Abstract
An electric vehicle, and braking system and a method of operating the electric vehicle. The braking system includes a mechanical braking system, a regenerative braking system, and a controller. The controller is configured to calculate a total braking torque for operating the electric vehicle at a selected velocity during braking, determine an available regenerative braking torque via the regenerative braking system, calculate a mechanical brake torque for the mechanical braking system from the total braking torque and the available regenerative brake torque, and apply the mechanical brake torque at the mechanical braking system.
