Vehicle Real-time Condition Monitoring Based on CAN Bus

Abstract Because the automobile in the driving process there will be some hidden dangers, once the hidden dangers occur is likely to have a safety accident, then the driver’s safety will be endangered. In order to avoid this situation, this paper introduces multi-sensor communication under the CAN bus, using the CAN interface of STM32F103 MCU to transmit data with multi-sensor in real time. The high performance and reliability of CAN have been recognized, and it has been widely used in the field of automobile communication. It provides powerful technical support for the real-time and reliable data exchange of distributed control systems among nodes. Displaying the final result on the display when communicating with multiple sensors allows the driver to monitor the status of the car in real time and process it in the first place, providing a safety guide for driving.
