Abstract
A vehicle control system for controlling a vehicle deceleration rate that includes a dynamo (e.g. generator/motor) coupled to the vehicle to provide a dynamo deceleration force to the vehicle corresponding to an electric load, an internal combustion engine coupled the vehicle to provide an engine deceleration force to the vehicle corresponding to a throttle position, and a controller coupled to the internal combustion engine and the dynamo. The controller is configured determine a deceleration fuel cutoff (DFCO) request based on an accelerator pedal position, and when a DFCO request is determined increase the throttle position to decrease the engine deceleration force, and increase the electric load on the dynamo to increase the dynamo deceleration force, to control the vehicle deceleration rate.
