Document Type and Number:
WIPO Patent Application WO/2021/035592
Kind Code:
A1
Abstract:
The present application provides a vehicle remote diagnosis method and device. The method includes: a device connector receives a TCP data packet of a diagnostic device through a data transmission control protocol TCP communication method and encapsulates it into a first data packet, and transmit the first data packet to a vehicle connector through remote communication; the vehicle connector converts the received first data packet into the TCP diagnosis instruction data packet and sends it to the vehicle; the vehicle connector receives the TCP diagnosis response data packet fed back by the vehicle according to the TCP diagnosis instruction data packet based on TCP communication, the vehicle connector encapsulates the TCP diagnosis response data packet into a second data packet and transmits it to the device connector through remote communication; the device connector converts the received second data packet into the TCP diagnosis response data packet and transmits it to the diagnosis device; the diagnosis device analyzes and processes the TCP diagnosis response data packet to obtain a diagnosis result and present it to a user. The technical solution of the embodiment of the present application realizes the remote diagnosis of the vehicle by remotely simulating DoIP local diagnosis.
