Description

Technical Field

[0001] The present invention relates to the technical field of pneumatic, hydraulic and electronic sensors for passenger vehicles, and in particular to an integrated system for passenger vehicles. Background Art

[0002] Modern passenger vehicles typically include a series of independent pneumatic, hydraulic, and electronic systems. For example, a typical modern passenger vehicle is equipped with a pneumatic shock absorber system that relies on compressed air, a hydraulic brake system that relies on water, and an electronic sensor system. The electronic sensor system, which supports adaptive cruise control or lane assist technology, may become clogged by dirt and dirt on the road and in the environment during use. These systems are not interconnected and operate independently in the electronic and physical space.

[0003] This way of multiple systems running independently will lead to low overall system efficiency:

[0004] On the one hand, there is redundancy between independently operating systems. For example, the air system is equipped with multiple independent air compressors instead of a shared air compressor, which will make the passenger car more complex and larger than necessary to achieve its functions. For example, some existing technologies use a method of injecting high-pressure air to clean sensors. In this case, a separate air compressor is usually considered for the cleaning system, while the air compressor and pressurized air tank equipped with the pneumatic shock absorption system itself are not fully utilized. Equipping multiple air compressors to achieve the functions of multiple systems not only increases the cost of achieving the system functions, but also increases the overall weight of the vehicle.

[0005] If the same air compressor is used to serve multiple different gas systems at the same time, the air pressures used by these pneumatic devices will be different, and frequent flow adjustment of the air compressor will reduce its service life. In addition, the stability of gas operation is poor, which may result in electronic sensors not being effectively cleaned when the cleaning system is working, exposing users to greater driving risks.

[0006] On the other hand, the heat generated by the operation of the air compressor in the pneumatic shock absorption system will dissipate into the environment, while the hydraulic system may need to use an additional heating system to ensure that the liquid in the water tank will not freeze in a cold environment, especially in winter; when the commonly used electronic sensors are too dirty or the sensing parts are blocked by frost, they will fail, but the energy of the air compressor cannot be transmitted to the water tank to provide warm water to clean or defrost the electronic sensors; as a result, the waste heat of the system cannot be fully and effectively utilized, resulting in energy waste. Summary of the Invention

[0007] To this end, the present invention provides an integrated system for a passenger vehicle to address the aforementioned deficiencies in the prior art. More specifically, the present disclosure provides a system for arranging the pneumatic, hydraulic, and electronic sensor components of a passenger vehicle in a more integrated manner, expanding the scope of use of certain components to assist others and enabling heat and other energy generated by one component (which would otherwise be lost to the environment) to be used to assist in the efficient operation of other components. It should be understood that the system and its operating method herein are not limited to passenger vehicles, but can be used in any system utilizing an air compressor, a water tank, and optionally, electronic sensors.

[0008] According to the disclosure described herein, without limiting the disclosure in any way, in an embodiment disclosed herein, the passenger vehicle integrated system includes: an air compressor and a cleaning system.

[0009] The air compressor is connected to the pressurized air tank 1 and the pressurized air tank 2 respectively, and the air compressor, the pressurized air tank 1 and / or the pressurized air tank 2 are connected to the pneumatic shock absorption system;

[0010] The cleaning system includes a water tank, a water pump and at least one nozzle connected in sequence. The nozzle is pneumatically connected to the air compressor, pressurized air tank 1 and / or pressurized air tank 2 and hydraulically connected to the water tank, and is configured so that the gas or liquid sprayed from the nozzle contacts the electronic sensor to clean dirt or defrost / de-ice the surface thereof.

[0011] In some embodiments disclosed herein, a passenger vehicle integrated system includes a controller in electronic communication with at least an air compressor and a water pump, the controller controlling activation of each component separately.

[0012] In some embodiments disclosed herein, the nozzle of the cleaning system is fluidly connected to a water tank, so that when a controller issues an instruction, the liquid in the water tank can flow to the nozzle through a water pump, and the liquid sprayed from the nozzle can be used to remove dirt from electronic sensors or defrost / de-ice them.

