Detailed explanation of the core components of automobile controllers

This article introduces the main components of the automotive controller in detail, including input, output and other auxiliary functions. First, the controller obtains input through sensors and communication buses, and after being processed by hardware circuits, it is input to the microcontroller. Secondly, the controller obtains control instructions through software algorithms and logic based on product functions and characteristics, and acts on the actuator in the form of current or voltage through the driver. In addition, the controller also designs hardware circuits to detect circuit status, increase storage space, resist electromagnetic interference, and facilitate circuit testing.
