It has the following functions:
1) Receive information input from sensors or other devices, and convert the input information into signals that can be received by the microprocessor;
2) Store, calculate, analyze and process information, analyze the program used for output values, store the characteristic parameters of the vehicle model, the data in the calculation (store and retrieve at any time), and store fault information;
3) Calculation analysis. Calculate the execution command data based on the information parameters, compare the input information with the standard value, and investigate the fault.
4) Output execution command. Convert weak signals into execution commands, output fault information, and self-correct.
