Problems solved by technology

[0002] The current vehicle stability control research is mainly carried out through vehicle dynamics simulation and real vehicle test. Vehicle dynamics simulation systems are generally based on simplified vehicle dynamics models. The rationality and accuracy of simplification affect the simulation system. The performance of the simulation research is often quite different from the actual vehicle test; the disadvantages of the real vehicle test are high cost, long cycle, and greater risk.

Abstract

The invention discloses an automotive stability control safety testing system. The testing system is composed of three parts of a traction rod, a transverse swing link and a vehicle component. The two ends of the traction rod are respectively connected to a fixed shaft and the transverse swing link by pin shafts, the transverse swing link is supported by a five-wheeled instrument. The tension rods of a front wheel and a rear wheel respectively pass through the horizontal holes of vertical pin shafts connected with the transverse swing link, and a limiting spring is located among the tension rods and the vertical pin shafts for limiting the overlarge extension amount of the tension rods. The tension rods of the front and rear wheels are connected to a vehicle clamping device vertically and fixedly through the vertical pin shafts, and the vehicle clamping device is fixedly connected to the vehicle. The relative motion relationship and the stress relationship among the traction rod, the transverse swing link and the vehicle component are determined according to an angular displacement sensor, a linear displacement sensor, and the measurement parameters of the tension gauges of the front and rear wheels among the traction rod, the transverse swing link and the vehicle component. The mass centre of the vehicle and the slip angle of each wheel can be measured by the front wheel steering angle, and the effect for controlling the whole vehicle motion can be obtained by adjusting the side force of the whole vehicle, the transverse swing link torque and the tyre ground acting force through the whole vehicle centrifugal force.

Description

technical field [0001] The invention relates to an actual vehicle test system for automobile stability control. Automobile stability control is an important aspect of automobile active safety research, and the measurement of the actual vehicle stability control test is relatively difficult and dangerous. A safe, convenient and repeatable test system will contribute to the research in this field. The invention proposes a safety test measurement method for automobile stability control and designs its test system. Background technique [0002] The current vehicle stability control research is mainly carried out through vehicle dynamics simulation and real vehicle test. Vehicle dynamics simulation systems are generally based on simplified vehicle dynamics models. The rationality and accuracy of simplification affect the simulation system. The performance of the simulation research is often quite different from that of the real vehicle test; the disadvantages of the real vehicle ...
