Problems solved by technology

[0004] However, most of the current vehicle ECU online upgrade systems only support fixed buses and online upgrade protocols, and their portability and versatility are not strong. In the stages of product development, production and after-sales maintenance, different vehicle ECU online upgrade systems need to be configured Debug and maintain the product, which causes a great waste of product resources

Embodiment Construction

[0031] The present invention will be further explained below with reference to the drawings and examples.

[0032] This example is based on the CAN bus and uses a custom protocol to upgrade the ECU in the car online.

[0033] Such as figure 1 The shown online upgrade system for a vehicle ECU includes an upper computer 1 and a communication interface 9. The host computer 1 is connected to the vehicle-mounted ECU 10 through the communication interface 9, and the communication interface 9 is used to convert different communication buses into a consistent communication bus.

[0034] Such as figure 1 As shown, the host computer 1 includes a target file storage module 6, a target file analysis module 7, a parameter configuration module 4, a configurable file analysis module 5, a data processing module 3, a communication module 2 and a display module 8.

[0035] The target file storage module 6 stores target image files in multiple formats; for example: any one or more of .hex, .s19, .bin an...

The system comprises an upper computer and a communication interface; the upper computer is connected with the vehicle-mounted ECU through the communication interface; the upper computer comprises an object file storage module, an object file analyzing module, a parameter configuration module, a configurable file analysis module, a data processing module, a communication module and a display module; the object file storage module is coupled to the object file analyzing module, the parameter configuration module is coupled to the configurable file analysis module, the data processing module is coupled to the object file analyzing module, the configurable file analysis module, the communication module and the display module, and the communication module is connected with the communication interface. Universality and reusability of the ECU online updating system are enhanced.

Description

Technical field [0001] The invention relates to the field of automotive electronic engineering, in particular to an on-line ECU upgrade system and method for a vehicle. Background technique [0002] With the rapid increase of software functions in the field of automotive electronics, new technologies continue to be applied. In the production and after-sales maintenance stages of automotive electronic products, it is often necessary to update the application programs in the ECU (Electronic Control Unit) and modify the system parameters. The traditional solution is to remove the ECU module from the vehicle and install it in the vehicle after updating the application program. However, in many cases, the controller installed in the vehicle is not easy to disassemble, and the equipment is frequently disassembled. Plugging and unplugging the ECU is not only troublesome but also easy to damage the circuit board. [0003] With the continuous development of bus network technology, in order...
