  • Patent number: 11616466
    Abstract: A current sensor state determination device determines that an abnormality is caused in a current sensor when a sum of phase currents based on current detection values from each of the current sensors in three phases is greater than a first determination value, and determines that no abnormality is caused in the current sensor when the sum of phase currents is equal to or less than the first determination value. The state determination device determines that the current sensor is normal when it is determined that (i) no abnormality is caused in a preset electric angle range equal to or less than one electric-angle cycle of the rotating electric machine and (ii) a value of an electric current flowing in the rotating electric machine in a rotating coordinates system calculated based on the current detection value is equal to or greater than a second determination value.

  • Publication number: 20230093525
    Abstract: In the grommet, it is assumed that a point at a leading end position of the extension portion is a point A, and a point at a position furthest from the point A as seen in the insertion direction in a leading end region of the fitting portion in the insertion direction is a point B. It is assumed that a width of the through hole in a cross section that is parallel with the insertion direction and passes through the point A and the point B when the fitting portion is fitted to the through hole is a hole width W. At this time, a total of a linear distance L between the point A and the point B and a thickness T of the seal lip is larger than the hole width W.

  • Publication number: 20230079227
    Abstract: A first circuit energizes a steering assist actuator to electrically assist steering of a driver. A second circuit is provided in a same housing as the first circuit and energizes a positional actuator to move a steering position. A controller operates the first and second circuits to control operations of the steering assist actuator and the positional actuator. The controller changes a priority between the first circuit and the second circuit in a start period, in which the steering control device is started, a normal operation period, in which the steering control device is operated normally, and a stop period, in which the steering control device is stopped. The priority includes at least one of an order of operating the first circuit and the second circuit, output allocation between the first circuit and the second circuit, and output magnitude between the first circuit and the second circuit.
