Abstract:
1. A vehicle driving assist system comprising: a preceding object detecting section configured to detect a preceding object existing in front of a host vehicle; a risk potential calculating section configured to calculate a risk potential indicative of a degree of convergence between the host vehicle and the preceding object based on a detection result of the preceding object detecting section; a first driving assistance control system configured to control at least one of an actuation reaction force exerted by a driver-operated driving operation device and a braking/driving force exerted against the host vehicle based on the risk potential calculated by the risk potential calculating section; a second driving assistance control system configured to control the braking/driving force of the host vehicle such that a headway distance is maintained between the host vehicle and the preceding object; a transition detecting section configured to detect a transition of operating states between the first and second driving assistance control systems; and a control adjusting section configured to adjust a target rate of at least one of the braking/driving force and the actuation reaction force during transition between the first and second driving assistance control systems to correspond to a modified target rate that is different from the target rate of the at least one of the braking/driving force and the actuation reaction force used during the first and second driving assistance control systems.
