As the core component of the target vehicle system architecture, the VCU achieves the established optimal matching goals of the motor, battery and transmission system based on the collection of parameters such as the driver's operating instructions, vehicle speed, motor speed, SOC and water temperature. The development of a high-performance, low-cost VCU has a very important impact on the power, economy, safety and other vehicle performance of new energy vehicles.
