Abstract

The invention discloses an Ethernet diagnosis communication line and communication method for a vehicle and is used for solving the problem of how to carry out ECU (Electronic Control Unit) programming through a vehicle Ethernet technology. One end of the Ethernet diagnosis communication line for the vehicle is equipped with a first interface connected with an ECU programming device, and the otherend is equipped with a second interface connected with an ECU of the vehicle. An Ethernet integrated circuit and an Ethernet transformer are set between the first interface and the second interface on the Ethernet diagnosis communication line for the vehicle. A protocol conversion drive program is pre-burnt on the Ethernet integrated circuit and is used for converting a programming signal from the first interface into a TCP / IP protocol signal. The Ethernet transformer is used for isolating the converted TCP / IP protocol signal and inputting the TCP / IP protocol signal into a TCP / IP protocol network of the vehicle through the second interface, so the ECU of the vehicle finishes ECU programming according to the TCP / IP protocol signal.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a vehicle Ethernet diagnosis communication line and a communication method. Background technique [0002] A computer called ECU (Electronic Control Unit, trip computer) in the car controls fuel injection, ignition and vehicle emissions (indirectly). The software that runs on the ECU is called "firmware" because it is harder to change than normal software. 1 ECU can be used in many different cars by changing its firmware. In fact, 1 type of car can adapt to the emission regulations of different countries by updating the firmware. After the car leaves the factory, upgrading the firmware can also fix bugs and reduce emission output. [0003] In the automotive service industry, by reprogramming the ECU, system operating parameters can be changed and calibrated, bugs can be repaired and emissions can be reduced. However, various reprogramming requirements and the necessary pro...
