A method and system for processing vehicle diagnostic data

Abstract

The present invention provides a method and system for processing automobile diagnostic data. The system includes: a diagnosis protocol analysis module, which is used to receive a diagnosis request and perform analysis to obtain a corresponding analysis result. The analysis result includes at least a diagnosis data request corresponding to the diagnosis request command; a data packet processing module, configured to generate a formatted data packet according to the parsing result, wherein the formatted data packet includes diagnostic data corresponding to the diagnostic data request command; a diagnostic data verification module, It is used to unpack the data packet of the set format to obtain the diagnostic data request command and diagnostic data, and to verify the validity of the diagnostic data; the diagnostic data access module is used to save the diagnostic data request Command and verify successful diagnostic data. The processing system of the present invention enables the SOC system to support the diagnostic services listed in ISO 14229-1:2006, so that the diagnostic functions of the MCU and the SOC are uniformly realized through the CAN network.

Description

technical field [0001] The 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 automotive industry at home and abroad generally adopts the unified diagnostic service standard (ISO 14229-1:2006) promulgated by the International Organization for Standardization in 2006 based on the vehicle controller area network (CAN) network communication architecture. This 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 vehicle ECUs such as vehicle multimedia entertainment systems and intelligent driving co...

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
