Fig. 1 is a schematic diagram of tire structure;

Fig. 2 is the control flowchart of the control method of the automobile wheel control system;

The marks in the above figures are: 1, non-pneumatic tire; 2, pneumatic tire; 3, wheel hub.

detailed description

The utility model arranges at least one non-inflatable tire 1 and one pneumatic tire 2 on each wheel hub 3 of the automobile. By controlling the inflation status of the pneumatic tire 2, the wheels can meet the needs of different road conditions.

The preferred solution is shown in Figure 1, two air-free tires 2 and four air-free tires 1 are arranged on a wheel hub 3, wherein two air-free tires 1 are located between the two air-free tires 2, and the other two air-free tires 1 are located between the two air-free tires 1. Pneumatic tire 1 outside. In this way, regardless of whether the pneumatic tire 2 is in a working state (whether it is inflated), the normal operation of the vehicle can be guaranteed, and stable and reliable work can be performed to keep the wheel motion balance.

In order to control the inflation status of the pneumatic tire 2 conveniently, each pneumatic tire 2 is connected to the air pump through an independent pipeline, and the connected pipeline is provided with an air release valve, by controlling the air pump and the air release valve, the working condition of the air tire 2 can be controlled .

In addition, there are gaps between the non-pneumatic tires 1 and between the pneumatic tires 2 and the non-pneumatic tires 1. The gaps can ensure the deformation of the tires, provide sufficient cushioning for the vehicle, and protect the tires for easy replacement and installation. tire. The tread pattern of the pneumatic tire 2 is a tire tread pattern for snow or rainy weather, so that the wheel can be adapted to different road conditions. The non-pneumatic tire 1 then has conventional tread patterns.

Based on the above-mentioned tire structure, the utility model designs a tire control system, which is mainly aimed at the control of the pneumatic tire 2. unit for signal and communication units.

The control buttons in the car output control signals to the controller, and the control signals include inflation or deflation of the pneumatic tire 2, and switching between manual control and automatic control; Inflate or deflate; the tire pressure sensor outputs sensing signals to the controller to monitor the tire pressure status of each pneumatic tire 2 in real time, and the controller outputs tire pressure signals to the display to facilitate the driver to know the status of the pneumatic tire 2 in real time; The signal is sent to the controller to let the system "know" whether it is raining or not. The controller is connected to the driving computer at the same time to retrieve the current vehicle speed signal for automatic control; the GPS unit sends the current vehicle position signal to the controller in real time, and the controller communicates The unit communicates with the remote car service center, outputs the geographic location signal, and also receives the control signal of the pneumatic tire 2 at the same time.

The control method based on the vehicle wheel control system includes manual control and automatic control, and manual control and automatic control are switched by buttons;

Manual control is to control the inflation and deflation of the pneumatic tire 2 through the control buttons in the car;

Automatic control:

First priority: The rain sensor receives a rain signal or the vehicle speed reaches a preset threshold, and keeps the pneumatic tire 2 in an inflated state; in this way, when it rains and the vehicle speed is too fast, it will automatically inflate to ensure the friction of the vehicle and improve the safety of the vehicle. sex;

Second priority: the GPS unit uploads the real-time position of the vehicle to the remote car service center through the communication unit, and the remote car service center automatically controls the pneumatic tire 2 to remain inflated or airless according to the road condition signal in the database; The road condition map is pre-stored in the database of the automobile service center, and the appropriate tire usage condition is edited;

The third priority: the speed of the vehicle is lower than the preset threshold, and the pneumatic tire 2 is kept in an airless state, which can ensure that the pneumatic tire 2 is initially in an airless state and reduce driving fuel consumption.

The utility model has been exemplarily described above in conjunction with the accompanying drawings. Obviously, the specific implementation of the utility model is not limited by the above-mentioned methods, as long as various insubstantial improvements are made by adopting the method concept and technical solutions of the utility model, or Directly applying the ideas and technical solutions of the utility model to other occasions without improvement is within the protection scope of the utility model.
