Network management of the whole vehicle The vehicle controller is one of the many controllers of the electric vehicle and a node in the CAN bus. In vehicle network management, the vehicle controller is the center of information control, responsible for information organization and transmission, network status monitoring, network node management, and network fault diagnosis and processing.
The recovery of braking energy The important feature that distinguishes pure electric vehicles from internal combustion engine vehicles is the ability to recover braking energy, which is realized by operating the motor of pure electric vehicles in the regenerative braking state. The dynamic intention, the state of the power battery pack, and the state of the driving motor, combined with the braking energy recovery control strategy, send the motor mode command and torque command to the motor controller under the condition of satisfying the braking energy recovery, so that the driving motor works at In the power generation mode, the energy recovered by electric braking is stored in the power battery pack without affecting the braking performance, thereby realizing braking energy recovery.
