Abstract
An electric drive system is actively controlled while an electrified vehicle is being towed. The inverter switches are manipulated to preclude exceeding a maximum voltage of a DC bus and also to preclude exceeding a maximum phase current magnitude. During a transition from an inverter off state to a short-circuit state, field-oriented control is utilized.
