Detailed Description
To facilitate an understanding of the present application, the present application will now be described more fully with reference to the accompanying drawings. Preferred embodiments of the present application are illustrated in the accompanying drawings. This application may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete.
Referring to fig. 1, a method for controlling air supply of a vehicle includes steps S100, S200, and S300.
Step S100, seat state parameter information corresponding to each seat in the vehicle is obtained.
Specifically, the air supply means supplying cold air or hot air to the interior space of the vehicle to cool or heat the interior space of the vehicle. The vehicle generally refers to all vehicles, and any vehicle that has a seat in an internal space and requires cooling or heating of the internal space may be supplied with air by the vehicle air supply control method provided by the present application. For example, in a more detailed embodiment, the vehicle may be a large or medium sized bus, train, or the like. The seat state parameter information is parameter information used for representing whether each seat has a passenger in the state, and the specific type of the seat state parameter information is not unique, and the seat state parameter information can be selected in different ways according to actual use scenes.
It can be understood that the seat state parameter information is not obtained in a unique manner, and in one embodiment, a parameter collecting device may be arranged in the vehicle, the seat state parameter information corresponding to each seat is collected in real time by the parameter collecting device and sent to the controller, and the controller receives the seat state parameter information corresponding to each seat, that is, obtains the seat state parameter information corresponding to each seat in the vehicle. In other embodiments, the seat state parameter information may also be obtained by other means such as user input.
And step S200, obtaining the seat information with passengers according to the state parameter information of each seat.
Specifically, the seat state parameter information may be used to indicate whether a passenger is present in the seat, and therefore, after obtaining the seat state parameter information corresponding to each seat, the controller may obtain whether the passenger is present in the current seat by combining the seat state parameter information. After analyzing all the seat state parameter information, the controller can obtain all the seats, which seats have passengers and which seats do not have passengers.
And step S300, controlling an air supply assembly of the vehicle to supply air to the seat corresponding to each piece of seat information.
Specifically, after obtaining the seat information corresponding to all the seats with passengers in each seat, the controller further controls the air supply assembly arranged in the vehicle to be opened, and simultaneously supplies air to all the seats with passengers, so as to realize the cooling or heating operation of the area corresponding to each seat. It will be appreciated that at this time, for seats where no passenger is seated, there will be no delivery of cold or hot air. Through the scheme of this embodiment, can carry out corresponding air supply according to actual passenger position, avoid supplying air simultaneously and produce surplus refrigeration (heat) volume, cause huge waste to the energy, also avoid unnecessary refrigeration (heat) volume simultaneously, cause uncomfortable sense for the human body in the vehicle inner space, this kind of discomfort probably leads to human pathological change. Furthermore, the method can avoid the ineffective work consumption which is done for a long time in the past, has adverse effect on the service life of the air supply assembly, also avoids the manufacture of excessive unnecessary refrigerating (heating) quantity, and aggravates the pollution to the environment.
Referring to fig. 2, in one embodiment, the seat state parameter information includes pressure parameter information and infrared parameter information, and the step S200 includes a step S210, a step S220, and a step S230.
Step S210, comparing and analyzing the pressure parameter information and the preset pressure threshold range respectively, and simultaneously comparing and analyzing the infrared parameter information and the preset infrared threshold range respectively. And step S220, when the pressure parameter information and the infrared parameter information corresponding to the same seat are respectively in the preset pressure threshold range and the preset infrared threshold range, obtaining that the passenger is seated in the seat. And step S230, when the pressure parameter information corresponding to the same seat is not in the preset pressure threshold range and/or the corresponding infrared parameter information is not in the preset infrared threshold range, obtaining that the seat does not have passengers.
Specifically, in the scheme of this embodiment, the seat state parameter information that each seat corresponds is gathered through parameter acquisition device and is sent, and this parameter acquisition device is including being used for detecting pressure detector and the infrared detector that the seat bore pressure simultaneously, and in the actual operation in-process, pressure detector real-time detection seat bore pressure parameter information, the infrared parameter information of infrared detector real-time detection seat top, both send pressure parameter information and infrared parameter information to the controller in real time and carry out the analysis.
The controller is pre-stored with a preset pressure threshold range for representing the size of human body pressure borne by the seat and a corresponding preset infrared threshold range for representing the presence of a passenger on the seat, the controller respectively compares and analyzes each piece of pressure parameter information with the preset pressure threshold range and simultaneously compares and analyzes each piece of infrared parameter information with the preset infrared threshold range, only if the pressure parameter information on the same seat is in the preset pressure threshold range and the infrared parameter information is also in the preset infrared threshold range, the seat is considered to be occupied by the passenger, and otherwise, the seat is considered to be unoccupied by the passenger.
