Automobile diagnosis data processing method and system

Abstract

The invention provides an automobile diagnosis data processing method and system. The system comprises a diagnosis protocol analysis module, a data packet processing module, a diagnosis data verification module, and a e diagnosis data access module. The diagnosis protocol analysis module is used for receiving a diagnosis request and carrying out the analysis of the diagnosis request to obtain a corresponding analysis result which at least comprises a diagnosis data request command corresponding to the diagnosis request; the data packet processing module is used for generating a data packet ina set format according to the analysis result, wherein the data packet in the set format comprises diagnosis data corresponding to the diagnosis data request command; the diagnosis data verification module is used for unpacking the data packet in the set format to obtain the diagnosis data request command and diagnosis data, and performing validity verification on the diagnosis data; and the diagnosis data access module is used for storing the diagnosis data request command and the successfully verified diagnosis data. According to the processing system, the SOC system is enabled to support the diagnosis service listed in ISO 14229-1: 2006 so that the diagnosis functions of the MCU and the SOC are enabled to be uniformly realized through the CAN network.

Description

Technical field [0001] The present invention relates to the technical field of automobile diagnosis data processing, in particular to a method and system for automobile diagnosis data processing. Background technique [0002] At present, the domestic and foreign automotive industries generally adopt the unified diagnostic service standard (ISO 14229-1: 2006) based on the on-vehicle controller area network (CAN) network communication framework promulgated by the International Organization for Standardization in 2006. The standard is based on the microcontroller (MCU), the control core of the traditional vehicle electronic control unit (ECU), and has been widely used and recognized in traditional vehicle ECUs such as engine controllers and body controllers. However, with the continuous introduction of new technologies such as artificial intelligence into the automotive industry, the new generation of in-vehicle ECUs such as in-vehicle multimedia audio-visual entertainment systems a...

Problems solved by technology

However, these solutions are more from the application point of view, trying to adapt to the existing functions of the vehicle, that is, it is impossible to go deep into the vehicle network level to unify the design

[0005] In the current system architecture design based on the coexistence of MCU and SOC, the diagnosis of MCU and SOC is usually implemented independently, that is, the diagnosis of MCU follows the ISO 14229-1:2006 standard through the CAN network, and the diagnosis of SOC often depends on the SOC. Depending on the type of operating system, it cannot be read through the CAN network of the vehicle for the time being
