FILTERED BATTERY CURRENT BASED VEHICLE SPEED LIMITER
DRIVE
April 28, 2022
According to one embodiment, a vehicle includes an electrified propulsion system having an electric machine powered by a traction battery over an electrical distribution system (EDS). A controller is programmed to, reduce a speed limit of the vehicle from a maximum speed limit to an EDS speed limit in response to a measured average current of the EDS being within a threshold percentage of an average current limit of the EDS, and, in response to a measured speed of the vehicle exceeding the EDS speed limit, command a torque to the electric machine that is less than a driver-demanded torque such that the vehicle is propelled at a speed below the EDS speed limit.
