摘要： A control target for a control device (10) is a vehicle drive device (1) including a rotating electrical machine (MG), and the control device (10) includes: an actual rotational speed obtaining part (14) that obtains an actual rotational speed (Nm) which is an actual rotational speed of the rotating electrical machine (MG); an actual torque obtaining part (15) that obtains actual torque (Tm) which is actual torque of the rotating electrical machine (MG); and a determining part (16) that determines a state of the rotating electrical machine (MG). The determining part (16) determines that the state of the rotating electrical machine (MG) is a negative torque abnormality, when the actual torque (Tm) has a negative value smaller than a torque threshold value (THt) set based on a relationship between the actual rotational speed (Nm) and target torque (Tmt) of the rotating electrical machine (MG).

摘要： A road surface condition estimation device (200) includes a control circuit (201), an acquisition circuit (202) and an estimation circuit (203). The control circuit (201) is configured to control a driving device that is able to independently drive a plurality of wheels. The acquisition circuit (202) is configured to acquire detection results of a plurality of wheel speed sensors that detects rotation speeds of the plurality of wheels respectively. The estimation circuit (203) is configured to calculate a slip ratio for each driving wheel, based on a detection result of a first wheel speed sensor and a detection result of a second wheel sensor. The estimation circuit (203) is configured to estimate a friction coefficient for each region on a road surface that corresponds to the driving wheel, based on the slip ratio.
