Abstract: Presented are motor control systems, vehicles, and methods for generating motor heat while holding an offset motor torque during stationary vehicle operation. A method of operating an AC motor includes a resident or remote vehicle controller receiving a mode request to operate a vehicle in a stationary mode, and a temperature request including the AC motor generating motor heat during the stationary operating mode.

Using a DQ transform model of the AC motor, the controller selects multiple dq current trajectories located in respective dq operating quadrants of the DQ transform model based on the offset motor torque. The controller then commands a power inverter to transmit electrical current to the AC motor based on the select dq current trajectories.