[0013] In some embodiments disclosed herein, the nozzle of the cleaning system is pneumatically connected to an air compressor, so that warm air generated by the air compressor can flow to the nozzle under the command of a controller, and the warm air ejected from the nozzle can be used to remove dirt from electronic sensors or to defrost / de-ice them.

[0014] In some embodiments disclosed herein, the pressurized gas tank 2 stores gas at a lower pressure than the pressurized gas tank 1. Pressurized gas tank 2 stores gas at a different pressure than pressurized gas tank 1, allowing two pneumatic systems on a single passenger vehicle that operate at different air pressures to share an air compressor and respectively use gas from two different pressurized gas tanks that are pneumatically connected to the same air compressor. For example, pressurized gas tank 1 can serve a pneumatic shock absorber system on a passenger vehicle at a pressure of 18 bar, while pressurized gas tank 2 can serve a pneumatic seat ventilation system on the same passenger vehicle at a pressure of 5 bar, while using only a single air compressor to fill pressurized gas tanks 1 and 2 with gas.

[0015] In some embodiments disclosed herein, the second and first pressurized gas storage tanks are integrated into a single tank body, the interior of which is divided into a first gas storage chamber and a second gas storage chamber. This integrated gas storage tank combines multiple gas storage chambers, resulting in high space utilization, low cost, and the ability to provide independent, stable gas sources for multiple systems.

[0016] Some embodiments disclosed in the present invention further include:

[0017] a first pressure regulating valve, the first pressure regulating valve being pneumatically connected to at least one of the first pressurized gas storage tank and the second pressurized gas storage tank;

[0018] A second pressure regulating valve is pneumatically connected to at least one of the first and second pressurized gas storage tanks.

[0019] In some embodiments disclosed herein, the first pressure regulating valve allows gas to pass through at a higher pressure than the second pressure regulating valve.

[0020] Pressure regulating valve 1 and pressure regulating valve 2 are both pneumatically connected to a pressurized gas reservoir, such that pressure regulating valve 1 facilitates the flow of gas at a set pressure to a first pneumatic system, and pressure regulating valve 2 facilitates the flow of gas at a different set pressure to a second pneumatic system while utilizing only a single pressurized gas reservoir. For example, pressure regulating valve 1 can serve a pneumatic shock absorber system on a passenger vehicle by only allowing air at a pressure of 18 bar to flow from the pressurized gas reservoir into that system, while pressure regulating valve 2 can serve a pneumatic seat ventilation system on the same passenger vehicle by only allowing air at a pressure of 5 bar to flow into the system, while utilizing a single pressurized gas reservoir.

[0021] Some embodiments disclosed in the present invention further include:

[0022] A gas distribution valve is connected to the air compressor, pressurized gas tank 1 and pressurized gas tank 2. The pressurized gas released from the air compressor, pressurized gas tank 1 and pressurized gas tank 2 can be distributed to the pneumatic shock absorption system, cleaning system or at least one other air and / or water supply system through the gas distribution valve.

[0023] Some embodiments disclosed in the present invention further include:

[0024] A liquid distributing valve is connected to the water pump, and the liquid pumped by the water pump is distributed to the cleaning system or at least one other air and / or water supply system through the liquid distributing valve.

[0025] In some embodiments disclosed herein, an air compressor is thermally connected to a water tank, thereby promoting heat transfer between the air compressor and the water tank. The water tank body is configured to at least partially contact the air compressor casing. The air compressor and water tank are configured such that when the air compressor's air pump operates, heat generated causes the casing to increase in temperature. The air compressor casing, through heat exchange, raises the temperature of the water tank body, which at least partially contacts the casing. The casing exchanges heat with the liquid therein, establishing thermal communication between the air compressor and the liquid.

[0026] In some embodiments disclosed herein, the cleaning system further comprises a heating device, which is disposed between the nozzle and the electronic sensor so that the gas or liquid ejected from the nozzle contacts the heating device.

