Abstract： OBD vehicle terminal can realize the capture of vehicle operation information, and then realize the status monitoring of vehicle, human and environment. Aiming at the present situation of single function of OBD products, a set of multifunctional OBD vehicle terminal equipment is designed and developed. Based on Infineon′s XMC4500 series 32-bit high performance processor, the hardware platform is equipped with 4G communication module and WiFi module to realize vehicle data upload and wireless network environment coverage. It is equipped with the MPU-9250 gyroscope to realize the detection of the 9-axis motion of the vehicle and support the read and write operation of SDHC large-capacity data. In order to enhance the user′s experience, digital FM audio module and tire pressure monitoring module are added to improve the user′s driving experience. This design can realize the collection and upload of vehicle engine parameters, calculate the data through the algorithm of upper computer platform, and provide reference for driving behavior and UBI insurance business.
