Abstract
A vehicle is provided with a motor that is configured to provide drive torque and to facilitate regenerative braking. The vehicle also includes a controller that is configured to receive input that is indicative of a vehicle speed and a battery state of charge (BSOC), and to disable the drive torque when the BSOC is less than a maximum discharge limit. The controller is also configured to activate regenerative braking when the BSOC is less than the maximum discharge limit and the vehicle speed is greater than a predetermined speed.
