[0039] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features in the embodiments may be combined with each other.

[0040] The present invention will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0041] In some embodiments of the present application, the vehicle includes a solar cell, a storage battery, and a control module. The control module is used to obtain a first reserve power of the solar cell, and when it is determined that the first reserve power of the solar cell is not less than a preset first preset power, control the solar cell to supply power to the ventilation and temperature control system; when the first reserve power of the solar cell is less than the first preset power, obtain a second reserve power of the storage battery, and when it is determined that the second reserve power of the storage battery is not less than the preset second preset power, control the storage battery to supply power to the ventilation and temperature control system.

[0042] Specifically, the ventilation and temperature control system is powered by solar cells or batteries, and the priority of solar cells is higher than that of batteries. The control module detects the power of solar cells and batteries, and controls one of the solar cells and batteries to power the ventilation and temperature control system according to the power of the solar cells and batteries. That is, both the solar cells and batteries in the vehicle can be used as energy supply devices to provide electrical energy for the ventilation and temperature control system to meet the operating requirements of each module in the ventilation and temperature control system.

[0043] It is understandable that the control module can detect the power levels of the solar cell and the battery to reasonably select one of the two to power the ventilation and temperature control system.

[0044] The control method for the ventilation and temperature control system of a vehicle according to the embodiment of the present application includes the following steps: when the ventilation and temperature control system is turned on, the control module obtains the first reserve power of the solar cell, and the first reserve power is the current power of the solar cell. When it is determined that the first reserve power of the solar cell is not less than the first preset power, the control module controls the solar cell to supply power to the ventilation and temperature control system; when it is determined that the first reserve power of the solar cell is less than the first preset power, the control module obtains the second reserve power of the battery, and the second reserve power is the current power of the battery. When it is determined that the second reserve power of the battery is not less than the second preset power, the control module controls the battery to supply power to the ventilation and temperature control system.

[0045] When the ventilation and temperature control system is turned on, the power of the solar cell is first detected. When the power of the solar cell meets the working requirements of the ventilation and temperature control system, the solar cell supplies power to the ventilation and temperature control system. When the power of the solar cell cannot meet the working requirements of the ventilation and temperature control system, the power of the battery is detected. When the power of the battery meets the working requirements of the ventilation and temperature control system, the battery supplies power to the ventilation and temperature control system.

[0046] It can be understood that when the first reserve power is not lower than the first preset power, it means that the current power of the solar cell meets the working requirements of the ventilation and temperature control system, and the ventilation and temperature control system can be powered by the solar cell; when the first reserve power is lower than the first preset power, it means that the current power of the solar cell cannot meet the working requirements of the ventilation and temperature control system; when the second reserve power is not lower than the second preset power, it means that the current power of the battery meets the working requirements of the ventilation and temperature control system, and the ventilation and temperature control system can be powered by the battery.

[0047] When the ventilation and temperature control system is turned on, the power supply priority of the solar cell is higher than that of the battery. The power of the solar cell is detected first. When the power of the solar cell is sufficient, the ventilation and temperature control system is powered by the solar cell first. At the same time, when the power of the solar cell is insufficient, the battery powers the ventilation and temperature control system. Therefore, the ventilation and temperature control system can be powered by the solar cell and the battery respectively, thereby extending the battery life of the ventilation and temperature control system.

[0048] When the solar cell is supplying power to the ventilation and temperature control system, the power of the solar cell is detected in real time to determine whether the solar cell meets the use requirements of the ventilation and temperature control system. When the power is insufficient, it can be switched to the battery-powered working state in time, thereby improving the reliability of the ventilation and temperature control system.

[0049] It should be noted that solar cells can convert light energy into electrical energy and store it. When the solar cells are fully charged, the solar cells can add extra electricity to the battery until the battery is fully charged. In this way, light energy can be fully utilized, which is environmentally friendly and can save the energy consumption cost of the vehicle.

[0050] According to the control method of the ventilation and temperature control system of the embodiment of the present application, the ventilation and temperature control system is powered by solar cells and batteries. By detecting the power levels of the solar cells and batteries, the power supply device of the ventilation and temperature control system is reasonably selected to improve the working reliability of the ventilation and temperature control system and extend the endurance of the ventilation and temperature control system. This is environmentally friendly and can save the energy consumption cost of the vehicle.

[0051] like Figure 2 As shown, the solar cell, the storage battery and the control module can communicate with each other in pairs, thereby realizing the above control method.

[0052] In some embodiments of the present application, the ventilation and temperature control system further comprises: a solar panel for supplying electric energy to the battery. Figure 3 , the solar panel can convert solar energy into electrical energy through a converter and store it in a battery. The battery is provided with a power sensor, which can be used to detect the power of the battery. When the battery power is less than 60%, a signal can be fed back to the solar panel, and the solar energy can be converted into electrical energy through a converter and stored in the battery to replenish the battery power. Among them, the electrical energy converted by the solar panel is supplied to the battery, so that the solar panel is arranged on the sunroof, window glass or front windshield of the vehicle, which can solve the problem of being unable to start due to battery depletion due to long-term parking.