[0027] The heating device is electrically connected to a controller, which can issue a command to heat the compressed air from the air compressor and eject it from the nozzle. The heated air is used to remove dirt from the electronic sensor or to defrost / de-ice the electronic sensor. The heating device can be any heating device, such as a resistance wire or chip resistor placed behind the electronic sensor.

[0028] In some embodiments disclosed herein, a pressurized gas storage tank and a water pump are thermally connected, thereby promoting heat transfer between the pressurized gas storage tank and the water pump. The water pump is hydraulically connected to the water tank, and the pump housing of the water pump is configured to at least partially contact the tank body of the pressurized gas storage tank. The water pump and the pressurized gas storage tank are configured such that when the water pump is in operation, heat generated by the water pump causes the pump housing to increase in temperature. The water pump housing, through heat exchange, increases the temperature of the tank body of the pressurized gas storage tank, which at least partially contacts the pump housing. Heat is exchanged between the tank body and the gas therein, establishing thermal communication between the water pump and the pressurized gas storage tank.

[0029] In some embodiments disclosed in the present invention, the above-mentioned passenger vehicle integrated system can also be applied to at least one other air supply and / or water supply system in addition to the cleaning system.

[0030] The present invention has the following advantages:

[0031] (1) The present invention arranges the pneumatic, hydraulic, and electronic sensor components of a passenger vehicle in a more integrated manner. By sharing components such as the air compressor and pressurized air storage tank of the pneumatic shock absorption system to coordinate with the cleaning system and other air and / or water supply systems, structural redundancy is reduced, integration is improved, and the weight of the passenger vehicle is reduced. This can improve the operating efficiency of the entire passenger vehicle integrated system and reduce system operating costs.

[0032] (2) On the one hand, the present invention utilizes the hot gas generated during the operation of the air compressor to clean or defrost / de-ice the electronic sensor; on the other hand, through the thermal connection (heat exchange) between the air compressor and the water tank, a hot liquid is formed in the water tank, and the hot gas or liquid is sprayed from the nozzle to the electronic sensor to remove dirt or debris in the environment that hinders the normal operation of the electronic sensor, or to defrost / de-ice the electronic sensor, thereby eliminating or reducing the dependence of the water tank and air compressor on the heating element in cold climates, improving the cleaning efficiency of the electronic sensor and improving the utilization rate of the heat and waste heat generated by the operation of the air compressor;

[0033] (3) The present invention is equipped with two pressurized gas storage tanks that store gases at different pressures, so that two pneumatic systems on a single passenger car that operate at different air pressures can share one air compressor, and a single pneumatic system can also use the gases in two pressurized gas storage tanks with different pressurization values. The use of multiple pressurized gas storage tanks can reduce the frequency of use of the air compressor when multiple systems are used simultaneously, avoid frequent flow adjustment, and improve the service life of the air compressor and the stability of the gas supply operation process; in addition, the use of multiple pressurized gas storage tanks with different pressure ranges to meet the gas needs of different gas-consuming systems can reduce or eliminate the pressure regulation process, shorten the gas response time, and reduce the number of gas pressure regulating valves used, thereby reducing costs; or by equipping two pressure regulating valves that allow gases at different pressures to pass through, this allows only one pressurized gas storage tank to be used in different pneumatic systems, reducing the number of pressurized gas storage tanks used, thereby reducing the manufacturing cost and weight of the passenger car.

DETAILED DESCRIPTION

[0043] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0044] like Figure 1 As shown, the present invention provides an embodiment of a passenger vehicle integrated system. The passenger vehicle integrated system 100 includes an air compressor 110 , an electronic sensor 150 and a cleaning system 140 .

[0045] In an embodiment of the present invention, the cleaning system 140 includes a water tank 130 and at least one nozzle 142a, 142b. The nozzle is pneumatically connected to the air compressor 110 or hydraulically connected to the water tank 130, and is configured so that the gas or liquid ejected from the nozzle contacts the electronic sensor 150, thereby facilitating cleaning and / or defrosting / de-icing the at least one electronic sensor 150. It should be noted that each electronic sensor 150 may have any number of corresponding nozzles depending on the specific circumstances.

