Embodiment Construction

[0031] Hereinafter, the control device 10 of the vehicle drive device 1 according to the embodiment will be described with reference to the drawings. The control device 10 is a device having the vehicle drive device 1 as a control object. The control device 10 is mounted on the vehicle together with the vehicle drive device 1 . In the present embodiment, the internal combustion engine control device 20 is also mounted on the vehicle. The internal combustion engine control device 20 is a device that controls the internal combustion engine ENG as a driving force source.

[0032] 1. Configuration of vehicle drive unit

[0033] First, the configuration of the vehicle drive device 1 will be described. Such as figure 1 As shown, the vehicle drive device 1 includes a rotating electric machine MG. In this embodiment, the vehicle drive device 1 further includes: an input shaft I, which is drivingly connected to the internal combustion engine ENG; an output shaft O, which is drivin...

Abstract

A 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).

Description

technical field [0001] The present invention relates to a control device having a vehicle drive device including a rotating electric machine as a control object. Background technique [0002] Conventionally, in a vehicle drive device configured as described above, a technique for determining an abnormality of a rotating electric machine is known. For example, Patent Document 1 below discloses that, when the phase current supplied to the rotating electrical machine exceeds an allowable value during rotation of the rotating electrical machine, it is determined that an overcurrent abnormality has occurred and control is performed to decrease the rotational speed of the rotating electrical machine. technology. [0003] However, in the vehicle drive device configured as described above, when some kind of failure occurs, the possibility that the rotary electric machine outputs an unexpected negative torque is not zero. When such an unexpected negative torque is generated in the ...
