发明名称 Resolver signal processing method and processing apparatus
摘要 The electrically-powered steering apparatus obtains a steering torque and a steering angle within an allowable input range of those inputted into a first resolver and a second resolver based on a real zero point alpha and further, a steering torque and a steering angle out of the allowable input range of those inputted to the first resolver and the second resolver based on (+) virtual zero point beta and (-) virtual zero point gamma, which are set to a different value from the real zero point alpha. Consequently, of the steering torques and steering angles inputted to the first resolver and the second resolver, the steering torque and steering angle out of the allowable input range impossible to obtain by the real zero point alpha can be obtained based on the (+) virtual zero point beta and the (-) virtual zero point gamma.