[0046] In some embodiments of the present invention, Figure 1As shown, the passenger vehicle integrated system 100 further includes a pressurized gas tank 1 112 and a pressurized gas tank 2 114, both of which are pneumatically connected to the air compressor 110. For example, the pneumatic connection can be achieved by a sealed pipe connected between the two components of the passenger vehicle integrated system 100, or by any other method of transporting the gas without losing it to the environment.

[0047] In some embodiments disclosed herein, the second pressurized gas storage tank 114 and the first pressurized gas storage tank 112 are integrated into a single tank body, the interior of which is divided into a first gas storage chamber and a second gas storage chamber. This integrated gas storage tank combines multiple gas storage chambers, resulting in high space utilization, low cost, and the ability to provide independent, stable gas sources for multiple systems.

[0048] In the embodiment of the present invention, the air compressor 110 can be the air compressor 110 used to supply air to the air spring in the pneumatic shock absorption system 120 provided on the vehicle. In this way, other air-using units on the vehicle and the cleaning system 140 can share a common air intake source, meeting the requirements of lightweighting the vehicle.

[0049] The pneumatic shock absorbing system 120 includes at least one air spring 121a. In the embodiment of the present invention, it includes four air springs 121a, 121b, 121c and 121d (one for each wheel on a standard passenger car). Figure 1 As shown, the four air springs 121a, 121b, 121c and 121d are all connected to the air compressor 110 through the gas distribution valve 116. In some embodiments, the pressurized gas of the air compressor 110 is stored in the pressurized gas tank 112 and is timely delivered to the corresponding air spring through the gas distribution valve 116 to play a role in shock absorption.

[0050] In some embodiments, the second pressurized gas tank 114 may be in pneumatic communication with the nozzles 142a, 142b.

[0051] In some embodiments, the set pressure values ​​of the gas stored in the pressurized gas storage tank 1 112 and the pressurized gas storage tank 2 114 are different.

[0052] Illustratively, the pressure of the gas stored in pressurized gas tank 1 12 is higher than the pressure of the gas stored in pressurized gas tank 2 114. Typically, the pressure of the gas used to clean the electronic sensor 150 is lower than the pressure of the gas in pressurized gas tank 1 112 used in the pneumatic shock absorption system 120.

[0053] This allows two pneumatic systems on a single passenger vehicle that operate at different air pressures to share one air compressor 110 and use gas from two different pressurized air tanks that are pneumatically connected to the same air compressor 110. For example, pressurized air tank 112 can serve the pneumatic shock absorber system 120 on a passenger vehicle at a pressure of 18 bar, while pressurized air tank 2 114 can serve the pneumatic seat ventilation system of the same passenger vehicle at a pressure of 5 bar, while only a single air compressor 110 is used to fill pressurized air tank 1 112 and pressurized air tank 2 114 with gas.

[0054] The use of multiple pressurized gas storage tanks with different pressure ranges can reduce the frequency of use of the air compressor 110 when multiple systems are used simultaneously, avoid frequent flow adjustment, and increase the service life of the air compressor 110 and the stability of the gas supply operation process; in addition, the pressure regulation link can be eliminated or reduced, on the one hand, which can reduce the number of gas pressure regulating valves used and reduce costs; on the other hand, it can also shorten the gas response time.

[0055] In an embodiment of the present invention, a controller 160 is further included that is electrically connected to the air compressor 110. The controller 160 sends instructions to the air compressor 110 to enable the air compressor 110 to deliver compressed gas to the pressurized gas storage tank 1 112 or the pressurized gas storage tank 2 114.

[0056] In an embodiment of the present invention, at least one other air supply and / or water supply system 170 is further included, and the air supply and / or water supply system 170 is pneumatically connected to the air compressor 110, pressurized air tank 1 112 and / or pressurized air tank 2 114, and the air supply and / or water supply system 170 is hydraulically connected to the water tank 130.

