Abstract

A vehicle drive assist system comprises a camera for picking up an image of an area existing in an advancing direction of a vehicle; display means for displaying the image picked up by the camera; steering angle detecting means for detecting a steering angle for steering the vehicle; traveling path predicting means for predicting a traveling path of the vehicle on the basis of the steering angle detected by the steering angle detecting means; and drive assist means for overlaying on the display means drive assist information containing the vehicle predictive traveling path predicted by the traveling path predicting means and guide lines prolonged from the lines defining the width of the vehicle body on the image of the area existing in the vehicle advancing direction.

Claims

1. A vehicle parking assist device comprising:

a camera for picking up an image of an area existing in a vehicle;

display means for displaying the image picked up by the camera; and

drive assist means for switching drive assist information for parking overlaid on the image displayed by the display means between the drive assist information of a normal parking mode and that of a series parking mode.

2. The vehicle drive assist device according to claim 1, wherein the drive assist means selects the drive assist information of a series parking mode when the turning on of a winker lamp or a hazard lamp and the shifting of the transmission to the reverse gear mode are simultaneously performed.

3. The vehicle drive assist device according to claim 1, the vehicle drive assist device mounted in the vehicle having a navigation device,

wherein the drive assist means for judging whether a parking position in which the vehicle is to be parked is in a parking lot or on a road on the basis of the present position of the vehicle derived from the navigation device, and the drive assist means for selecting the drive assist information of the normal parking mode when the parking position is in the parking lot, the drive assist means for selecting the drive assist information of the series parking mode when the parking position is on the road.

4. The vehicle drive assist device according to claim 1, wherein the drive assist means for selecting the drive assist information of the normal parking mode or the series parking mode in accordance with a change of a steering angle for steering the vehicle.
