Detailed Description
To explain technical contents, structural features, and objects and effects of the technical solutions in detail, the following detailed description is given with reference to the accompanying drawings in conjunction with the embodiments.
Fig. 1 is a schematic structural diagram of a control system 19 for balancing tire pressure of a vehicle according to an embodiment of the present invention. The vehicle comprises at least two tires 10 (only one tire is shown in fig. 1), the control system comprises a tire pressure detecting unit 12, a gas storage unit 13, a tire pressure regulating unit 14 and a control unit 15; the gas storage unit 13 is connected to the hub 11 of each tire 10 via a vent passage 18;
the tire pressure detecting unit 12 is configured to detect the air pressure in the gas storage unit 13 in real time, and send a first signal to the control unit 15 when the air pressure in the gas storage unit 13 satisfies a predetermined condition;
the control unit 15 is configured to receive the first signal and control the tire pressure adjusting unit 14 to adjust the air pressure in the gas storage unit 13 according to the first signal, so that the tire pressures of all the tires are equalized.
In this embodiment, the tire pressure detecting unit 12 may be implemented by an air pressure sensor, and the main sensing elements of the air pressure sensor are a film sensitive to the intensity of the air pressure and a thimble, and a flexible resistor is connected to the air pressure sensor in terms of a circuit. When the pressure of the gas in the gas storage unit to be measured is reduced or increased, the film is deformed to drive the thimble, and the resistance value of the resistor is changed. The resistance of the resistor changes and is received by the data collector via an a/D conversion, which then transmits the result in a suitable form to the control unit.
In this embodiment, the control unit may be implemented by any one of the following components: a general purpose single-or multi-chip processor, a Digital Signal Processor (DSP), an Application Specific Integrated Circuit (ASIC), a Field Programmable Gate Array (FPGA) or other programmable logic device, discrete gate or transistor logic, discrete hardware components, or any combination thereof designed to perform the functions described herein. A general purpose processor may be a microprocessor or any conventional processor, controller, microcontroller, or state machine. A processor may also be implemented as a combination of computing devices, e.g., a combination of a DSP and a microprocessor, a plurality of microprocessors, one or more microprocessors in conjunction with a DSP core, or any other such configuration. In some implementations, certain processes and methods may be performed by circuitry that is specific to a given function. Of course, in other embodiments, the control unit may also be an electronic device including any one of the above components, such as a vehicle-mounted central control system, an upper computer, a mobile terminal, and the like.
In this embodiment, the gas storage unit is a container for storing gas, and the gas storage unit is connected with the hubs of each tire through the ventilation channel, so that the hubs of each tire are interconnected and communicated through the gas storage unit, and the stability of the tire pressure in the driving process of the automobile is ensured. And whether the current tire pressure of each tire is too high or too low can be judged by monitoring the air pressure in the gas storage unit in real time, and the control unit starts the tire pressure adjusting unit to adjust the air pressure in the gas storage unit by sending a first signal to the control unit. The first signal is a signal that triggers adjustment of the gas pressure in the gas storage unit after the gas pressure in the gas storage unit satisfies a predetermined condition. In general, the predetermined may be too high or too low of a gas pressure.
As shown in fig. 2, in the present embodiment, the tire pressure regulating unit includes an inflator 141; the predetermined condition includes determining that the gas pressure in the gas storage unit 13 is less than the gas pressure lower limit value; controlling the tire pressure adjusting unit to adjust the air pressure in the air storage unit so that the tire pressures of all the tires are equalized comprises: and controlling the inflating device to inflate the gas storage unit until the air pressure in the gas storage unit reaches the preset air pressure so as to balance the tire pressures of all the tires. Equalizing the tire pressures of all the tires means that the tire pressures of the respective tires are substantially equivalent to a predetermined air pressure. Because the gas storage units are respectively connected with the hubs of the tires through the ventilation channels, the tire pressure of each tire is always consistent with the air pressure in the gas storage units when each ventilation channel is in an open state, and when the inflation device inflates the gas storage units, the tire pressure of each tire can also rise synchronously. Therefore, when a tire pressure of a certain tire is too low, if the air pressure in the air storage unit is reduced to be lower than the air pressure lower limit value, the control unit can start the inflation device to inflate the air storage unit in time, and further the tire pressure of each tire is improved, so that the tire pressures of all the tires are balanced.
In this embodiment, the inflator is a device for inflating the gas storage unit, and may include a high-pressure gas storage chamber and an automatic inflation switch, where the automatic inflation switch connects the high-pressure gas storage chamber and the gas storage unit. The control unit can control the automatic inflation switch to be turned on, so that the gas in the high-pressure gas storage chamber enters the gas storage unit, and the gas storage unit is inflated. After the inflation, if the air pressure in the air storage unit reaches the preset air pressure, the control unit can stop the air in the high-pressure air storage chamber from entering the air storage unit by controlling the automatic inflation switch to be turned off, so that the inflation device stops continuously inflating the air storage unit. The preset air pressure can be set according to actual needs, and is preferably the safe tire pressure meeting the normal driving state of the vehicle.
