The HCU (Hybrid Control Unit) controls the overall hybrid systems and is connected with each of the control modules (ECM, TCM, MCU, BMS, ECU, etc.) via CAN. The hybrid system is controlled based on the brake switch signals.
NOTE:
CAN interface is divided into hybrid and chassis CAN lines.
The HCU controls power & torque distribution of the engine and motor, regenerative brake, and fail-safe mode based on the vehicle information, driver's demand, engine information and high voltage battery information.
