Abstract:
1. A vehicle operation assisting system that assists a collision avoidance operation which a driver performs to avoid collision with an obstacle during traveling, of a vehicle, comprising: a collision avoidance operation determining device that determines the collision avoidance operation by the driver: an obstacle detecting device that detects an obstacle with which an own vehicle has a possibility of colliding; an avoidance momentum calculating device that calculates avoidance momentum necessary for avoiding the obstacle detected by the obstacle detecting device when the collision avoidance operation determining device determines the collision avoidance operation by the driver; a target assist electrical current calculating device that calculates a target assist electrical current, which is supplied to a steering actuator, based on the avoidance momentum calculated by the avoidance momentum calculating device; an under-steer determining device that determines an under-steer state of the vehicle; and a reaction force electrical current calculating device that calculates a reaction force electrical current which decreases the target assist electrical current, when the under-steer state of the vehicle is determined by the under-steer determining device and the collision avoidance operation by the driver is determined by the collision avoidance operation determining device.
