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.

A kind of monitoring mechanism that is applied to the ECU configuration interface

Technical field

The present invention relates to automotive electronics software development technique field, especially a kind of monitoring mechanism that is applied to AUTOSAR ECU configuration interface.

Background technology

AUTOSAR (AUTomotive Open System Architecture) is a standardized open automobile software architecture; Its normative content has related to flow process and method, delamination software module architectures and the application interface of automotive electronics Development of Software, integrated, test, and the AUTOSAR standard of institute of the present invention reference is the 3.1.5 version.

The ECU configuration is link in the AUTOSAR system development flow process.Its input as shown in Figure 1 is that the ECU of system configuration extracts (ECU Extract of System Configuration extracts hereinafter to be referred as system).The ECU configuration provides the configuration information of all softwares in the single ECU on this basis, and content has contained the configuration of RTE configuration and each basic software assembly.The output of ECU configuration is the ECU configuration describing document, and it can be used for generating and be structured in ECU goes up executable file.

For the intermediate product in the performance history of standardizing, be convenient to integrated between developing instrument, AUTOSAR provides Schema file.The parameter definition file of ECU configuration parameter description document and basic software module must meet the call format of Schema regulation.AUTOSAR provides a standardized ECU configuration parameter defined file simultaneously, has at length defined the parameter item of hardware independent, and supports the realization side of each basic software module to revise parameter-definition on this basis.The ECU configuration tool provides corresponding configuration interface according to the definition of these parameters, after the enterprising line correlation configuration of graphical interfaces, configuration information is offered follow-up configuration code generation phase through the ECU configuration describing document by the user.

Each configuration parameter has very strong correlativity in the ECU configuration tool; A values of parameters will influence other values of parameters; Existing scheme is to utilize Eclipse EMF framework to realize the monitoring mechanism between each configuration parameter; But still have its drawback in the actual use of this scheme, the efficient that is mainly reflected in scheme will become very low.

Summary of the invention

The object of the invention will solve the deficiency that above-mentioned technology exists just, and a kind of monitoring mechanism of the ECU of being applied to configuration interface is provided, and uses this method to optimize the response time between the complementary parameter greatly, has improved the user experience of ECU configuration tool.

The technical scheme that the present invention adopts is a kind of monitoring mechanism of the ECU of being applied to configuration interface, and the step of this scheme is:

1) confirms dependence between the configuration parameter; Configuration parameter is divided into two types, and a kind of is trigger parameter, and another kind is to rely on parameter; The class of trigger parameter encapsulation has a triggering audiomonitor; Rely on parameter and come the state of monitoring triggering parameter through an indications class, when trigger parameter changed its value, relying on the values of parameters or the form of expression will change;

2) on existing parameter-definition model, trigger parameter is customized general SDG (Simple Data Groups comprises tag name, label additional content two parts information) label.Add basic parametric representation additional information above that; Label is added in the management data Admin Data label of target component definition, promptly in basic software block configuration parameter definition file, label is added in management data (Admin Data) label of target component defined item.

3) with the implementation language of Java language as ECU configuration interface monitoring mechanism, the Cell that belongs to for trigger parameter is provided with the triggering audiomonitor.(Cell refers to the configuration block of parameter in the configuration interface.)

4) will rely on parameter and trigger parameter associates, in expression relies on the class of parameter, add the identifier of trigger parameter.

The present invention possesses following advantage:

1. abandon the monitoring mechanism of EMF framework, optimized the response time that the dependence parameter changes trigger parameter.

2. utilize SDG labeled marker trigger parameter and combine resolver and property file, make the expression format of parameter-definition more versatile and flexible.

3. rely on parameter and be encapsulated in the different classes, reduced the degree of coupling of configuration tool with trigger parameter.

Embodiment

Below in conjunction with accompanying drawing and case study on implementation the present invention is described further:

According to a concrete configuration parameter dependence, the present invention is further illustrated below according to the specification of TC1767 chip.Main function is in the PWM block configuration in ECUC, and when Channel Class was configured to the PWM_FIXED_PERIOD_ZERO_SHIFTED parameter, the Polarity function will be closed; When Channel Class is configured to other parameters is that the Polarity function will be unlocked.

The enforcement of this instance is divided into following steps and carries out:

1, confirms dependence between the configuration parameter.Channel Class parameter is a trigger parameter in this case, and the Polarity parameter is for relying on parameter.

2, specify a TRIGGER label, being used for externally providing PwmChannelClass is a trigger parameter.A newly-built SDG label, label is called trigger, and tag types is Boolean type, and is as shown in table 1.The PwmChannelClass that this label is joined in the PWM block configuration parameter definition file enumerates in the Admin Data label of parameter configuration item.

Table 1 adds the trigger label in the PwmChannelClass configuration item

3, be the Cell adding triggering audiomonitor at Channel Class parameter place, and realize trigger.Trigger the task of will accomplishing be exactly whether other Cell among this CellView at inspection Channel Class place depend on Channel Class, if this Cell depends on Channel Class, then this Cell is upgraded.Concrete process flow diagram is seen Fig. 2.

4, in the encapsulation class of Polarity parameter, add the information that depends on Channel Class parameter.Suppose this encapsulation type PwmPolarity by name, it has inherited the TriggeredDecorator abstract class, and is as shown in Figure 3, and has realized that the method for getWatchingAnchors has also added the sign of PwnChannelClass therein, as shown in table 2.

The method of table 2 getWatchingAnchors realizes

5, then can realize the monitoring mechanism of correlation parameter in the ECU configuration interface through above step, the case effect is seen Fig. 4.

At last, it is also to be noted that what more than enumerate only is practical implementation example of the present invention.Obviously, the invention is not restricted to above examples of implementation, many distortion can also be arranged.All distortion that those of ordinary skill in the art can directly derive or associate from content disclosed by the invention all should be thought protection scope of the present invention.
