Abstract:
A system for controlling steering of a vehicle, including:an actuator which steers driven wheels of the vehicle;1st assist torque calculating means for calculating a first assist torque for causing the vehicle to run along a reference line of a road existing ahead of the vehicle;steering torque detecting means for detecting a steering torque inputted by a vehicle driver of the vehicle;2nd assist torque calculating means for calculating a 2nd assist torque for assisting vehicle driver's steering of the vehicle in accordance with a predetermined characteristic based on the detected steering torque;manipulated variable calculating means for calculating a manipulated variable to be supplied to the actuator based on the calculated 1st and 2nd assist torques; andassist torque correcting means for correcting the calculated 1st and 2nd assist torques based on at least the detected steering torque; and whereinthe manipulated variable calculating means for calculating a manipulated variable to be supplied to the actuator based on the corrected 1st and 2nd assist torques.
