Embodiment Construction

[0020] In order to better understand the present invention, the present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0021] Such as figure 1 As shown, the test system includes air brake system test bench, real-time simulation platform dSPACE real-time simulation system, software system Matlab / ControlDesk and signal processing system. The system test bench carries out data communication, and the software system Matlab / ControlDesk carries out data communication with the real-time simulation platform dSPACE real-time simulation system based on the host computer with the data line as the medium.

[0022] Pneumatic circuits such as figure 2 As shown, the functions of conventional braking and emergency braking are retained, and differential braking operation can be realized. The working process is as follows: the air source device 1 works under electric drive to generate compressed air with a certain pressure value, and...

Abstract

The present invention proposes a hardware-in-the-loop test system and test method for air pressure braking performance of commercial vehicles, including an air pressure brake system test bench, a real-time simulation platform, a software system, and a signal processing system, wherein the real-time simulation platform passes sensors and a signal processing system Carry out data communication with the pneumatic brake system test bench, the software system is based on the upper computer and uses the data line as the medium to carry out data communication with the real-time simulation platform, and realizes the hardware-in-the-loop test of the pneumatic brake performance. Insufficient versatility in air brake performance testing.

Description

technical field [0001] The invention belongs to the technical field of hardware-in-the-loop simulation tests, and in particular relates to a hardware-in-the-loop test system and test method for air pressure braking performance of commercial vehicles. Background technique [0002] With the development of social economy, the proportion of commercial vehicles in transportation is increasing, and people's requirements for the safety performance of commercial vehicles are also getting higher and higher. Rear-end collisions caused by insufficient braking distance, longitudinal collisions caused by wheel locking and loss of steering ability, tail flicking or rushing off the road caused by tire sideslips, etc. are the main safety accidents of commercial vehicles. These safety accidents are related to the air pressure of commercial vehicles Insufficient mobility. As an important component of the commercial vehicle chassis system, the air brake system plays a very important role in t...
