Abstract

Systems, methods, and vehicles for closed-loop control of regenerative braking. The system includes, in one implementation, a regenerative braking subsystem and a vehicle controller. The vehicle controller is configured to command the regenerative braking subsystem to apply a first amount of regenerative braking torque. The vehicle controller is also configured to determine a current vehicle deceleration while the first amount of regenerative braking torque is applied. The vehicle controller is further configured to determine a difference between the current vehicle deceleration and a target vehicle deceleration. The vehicle controller is also configured to set a second amount of regenerative braking torque to reduce the difference between the current vehicle deceleration and the target vehicle deceleration. The vehicle controller is further configured to command the regenerative braking subsystem to apply the second amount of regenerative braking torque.
