An electric vehicle (EV) comprises a vehicle wheel, a drive subsystem including a drive motor coupled with the vehicle wheel, and a control subsystem coupled to the drive subsystem and including a driver torque input configured to set a target propulsion torque. The control subsystem is configured to control the drive motor to apply the target propulsion torque to the vehicle wheel, determine a stalled condition of the drive subsystem during the application of the target propulsion torque, and, in response to determining the stalled condition, calculate a rollback torque, and control the drive motor to cancel the application of the target propulsion torque and to apply the rollback torque to the vehicle wheel, the rollback torque configured to allow the EV to travel down an incline at a rollback speed. The rollback torque comprises a lower torque value than a torque value of the target propulsion torque.
