Abstract: Under the trend of "low carbonization, information and intelligence" in automobile industry, in order to meet the higher green, energy saving and efficient development requirements of new energy vehicles, this paper discusses in detail about a powertrain domain integration technology with high energy saving vehicle control unit. Firstly, proposes a high energy saving drive torque distribution method and an optimal braking energy feedback model and strategy, which can reduce vehicle energy consumption and improve driving range to a certain extent. Secondly, brings up a powertrain domain integration technology design, which integrates the control functions of battery management control unit, vehicle control unit, motor control unit and high voltage distribution control unit, simplifies the electronic system architecture, and makes the overall powertrain system more efficient.
