—— Overview Of Hybrid Control Unit
The hybrid control unit is the center of energy management and torque coordination for hybrid electric vehicles. It plays a key role in normal driving, starting control, clutch control, planetary gear control, driver interaction, braking energy recovery, network management, thermal management, fault diagnosis, vehicle condition monitoring and display, overspeed protection, etc The core component of automobile control system. HCU is the core device to determine the driving performance, safety, energy consumption and power performance of hybrid electric vehicles.
The HCU solutions provided by Huahai Technology Co., Ltd. cover all kinds of hybrid power architectures from P0 to P4 and PS. based on mature hardware platform, the control algorithm takes into account vehicle energy consumption, power performance and long-term reliability.
