Document Type and Number:
WIPO Patent Application WO/2020/066387
Kind Code:
A1
Abstract:
This control device (10) controls a vehicle drive device (1) provided with a rotating electric machine (MG), said control device (10) comprising: an actual rotation speed acquisition unit (14) that acquires an actual rotational speed (Nm), which is the actual rotational speed of the rotating electric machine (MG); an actual torque acquisition unit (15) that acquires an actual torque (Tm), which is the actual torque of the rotating electric machine (MG); and a determination unit (16) that determines the state of the rotating electric machine (MG). The determination unit (16) determines that the state of the rotating electric machine (MG) indicates a negative torque abnormality if the actual torque (Tm) is a negative value that is smaller than a torque threshold (THt) set according to the relationship between the actual rotational speed (Nm) and the target torque (Tmt) of the rotating electric machine (MG).