In the scheme of this embodiment, only when detecting that pressure parameter information and infrared parameter information all represent that this seat has the passenger to take simultaneously, think that this seat has the passenger to take, avoid appearing that the passenger places the heavy object on the seat, or under the special circumstances such as the passenger is detected when passing through the seat, the controller thinks that this seat takes the condition of passenger and takes place, can effectively guarantee the accuracy of testing result.
It should be noted that the specific types of pressure detectors and infrared detectors are not exclusive and in one embodiment, may be implemented using pressure sensors and infrared sensors, as described in conjunction with fig. 3 and 4. Fig. 3 shows a pressure sensor in which, when external pressure (passenger gravity) acts on a sensing pad, the sensing pad is deformed, causing deformation of a soft iron block, so that an electromagnetic induction phenomenon occurs by interaction of a permanent magnet and the soft iron block; and the pressure is obtained through the generated current or voltage, so that pressure parameter information is obtained and transmitted to the controller. The infrared sensor shown in fig. 4 can sense and detect the infrared pop of a human body, obtain infrared parameter information, send the infrared parameter information to the controller, and compare and analyze the infrared parameter information with a general human body infrared pop range (i.e., a preset infrared threshold range) set in the controller, thereby determining whether a passenger is present.
Referring to fig. 5, in one embodiment, step S300 includes step S310.
In step S310, the air blowing unit of the vehicle is controlled to blow air to the seats corresponding to the seat information at a uniform air blowing amount.
Specifically, in the solution of the present embodiment, when air is supplied to each seat, the cold air or hot air generated by the air supply assembly is equally distributed to each seat by using an equal distribution principle, so as to realize cooling or heating of all seats with passengers. Through the formula, the conditions that the air quantity of certain seats is too much and the air quantity of some seats is too little can be avoided, and bad experience is caused to users.
Referring to fig. 6, in one embodiment, step S300 includes step S320 and step S330.
And step S320, controlling the opening of the air supply outlet of the seat corresponding to each piece of seat information. And step S330, controlling a frequency converter and an air volume valve of the vehicle to generate cold air or hot air, and simultaneously controlling an electronic throttle valve arranged at a seat corresponding to each seat information to open to convey the cold air or the hot air to the corresponding seat.
Specifically, referring to fig. 7, in the solution of this embodiment, the air supply assembly includes an air volume valve, a frequency converter and an electronic throttle valve, the controller generates a suitable amount of cold (heat) through adjustment of the frequency converter and the air volume valve, the generated cold air or hot air is delivered to the air supply opening corresponding to each seat through the air supply duct, the electronic throttle valve is disposed on the air supply duct corresponding to each seat, and the generated cold air or hot air can be delivered to the seat with the air supply requirement, that is, the seat corresponding to the seat information where the passenger is seated, by controlling the opening of the air supply opening corresponding to the seat with the air supply requirement and adjusting the opening of each electronic throttle valve.
Referring to fig. 8, in an embodiment, after step S300, the method further includes step S400.
And step S400, when receiving a manual adjustment instruction sent by a passenger, adjusting the air supply of the seat corresponding to the passenger according to the manual adjustment instruction.
Specifically, referring to fig. 7, when the controller controls the air supply assembly to supply air to the seat corresponding to each seat information, the air may be supplied to all the seats simultaneously in other forms such as equal air supply, and the amount of air supplied to each seat is constant. In the actual use process, the requirements of cold air or hot air for different passengers are different. In order to ensure that the air output of each seat is matched with the passenger of the seat and improve the user experience, in the scheme of the embodiment, each seat is also correspondingly provided with a semi-automatic switch, each semi-automatic switch is connected to the controller, and the passenger sends a manual adjusting instruction to the controller through the semi-automatic switch. After receiving the manual adjustment instruction, the controller adjusts the air supply of the corresponding seat through the manual adjustment instruction so as to meet the air supply requirement of the passenger of the seat.
It will be appreciated that the particular type of manual adjustment command is not exclusive and in a more detailed embodiment the manual adjustment command includes any of turning off the supply air, turning down the supply air volume and increasing the supply air volume. That is, the passenger can control the air supply closing, the air supply increasing and the air supply decreasing of the seat through manual adjustment.
Further, in one embodiment, the vehicle air supply control method further includes: and when the failure of the feedback of the seat state parameter information is detected, controlling an air supply component of the vehicle to supply air according to a control instruction input by a user.
