Problems solved by technology

Due to the forward-looking and universality of AUTOSAR, LIN, CAN and FlexRay are the mainstream when selecting the vehicle bus, and the services in ISO14229, ISO15765 and ISO 15031-5 are adopted as diagnostic standards. However, LIN, CAN The AUTOSAR system with the bus structure of FlexRay cannot meet the needs of a large number of existing vehicles and diagnostic equipment through K-line communication and KWP2000 diagnosis in the market
Considering that the popularization and promotion of AUTOSAR is currently difficult, and K-line diagnostic communication will not withdraw from the market in the short term, if AUTOSAR does not support K-line communication diagnosis, it will undoubtedly greatly limit the use of AUTOSAR basic software. ECU (Electronic Control Unit electronic control unit) and diagnostic equipment greatly restrict the development and promotion of AUTOSAR, making it impossible for many ECU development and maintenance personnel to enjoy the convenience brought by AUTOSAR

Embodiment Construction

[0031] In order to make the above objects, features and advantages of the present invention more comprehensible, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0032] Such as figure 1 and figure 2 As shown, the present invention provides a K-line diagnosis method compatible with AUTOSAR. The communication protocol stack of the AUTOSAR basic software includes respectively a communication service layer 1, a communication hardware abstraction layer 2 and a communication driver layer 3, and each layer is composed of several modules . Wherein, the present embodiment increases the K-line driver module, the K-line interface module, and improves the DCM module, and the method includes:

[0033] Step S1, adding a K-line driver module to the communication driver layer 3 of AUTOSAR.

[0034] Preferably, the K-line driver module completes the initialization of the physical layer of the K-line, a...

Abstract

The invention relates to an automotive open system architecture (AUTOSAR)-compatible K line diagnostic method and an AUTOSA-compatible K line diagnostic system. The method comprises the following steps: adding a K line driving module at a communication driving layer of the AUTOSAR; adding a K line interface module at a communication hardware abstract layer of the AUTOSAR; and adding an international standardization organization (ISO) 14230 standard diagnostic service of a key word protocol (KWP) 2000 diagnostic protocol in a data control memory (DCM) module of the AUTOSAR communication service layer. By adopting the invention, AUTOSAR basic software can be enriched, so that the AUTOSAR can support the K line communication and ISO 14230 diagnostic protocol stack, therefore a solution of the perfect and integrated communication diagnostic software is provided for customers.

Description

technical field [0001] The invention relates to a K-line diagnosis method and system compatible with AUTOSAR. Background technique [0002] The K line is a communication bus used in the vehicle industry for diagnostics and calibration. The diagnostic equipment conducts half-duplex serial communication with the ECU through the K line. Since the early 1990s, with the promulgation of ISO9141 and ISO14230 series of diagnostic standards, K-line diagnosis has been widely used among various vehicle manufacturers and parts suppliers. [0003] AUTOSAR (Automotive Open System Architecture) is supplied by major foreign automakers such as BMW, Bosch, Continental, DaimlerChrysler, Ford, Opel, P SA Peugeot Citroen, Siemens, Toyota, Volkswagen, as well as electronic systems, semiconductors, and software. It is a standard jointly sponsored and formulated by China and China since 2003. The purpose of the AUTOSAR organization is to manage the complexity of electronic and electrical systems...
