Description

Technical Field

[0001] This utility model relates to the field of pneumatic, hydraulic and electronic sensor technology for passenger vehicles, and specifically to an integrated system for passenger vehicles. Background Technology

[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 damping system that relies on compressed air, a hydraulic braking system that relies on water, and an electronic sensor system. This electronic sensor system can work in conjunction with adaptive cruise control or lane-keeping assist technology; however, these electronic sensors may become clogged with dirt and grime from the road and environment during use. These systems are independent of each other and operate independently in both electronic and physical spaces.

[0003] This method of multiple systems operating independently leads to low overall system efficiency.

[0004] On the one hand, there is redundancy between the independently operating systems. For example, the air system is equipped with multiple air compressors that work separately instead of sharing a single air compressor. This will make the passenger car more complex and larger than the necessary structure to achieve its function. For example, some existing technologies use high-pressure air jets to clean sensors. In this case, it is usually considered to equip the cleaning system with a separate air compressor. However, the air compressor and pressurized air tank of 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 air-consuming systems, the air compressor's lifespan will be reduced due to the different air pressures required by these pneumatic devices. Furthermore, the poor stability of gas operation may lead to situations where electronic sensors are not effectively cleaned during cleaning system operation, posing a greater driving hazard to users.

[0006] On the other hand, the heat generated by the air compressor in the pneumatic damping system dissipates into the environment, while the hydraulic system may require an additional heating system to ensure that the liquid in the water tank does not freeze in cold environments, especially in winter. When commonly used electronic sensors are too dirty or their sensing parts are blocked by frost, they will malfunction, but the energy of the air compressor cannot be transferred to the water tank to provide warm water for cleaning or thawing the electronic sensors. As a result, the waste heat of the system cannot be fully and effectively utilized, thus causing energy waste. Utility Model Content

[0007] Therefore, this utility model provides an integrated system for passenger vehicles to address the aforementioned deficiencies in the prior art. More specifically, this disclosure provides a system for arranging 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 other components, and enabling the heat and other energy generated by one component (which would otherwise be lost to the environment) to be used to help the efficient operation of other components. It should be understood that the system and its operation method described herein are not limited to passenger vehicles but can be used in any system utilizing an air compressor, water tank, and optional electronic sensors.

[0008] Based on the disclosure herein, without limiting the scope of this disclosure in any way, in the embodiments disclosed herein, the passenger vehicle integrated system includes: an air compressor and a cleaning system.

[0009] The air compressor is connected to pressurized air tank one and pressurized air tank two respectively, and the air compressor, pressurized air tank one and / or pressurized air tank two are connected to a pneumatic vibration damping 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 one and / or pressurized air tank two, and hydraulically connected to the water tank. It is configured to spray gas or liquid from the nozzle into contact with an electronic sensor to clean dirt or defrost / de-ice its surface.

[0011] In some embodiments disclosed in this utility model, the passenger vehicle integrated system includes a controller that communicates electronically with at least an air compressor and a water pump, the controller controlling the activation of each component respectively.

[0012] In some embodiments disclosed in this utility model, the nozzle of the cleaning system is fluidly connected to the water tank, so that when the controller issues a command, 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 to defrost / de-ice them.

[0013] In some embodiments disclosed in this utility model, the nozzle of the cleaning system is pneumatically connected to the air compressor, so that the warm air generated by the air compressor can flow to the nozzle under the command of the controller. 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 in this utility model, the second pressurized gas tank stores gas at a lower pressure than the first pressurized gas tank. The fact that the second pressurized gas tank stores gas at a different pressure than the first pressurized gas tank allows two pneumatic systems operating at different pressures on a single passenger vehicle to share a single air compressor and use gas from two different pressurized gas tanks pneumatically connected to the same air compressor. For example, the first pressurized gas tank can serve the pneumatic shock absorption system of a passenger vehicle at a pressure of 18 bar, while the second pressurized gas tank can serve the pneumatic seat ventilation system of the same passenger vehicle at a pressure of 5 bar, while only a single air compressor is used to fill both the first and second pressurized gas tanks.

