The invention relates to the technical field of vehicles, and particularly discloses a dumper weighing method, a dumper weighing system and a dumper, and the dumper weighing system comprises a suspension pressure sensor for sending load change signals of a front suspension and a rear suspension of the dumper to a whole vehicle controller; the dumper weighing method comprises the steps that a K1 value, a b1 value, a K2 value and a b2 value of a dumper are calibrated under the no-load condition and the preset load condition respectively; the current value output by the suspension pressure sensor under the load condition is recorded, the current value of the front suspension is I front, and the current value of the rear suspension is I rear; the bearing weight M is equal to K1 * I < front > + b1 + K2 * I < rear > + b2-r; when each coefficient of the bearing weight M is calibrated, the weight of the measured vehicle is G when the vehicle is in a no-load state, and after each coefficient of the bearing weight M is calibrated, when the vehicle is in a no-load state, r = K1 * I < front > + b1 + K2 * I < rear > + b2-G. When the method is used for weighing, the suspension pressure sensor outputs the current I < front > and the current I < rear > of the front suspension effect and the rear suspension effect, the real-time bearing weight of the dumper can be calculated according to the formula M = K1 * I < front > + b1 + K2 * I < rear > + b2-r, and the situation that the whole dumper runs abnormally due to overload can be avoided.
本发明涉及车辆技术领域,具体公开了自卸车称重方法、自卸车称重系统及自卸车,自卸车称重系统包括将自卸车前悬挂和后悬挂的负载变化的信号发送至整车控制器的悬挂压力传感器,自卸车称重方法包括自卸车分别在空载和预设负载下,标定K1值、b1值、K2值和b2值;记录负载情况下悬挂压力传感器输出的电流值,前悬挂的电流值为I前,后悬挂的电流值为I后;承载重量M=K1*I前+b1+K2*I后+b2‑r;承载重量M的各系数标定时,测量车辆空载时重量为G,承载重量M的各系数标定后,车辆空载时,r=K1*I前+b1+K2*I后+b2‑G。使用该方法称重,悬挂压力传感器实施输出前悬挂和后悬挂作用的电流I前和I后,通过M=K1*I前+b1+K2*I后+b2‑r,便可计算出自卸车的实时承载重量,可以避免超载导致整车运行异常。
