Control device and method for actively limiting overload of vehicle

Abstract

The invention relates to a control device and method for actively limiting overload of a vehicle. The control device comprises a piston seat, a piston rod which penetrates through the piston seat and is connected with the piston seat, an air inlet and an air outlet, wherein the air inlet and the air outlet communicate with the piston seat. Pressure switches are arranged at the two ends of the piston rod through switch seats correspondingly. A first sensor is further arranged at one end of the piston rod and connected with the corresponding pressure switch in a contact mode. A second sensor is arranged in the piston seat. The air inlet and the air outlet are connected with air valves through pipelines correspondingly. The air valves are further connected with a vehicle brake air inlet. The control device and method can effectively prevent the overload condition of the vehicle, once the overload condition of the vehicle occurs, the vehicle cannot be started, and the purpose of limiting goods overload of the vehicle can be effectively achieved. Moreover, the control device has a dismounting-preventing function, and the situation that traffic accidents are caused by overload can be better avoided.

Description

technical field [0001] The invention relates to the technical field of vehicle safety, in particular to a control device for actively limiting vehicle overload and a control method thereof. Background technique [0002] At present, in order to achieve the highest benefit generated in the transportation process, the trucks at home and abroad are basically seriously overloaded. The danger of overloading trucks is very serious, speeding up the destruction of road facilities and increasing road maintenance costs. shorten the service life of roads. According to expert analysis, the increase in vehicle overweight and its damage to the road surface are geometrically increasing. Trucks that exceed the limit by 10% will increase road damage by 40%. A vehicle that exceeds the limit by 2 times travels once, and the damage to the road is equivalent to that of a vehicle that does not exceed the limit for 16 times. For a 36-ton over-limit vehicle, the damage to the road is equivalent t...

AI Technical Summary

Problems solved by technology

A vehicle that exceeds the limit by 2 times travels once, and the damage to the road is equivalent to that of a vehicle that does not exceed the limit for 16 times. For a 36-ton over-limit vehicle, the damage to the road is equivalent to that of 9,600 cars with a weight of 1.8 tons. For the damage of roads, drivers and car owners will pay 100 yuan for road damage for every 1 yuan profit from over-limit transportation.
