Abstract:
1. A vehicle driving assist system comprising: a traveling situation detecting section configured to output a traveling situation detection result based on at least a following distance between a host vehicle and a preceding obstacle and a host vehicle speed of the host vehicle; a controller having a processor including a risk potential calculating section configured to calculate a risk potential indicative of a degree of convergence between the host vehicle and the preceding obstacle based on the traveling situation detection result of the traveling situation detecting section; a driving assist control section configured to control, based on the risk potential calculated by the risk potential calculating section, at least one of an actuation reaction force of a driver-operated driving device of the host vehicle that counteracts an operation force to operate the driver-operated driving device and a braking/driving force exerted against the host vehicle; a failure detecting section configured to detect a failure of an operating condition of at least part of the vehicle driving assist system; and a failsafe control section configured to perform a failsafe control operation that changes control by the driving assist control section to suppress changes in acceleration or deceleration caused by the failure of the operating condition when the failure of the operating condition has been detected in the vehicle driving assist system.
