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

Embodiment 1

[0049] This embodiment provides a device for controlling vehicle overloading, which is applied to automobiles, and the device includes:

[0050] The alarm set on the car;

[0051] Distance sensors respectively arranged on each suspension of the automobile are used to measure the distance between the suspension and the corresponding automobile floor;

[0052] A travel switch respectively arranged on each suspension of the automobile is used to close when the distance value measured by the corresponding distance sensor is less than the first threshold;

[0053] A time relay connected to each travel switch is used to time the time when the corresponding travel switch is closed;

[0054] The central controller is used to control the alarm to give an alarm when the timing time of one or more time relays is greater than the second threshold.

[0055] In this embodiment, the distance sensor is used to measure the distance between the suspension and the corresponding vehicle floor. ...

Embodiment 2

[0080] This embodiment also provides a vehicle, including the device for controlling vehicle overloading as described above.

Embodiment 3

[0082] This embodiment also provides a method for controlling vehicle overloading, which is applied to the above-mentioned automobile, and the method includes:

[0083] Use the distance sensor to measure the distance between the suspension and the corresponding car floor;

[0084] Turn off the corresponding travel switch when the distance value measured by the distance sensor is less than the first threshold;

[0085] Time the time when the travel switch is closed;

[0086] When the timing time of one or more time relays is greater than the second threshold, the alarm is controlled to give an alarm.

[0087] Further, the method also includes:

[0088] When the timing time of more than three time relays is greater than the second threshold, the vehicle power supply and the vehicle engine control system are cut off, so that the vehicle cannot be started.

[0089] In this embodiment, the distance sensor is used to measure the distance between the suspension and the correspondi...

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...
