AUXILIARY STEERING ANGLE CONTROL DEVICE FOR VEHICLE

摘要

PURPOSE:To suppress the sense of incompatibility to a driver and prevent the effect on other systems using the same power source when the power voltage drops by providing an auxiliary steering angle control device for a vehicle driving an electric steering angle actuator with the auxiliary steering angle feedback action quantity in response to the difference between the target value and the detected value of the motion state quantity. CONSTITUTION:This auxiliary steering angle control device for a vehicle is provided with a power voltage state detecting means (f) detecting the power voltage state of an electric steering angle actuator (e) electrically applying the auxiliary steering angle and an auxiliary steering angle feedback action quantity correcting means (g) monitoring the power voltage and reducing the auxiliary steering feedback action quantity when the power feeding capability of a power source is judged to be lacking.
