  • Patent number: 11529990
    Abstract: An ECU, which is a signal control apparatus, has a plurality of control units, which control one same motor. Steering angle calculation units acquire sensor signals from the angle sensors provided corresponding to the steering angle calculation units, respectively, and calculate the steering angles in correspondence to the sensor signals. The angle FB units perform the angle FB control based on the angle differences, which are between the target angle and the steering angle and between the target angle and the steering angle, respectively. In the angular FB unit of at least one of the control units, the angular feedback control is performed using the angle difference, which is subjected to the correction processing to reduce the error between the detection angle of the own system and the detection angle of the other system calculated by the steering angle calculation unit of the other control unit.

  • Patent number: 11479291
    Abstract: Each of a plurality of microcomputers outputs a motor drive signal, which is generated based on a current command value and a current limit value as a control amount command value and a control amount limit value, to each motor drive circuit. When an OFF determination of an own microcomputer is made, each microcomputer executes first end processing as a first stage of end processing and transmits an OFF determination signal to the other microcomputer. When the OFF determination signal is received from the other microcomputer, each microcomputer determines that the OFF determination has been made and starts second end processing which gradually decreases the current command value or the current control limit value from a present value. When the second end processing is completed and power-off preparation of the own microcomputer and the other microcomputer is completed, each microcomputer executes final end processing for turning off the power supply relay.

  • Patent number: 11472473
    Abstract: A motor control device is provided with a plurality of power converters and a plurality of microcomputers, and controls driving of a motor that has a plurality of sets of windings. The microcomputers perform initial check of components in respective circuits after activation. The microcomputers prohibit driving of the motor by a circuit determined to be abnormal during the initial inspection. When two or more circuits are determined to be normal in the initial check, the microcomputers start driving of the motor by synchronizing the timing between the two or more circuits determined to be normal. When only one circuit is determined to be normal in the initial check, the microcomputers start driving of the motor by the one circuit determined to be normal.

  • Patent number: 11465683
    Abstract: A steering angle detection device is provided with a plurality of rotation angle sensors and a plurality of control units. The rotation angle sensors are capable of at least continuously calculating a rotation speed while an ignition switch of a vehicle is turned off, and are provided so as to correspond to steering angle calculation units which calculate steering angle based on the rotation speed and a rotation angle acquired from the rotation angle sensors and midpoint information related to the neutral position of a steering member. Power supplies are provided on a per-system basis. The rotation angle sensors or the control units are capable of holding the midpoint information while the ignition switch is turned off. If a power supply abnormality resulting in power supply failure occurs in some of the systems, the control unit of the abnormal system acquires the midpoint information and the rotation speed from the control unit of a normal system when the ignition switch is turned on.
