Problems solved by technology

[0005] Each configuration parameter in the ECU configuration tool has a strong correlation, and the value of one parameter will affect the value of other parameters. The existing solution is to use the Eclipse EMF framework to realize the monitoring mechanism between each configuration parameter, but the solution There are still disadvantages in actual use, mainly reflected in the fact that the efficiency of the scheme will become very low

Embodiment Construction

[0020] Below in conjunction with accompanying drawing and embodiment example the present invention will be further described:

[0021] In the following, the present invention will be further explained according to a specific configuration parameter dependence relationship and according to the specifications of the TC1767 chip. The main function is that in the configuration of the PWM module in ECUC, when the Channel Class is configured as the PWM_FIXED_PERIOD_ZERO_SHIFTED parameter, the Polarity function will be disabled; when the Channel Class is configured as other parameters, the Polarity function will be enabled.

[0022] The implementation of this example is divided into the following steps:

[0023] 1. Determine the dependencies between configuration parameters. In this case, the Channel Class parameter is the trigger parameter, and the Polarity parameter is the dependent parameter.

[0024] 2. Specify a TRIGGER tag, which is used to provide PwmChannelClass as a trigge...

Abstract

The invention relates to the technical field of automotive electronic software development, in particular to a monitoring mechanism applied to an AUTOSARECU (automotive open system architecture electronic control unit) configuration interface. According to dependency of ECU configuration parameters, the monitoring mechanism for the parameters is built, and finally monitoring for the parameters is embodied by the effect of the ECU configuration interface. A monitoring method includes: dividing the configuration parameters into trigger parameters and dependency parameters; adding monitoring identifiers pointing to the trigger parameters into a wrapper class of the dependency parameters; and allowing the dependency parameters to change according to current values of the trigger parameters when the values of the trigger parameters are changed. The monitoring mechanism can be used for effectively implementing dependency of the ECU configuration parameters based on AUTOSAR standards, overcoming the shortcomings of cumbersomeness and time consumption of a monitoring mechanism in an EMF (eclipse modeling framework), optimizing the response time of the mutually dependent parameters in the same configuration interface, and improving the user experience of an ECU configuration tool.

Description

technical field [0001] The invention relates to the technical field of automotive electronic software development, in particular to a monitoring mechanism applied to an AUTOSAR ECU configuration interface. Background technique [0002] AUTOSAR (AUTomotive Open System Architecture) is a standardized open automotive software architecture, and its normative content relates to the development, integration, and testing process and method of automotive electronic software, layered software module architecture and application interface. 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. like figure 1 It is shown that its input is the ECU extraction of 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 ECU, covering RTE configurat...
