Problems solved by technology

[0006] 1. There is a lack of hardware platform-related parameter definitions, and the specifications provided by AUTOSAR do not contain hardware-related parameter definitions
[0007] 2. The expansion capability of the parameter definition content is limited. Although the module implementer can modify the parameter definition according to the specific implementation method and hardware specification, it still cannot express specific parameter information
[0008] 3. The expansion capability of the parameter definition format is limited. AUTOSAR recommends to expand its parameter definition content in the MSR SDG (Simple Data Groups) format, but the format that this format can express is very limited, and it cannot support complex extended information of adding nodes in the parameter definition
[0009] 4. The management of parameter definitions is difficult. In the embedded field, hardware platforms are highly differentiated, and different chips, packages, peripheral circuits, etc. need to be considered. The method of designing a parameter definition for each specification of the hardware platform increases management cost

Embodiment Construction

[0026] Below in conjunction with accompanying drawing and embodiment the present invention will be further described:

[0027] The present invention will be further explained according to a specific RANGE tag and a corresponding parser, and according to the specifications of the MPC5634M-QFP144 chip. The main function is to define the mapping relationship between PortPinId and corresponding PortPinMode based on different PinPorts of the hardware platform, and provide a dynamic range query function for PortPinMode during configuration.

[0028] The implementation of this example is divided into the following steps:

[0029] 1. Create a RANGE tag to provide information about the non-continuous value range of the PortPin. Create a new SDG tag, the tag name is range, and the content of the tag is the corresponding parser ID, as shown in Table 1. Add this tag to the Admin Data tag of the PortPinMode configuration item in the Port module configuration parameter definition file. ...

Abstract

The invention relates to a basic software parameter definition extension method applied to AUTOSAR ECU configuration. The steps of the method are: adding an MSRSDG format label in the parameter definition file to provide an entry point for parameter definition extension; using a property file to provide actual parameters Defined extended information; In the basic software parameter definition file defined by the AUTOSAR specification Schema, add several tags in MSRSDG format to match the parser of the parameter extended information, and the parameter extended definition parser reads the current target hardware platform corresponding properties file, extended parameter definition information can be obtained through calculation, interpretation or query. Beneficial effects of the present invention: 1. Expansion of parameter definition content, on the basis of the original parameter model, SDG labels for interface style effects and module initialization can be established, and interface effects and functions can be enhanced. 2. Extended parameter definition format; 3. Support multiple hardware platform parameters; 4. Support dynamic calculation of parameter range and validity.

Description

technical field [0001] The invention relates to the technical field of automotive electronic software development, in particular to a basic software parameter definition extension method applied to AUTOSAR ECU configuration. Background technique [0002] AUTOSAR (AUTomotive Open System Architecture) is a standardized open automotive software architecture, and its normative content involves the development, integration, testing process and method of automotive electronic software, layered software module architecture and application interface, which the present invention refers to The AUTOSAR standard is version 3.1.5. [0003] ECU configuration is a link in the development process of AUTOSAR system. Such as figure 1 It is shown that its input is the ECU extraction of the system configuration (ECU Extract of System Configuration, hereinafter referred to as system extraction). On this basis, ECU configuration provides configuration information of all software in a single EC...