[0057] It should be noted that the other air and / or water supply system 170 can be any system on a passenger vehicle that utilizes water or pressurized air to achieve its function. Examples of such air and / or water supply systems 170 include, but are not limited to, another pneumatic shock absorption system, another cleaning system, a seat massage system, or a seat ventilation system. The compressed air provided by the air compressor 110 or the liquid supplied by the water tank 130 can meet the functional requirements of at least one of the other air and / or water supply systems 170.

[0058] In some embodiments of the present invention, the passenger vehicle integrated system further includes a gas distribution valve 116, which is connected to the air compressor 110, the pressurized gas tank 1 112 and the pressurized gas tank 2 114. The gas distribution valve 116 is connected to the pneumatic shock absorption system 120, the cleaning system 140 or at least one other air supply and / or water supply system 170. In an embodiment of the present invention, the pressurized gas released from the air compressor 110, the pressurized gas tank 1 112 and the pressurized gas tank 2 114 can be distributed to the pneumatic shock absorption system 120, the cleaning system 140 or at least one other air supply and / or water supply system 170 through the gas distribution valve 116.

[0059] Gas distribution valve 116 distributes gas from pressurized gas storage tanks at different storage pressures to different systems or devices, meeting multiple gas needs and simplifying gas routing. Controller 160 is also electrically connected to gas distribution valve 116 and sends signals to gas distribution valve 116, causing it to release pressurized gas at the appropriate time.

[0060] In the embodiment of the present invention, the water tank 130 is fluidically connected to the water pump 132 , and the controller 160 is electrically connected to the water pump 132 , so that the controller 160 sends a signal to the water pump 132 .

[0061] In some embodiments of the present invention, the passenger vehicle integrated system further includes a liquid distribution valve 134 , which is connected to the water pump 132 . The liquid distribution valve 134 is used to distribute the liquid pumped from the water pump 132 .

[0062] Controller 160 is electrically connected to liquid dispensing valve 134, which is connected to cleaning system 140 or at least one other air and / or water supply system 170. Controller 160 sends a signal to liquid dispensing valve 134, instructing it to release liquid at an appropriate time. The released liquid is then delivered to cleaning system 140 or other air and / or water supply system 170.

[0063] In some embodiments of the present invention, the air compressor 110 and the water tank 130 are arranged in a heat exchange manner, thereby promoting heat transfer between the air compressor 110 and the water tank 130 .

[0064] Heat transfer can be achieved by:

[0065] (i) The air compressor 110 is spatially distributed close to the water tank 130 (e.g., within 5 mm of each other);

[0066] (ii) securing the air compressor 110 to the water tank 130 by bolting the air compressor 110 and the water tank 130 together so that there is no significant space between them;

[0067] (iii) securing the air compressor 110 to the water tank 130 by welding the two components together so that there is no significant space between them;

[0068] (iv) by making an integrated assembly, the air compressor 110 and the water tank 130 are integrally formed;

[0069] (v) By encapsulating the air compressor 110 and the water tank 130 together with an insulating material such as silicone, the heat generated by the air compressor 110 is retained around the water tank 130, thereby reducing the dissipation of heat into the environment;

[0070] or (vi) any other method that facilitates heat transfer between the air compressor 110 and the water tank 130 .

[0071] In an embodiment of the present invention, the body of the water tank 130 is configured to at least partially contact the casing of the air compressor 110. The air compressor 110 and the water tank 130 are configured so that when the air pump of the air compressor 110 is working, the heat generated will cause the temperature of the casing to rise. The casing of the air compressor 110 increases the temperature of the body of the water tank 130 that at least partially contacts the casing through heat exchange, and the body and the liquid inside it exchange heat, establishing thermal communication between the air compressor 110 and the liquid.

