[0038] In the "bottom-up" workflow of the AUTOSAR system solution, it is necessary to establish the software components of Autosar based on the existing Simulink model. At present, the SWC method of establishing the application layer is relatively flexible according to the different functions and modules.

The following first introduces the shift module AUTOSAR software component development method based on Simulink provided by the present application embodiment.

[0040] Figure 1 FIG. 1 is a flow chart of a method for developing AUTOSAR software components for a gear shift module based on Simulink provided by an embodiment of the present application. Figure 1 As shown, the AUTOSAR software component development method of the shift module based on Simulink includes:

[0041] S101, taking a gear shift module including multiple sub-functions as a whole as an operating entity, and adding an event time period to the operating entity;

[0042] S102, placing the pre-processing module and sub-function modules of the input signal of the shift module into the running entity; wherein the sub-function modules at least include an automatic P module, a scheduled shift module, and a factory mode module;

[0043] In one embodiment, the pre-processing module and the sub-function module of the input signal of the shift module are placed in the running entity, including:

[0044] The pre-processing module and sub-functional module of the CAN signal, IO signal or output signal of other modules received by the shift module are placed in the running entity.

[0045] S103, determining the input signal and output signal of the running entity;

[0046] In one embodiment, determining an input signal and an output signal of an operating entity includes:

[0047] The throttle opening, KL15, and brake pedal signal input are used as the CLIENT end of the CS interface.

[0048] In one embodiment, determining an input signal and an output signal of an operating entity includes:

[0050] The output signal of the gear module is used as the sender of the SR interface of other functional modules and CAN system signals.

[0051] S104: standardize the names of the input and output ports of the running entity to match the CAN message names and keep them consistent with the names of other control modules.

[0052] The shift module AUTOSAR software component development method based on Simulink includes: taking a shift module including multiple sub-functions as a whole as a running entity, and adding an event time period to the running entity; placing a pre-processing module of an input signal of the shift module and a sub-function module into the running entity; wherein the sub-function module at least includes an automatic P module, a scheduled shift module, and a factory mode module; determining the input signal and output signal of the running entity; and standardizing the naming of the input port and the output port of the running entity to match the CAN message name and keep it consistent with the naming of other control modules, thereby reducing the workload of Autosar development, improving work efficiency, and simplifying work content.

[0053] In order to explain the above method in detail, an embodiment is used to explain it in detail below.

[0054] In order to reduce workload, improve work efficiency, simplify work content, and facilitate the rapid establishment of the SWC of the shift module, the technical means of this embodiment include: AUTOSAR SWC software component establishment technology, Simulink technology, ISOLAR-A / B software technology; the technical solution is: using AUTOSAR SWC software component establishment technology and Simulink technology to achieve the establishment of the controller shift module SWC software component.

[0055] based on Figure 2 and Figure 3 As shown, the method comprises the following steps:

[0056] (1) Treat the entire shift module as a runnable entity. No matter how many modules the shift module consists of, add an event time period event to this runnable entity. There is no need to create multiple SWCs and runnables.

[0057] (2) Put the pre-processing module of the input signal of the shift module and the sub-function (automatic P, scheduled shift, factory mode, etc.) modules into this runnable. The input signal of the entire runnable is the received CAN signal, IO signal, or the output signal of other modules. It is convenient to find the most original input signal without paying attention to the intermediate processing signal.

[0058] (3) The throttle opening, KL15, and brake pedal signal input are used as the CLIENT end of the CS interface.

[0059] (4) The P, R, N, D gear message signals, other CAN messages and the output signals of other functional modules in the VCU are used as the RECEIVER port of the SR interface, and the output signal of the gear module is used as the Sender of the SR interface of other functional modules and CAN system signals.

[0060] (5) The input and output port naming of this runnable matches the CAN message and is consistent with other modules so that the ports can be connected after being imported into the ISOLAR software.

[0061] This embodiment only needs to establish a shift SWC and a runnable entity to simplify the structure. It is only necessary to clarify the input and output signals of the shift module and put the signal pre-processing into this runnable. The port signal is named in a standardized manner, matching the CAN message name and keeping consistent with the naming of other control modules, which facilitates port connection.

[0062] This embodiment has the following beneficial effects: 1.

Improves the work efficiency of AUTOSAR development. 3. Reduces the labor cost of software development. 4. Conveniently imports ISOLAR software and connects to other modules.