[0015] In some embodiments disclosed in this utility model, the second pressurized gas storage tank and the first pressurized gas storage tank are integrated into one tank body, and the interior of the tank body is divided into a first gas storage chamber and a second gas storage chamber. The gas storage tank integrates multiple gas storage chambers into one unit, which has high space utilization, low cost, and can provide an independent and stable gas source for multiple systems.

[0016] Some embodiments disclosed in this utility model also include:

[0017] Pressure regulating valve one, wherein the pressure regulating valve one is pneumatically connected to at least one of the pressurized gas storage tank one and the pressurized gas storage tank two;

[0018] Pressure regulating valve two is pneumatically connected to at least one of the pressurized gas storage tank one and the pressurized gas storage tank two.

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

[0020] Pressure regulating valve one and pressure regulating valve two are both pneumatically connected to a pressurized air tank. Pressure regulating valve one facilitates the flow of gas to a first pneumatic system at a set pressure, while pressure regulating valve two facilitates the flow of gas to a second pneumatic system at different set pressures, using only one pressurized air tank. For example, pressure regulating valve one can serve the pneumatic damping system of a passenger car by allowing only 18 bar of air from the pressurized air tank to flow into the system, while pressure regulating valve two can serve the pneumatic seat ventilation system of the same passenger car by allowing only 5 bar of air to flow into the system, both using a single pressurized air tank.

[0021] Some embodiments disclosed in this utility model also include:

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

[0023] Some embodiments disclosed in this utility model also include:

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

[0025] In some embodiments disclosed in this utility model, the air compressor and the water tank are in thermal communication, thereby promoting heat transfer between the air compressor and the water tank. The water tank is configured to at least partially contact the housing of the air compressor. The air compressor and the water tank are configured such that when the air pump of the air compressor operates, the heat generated causes the housing temperature to rise. The housing of the air compressor, through heat exchange, raises the temperature of the water tank body, which is at least partially in contact with the housing. Heat exchange occurs between the water tank body and the liquid inside, establishing thermal communication between the air compressor and the liquid.

[0026] In some embodiments disclosed in this utility model, the cleaning system further includes a heating device disposed between the nozzle and the electronic sensor, such that the gas or liquid ejected from the nozzle comes into contact with the heating device.

[0027] The heating device is electrically connected to the controller, which can issue commands to allow compressed air from the air compressor to be heated by the heating device and then ejected 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 in this utility model, the pressurized gas storage tank and the 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 casing 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 working, the heat generated will cause the pump casing temperature to rise. Through heat exchange, the pump casing of the water pump will raise the temperature of the tank body of the pressurized gas storage tank, which is at least partially in contact with the pump casing. Heat exchange occurs between the tank body and the gas inside it, establishing a thermal connection between the water pump and the pressurized gas storage tank.

[0029] In some embodiments disclosed in this utility model, the above-described passenger vehicle integrated system can also be applied to at least one other gas and / or water supply system besides the cleaning system.

[0030] This utility model has the following advantages:

[0031] (1) This utility model arranges the pneumatic, hydraulic and electronic sensor components of passenger cars in a more integrated manner. By sharing the air compressor and pressurized air tank of the pneumatic damping system with the cleaning system and other air and / or water supply systems, it reduces structural redundancy, improves integration, and reduces the weight of passenger cars. This can improve the operating efficiency of the entire passenger car integrated system and reduce system operating costs.

[0032] (2) On the one hand, this utility model 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 that hinders the normal operation of the electronic sensor in the environment, or to defrost / de-ice the electronic sensor, thereby eliminating or reducing the dependence of the water tank and air compressor on heating elements in cold climates, improving the cleaning efficiency of the electronic sensor while improving the utilization rate of the heat and waste heat generated by the operation of the air compressor.

