Method for preventing highway weighing charge error

The invention discloses a method for preventing highway weighing charge error. According to the method, vehicle driving routes are acquired by a range finding sensor so that using "s"-shaped driving tracks, changing the vehicle center of gravity and reducing weight of the vehicle can be prevented. According to the method, driving speed of the charge measurement process is acquired in real time so that the situation that the weight borne by the wheel axle and the position of the center of gravity are changed by the vehicle though multiple times of braking and the weight is reduced can be prevented. Multiple conventional weighing charge escape modes are detected so that the phenomenon of weighing charge error can be avoided. 本发明公开了种防止高速公路称重收费误差的方法，采用测距传感器采集车辆行驶路线，防止车辆采用"s"形的轨迹行驶，改变车辆重心，减低重量的方法；本发明实时采集收费计量过程中的行驶速度，防止车辆通过多次制动改变轮轴所承受的重量和重心位置，减低重量的方法。本发明对多种常规称重逃费方式进行检测，避免了称重收费误差的现象发生。
