摘要： PROBLEM TO BE SOLVED: To provide a method for correcting a reference point of a sensor capable of correcting the reference point of the yaw rate sensor by suitably avoiding influence of a change of an ambient temperature in a vehicle of a traveling state and the vehicle of a stopped state.
SOLUTION: When the vehicle of the traveling state is stopped and a prescribed time ΔTst passes in the stopped state of the vehicle, a yaw rate neutral point is corrected only one time. After the prescribed time ΔTst passes in the stopped state of the vehicle without becoming the traveling state, the yaw rate neutral point is not corrected.

摘要： PROBLEM TO BE SOLVED: To provide a control device for an electric power steering giving suitable steering feeling according to the operation state of a vehicle behavior control device to a driver. SOLUTION: Since determination of step S1 becomes No when an operation switch of VSA is turned OFF by a driver or when VSA is not operated by defect, EPS-ECU 21 makes a second gain G2 to 0 at step S2. Thereby, in the steering assist control, a value of a second steering reaction force base value Tab2 becomes 0 and a steering reaction force target value Trt is calculated only based on a first steering reaction force base value Tab1. Namely, even if behavior of the vehicle body is disturbed by non-operation of VSA and a yaw rate becomes large, relatively small steering reaction force according to a steering angle is given and the driver can perform driving according to the behavior of the vehicle and the road surface state.
