Electric vehicle control device and method for controlling electric vehicle control device

A method for controlling an electric vehicle control device that controls a vehicle traveling via a transmission coupled to a plurality of electric motors as a drive source, wherein

• the transmission includes a first transmission and a second transmission each incorporating a liquid medium,
• the electric motor includes a first electric motor and a second electric motor that are in contact with the first transmission and the second transmission, respectively, and
• in a heating period in which the first transmission or the second transmission is heated, one of the first electric motor and the second electric motor is driven and controlled with a powering torque obtained by increasing a heating component torque to a required torque of the electric motor, and an other of the first electric motor and the second electric motor is controlled with a torque obtained by subtracting the heating component torque from a required torque of the electric motor,
• wherein in the heating period in which the first transmission or the second transmission is heated, the one of the first electric motor and the second electric motor is driven and controlled, by a controller, with the powering torque, and the other of the first electric motor and the second electric motor is controlled by the controller to perform regenerative control with a regenerative torque corresponding to the heating component torque.
