and superimposes the host vehicle image on a front side in the overhead image in the assist mode of the backward exit.

3. The parking assist apparatus according to claim 1,

wherein the display image generation portion superimposes both the target frame on a left side in the overhead image and the host vehicle image on a right side in the overhead image in a case of the assist mode for assisting the forward parking or the backward exit with respect to the target frame on a left side of the vehicle and superimposes both the target frame on a right side in the overhead image and the host vehicle image on a left side in the overhead image in a case of the assist mode for assisting the forward parking or the backward exit with respect to the target frame on a right side of the vehicle.

4. The parking assist apparatus according to claim 1,

wherein the display image generation portion superimposes the target frame on a preset set path in which the host vehicle image is set as a starting point.

5. The parking assist apparatus according to claim 3,

wherein the display image generation portion superimposes both the target frame on one of left and right sides in the overhead image and the host vehicle image on a center in the overhead image in a case of the assist mode for assisting the back parking.
