Problems solved by technology

These ECUs are electronic products using new technology, and their maintenance requirements are relatively high. Due to the uneven technical level of drivers and maintenance personnel, when a fault occurs, it is difficult to analyze and find the problem in time, and it is difficult to eliminate the fault. to timely and effective
In addition, when it is necessary to upgrade the firmware or adjust the control parameters of an ECU for some reason, it is necessary to drive the vehicle to a designated place, and the maintenance personnel or professional service personnel will carry laptops, inverters and other related equipment on the vehicle, turn on the Manually update the controller shell, the operation is very cumbersome, time-consuming and labor-intensive

Abstract

The invention provides a remote update system and method for an electric automobile ECU. The remote update system comprises a transmission computer arranged at a remote data center and the ECU arranged at the vehicle-mounted end and further comprises a GPRS data transceiver arranged at the vehicle-mounted end and a data recorder, wherein the transmission computer is in interactive connection with the GPRS data transceiver through an Internet network platform and a mobile network platform, the GPRS data transceiver is in interactive connection with the data recorder, and the data recorder is in interactive connection with the ECU through an CAN bus. The invention further relates to the remote update method for the electric automobile ECU. The remote update of the electric automobile ECU program is achieved, accordingly program maintenance of vehicle factories or ECU suppliers can be convenient and quick, and the technical guarantee level is improved.

Description

technical field [0001] The invention relates to the technical field of electric vehicle control, in particular to a remote update method for an electric vehicle ECU. Background technique [0002] With the development of electric vehicle electronic technology and the continuous improvement of vehicle performance, there are more and more ECUs (electronic control units) on electric vehicles, such as motor drive system, battery management system, air conditioning system, high and low voltage control system, instrumentation and body control system, etc. These ECUs are all electronic products using new technologies, and their maintenance requirements are relatively high. Due to the uneven technical level of drivers and maintenance personnel, when a fault occurs, it is difficult to analyze and find the problem in time, and it is difficult to eliminate the fault. to be effective in a timely manner. In addition, when it is necessary to upgrade the firmware or adjust the control par...
