SYSTEM DESCRIPTION

With regenerative braking, the traction motor functions as an alternator during deceleration, and the deceleration energy that is transmitted from the vehicle wheels is converted to electrical energy and used to charge the
Li-ion battery.

REGENERATIVE BRAKE CONTROL

If the brake pedal is depressed during driving, the electrically-driven intelligent brake unit transmits the braking force and cooperative regenerative practicable torque signal to HPCM via CAN communication. Based on these signals, HPCM calculates the regenerative braking torque, and transmits the drive command signal to the traction motor inverter. HPCM also transmits the actual regenerative braking value to the electrically-driven intelligent brake unit by CAN communication, allowing the electrically-driven intelligent brake unit to perform overall brake force control.
For electrically-driven intelligent brake system cooperative control, Cooperative Regenerative Brake Function.
