Embodiment Construction

[0025] Such as figure 2 As shown, the vehicle-mounted control software system strategy code and the underlying code integration method provided by the present invention are based on the Matlab software implementation, and the PWM (pulse width modulation) output is set as an example, including the following steps:

[0026] Write the underlying driver code to realize setting PWM. For example: the function name is "uint8IFL_Pwm_SetPeriodAndDuty(uint16Channel, uint32Period, uint16Duty)

[0027] According to the underlying driver interface, create an S-function in Matlab, and the function name is sfun_dcm21c_pwm;;

[0028] Based on the Matlab package S-function, the subsystem is named pwm_out, and the package parameter pwm_channel is set according to the underlying driver interface of the created subsystem;

[0029] Create a Matlab library file, the Matlab library file contains all the subsystems created in the above steps; add the module pwm_out to the Matlab library file

Abstract

The invention discloses a Matlab-based vehicle control software integration method, comprising the following steps: creating an S-function in Matlab according to the bottom-level drive interface; encapsulating the S-function in the Matlab; creating a subsystem and setting packaging parameters according to the bottom-level drive interface Encapsulate S-function; create Matlab library file, which contains all the subsystems created in the above steps; build a system strategy model in Matlab, and use the above-created subsystem for all models that need to call the underlying software driver; use Matlab RTW function Perform code generation, and use ert_make_rtw_hook.m to control the entire software integration process and generate the final target file. The integration method of the invention can reduce manual code input links, save development costs and improve work efficiency.
