Abstract
A control apparatus is applied to a vehicle including (i) a rotating electrical machine and (ii) a wheel speed sensor detecting a wheel speed. The control apparatus sets a rotation angle of the rotating electrical machine based on an estimated value of the rotation angle which is estimated based on a detection value of the wheel speed sensor.
Claims11
A control apparatus applied to a vehicle including (i) a rotating electrical machine functioning as a vehicle traveling drive source and (ii) a wheel speed sensor detecting a wheel speed, the rotating electrical machine including (i) a slotless stator containing a stator winding without slots by magnetic teeth, and (ii) a rotor containing a magnet unit,
- the control apparatus comprising:
- a setting circuit configured to set a rotation angle of the rotating electrical machine based on an estimated value of the rotation angle which is estimated based on a detection value of the wheel speed sensor;
- and
- a drive controller configured to control a drive of the rotating electrical machine based on the rotation angle set by the setting circuit.
A vehicle drive system applied to a vehicle including a wheel speed sensor to detect a wheel speed,
- the vehicle drive system comprising:
- a rotating electrical machine including (i) a slotless stator having a stator winding and not having slots formed by magnetic teeth, and (ii) a rotor having a magnet unit;
- and
- a control apparatus including
- (i) an electronic control circuit configured to set a rotation angle of the rotating electrical machine based on an estimated value of the rotation angle which is estimated based on a detection value of the wheel speed sensor;