[0072] Heat exchange between air compressor 110 and water tank 130 allows any hot exhaust gas from air compressor 110 to be transferred to water tank 130, effectively heating the water in water tank 130 without requiring a separate heating element. The heated water is then delivered to nozzles 142a and 142b and sprayed toward electronic sensor 150, thereby removing dirt or debris from the environment that could impede the proper functioning of electronic sensor 150 or defrosting / de-icing electronic sensor 150. This heat exchange eliminates or reduces the need for heating elements in water tank 130, particularly in cold climates where water in water tank 130 could freeze and clog the vehicle's hydraulic system. It also effectively utilizes waste heat generated during the operation of air compressor 110, preventing it from being released directly into the atmosphere and wasting energy. It should be noted that the liquid in water tank 130 can be any liquid required by various vehicle systems, and the term "water tank 130" is not intended to limit the liquids that can be used. For example, windshield wiper fluid may be used as the liquid in the water tank 130 .

[0073] During operation, the compressed gas from air compressor 110 also acquires heat. This is because the operation of air compressor 110 raises the ambient temperature around and within air compressor 110. This heated compressed gas can be sprayed from nozzles 142a and 142b toward electronic sensor 150, thereby removing dirt or debris from the environment that could impede proper functioning of electronic sensor 150 or defrosting / de-icing electronic sensor 150. This effectively utilizes the heat generated during operation of air compressor 110 and eliminates or reduces the reliance on heating elements for the gas in air compressor 110. In cold climates, heating elements are necessary, requiring more energy than in the present embodiment to achieve the desired effect.

[0074] Now special reference Figure 2 , showing different embodiments of the passenger vehicle integrated system 100. The passenger vehicle integrated system 100 further includes a first pressure regulating valve 118 and a second pressure regulating valve 119. The first pressure regulating valve 118 is in pneumatic communication with at least one of the first pressurized gas tank 112 and the second pressurized gas tank 114; the second pressure regulating valve 119 is in pneumatic communication with at least one of the first pressurized gas tank 112 and the second pressurized gas tank 114.

[0075] In this embodiment of the present invention, pressure regulating valve 118 is pneumatically connected to gas distribution valve 116 and cleaning system 140; pressure regulating valve 2 119 is pneumatically connected to gas distribution valve 116 and at least one other gas and / or water supply system 170. Pressure regulating valve 118 only allows gas with a specific maximum pressure to be released into cleaning system 140. Pressure regulating valve 2 119 only allows gas with a specific maximum pressure different from the maximum pressure allowed by pressure regulating valve 118 to be released into one of the other gas and / or water supply systems 170.

[0076] In an embodiment of the present invention, the pressure regulating valve 118 allows gas to pass through at a higher pressure than the pressure regulating valve 2 119. For example, the pressure regulating valve 118 can serve the pneumatic shock absorption system 120 on a passenger car by only allowing air with a pressure of 18 bar to flow from the pressurized gas tank 112 into the system, while the pressure regulating valve 2 119 can serve the pneumatic seat ventilation system of the same passenger car by only allowing air with a pressure of 5 bar to flow into the system. This will allow the use of only a single pressurized gas tank 112 to achieve multiple pressures in different pneumatic related systems, rather than increasing the use of pressurized gas tanks 2 114 (such as Figure 1 This reduces the number of pressurized gas tanks used, thereby reducing manufacturing costs and the weight of the passenger vehicle.

[0077] It should also be understood that multiple pressurized gas tanks (such as Figure 1 Example in ) and Figure 2In the present embodiment, a plurality of pressure regulating valves are used in combination (not shown in the figure).

[0078] In an embodiment of the present invention, the motor driving the air compressor 110 is configured as a brushless motor with adjustable speed and variable flow rate.

[0079] Now a special reference Figure 3 , shows different embodiments of a passenger vehicle integrated system 100. The passenger vehicle integrated system 100 further includes a heating device, which can make the liquid sprayed to the electronic sensor 150 have a higher temperature.

