Abstract: A limit range setting section sets a primary limit range from a primary lower limit phase to a primary upper limit phase within an interval from a minimum torque phase to a maximum torque phase in a voltage phase-torque map. The limit range setting section calculates a phase obtained by adding a maximum amount of offset error of a rotation angle sensor to a zero phase as a secondary upper limit phase, and calculates a phase obtained by subtracting the maximum amount of offset error from the zero phase as a secondary lower limit phase. The limit range setting section sets a range from the primary lower limit phase to the secondary upper limit phase when a command torque is negative, and a range from the secondary lower limit phase to the primary upper limit phase when the command torque is positive as a secondary limit range.

Abstract: A first controller includes a start control section and a passage determination section. After activating a second starter to start cranking, the start control section stops the operation of the second starter and starts the motor operation of the first starter at a predetermined timing. The passage determination section determines whether a predetermined passage conditional expression holds after cranking is started by the second starter. The start control section stops the operation of the second starter and starts the motor operation of the first starter if the passage conditional expression holds before the engine passes the first compression top dead center, regardless of whether the engine has passed the first compression top dead center.
