Patent ID: 7734419

Claim:
A vehicle driving assist system comprising: an obstacle detecting section configured to detect a preceding obstacle existing in front of a host vehicle and selectively output an obstacle detection result; a risk potential calculating section configured to calculate a risk potential indicative of a degree of risk potential of the host vehicle with respect to the preceding obstacle based on the obstacle detection result of the obstacle detecting section; a haptic information conveying section configured to convey the risk potential calculated by the risk potential calculating section to a driver as haptic information through a driver-operated driving operation device; and a visual information conveying section configured to convey visual information of the preceding obstacle to the driver that is targeted as a targeted obstacle based on the risk potential calculated by the risk potential calculating section, and to convey the degree of the risk potential with respect to the targeted obstacle as calculated by the risk potential calculating section, the visual information conveying section being further configured to overlay the targeted obstacle with a risk potential marker indicating the degree of the risk potential as calculated by the risk potential calculating section.
