BorgWarner Supplies Next-Generation Triple-clutch P2 Drive Module to HYCET Transmission

  • BorgWarner provides a highly integrated triple-clutch P2 drive module and electro-hydraulic control unit for HYCET Transmission, a wholly-owned subsidiary of Great Wall Motors for its Haval and WEY brands
  • Applied to the world’s first P2 9-speed 9HDCT hybrid transmission by HYCET
  • Partnership further drives the development of hybrid vehicles

Auburn Hills, Michigan, September 28, 2021 – BorgWarner has extended its cooperation with  HYCET Transmission Technology Hebei Co., Ltd. by supplying BorgWarner’s triple-clutch P2 drive module and hydraulic control unit to Great Wall's Haval  and WEY brands. As a leading supplier in the global HEV market, BorgWarner supports the world's first 9-speed P2 9HDCT hybrid transmission for HYCET "I-Era 2.0" powertrain. The hybrid transmission features nine gears and a parking lock function for greater vehicle efficiency and performance.

With the electric motor placed directly between the internal combustion engine and the transmission, BorgWarner’s on-axis P2 drive module, which matches HYCET delivers cost-effective hybridization through its compatibility with existing vehicle platforms. This innovative BorgWarner P2 solution has a compact axial and outstanding performance and is capable  of integrating up to three clutches, including a disconnecting clutch. This allows the system to decouple from the engine for pure electric driving, enabling the vehicle to always provide sufficient power performance when the engine is not working or in inefficient areas. BorgWarner's P2 hydraulic control unit for HYCET adopts a next-generation low-leakage design to further improve the efficiency of the hydraulic system. The latest solenoid valve is also designed for optimized clutch and shifting characteristics, resulting in better system efficiency and performance.

With the development of hybrid technology and subsidy policy adjustments, OEMs are exploring more possibilities for energy conservation and emission reductions in the combustion-fueled vehicles space, thus elevating the role of hybrid vehicles. Among various hybrid structures, BorgWarner’s P2 solution has been widely recognized by car makers as a highly efficient and fast-to-market hybridization technology.

“We are thrilled to extend our nearly two-decade partnership with HYCET” said Dr. Volker Weng, President & General Manager, BorgWarner DriveTrain Systems. “Our customized triple-clutch P2 module can meet the requirements for HYCET’s 9-speed 9HDCT hybrid powertrain and is especially suitable for P2 hybrids that are expected to become the mainstream of hybrid architectures.”

BorgWarner’s on-axis P2 drive module can be installed directly into the drive shaft for easy integration. The compact design with up to three nested clutches minimizes overall length, enabling OEMs to integrate it with a variety of engines and vehicle platforms, including high voltage PHEV, high voltage HEV and 48V systems. The company’s triple-clutch P2 module integrates the disconnecting clutch, the drive motor and the cooling system, and features a high-performance, low-noise stator delivering 95% peak efficiency.

By using BorgWarner’s award-winning S-wind wire-forming process to create the motor, the P2 drive module produces high power and torque densities in an extremely compact package. The innovative manufacturing process allows BorgWarner to produce smaller, more powerful high-voltage electric motors on a mass scale and is expected to help drive growth in the hybrid and electric vehicle market. In addition, BorgWarner can supply the electrohydraulic controls for actuating the wet clutches, giving customers the option to choose individual components or a complete system.

It is reported that the hybrid vehicles equipped with BorgWarner's triple-clutch P2 hybrid drive module and hydraulic control unit will have mass produced by the end of January 2022.