[0080] The heating device can be set up in the following ways:

[0081] (i) the heating device is disposed between the nozzles 142a, 142b and the electronic sensor 150 so that the gas or liquid ejected from the nozzles contacts the heating device; or

[0082] (ii) the heating device is in thermal communication with the electronic sensor 150; or

[0083] (iii) The heating device is in thermal communication with the nozzle.

[0084] In the embodiment of the present invention, the heating device is at least one resistance wire 190a placed between the nozzle 142a and the electronic sensor 150, and at least one resistance wire 190b placed between the nozzle 142b and the electronic sensor 150. The resistance wire 190a and the resistance wire 190b are configured to provide a heat source, so that any gas or liquid leaving the nozzles 142a and 142b is heated by the resistance wire on the way to the electronic sensor 150.

[0085] The resistance wires can be powered directly by the battery or engine power of the passenger vehicle, or can be controlled by the controller 160 so that when the electronic sensor 150 becomes dirty or frosted / iced, the controller 160 sends a heating signal to the resistance wires 190a, 190b. This provides alternative or supplemental heat to the gas or liquid cleaning agent when it reaches the electronic sensor 150.

[0086] It should be noted that, depending on the actual application, each nozzle 142a, 142b may have more than one associated resistance wire 190a, 190b or no resistance wire at all.

[0087] In some embodiments, the resistance wires 190 a and 190 b may be disposed very close to the electronic sensor 150 (not shown in the figures) so as to directly provide heat to the surface of the electronic sensor 150 .

[0088] Alternatively, the resistance wires 190a and 190b serving as heating devices may also be chip resistors, for example formed into a geometric shape with a larger surface area, so as to better distribute heat to the gas or liquid cleaning agent or directly to the electronic sensor 150 as required.

[0089] It should be noted that the advantages of providing at least the resistance wires 190 a and 190 b do not require that the air compressor 110 be thermally connected to the water tank 130 .

[0090] refer to Figures 4a-4c , shows a passenger vehicle and provides an example of a passenger vehicle integrated system 100 within a passenger vehicle 200 to demonstrate how the various functions of the passenger vehicle integrated system 100 are implemented. As can be seen from the figure, the passenger vehicle 200 has an instrument display 210. The driver or passenger can use the instrument display 210 to perform various functions (e.g., turning the radio on and off, adjusting the temperature settings, checking the fuel tank level, etc.). The passenger vehicle 200 also has at least one headlight 220, which is turned on in this embodiment.

[0091] The passenger car 200 includes the passenger car integrated system 100 described in any of the above embodiments, and its air compressor 110 and water tank 130 are in a heat exchange state as described in the above embodiments. The difference is that in this embodiment:

[0092] The pressurized gas storage tank 112 storing the heat generated during the operation of the air compressor 110 and the water pump 132 are also thermally connected, so that the heat generated during the operation of the water pump 132 can keep the gas in the pressurized gas storage tank 112 at a temperature higher than the ambient temperature, or further heat the gas in the pressurized gas storage tank 112. The thermal connection between the pressurized gas storage tank 112 and the water pump 132 can be achieved by connecting to the heat exchanger 112. Figure 1 The air compressor 110 and the water tank 130 are implemented in the same or similar manner as described above.

[0093] In this embodiment, the gas distribution valve 116 and the liquid distribution valve 134 are also in thermal communication to help reduce heat loss as the gas and liquid are transferred from one location to the next within the passenger vehicle integrated system 100 .

[0094] By keeping the heated gas and liquid in close proximity, the ambient temperature near the gas and liquid increases, slowing the rate of heat transfer to the environment. This is also true for the lines through which the gas and liquid pass in the passenger vehicle integrated system 100.

[0095] For example, if warm water is flowing from the water tank 130 through the vehicle integrated system 100 to the nozzle 142 a, and warm air is flowing from the pressurized gas tank 112 through the vehicle integrated system 100 to the nozzle 142 a (or any other part of the vehicle integrated system 100), by making the exteriors of the two lines through which the warm water and warm air pass contact each other, at least a portion of the surface area in each line will be higher than the ambient temperature, and heat retention in each line will be promoted by reducing the surface area in each line through which heat can be transferred to the ambient air by convection. In other words, the lines carrying the hot gas and the lines carrying the hot liquid should be placed in contact with each other as much as possible.

