摘要： A vehicle steering control apparatus includes a power-supply supply portion 101 supplying a power supply to a micro-controller 102, an inverter 104 supplying power to drive a motor 5, a gate driver 103 controlling the inverter 104, a motor relay 105 opening and closing a current-passing path between the inverter 104 and the motor 5, a motor relay driver 106 controlling the motor relay 105, and a monitoring control portion A 108a and a monitoring control portion B 108b monitoring a power-supply voltage of the power-supply supply portion 101. Because multiple monitoring control portions are included, even in the event of an inconvenience in either one of the monitoring control portions A 108a and B 108b, the motor 5 can be stopped quickly in a reliable manner when the power-supply voltage goes out of a normal operation range.

摘要： An angle detecting apparatus is obtained. The angle detecting apparatus is capable of correcting an electrical angle frequency component of an angle signal contained angle signal. An angle detecting apparatus computes an angle signal of a rotary machine from a sine signal and a cosine signal obtained from the angle signal. Offset correction values for the sine signal and the cosine signal are computed from the angle signal. The computed offset correction value for the sine signal is added to the sine signal to correct the sine signal, and the computed offset correction value for the cosine signal is added to the cosine signal to correct the cosine signal.

摘要： An automatic steering apparatus that can suppress steering wheel vibration and that can also smooth angular control. In the automatic steering apparatus, a motor that steers steered wheels is controlled by a control unit. Information from an angle sensor that generates a signal that corresponds to a steering angle of the steered wheels is sent to the control unit. The control unit corrects a target steering angle of the steered wheels such that angular acceleration of the target steering angle is less than or equal to a limiting value. The control unit controls the motor such that the steering angle of the steered wheels tracks the corrected target steering angle based on the information from the angle sensor.
