Problems solved by technology

Since the Bluetooth protocol supports multi-data transmission, when more data needs to be transmitted, such as hundreds of bytes of data, the transmission time will be longer. For vehicle communication, a longer transmission time will easily lead to poor real-time performance and affect user experience. ride experience

Abstract

Embodiments of the present invention provide a vehicle data transmission system and method. The vehicle data transmission system includes a user terminal, a vehicle-mounted Bluetooth component that communicates with the user terminal through a first link, and a vehicle-mounted Bluetooth component that communicates with the vehicle-mounted Bluetooth component through a second link. A communication control component, wherein the data transmitted in the first link and the second link have the same data packaging format, and the first data corresponding to the data packaging format sent by the user terminal is received through the vehicle-mounted Bluetooth component, and then the first data corresponding to the data packaging format is received. One data is converted into the second data corresponding to the data packing format and directed to the control component, and then the second data is sent to the control component by means of multi-frame continuous transmission, and the control component performs the corresponding operation according to the second data, thereby The data transmission time is reduced, the data transmission efficiency is improved, and the real-time nature of vehicle data transmission is ensured.

Description

technical field [0001] The present invention relates to the technical field of vehicle data processing, in particular to a vehicle data transmission system and a vehicle data transmission method. Background technique [0002] With the development of vehicle intelligence, Bluetooth is more and more widely used in vehicles. When the user terminal sends multiple data commands to the in-vehicle Electronic Control Unit (ECU) through Bluetooth and requires fast response, based on the current traditional Controller Area Network (CAN), a frame of message is used. Transfer 8 bytes of data. Since the Bluetooth protocol supports multi-data transmission, when more data needs to be transmitted, such as data of several hundreds of bytes, the transmission time will be longer. For vehicle communication, the longer transmission time will easily lead to poor real-time performance and affect users' ride experience. SUMMARY OF THE INVENTION [0003] In view of the above problems, embodimen...
