โœฆ Synopsis

This paper describes the stability of a tractor-semitrailer combination while braking. We first constructed nonlinear equations of motion for articulated vehicles with 8 degrees of freedom. Secondly, a simulation study was carried out to model vehicle performance in realistic situations. Jackknifing was recreated by simulation under conditions of traveling down a longitudinal road gradient. A study of the load rate of each tire showed that our model accurately describes the mechanism of jackknifing as well as the motion of limit performance conditions. Finally, the relationship between articulated vehicle, road gradient and limit performance is shown.

Nowadays we are discussing a vehicle stability control system which freely controls the braking force of each wheel to apply the yaw moment and decelerate the vehicle. The system drastically improves the vehicle cornering performance and stabilizes the vehicle behaviour in its critical area. This pa

BDC strategy, which controls rear wheel brake pressures based upon wheel slip ratios, was developed. The effects of BDC were confirmed by actual vehicle tests using a hydraulic brake actuator. Vehicle deceleration was improved independently of loading conditions and vehicle stability while braking i

The aerodynamic influence of a passing vehicle on the motion stability of other vehicles is discussed. According to the results of wind tunnel tests and actual car tests, it is found that the interference phenomenon can be treated as a quasi-steady problem when relative speed is small. The influence
