—— Vehicle Control Unit Abstract
The vehicle controller VCU is the center of energy management and torque coordination for pure electric vehicles. It plays a key role in the normal driving, starting control, driver interaction, braking energy recovery, network management, thermal management, fault diagnosis, vehicle status monitoring and display, overspeed protection, etc. it is the core component of electric vehicle control system. VCU is the core device to determine the driving performance, safety, energy consumption and power performance of pure electric vehicles.