[0033] (3) By equipping two pressurized gas storage tanks that store gases at different pressures, this utility model allows two pneumatic systems operating at different pressures on a single passenger vehicle to share one air compressor. Furthermore, a single pneumatic system can use gases from two pressurized gas storage tanks with different pressure values. Using multiple pressurized gas storage tanks can reduce the frequency of air compressor use when multiple systems are used simultaneously, avoid frequent flow regulation, improve the service life of the air compressor, and enhance the stability of the gas supply process. In addition, using multiple pressurized gas storage tanks with different pressure ranges to meet the gas demand of different gas 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. Alternatively, by equipping two pressure regulating valves that allow gases at different pressures to pass through, it is possible to use only one pressurized gas storage tank in different pneumatic systems, reducing the number of pressurized gas storage tanks used, thereby reducing the manufacturing cost and weight of the passenger vehicle.

Detailed Implementation

[0043] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0044] like Figure 1 As shown, this utility model provides an embodiment of a passenger vehicle integrated system 100, which includes an air compressor 110, an electronic sensor 150, and a cleaning system 140.

[0045] In this embodiment of the invention, the cleaning system 140 includes a water tank 130 and at least one nozzle 142a, 142b. The nozzles are pneumatically connected to the air compressor 110 or hydraulically connected to the water tank 130, and are configured such that gas or liquid ejected from the nozzles contacts the electronic sensor 150, facilitating cleaning and / or defrosting / de-icing of 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 this utility model, such as Figure 1 As shown, the passenger vehicle integrated system 100 also includes a pressurized air tank 112 and a pressurized air tank 114, both of which are pneumatically connected to the air compressor 110. Exemplarily, this pneumatic connection can be achieved through a sealed pipe connecting the two components within the passenger vehicle integrated system 100, or through any other method of transporting gas without loss to the environment.

[0047] In some embodiments disclosed in this utility model, the second pressurized gas storage tank 114 and the first pressurized gas storage tank 112 are integrated into one tank body, and the interior of the tank body is divided into a first gas storage chamber and a second gas storage chamber. The gas storage tank integrates multiple gas storage chambers into one unit, which has high space utilization, low cost, and can provide an independent and stable gas source for multiple systems.

[0048] In this embodiment of the invention, the air compressor 110 may be the air compressor 110 used to supply air to the air springs in the pneumatic damping system 120 installed in the vehicle. This allows other air-using units and the cleaning system 140 on the vehicle to share a single air intake source, meeting the requirements for vehicle lightweighting.

[0049] The pneumatic damping system 120 includes at least one air spring 121a; in this embodiment, it includes four air springs 121a, 121b, 121c, and 121d (one for each wheel in 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 gas pressurized by the air compressor 110 is stored in the pressurized gas storage tank 112 and is delivered to the corresponding air springs in a timely manner through the gas distribution valve 116 so that they can play a role such as shock absorption.

[0050] In some embodiments, the pressurized gas storage tank 114 may be pneumatically connected to nozzles 142a and 142b.

[0051] In some embodiments, the set pressure values ​​of the gas stored in the first pressurized gas storage tank 112 and the second pressurized gas storage tank 114 are not the same.

[0052] For example, the pressure of the gas stored in pressurized gas tank 112 is higher than the pressure of the gas stored in pressurized gas tank 114. Typically, the gas pressure used for cleaning the electronic sensor 150 is lower than the gas pressure in pressurized gas tank 112 used for the pneumatic damping system 120.

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

[0054] Using multiple pressurized air 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 regulation, improve the service life of the air compressor 110 and the stability of the air supply operation; in addition, it can eliminate or reduce the pressure regulation process, which can reduce the number of gas pressure regulating valves used and reduce costs; on the other hand, it can also shorten the gas supply response time.

[0055] In an embodiment of the utility model, a controller 160 electrically connected to the air compressor 110 is also included. The controller 160 sends a command to the air compressor 110 to deliver compressed gas to either the first pressurized air tank 112 or the second pressurized air tank 114.

