Effect of Height and Width of Road Humps on Deceleration Performance and Driving Safety

Through the establishment of a five-degree-of-freedom vehicle model, calculating and analyzing the seat vertical acceleration, wheel ground adhesion index and the wheel dynamic load for the car with different speeds that runs over road humps having different height and width, so as to obtain the effect of height and width of the hump on the deceleration performance and driving safety. According to the comparative analysis of the seat acceleration, wheel ground adhesion index and the wheel dynamic load, so as to obtain the best speed limit range of the road hump.
