CPC H02P 27/06 (2013.01) [B60L 3/0061 (2013.01); B60L 15/20 (2013.01); H02P 29/024 (2013.01)] | 12 Claims |
1. A control device for a rotating electrical machine, the control device applied to a vehicle including the rotating electrical machine capable of transmitting power to a drive wheel and an inverter electrically connected to the rotating electrical machine, the control device comprising:
a target value calculation unit that calculates a target value of a controlled variable that is torque of the rotating electrical machine, drive force of the rotating electrical machine, or acceleration of the vehicle, based on a redundant signal and a non-redundant signal;
an inverter operation unit that operates the inverter to control the controlled variable to the target value;
a monitoring value calculation unit that calculates a target monitoring value of the controlled variable based on the redundant signal; and
a difference calculation unit that:
determines whether the vehicle is traveling forward or rearward;
determines whether the target value is more than or equal to a positive first determination value when determining that the vehicle is traveling forward;
calculates a difference between the target value and the target monitoring value when determining that the target value is more than or equal to the positive first determination value;
does not calculate the difference when determining that the target value is less than the positive first determination value;
determines whether the target value is less than or equal to a negative second determination value when determining that the vehicle is traveling rearward;
calculates the difference when determining that the target value is less than or equal to the negative second determination value; and
does not calculate the difference when determining that the target value is more than the negative second determination value.
