Embodiment Construction

[0009] Such as figure 1 As shown, the method for configuring the bottom drive and I / O modules in the development of the vehicle control system includes the following steps:

[0010] (3) After obtaining the digital and analog input signals, set the registers of the control chip according to the relevant information of the configuration file, and map the input signals to the I / O structured variables of the application layer;

[0011] (4) When the application layer outputs the application layer output signal, map the application layer output signal to the I / O structural variable of the application layer, set the register of the control chip according to the relevant information of the configuration file, and then give the output digital quantity.

[0012] Since the configuration file is used and the signal is mapped to the I / O structural variable of the application layer, the universality, portability and modular programming of the bottom driver and I / O module of the vehicle cont...

Abstract

The invention discloses a method for configuring a bottom driver and an I / O module in vehicle control system development. The method realizes universality, transportability and modularization programming of the bottom driver and the I / O module of a vehicle control system, improves development efficiency of the vehicle control system, shortens the development cycle, and lowers development risks and cost. The method comprises the following steps: (1) after a digital quantity input signal and an analog quantity input signal are acquired, a register of a control chip is set according to relevant information of a configuration file, and the input signals are mapped to an I / O structuralization variable of an application layer; (2) when the application layer outputs an application layer output signal, the application layer output signal is mapped to the I / O structuralization variable of the application layer, the register of the control chip is set according to the relevant information of the configuration file, and then an output digital quantity is provided.

Description

technical field [0001] The invention belongs to the technical field of development of a vehicle control system, and in particular relates to a method for configuring a bottom drive and an I / O module in the development of a vehicle control system. Background technique [0002] In the development process of the vehicle control system, every time a vehicle controller or model is developed, the underlying driver and I / O control module of the controller must be rewritten. The code portability is poor, repetitive development work, and efficiency low. Contents of the invention [0003] In order to overcome the defects of the prior art, the technical problem to be solved in the present invention is to provide a method for configuring the bottom drive and I / O modules in the development of the vehicle control system, which realizes the bottom drive and I / O modules of the vehicle control system. The versatility, portability and modular programming can improve the development efficie...