In some embodiments, the tire pressure regulating unit includes a deflation device 142; the predetermined condition includes determining that the gas pressure in the gas storage unit is greater than a gas pressure upper limit value; controlling the tire pressure adjusting unit to adjust the air pressure in the air storage unit so that the tire pressures of all the tires are equalized comprises: and controlling the air discharging device to discharge air to the air storage unit until the air pressure in the air storage unit reaches the preset air pressure so as to balance the tire pressures of all the tires. In the present embodiment, equalizing the tire pressures of all the tires means that the tire pressures of the respective tires are substantially equivalent to the predetermined air pressure. Since the gas storage units are respectively connected with the hubs of the tires through the air passages, the tire pressures of the tires 10 and the air pressure in the gas storage units are always consistent when the air passages 18 are all opened, and the tire pressures of the tires are synchronously reduced when the air discharging device discharges the gas in the gas storage units. Therefore, when the tire pressure of a certain tire is too high, if the air pressure of the certain tire is raised to the upper limit value of the air pressure, the control unit can start the air discharging device to discharge air to the air storage unit in time, and then the tire pressure of each tire is reduced, so that the tire pressures of all the tires are balanced.
In the present embodiment, the air bleeding device is a device for bleeding the gas storage unit, and may include a low-pressure air reservoir and an automatic air bleeding switch, which connects the low-pressure air reservoir and the gas storage unit. The control unit can control the opening of the automatic deflation switch, so that the gas in the gas storage unit enters the low-pressure gas storage chamber, and the gas storage unit is deflated. After deflation, if the air pressure in the air storage unit reaches the preset air pressure, the control unit can stop the air storage unit from continuously entering the low-pressure air storage chamber by controlling the closing of the automatic deflation switch, so that the deflation device stops continuously deflating the air storage unit. The preset air pressure can be set according to actual needs, and is preferably the safe tire pressure meeting the normal driving state of the vehicle.
As shown in fig. 2, in some embodiments, a gas sensor 16 is also provided on the vent channel 18 between the gas storage unit 13 and the hub 11 of each tire 10; the gas sensor 16 is used for collecting gas flow information and sending the gas flow information to the control unit; the airflow information includes airflow rate and direction within the ventilation channel. Through still being provided with gas sensor 16 on the air channel 18 between gas storage unit 13 and the wheel hub 11 of each tire 10, can make the control unit learn the current independent tire pressure condition of each tire, if a certain tire takes place flat child or gas leakage phenomenon, just can in time learn through the air current information of gas sensor response, and then take regulation and control measure. For example, when a certain tire is flat, the air flow direction is from the air storage unit to the tire hub, and the air flow detected by the air sensor in unit time is obviously increased.
As shown in fig. 2, a control valve 17 is further provided between the position of the gas sensor 16 and the gas storage unit 13 in the same ventilation channel; the control unit 15 is further configured to control the opening or closing of the control valve on the corresponding ventilation channel according to the received information of the gas flow transmitted by each gas sensor and according to the information of the gas flow transmitted by each gas sensor. The control valve 17 may be an electrically operated valve or a pneumatically operated valve. When the control valve is in an open state, a ventilation channel between the gas storage unit and the tire hub is opened; when the control valve is in the closed state, the air passage between the gas storage unit and the tire hub is closed.
Specifically, in some embodiments, the control unit is configured to control the control valve disposed on the ventilation channel between the hub of a certain tire and the gas storage unit to close when it is determined that a certain tire has an air leakage condition; the occurrence of a flat condition in the tyre is triggered according to the following conditions: the gas flow direction collected in the preset time period by the gas sensor is from the gas storage unit to the tire hub, and the gas flow collected in the preset time period is lower than a preset flow value. Preferably, the control unit is configured to, when it is determined that a certain tire is deflated and another tire is not deflated, close the control valve on the air passage corresponding to the tire in which the air loss request occurs, and simultaneously keep the control valve on the air passage corresponding to the other tire in which the air loss condition does not occur open.
Because the opening or closing of each air passage is independently controlled, when a certain tire leaks air, the control unit can close the control valve on the air passage corresponding to the tire, so that the tire pressure of other tires is kept balanced.

The hubs include a first hub 111, a second hub 112, a third hub 113, and a fourth hub 114. The gas sensors include a first gas sensor 161, a second gas sensor 162, a third gas sensor 163, and a fourth gas sensor 164. The control valve 17 includes a first control valve 171, a second control valve 172, a third control valve 173, and a fourth control valve 174. The vent passages include a first vent passage 181, a second vent passage 182, a third vent passage 183, and a fourth vent passage 184.
The first hub 111 is connected to the gas storage unit 13 through a first vent passage 181, the first gas sensor 161 and the first control valve 171 are sequentially disposed on the first vent passage 181, and the first control valve 171 is disposed between the first gas sensor 161 and the gas storage unit 13.

The third hub 113 is connected to the gas storage unit 13 through a third vent passage 183, a third gas sensor 163 and a third control valve 173 are sequentially disposed on the third vent passage 183, and the third control valve 173 is disposed between the third gas sensor 163 and the gas storage unit 13.
The fourth hub 114 is connected to the gas storage unit 13 through a fourth ventilation passage 184, the fourth gas sensor 164 and the fourth control valve 174 are sequentially disposed on the fourth ventilation passage 184, and the fourth control valve 174 is disposed between the fourth gas sensor 164 and the gas storage unit 13.
Because four tires are correspondingly connected with the same gas storage unit through respective vent channels, the problem of tire burst or air leakage of each tire occurs, the control valve on the corresponding vent channel can be independently controlled, and the tire pressure of other tires without abnormal conditions is not influenced.