[0096] In other embodiments, even if the two pipelines are not in contact but are just very close together (e.g., 3 mm apart), each pipeline may heat the ambient air so that the ambient air over at least a portion of the surface area of ​​each pipeline is hotter than the rest of the ambient air from the environment, which will slow down the process of heat dissipation to the ambient air by convection, thereby reducing heat loss.

[0097] Passenger vehicle 200 also includes electronic sensors 150, which, in this embodiment, facilitate adaptive cruise control. Electronic sensors 150 emit signals to the environment. If any signals are returned, they transmit this information to controller 160. If there is a problem with adaptive cruise control, controller 160 can instruct the vehicle to slow down. The air compressor 110, water pump 132, gas distribution valve 116, liquid distribution valve 134, instrument display 210, headlights 220, and electronic sensors 150 all electronically communicate with controller 160. Passenger vehicle integrated system 100 also includes at least one nozzle 142a. In this embodiment, nozzle 142a is configured so that the gas and liquid ejected from nozzle 142a come into contact with the portion of electronic sensor 150 that transmits and receives signals.

[0098] Figure 4a A normally operating passenger vehicle 200 is shown, including a normally operating electronic sensor 150 .

[0099] Figure 4b A passenger vehicle 200 is shown in which an electronic sensor 150 malfunctions due to accumulation of dirt 230 at the location where the electronic sensor 150 transmits and receives signals. The dirt 230 may be dirt from the road, mud from the road, rainwater from rain, snow caked on the exterior of the electronic sensor, accumulation of ice or frost, lubricant spilled from other locations of the passenger vehicle 200, or any other foreign matter or substance adhering to the electronic sensor 150. This dirt 230 may cause the electronic sensor 150 to malfunction in transmitting or receiving signals, which may result in the passenger vehicle 200 failing to slow down in time when approaching a vehicle or object while the adaptive cruise control function is engaged.

[0100] Figure 4c The gas from the pressurized gas tank or the liquid from the water tank 130 is shown to be ejected from the nozzle 142a and contact the surface of the electronic sensor 150 to remove the dirt 230. Once the above functions are achieved, the passenger car 200 will return to Figure 4a The state of the embodiment in FIG.

[0101] Controller 160 may be a shared control unit for passenger vehicle 200 that controls the operation of any electronic component of the vehicle (such as a radio or air conditioning) or any microcontroller or microprocessor. For example, controller 160 may be located in a passenger's mobile phone and communicate the status of passenger vehicle integrated system 100 via wireless communication technology, as well as communicate with any actuators or other controllers configured in passenger vehicle 200 as needed. This allows notifications to be sent to the passenger's mobile phone so that the passenger can decide whether to activate certain functions of passenger vehicle integrated system 100.

[0102] Furthermore, the controller 160 may be provided in each component of the passenger vehicle integrated system 100, enabling the controller network to operate in series to drive the components to operate at a given time, monitor the temperature of each component, monitor the normal operation or failure status of each component, and achieve precise control of the controlled object or any other desired function. The controller 160 functions to drive the actuators of the passenger vehicle 200 or the passenger vehicle integrated system 100 based on the user's wishes (for example, if the user feels that the interior of the passenger vehicle 200 is too hot, the user can instruct the temperature control system to lower the ambient temperature through the controller), or automatically take countermeasures when a system failure occurs (for example, receiving a fault message from the adaptive cruise control system and automatically activating the cleaning system 140 to remove dirt 230 from the adaptive cruise control system's electronic sensor 150).

[0103] Although the present invention has been described in detail above using general descriptions and specific embodiments, it will be apparent to those skilled in the art that modifications and improvements may be made thereto. Therefore, such modifications and improvements, without departing from the spirit of the present invention, are intended to be within the scope of protection claimed herein.
