New-energy vehicle ECU remote program updating management system and method

Abstract

The invention discloses a new-energy vehicle ECU remote program updating management system and method. The system comprises an enterprise platform side and a vehicle-mounted terminal, and the enterprise platform side comprises a program importing unit, an information extraction conversion unit, a program updating library unit, a vehicle management unit and a program issuing unit; the vehicle-mounted terminal comprises a storage unit and an updating unit which are connected; according to the updating management process, an updating program is imported and converted into a standard format, the updating program is issued to a vehicle owner side according to the vehicle ECU model and ECU program version number matching state, and the vehicle-mounted side under the enable state is subjected toprogram updating. The updating program adopTS the universal format, the requirement for vehicle-mounted terminal hardware is lowered, and the cost is lowered; due to the method for controlling the program updating opportunity jointly by a VCU and an ECU needing to be updated, the imponderable risk caused by program updating in the vehicle using process is avoided; ECU program updating among different CAN sub-neTS of vehicles is achieved, and illegal program updating is avoided.

Description

technical field [0001] The invention relates to the technical field of vehicle-mounted remote control, in particular to a system and method for remote program update management of an ECU of a new energy vehicle. Background technique [0002] There are also some disadvantages in the existing method for updating the remote program of the automotive ECU: [0003] 1. The program file updated by the vehicle terminal is an S19 format file. The premise of being able to remotely update the program is that the main control chip of the ECU must support the S19 file. But the fact is that not all main control chips currently support program download and update in S19 format, and this solution has limitations. [0004] 2. There are multiple CAN networks in the vehicle (power CAN, body CAN, etc.), and multiple CAN networks are connected through a gateway. If the ECU and the vehicle terminal are not in the same network, there is no way to update the program in the existing solution. [...

AI Technical Summary

Problems solved by technology

If the ECU and the vehicle terminal are not on the same network, there is no way to update the program in the existing solution

[0005] 3. It is forbidden to update the ECU program when the vehicle is running, charging or in other operating states, because the ECU program update process is an abnormal working process, and if the program is updated forcibly, it may bring safety hazards to the vehicle

[0006] 4. Without version control and product model verification functions, it is prone to program error updates or repeated updates
