Document Type and Number:
Japanese Patent JP2022076536
Kind Code:
A
Abstract:
To provide a control device of an electric vehicle capable of suppressing temperature rise of a switching element of an inverter by considering electric current flowing to an arm of the inverter in a reverse direction, which is generated when reducing torque at lock determination time.SOLUTION: A control device 30 reduces a torque command value TR2 of a motor generator MG2 to a prescribed value Dt when determining a lock state of the motor generator MG2, and thereafter controls an inverter 14 so that the torque command value TR2 reduces at a variable rate in which a torque reduction rate becomes small according to lapse of time.SELECTED DRAWING: Figure 5
