Hybrid Control System

Description

The HCU (Hybrid Control Unit) controls whole hybrid systems and is connected with each control modules (ECM, TCM, MCU, BMS ECU etc.) by CAN interface. In addition this system uses the brake switch and Clutch Pressure Sensor (CPS) signals for controlling the hybrid system.

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.
