WEIGHT MEASURING DEVICE FOR VEHICLE AND WEIGHT MEASURING METHOD THEREOF

摘要

PURPOSE: A weight measuring device for a vehicle and a weight measuring method thereof are provided to measure the actual weight of axle by compensating a characteristic value according to the load and temperature of an air suspension. CONSTITUTION: A weight measuring device for a vehicle comprises a pressure sensing member(100), a characteristic value providing part(200), a temperature sensor(300), a mass calculation controller(400) and a display member(500). The shafts are formed on the pressure sensing member along a car body frame. The characteristic value providing part offers the characteristic value of each air suspension according to the load and temperature. The temperature sensor measures temperature. The display member is transmitted the signal of the mass calculation controller and indicates the total weight. The pressure sensing member is respectively included in the air input site and exhaust region of each air suspension in order to measure pressure.
