Vehicle control system simulation testing method and system

Abstract

The invention discloses a vehicle control system simulation testing method and system. The vehicle control system simulation testing method comprises the steps that launching vehicle parameters are collected, a launching vehicle mathematical model comprising a testing unit, a sensing unit and an executing unit is established according to the collected launching vehicle parameters, and simulation testing software is written for the launching vehicle mathematical model; the simulation testing software is started, the testing unit receives electromagnetic valve control instructions sent by an external main control unit, the electromagnetic valve control instructions are determined to be effective, the operation amount corresponding to the electromagnetic valve control instructions is calculated and stored, and calculated operation amount information is output; the main control unit generates operation control instructions according to the received operation amount information, a presser operation amount threshold and the fact whether in-place indication information output by the sensing unit is received or not and outputs the operation control instructions; the testing unit controls the executing unit to conduct testing operation according to the received operation control instructions. Through the application of the vehicle control system simulation testing method and system, the testing cost can be lowered, and the time needed for testing can be shortened.

Description

technical field [0001] The invention relates to computer simulation and testing technology, in particular to a vehicle control system simulation testing method and system. Background technique [0002] The vehicle control system of the launch vehicle is used to control the transmission vehicle in the launch vehicle according to the instructions issued by the operating technician through the host computer, for example, the general unit (the general electronic control unit that realizes the signal acquisition and control drive of the vehicle control system), stepping motor and other equipment. The hydraulic valve, solenoid valve and other equipment are controlled, and the judgment and adjustment are made according to the signals collected by the sensors arranged on the launch vehicle, so that the launch vehicle is controlled to complete the process of extending the legs of the launch vehicle and the launch of the launch tube within the launch preparation time. Vertical process...

Problems solved by technology

[0005] It can be seen from the above that although the existing vehicle control system simulation test system can ensure the verification of the functions of each device in the launch vehicle, it needs to purchase hardware to build a test platform. The test cost is high and the test takes a long time, correspondingly prolonging The time for research and development or improvement of the launch vehicle based on the test results; further, the construction progress cannot be guaranteed by purchasing hardware to build a simulation test system for the vehicle control system; The function verification of each device in the launch vehicle under normal conditions cannot be performed by injecting faults into the function verification of each device under abnormal conditions, so it is impossible to comprehensively and objectively analyze and confirm the various indicators of the launch vehicle
