A test device for active anti-rollover control of a bus

Abstract

The invention provides a motor bus active rollover-prevention control test device and belongs to the field of motor bus active safety coefficient tests. The device is characterized in that digital signals of variables such as a bus speed, an acceleration, a suspension displacement are generated by a computer with a virtual motor bus system, and real sensor physical signals are simulated by a D / A conversion circuit through the digital signals, an active rollover-prevention control system collects the real sensor physical signals and makes an active rollover-prevention algorithm decision, the active rollover-prevention control system predicts whether the motor bus has a rollover danger at the next moment according to the driving state of the motor bus, if yes, a control signal of a suspension displacement adjusting device is output, the control signal is converted into a digital signal by an A / D conversion unit, and the digital signal is transmitted to the computer with the virtual motor bus system, so that the virtual execution mechanism is adjusted. By adopting the simulation platform, the active rollover-prevention technology is effectively researched, the risk of directly using an active rollover-prevention control system in a road test is avoided, and the test cost is lowered.

Description

Technical field [0001] The invention relates to the field of active safety of buses, in particular to an active anti-rollover control test device for buses. Background technique [0002] In recent years, my country's transportation industry has developed rapidly. Due to the slow development of the application of active safety technology on buses, the rollover accidents of buses have increased year by year, causing serious property losses and casualties to the country and the people. In the process of studying the active anti-rollover technology of buses, if the developed active anti-rollover control system is directly used in road tests, it will not only lead to a certain degree of danger in the test, but also increase the cost of the test. At present, the research on the active anti-rollover control algorithm of buses has made some progress at home and abroad. The verification of the active anti-rollover control algorithm is only in the software simulation stage, and there ...
