  • Current-carrying control device and electric power steering apparatus
    Patent number: 6520279
    Abstract: Current correction control is carried out by control process of a control circuit 13 that temperatures of the electromagnetic relays 18a and 18b are assessed one by one based on the detection temperature by the temperature sensor 18c, when the temperature assessed value rises over the predetermined value, the upper limit of the target current value of the motor 11 is decreased.
    Type: Grant
