Method, device and vehicle for controlling vehicle overload

Abstract

The invention provides a method and device controlling vehicle overload and a vehicle, and belongs to the technical field of vehicles. The device comprises an alarm device, distance sensors, travel switches, time relays and a central control unit; the alarm device is arranged on the vehicle; each distance sensor is arranged on one suspension of the vehicle and used for measuring the distance value between the suspension where the distance sensor is located and a vehicle floor; each travel switch is arranged on one suspension of the vehicle and is turned off when the distance value measured by the corresponding distance sensor is smaller than a first threshold value; each time relay is connected with one travel switch and used for keeping the turn-off time of the corresponding travel switch; the central control unit is used for controlling the alarm device to give an alarm when the timekeeping time of one or more time relays is larger than a second threshold value. By means of the technical scheme, vehicle overload can be avoided.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a method, a device and an automobile for controlling vehicle overloading. Background technique [0002] Overloading is very prevalent in the current automobile transportation process, causing a lot of damage: First, the damage to the road is serious, and the road surface bearing capacity of the design of the road has a certain standard. If a truck is overloaded, the unit pressure of each wheel on the road surface will also increase, exceeding the normal bearing capacity of the road surface, causing damage to the road surface, and shortening the life of the road. A 10% overloaded truck will increase the damage to the road by 40%. twice as many vehicles travel once, which is equivalent to 16 times of non-overrun vehicles, which affects public transportation; second, the lower the safety, the easier it is to cause brake failure in an emergency, causing traffic accidents, causing...

Problems solved by technology

If a truck is overloaded, the unit pressure of each wheel on the road surface will also increase, exceeding the normal bearing capacity of the road surface, causing damage to the road surface, and shortening the life of the road. A 10% overloaded truck will increase the damage to the road by 40%. twice as many vehicles travel once, which is equivalent to 16 times of non-overrun vehicles, which affects public transportation; second, the lower the safety, the easier it is to cause brake failure in an emergency, causing traffic accidents, causing damage to people, society, and property Serious damage; the third is the impact of auto parts. When the car is overloaded, it is easy to cause the front wheel to blow out, which will often increase the load on the tire and cause the wheel to deform. Especially in the case of fast speed, the front wheel is prone to blowout , which is extremely harmful, because the front wheels are steering wheels, and the rolling radii of the two wheels after a blowout are different, which will cause the car to drive immediately to the side of the blown tire, often causing major traffic accidents
