A driving assist system for a vehicle comprises a traveling condition recognition device that detects a state of the vehicle and a traveling environment of the vehicle; a risk potential calculation device that calculates a risk potential present around the vehicle based upon detection results obtained by the traveling condition recognition device; a reaction force adjustment device that adjusts reaction force characteristics of a vehicle operating device based upon the risk potential calculated by the risk potential calculation device; an external influence detection device that detects an external influence which will affect an operation of the vehicle operating device by a driver; and a reaction force correction device that corrects the reaction force characteristics of the vehicle operating device adjusted by the reaction force adjustment device, based upon detection results obtained by the external influence detection device.
