Abstract
A controller, while a motor is deactivated and a corresponding inverter is disabled, enables an engine for propulsion of a vehicle such that the motor rotates at a speed due to the propulsion, and commands variable voltage control circuitry to generate a target input voltage for the inverter that is based on a speed limit for the vehicle such that the speed of the motor corresponding to the vehicle travelling results in zero braking torque from the motor and zero charging current flow to a traction battery.
