1. A driving assist system for a vehicle, comprising:
- a driving state recognition device configured to detect a vehicle condition and a traveling environment of a subject vehicle;
a risk potential calculation device configured to calculate risk potential associated with the subject vehicle based on the detected vehicle condition and the detected traveling environment;
a reaction force control device configured to control an operation reaction force applied to a vehicle operating unit, based on the calculated risk potential;
an operating state detection device configured to detect an operating state of the vehicle operating unit operated by a driver to control the subject vehicle, wherein the operating state of the vehicle operating unit includes an operating direction of the vehicle operating unit; and
a reaction force correction device configured to correct the operation reaction force applied to the vehicle operating unit, based on the operating state of the vehicle operating unit.

Abstract
A vehicle driving assist system of the present invention detects a vehicle condition and a traveling environment of a subject vehicle; and calculates risk potential around the subject vehicle. The vehicle driving assist system calculates operation reaction force based on the risk potential around the subject vehicle, and corrects it according to operating state of an accelerator pedal. The corrected operation reaction force is generated in the accelerator pedal.
