CAN/LIN 통신제어기의 통합 모듈 개발에 관한 연구

Abstract

As the number of electronic control devices mounted in the vehicle increases, communication standards between electronic control devices are evolving. In particular, the recently released new car is equipped with various types of advanced driver assistance systems that receive and process information from camera sensors and radar, so more data must be exchanged quickly and safely. LIN and CAN are currently the most widely used in-vehicle communication standards, but their maximum communication speed is slow at 40 Kbit/s and 1 Mbit/s, respectively. CAN communication controllers and LIN communication controllers are essential when testing functions and performance after manufacturing in-vehicle devices. Since the CAN communication controller and the LIN communication controller are produced and sold as separate products, manufacturing costs of inspection equipment increase, and data processing speed decreases due to repeated data generation and transmission in the control PC. That is, there is a problem of incorrectly recognizing data loss due to data bottleneck as a defect in the device to be inspected. An integrated module was developed to solve this problem and software was developed in data transmission.
