Problems solved by technology

At present, the traditional method of upgrading the program is to remove the board or solder the circuit chip through the personnel ECU, and manually write it offline with the help of the lower computer. This will take up a large part of the time, manpower, and financial resources, and the work efficiency is low, and it is easy to make mistakes.

Embodiment Construction

[0060] A method for realizing remote upgrade of vehicle ECU based on UDS communication protocol, including equipment cloud server, vehicle TBOX (Telematics BOX), TSP (Telematics Service Provider, vehicle remote service provider) management system, and vehicle ECU.

[0061] 1. UDS diagnostic upgrade process:

[0062] UDS (Unified diagnostic services) is for all ECUs of the vehicle. It's just an application layer protocol (ISO 14229-1), so it can be implemented both on the CAN wire and even on the Ethernet. And UDS provides a basic framework of diagnostic services, OEMs and parts suppliers can choose to implement some of them or customize some privatized diagnostic services according to the actual situation.

[0063] The on-board ECU of the whole vehicle is connected to the on-board TBOX through the CAN bus; the CAN bus is divided into the power CAN bus PTCAN, the body CAN bus BCAN, and the information CAN bus InfoCAN (such as figure 1 PTCAN is connected to: vehicle controller...

Abstract

The invention relates to vehicle ECU remote upgrading equipment and a vehicle ECU remote upgrading method, and provides a method for realizing vehicle ECU remote upgrading based on a UDS communicationprotocol in allusion to the current situation that different vehicle factories need to independently develop respective vehicle ECU remote upgrading systems. The method is based on CAN communicationdata of a vehicle. A vehicle UDS diagnosis protocol and a remote monitoring platform scheme are compiled; remote data upgrading of the vehicle ECU is achieved through the hardware vehicle-mounted terminal 4G module, manual offline upgrading of the ECU is not needed any more, the upgrading time of the vehicle ECU can be set at the background, and the ECU is upgraded automatically through remote networking after the set time is up. An ECU delivery recovery mechanism is specified in the UDS protocol, and the situations of ECU crash damage, data loss and the like caused by networking failure in the upgrading process are avoided. By establishing the cloud platform, the vehicle-mounted hardware and the data management algorithm and combining the UDS diagnosis protocol for encryption security access, ECU upgrading is safer and more convenient.

Description

technical field [0001] The invention relates to a vehicle ECU remote upgrade device and method, in particular to a method for realizing vehicle ECU remote upgrade based on a UDS communication protocol. Background technique [0002] Cars are becoming more and more common in life, and more and more vehicles often have many problems after mass production. Depots need to control the ECU (Electronic Control Unit, electronic control unit, also known as "trip computer", "On-board computer", etc.) to upgrade, generally requires the owner to drive the car to the designated 4S shop or return to the factory, and specialized staff to manually upgrade the ECU. At present, the traditional method of upgrading the program is to remove the board or solder the circuit chip through the personnel ECU, and use the lower computer to manually log off and write. [0003] There have been many applications in the field of intelligent technology for remote control and data monitoring of vehicles. Ve...
