A control unit configured to control at least one motor of a vehicle is described that perform operations including receiving a target torque and a target speed for controlling the at least one motor, and determining, based on the target speed, a critical speed zone of the at least one motor. The critical speed zone defines a particular torque input to the at least one motor that induces torque ripple when the at least one motor is operating at any of a range of motor speeds. The operations performed by the control unit further include determining whether a current speed of the at least one motor is within the critical speed zone, and while determining that the current speed is within the critical speed zone, controlling a torque input to the at least one motor by avoiding the particular torque input defined by the critical speed zone.
