Combined with the correlative parameters of a certain commercial vehicle, the change of brake forces match and the effect on vehicle’s brake stability was analyzed when using hydraulic retarder. In order to avoid the trend of rear axle sideslip, there is a limited brake torque for a commercial vehicle with fixed parameters. Then the state of the commercial vehicle was simulated using MATLAB, obtaining the allowable maximum hydraulic retarder gears at different initial brake speeds. The results indicate that when vehicle’s actual brake forces distribution value is changeless, this method can decrease the trend of rear axle sideslip for two-axle commercial vehicles equipped with hydraulic retarders. |