[0056] In this embodiment of the utility model, at least one other air supply and / or water supply system 170 is also included. The air supply and / or water supply system 170 is pneumatically connected to the air compressor 110, pressurized air storage tank 112 and / or pressurized air storage tank 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 in a passenger vehicle that utilizes water or pressurized air to perform its function. Examples of such air and / or water supply systems 170 include, but are not limited to, another pneumatic damping system, another cleaning system, a seat massage system, or a seat ventilation system. Compressed air supplied from the air compressor 110 or liquid supplied from the water tank 130 can meet the functional requirements of at least one other air and / or water supply system 170.

[0058] In some embodiments of this utility model, the passenger vehicle integrated system further includes a gas distribution valve 116, which is connected to the air compressor 110, pressurized air tank one 112, and pressurized air tank two 114. The gas distribution valve 116 is connected to the pneumatic damping system 120, the cleaning system 140, or at least one other air supply and / or water supply system 170. In embodiments of this utility model, pressurized gas released from the air compressor 110, pressurized air tank one 112, and pressurized air tank two 114 can be distributed to the pneumatic damping 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] The gas distribution valve 116 can distribute gas from pressurized gas storage tanks at different storage pressures to different systems or equipment to meet multiple gas usage needs and simplify gas routing. The controller 160 is also electrically connected to the gas distribution valve 116. The controller 160 sends a signal to the gas distribution valve 116 to release the pressurized gas at an appropriate time.

[0060] In this embodiment of the invention, the water tank 130 is fluidly connected to the water pump 132, and the controller 160 is electrically connected to the water pump 132. This allows the controller 160 to send a signal to the water pump 132.

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

[0062] The controller 160 is electrically connected to the liquid distribution valve 134, which is connected to the cleaning system 140 or at least one other air and / or water supply system 170. The controller 160 signals the liquid distribution valve 134 to release liquid at an appropriate time. The released liquid is delivered to the cleaning system 140 or the other air and / or water supply system 170.

[0063] In some embodiments of this utility model, 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 exchange can be achieved in the following ways:

[0065] (i) Arrange the air compressors 110 in close proximity to the water tank 130 in space (e.g., within 5 mm of each other);

[0066] (ii) The air compressor 110 is fixed to the water tank 130 by bolting the air compressor 110 and the water tank 130 together so that there is no obvious space between them.

[0067] (iii) The air compressor 110 is fixed to the water tank 130 by welding the two parts together so that there is no obvious space between them;

[0068] (iv) By manufacturing integrated components, the air compressor 110 and the water tank 130 are formed as a single unit;

[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 kept around the water tank 130, reducing heat dissipation in the environment.

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

[0071] In this embodiment of the utility model, the tank body of the water tank 130 is configured to at least partially contact the housing of the air compressor 110. The air compressor 110 and the water tank 130 are configured such that when the air pump of the air compressor 110 is working, the heat generated will cause the temperature of the housing to rise. The housing of the air compressor 110 will raise the temperature of the tank body of the water tank 130, which is at least partially in contact with the housing, through heat exchange. Heat exchange will occur between the tank body and the liquid inside it, and a thermal connection will be established between the air compressor 110 and the liquid.

[0072] The heat exchange between the air compressor 110 and the water tank 130 allows any hot exhaust gas from the air compressor 110 to be transferred to the water tank 130, effectively heating the water in the water tank 130 without the need for additional heating elements. The heated water is then sent to nozzles 142a and 142b and sprayed onto the electronic sensor 150, thereby removing dirt or debris from the environment that may obstruct the normal operation of the electronic sensor 150, or defrosting / de-icing the electronic sensor 150. This heat exchange eliminates or reduces the water tank 130's dependence on heating elements, especially in cold climates where the water in the water tank 130 may freeze and clog the hydraulic system in the passenger vehicle; it also effectively utilizes the waste heat generated during the operation of the air compressor 110, avoiding direct release into the atmosphere and resulting energy waste. Furthermore, it should be noted that the liquid in the water tank 130 can be any liquid required to constitute different passenger vehicle systems, and the use of the term "water tank 130" does not imply a limitation on the liquids that can be used. For example, windshield washer fluid can be used as the liquid in water tank 130.

