ELECTRIFIED REAR AXLE REGENERATIVE HAND BRAKE
DRIVE
January 29, 2026
An electrified rear axle regenerative handbrake system for an electrified vehicle includes an electric motor, a rear axle, a handbrake and a controller. The rear axle receives input from the electric motor and transmits torque to rear wheels of the electrified vehicle. The handbrake moves between an unactuated position and an unactuated position and generates a handbrake signal based on a sensed position thereof. The controller receives the handbrake signal; receives a speed and direction of the rear axle; determines a rear axle braking torque command based on the handbrake signal, and the speed and direction of the rear axle; and commands the electric motor to implement a rear axle braking torque based on the determined rear axle braking torque command.
