Principle and usage protocol of ESP interface

The principle of ESP interface mainly includes three parts: sensor data acquisition, controller processing and actuator control. Sensor data acquisition is responsible for converting the real-time information of the vehicle into electrical signals and transmitting them to the controller; controller processing is responsible for receiving sensor data and generating corresponding control instructions; actuator control is to send control signals to the actuator through the interface according to the instructions of the controller. The actuator may include the braking system, engine management system or other related systems. In terms of protocol, ESP interface usually adopts the CAN (Controller Area Network) protocol for vehicle network communication, which is a serial communication protocol widely used in the automotive field, providing a reliable and high-speed data transmission method.