[0073] The compressed gas in the air compressor 110 also carries heat during operation, as the operation of the air compressor 110 raises the ambient temperature around and inside the air compressor 110. This heated compressed gas can be injected from nozzles 142a and 142b onto the electronic sensor 150, thereby removing dirt or debris from the environment that might hinder the normal operation of the electronic sensor 150, or defrosting / de-icing the electronic sensor 150. This effectively utilizes the heat generated during the operation of the air compressor 110 and eliminates or reduces the dependence on heating elements for the gas in the air compressor 110. Especially in cold climates, heating elements must be used, requiring more energy than in this embodiment to achieve the desired effect.

[0074] Now for special reference Figure 2 The diagram illustrates different embodiments of a passenger vehicle integrated system 100. The passenger vehicle integrated system 100 also includes a pressure regulating valve 118 and a pressure regulating valve 119, wherein the pressure regulating valve 118 is pneumatically connected to at least one of the pressurized air tanks 112 and 114; and the pressure regulating valve 119 is pneumatically connected to at least one of the pressurized air tanks 112 and 114.

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

[0076] In this embodiment of the invention, pressure regulating valve 118 allows gas to pass through at a higher pressure than pressure regulating valve 119. For example, pressure regulating valve 118 can serve the pneumatic damping system 120 of a passenger vehicle by allowing only 18 bar of air from pressurized air tank 112 into the system, while pressure regulating valve 119 can serve the pneumatic seat ventilation system of the same passenger vehicle by allowing only 5 bar of air into the system. This allows multiple pressures to be achieved using only a single pressurized air tank 112 in different pneumatically related systems, instead of adding the use of pressurized air tank 114 (e.g., ...). Figure 1 (As described in the embodiments). 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 storage tanks (such as...) can still be used. Figure 1 (in the embodiments) and Figure 2In the current embodiment, multiple pressure regulating valves are used in combination (not shown in the figure).

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

[0079] Now, special reference Figure 3 Different embodiments of a passenger vehicle integrated system 100 are shown. The passenger vehicle integrated system 100 also includes a heating device that can raise the temperature of the liquid injected onto the electronic sensor 150.

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

[0081] (i) The heating device is disposed between nozzles 142a, 142b and electronic sensor 150, such that gas or liquid ejected from the nozzles comes into contact with the heating device; or

[0082] (ii) The heating device is thermally connected to the electronic sensor 150; or

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

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

[0085] The resistance wires can be powered directly by the vehicle's battery or engine power, or they can be controlled by the controller 160, which sends a heating signal to the resistance wires 190a and 190b when the electronic sensor 150 becomes dirty or frosted / iced. This provides replacement or supplementary heat when gaseous or liquid cleaning agents reach 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, resistance wires 190a and 190b can be positioned very close to the electronic sensor 150 (not shown) to provide heat directly to the surface of the electronic sensor 150.

[0088] Similarly, the resistance wires 190a and 190b, which serve as heating devices, can also be chip resistors, for example, formed with a geometry having 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 needed.

[0089] It should be noted that the advantages of having at least resistance wires 190a and 190b are not contingent on the air compressor 110 being thermally connected to the water tank 130.

[0090] refer to Figures 4a-4c The figure illustrates a passenger vehicle 200 and provides an example of a passenger vehicle integrated system 100 within the vehicle to demonstrate how the 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 passengers can use the instrument display 210 to perform various functions (e.g., turning the radio on and off, adjusting the temperature setting, checking the fuel level, etc.). The passenger vehicle 200 has at least one headlight 220 that is turned on in this embodiment.