Specifically, referring to fig. 9, the air supply control method according to each embodiment is implemented by the controller under the condition that the seat state parameter information corresponding to each seat is acquired. However, in the actual operation process, the parameter collecting device for collecting the seat state parameter information may malfunction, and when the parameter collecting device includes a pressure detector for collecting the pressure parameter information, an infrared detector for collecting the infrared parameter information, and an information processor for processing the pressure parameter information and the infrared parameter information and feeding them back to the controller, the specific malfunction type may be malfunction of the pressure detector or the infrared detector, and may also be malfunction of the information processor. No matter which device fails, the complete seat state parameter information cannot be fed back to the controller, and at this time, the user (specifically, the driver or the passenger) is required to manually start the air supply assembly to supply air.
In the scheme of the embodiment, the vehicle is correspondingly provided with a hand-operated button, the hand-operated button is connected with the controller, the issuing of the control instruction is realized through the hand-operated button, and the air supply assembly is started to operate under the manual control of a user to supply air to the inner space of the vehicle. It can be understood that, because in this state, the seat state parameter information cannot be obtained, and it cannot be known which seat has a passenger and which seat does not have a passenger, the air supply assembly will supply air to all seats simultaneously under the control of the hand-operated button.
It is to be understood that the implementation manner of detecting the failure of the feedback of the seat state parameter information is not unique, and in one embodiment, it may be determined whether the seat state parameter information is received within a preset time. Specifically, by setting a preset time in the controller, timing will be started after the controller receives the seat state parameter information, and if the timing reaches the preset time, the controller still does not receive the seat state parameter information again, that is, the feedback of the representation seat state parameter information fails.
Further, in one embodiment, when failure of seat state parameter information feedback is detected, the method further includes: and outputting information missing prompt information or system failure prompt information.
Specifically, the controller can also output different prompt messages to the user according to different types of failure feedback of the seat state parameter information, and when the controller only receives pressure parameter information or infrared parameter information in the seat state parameter information, the controller outputs information missing prompt messages to inform the user; and when the controller does not receive the pressure parameter information and the infrared parameter information at the same time, system failure prompt information is output to inform a user. The air supply is started conveniently by operating the button by hand when a user needs the air supply device. It can be understood that the output mode of the information missing prompt message or the system failure prompt message is not unique, and can be realized by adopting alarm devices such as sound, light and the like, and different types of prompt messages can be output in different modes as long as the prompt messages are convenient for users to know.
According to the vehicle air supply control method, the seat state parameter information corresponding to each seat in the vehicle can be acquired, the seat information taken by the passenger can be analyzed, and finally the air supply assembly of the vehicle can simultaneously supply air to the seat corresponding to each seat information. Through above-mentioned scheme, the vehicle is inside when sending wind, can carry out the air supply as required to passenger's quantity and passenger's position, can not cause unnecessary energy waste, and the mode of this kind of air supply can avoid the invalid air supply of air supply subassembly to produce too much loss simultaneously to strengthen its life, have stronger operational reliability.

And when the pressure parameter information and the infrared parameter information corresponding to the same seat are respectively in the preset pressure threshold range and the preset infrared threshold range, the passenger in the seat is obtained. And when the pressure parameter information corresponding to the same seat is not in the preset pressure threshold range and/or the corresponding infrared parameter information is not in the preset infrared threshold range, the condition that the seat has no passenger is obtained.

The seat state parameter information may be used to indicate whether a passenger is present in the seat, and therefore, after obtaining the seat state parameter information corresponding to each seat, the controller 20 may obtain whether the passenger is present in the current seat by combining the seat state parameter information. The controller 20 can obtain which seats have passengers and which seats do not have passengers in all the seats after analyzing all the seat state parameter information.
After obtaining the seat information corresponding to all the seats with passengers in each seat, the controller 20 further controls the air supply assembly 30 provided in the vehicle to be turned on, and simultaneously supplies air to all the seats with passengers, thereby performing cooling or heating operation for each region corresponding to the seat.

It will be appreciated that since in this state, the seat state parameter information is not available, and it is not known which seat has a passenger and which seat does not have a passenger, the air supply assembly 30 will supply air to all seats simultaneously under the control of the hand button 50.
In a more detailed embodiment, the vehicle air supply control system may further include a semi-automatic switch 40 and a hand button 50, so as to implement the functions that can be implemented by the semi-automatic switch 40 and the hand button 50, which will not be described herein again.
