Driving assist system for vehicle
First Claim
1. A driving assist system for vehicle comprising:
- a state recognition device that detects vehicle conditions of a subject vehicle and a traveling environment for vehicle surroundings;
a risk potential calculator that calculates a risk potential for vehicle surroundings based on detection results of the state recognition device;
a risk change estimator that estimates a change in risk felt by a driver;
a correction device that corrects a calculation equation for calculating the risk potential at the risk potential calculator based on estimation results of the risk change estimator; and
an operation reaction force controller that modifies a reaction force applied to vehicle operation equipment based on the risk potential calculated using the calculation equation corrected by the correction device, to convey information related to the risk potential to the driver via the vehicle operation equipment;
wherein the vehicle operation equipment is used by the driver in operating the vehicle.
