CONTROL DEVICE AND CONTROL PROGRAM FOR ROTATING ELECTRICAL MACHINE

A target torque calculation unit (50) calculates a target torque, including a regenerative torque generated by regenerative power generation of a rotary electric machine (20), based on the operation amount of an accelerator operation member (11) and the operational state of a brake operation member (12). A monitoring torque calculation unit (70a) calculates a monitoring torque, which is used for monitoring the target torque, based on the operation amount of the accelerator operation member and the operational state of the brake operation member. An abnormality detection unit (70b) detects an acceleration abnormality when the target torque calculated by the target torque calculation unit exceeds the monitoring torque calculated by the monitoring torque calculation unit by a predetermined degree. A detection invalidation unit (70c) invalidates the detection of acceleration abnormality by the abnormality detection unit when the target torque is equal to or less than a mask threshold, and sets the mask threshold for a case where the brake operation member is not being operated higher than the mask threshold for a case where the brake operation member is being operated.
