Abstract:
1. A vehicle drive assist system comprising: a displaying means for displaying supplied image information on or through a front glass of a vehicle; an information obtaining means for obtaining lane information that indicates a configuration and a position of a traveling lane, along which the vehicle travels; a view point sensing means for sensing a view point position of a driver of the vehicle; an image information generating means for generating and supplying the image information to the displaying means, wherein the image information indicates at least one lane guide of the traveling lane, which corresponds to the configuration of the traveling lane that is viewed from the sensed view point position of the driver through the front glass, and the image information generating means generates the image information though computation based on the sensed view point position of the driver, which is sensed by the view point sensing means, and the lane information, which is obtained by the information obtaining means; a background color sensing means for sensing a color of a road surface, which is located ahead of the vehicle; and a display color adjusting means for setting a display color of the at least one lane guide displayed by the displaying means to a color, which is distinguishable from the sensed color of the road surface that is sensed by the background color sensing means, wherein the lane information is constructed to include obstacle information, which indicates presence of an obstacle along at least one of two opposed side edges of the traveling lane; and when the image information, which indicates the at least one lane guide, is computed by the image information generating means based on the lane information, which includes the obstacle information indicating the presence of the obstacle, the display color adjusting means sets the display color of the at least one lane guide to a predetermined warning color.