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

[0092] The pressurized air tank 112, which stores the heat generated during the operation of the air compressor 110, and the water pump 132 are also thermally connected. This allows the heat generated during the operation of the water pump 132 to maintain the gas in the pressurized air tank 112 at a temperature higher than ambient, or to further heat the gas in the pressurized air tank 112. The thermal connection between the pressurized air tank 112 and the water pump 132 can be achieved through... Figure 1 The same or similar manner is used between the air compressor 110 and the water tank 130 described herein.

[0093] In this embodiment, the gas distribution valve 116 and the liquid distribution valve 134 are also thermally connected to help reduce heat loss when the gas and liquid in the passenger vehicle integrated system 100 are transported from one location to the next.

[0094] By keeping heated gas and liquid in very close proximity, the ambient temperature near the gas and liquid increases, slowing down the rate of heat transfer with the environment. The same applies to the pipelines through which gas and liquid pass in the passenger vehicle integrated system 100.

[0095] For example, if warm water is flowing from tank 130 through the vehicle integrated system 100 to nozzle 142a, while warm air is flowing from pressurized storage tank 112 through the vehicle integrated system 100 to nozzle 142a (or any other part of the vehicle integrated system 100), by bringing the exteriors of the two pipelines through which the warm water and warm air flow into contact with each other, at least a portion of the surface area in each pipeline will be at a higher temperature than the ambient temperature. This promotes heat retention in each pipeline by minimizing the surface area in each pipeline from which heat is transferred to the ambient air via convection. In other words, as many pipelines conveying hot gases and hot liquids as possible are arranged in contact.

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

[0097] The passenger vehicle 200 also includes an electronic sensor 150, which in this embodiment assists in performing adaptive cruise control. The electronic sensor 150 sends signals to the environment, and if any signals are returned, it transmits this information to a controller 160. If adaptive cruise control malfunctions, the controller 160 instructs the vehicle to decelerate. The air compressor 110, water pump 132, gas distribution valve 116, liquid distribution valve 134, instrument display 210, headlights 220, and electronic sensor 150 all communicate electronically with the controller 160. The passenger vehicle integrated system 100 also includes at least one nozzle 142a, which in this embodiment is configured such that the gas and liquid ejected from the nozzle 142a contact the parts of the electronic sensor 150 that transmit and receive signals.

[0098] Figure 4a A passenger vehicle 200 in normal operation was shown, including a normally functioning electronic sensor 150.

[0099] Figure 4b A passenger vehicle 200 was demonstrated where the electronic sensor 150 malfunctioned due to the accumulation of dirt 230 on the parts of the sensor that transmit and receive signals. This dirt 230 could be dirt from the road, mud, rainwater, snow, ice, or frost buildup on the outside of the sensor, lubricating oil spilled from other parts of the passenger vehicle 200, or any other foreign matter or substance adhering to the electronic sensor 150. This dirt 230 can 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 vehicles or objects while using adaptive cruise control.

[0100] Figure 4c This illustrates how gas from a pressurized gas tank or liquid from a water tank 130 is sprayed from nozzle 142a and contacts the surface of electronic sensor 150 to remove dirt 230. Once this function is achieved, the passenger vehicle 200 will return to normal. Figure 4a The state of the embodiment.

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

[0102] Furthermore, the controller 160 can be installed on each component of the passenger vehicle integrated system 100, enabling the controller network to operate in series to drive components to run at a given time, monitor the temperature of each component, monitor the normal operation or fault status of each component, and achieve precise control of the controlled object or any other required 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 to automatically take countermeasures when the system malfunctions (for example, receiving fault information from the adaptive cruise control system and automatically activating the cleaning system 140 to remove dirt 230 from the electronic sensors 150 of the adaptive cruise control system).

[0103] Although the present invention has been described in detail above with general descriptions and specific embodiments, some modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, all such modifications or improvements made without departing from the spirit of the present invention fall within the scope of protection claimed by the present invention.
