Rail wheel squeal on curves in rail track is a source of potential noise annoyance to residents adjacent to rail lines. For one private rail freight operator, wheel squeal was causing repeated complaints from neighbours. Wheel squeal can be caused by the wheel-tyre to rail-top interaction and the wheel flange interaction with the gauge face of the rail (more like a screech). This paper describe...

This paper presents a process for the estimation of tire-road forces, vehicle sideslip angle and wheel cornering stiffness. The method uses measurements (yaw rate, longitudinal/lateral accelerations, steering angle and angular wheel velocities) only from sensors which can be integrated or have already been integrated in modern cars. The estimation process is based on two blocks in series: the f...

Despite the widespread availability of airbags and a belt use rate of over 85%, U.S. drivers involved in crashes continue to be at risk of serious thoracic injury. One hypothesis is that this risk may be due to the lack of airbag deployment or the airbag ‘bottoming-out’ in some cases. The objective of this study is to determine the incidence and thoracic injury risk of direct steering wheel con...

Automation can help us to reduce the number of crashes on our roads. Through research it is identified that 94 percent accidents occur are because driver behavior or error as a factor and self-driving vehicles error. High levels automation have potential risky dangerous prevent accidents. The main aim convert manual operated steering vehicle into fully autonomous steering. objective Steering Co...

To improve the overall performance of four-wheel steering vehicles under different working conditions and solve problem unbalanced comprehensive control effect a single controller, multi-mode optimal decision system is proposed based on linear 2-DOF dynamic model vehicle, which can make vehicle have better conditions. The composed multiple controllers, in self-tuning dual yaw rate feedback cont...

This paper explores the possibility of combining solid state accelerometers with a low resolution position sensor to provide clean estimates of automobile handwheel position, velocity and acceleration for use in force feedback. Typically determining the acceleration and velocity of the handwheel requires differentiating a position sensor such as an encoder or potentiometer. Unless expensive hig...