[0053] In some embodiments of the present application, the ventilation and temperature control system includes the following working modes: in-vehicle cooling mode, in-vehicle heating mode, in-vehicle ventilation mode, and out-vehicle ventilation mode, and the multiple modes can be switched between each other. Among them, the ventilation and temperature control system includes at least two of the above working modes to meet the user's needs for vehicle ventilation or temperature control.

[0054] It should be noted that the "in-vehicle cooling mode, in-vehicle heating mode, and in-vehicle ventilation mode" here refer to the working modes of the ventilation and temperature control system when the user is inside the vehicle, and the "out-vehicle cooling mode, out-vehicle heating mode, and out-vehicle ventilation mode" refer to the working modes of the ventilation and temperature control system when the user holding the mobile terminal is outside the vehicle. The user can select the working mode of the ventilation and temperature control system through the mobile terminal outside the vehicle. Therefore, whether the user is inside or outside the vehicle, there are corresponding temperature control and ventilation modes, which can better meet the user's usage needs.

[0055] The mobile terminal may be a mobile phone, a tablet computer or other device, and the mobile terminal may communicate with the control module through software such as APP. Figure 3 , can communicate with the main controller in the vehicle through the mobile phone APP to realize the functions of the battery for multiple components in the vehicle, thereby controlling the ventilation and temperature control system to switch to one of the above-mentioned outdoor cooling mode, outdoor heating mode, and outdoor ventilation mode.

[0056] The mobile terminal may also be a vehicle key. When the driver turns on the key unlocking button, the main controller may also receive the control signal and transmit the control command to the battery.

[0057] In some embodiments of the present application, the control method further includes: when the ventilation and temperature control system enables the vehicle external cooling mode, the control module controls the air conditioner and the air quality sensor to be turned on, and the working mode of the air conditioner is the external circulation mode. At the same time, the air quality parameter outside the vehicle detected by the air sensor is obtained, and the air quality parameter is compared with the first preset air quality parameter range. When it is determined that the air quality parameter outside the vehicle is not within the first preset air quality parameter range, the air conditioner is controlled to switch to the internal circulation mode.

[0058] The outdoor cooling mode is when the user is outside the vehicle and uses the mobile terminal to send instructions to the control module. The control module controls the ventilation and temperature control system to enable the outdoor cooling mode to cool the vehicle.

[0059] In an environment with high ambient temperature, when the user needs to enter or drive the vehicle, in order to prevent the temperature inside the vehicle from being too high, the ventilation and temperature control system can be controlled to enable the outdoor cooling mode to lower the temperature inside the vehicle. When the user enters the vehicle, the environment inside the vehicle is suitable for the user to ride or drive, thereby improving the user experience.

[0060] When the air conditioner is in the external circulation working mode, the air quality sensor can detect the air quality parameters outside the vehicle in real time. When the air quality parameters are within the first preset air quality parameter range, it means that the air quality outside the vehicle meets the standard for entering the vehicle, that is, the air quality outside the vehicle meets the standard.

[0061] It is understandable that the air quality parameter may include at least one of the following parameters: sulfur dioxide concentration, nitrogen dioxide concentration, inhalable particulate matter concentration, etc. When the air quality parameter is within the first preset air quality parameter range, it means that the air quality outside the vehicle is good and ventilation can be performed; when the air quality parameter is not within the first preset air quality parameter range, it means that the air quality outside the vehicle is poor and the external circulation mode of the air conditioner needs to be turned off and the internal circulation mode needs to be turned on to cool the interior of the vehicle.

[0062] In a further embodiment of the present application, after turning on the air conditioner and the air quality sensor, the control method further includes: turning on the infrared sensor, and the control module obtains the parameters of the people inside the vehicle detected by the infrared sensor.

[0063] When it is determined that there is a reserved person inside the vehicle based on the acquired vehicle internal personnel parameters, the carbon dioxide concentration inside the vehicle is detected and compared with a first preset concentration value; when the carbon dioxide concentration is not lower than the first preset concentration value, the air conditioner is controlled to turn on the external circulation mode.

[0064] Specifically, the infrared sensor can detect the parameters of personnel inside the vehicle. When there are reserved personnel inside the vehicle and the air conditioner is not in the external circulation mode, it is necessary to detect the carbon dioxide concentration inside the vehicle, and when the carbon dioxide concentration is not lower than the first preset concentration, control the air conditioner to turn on the external circulation mode to prevent carbon dioxide poisoning of the reserved personnel due to excessively high carbon dioxide concentration inside the vehicle, thereby improving the working reliability of the ventilation and temperature control system.

[0065] It is understandable that when the air conditioner is in the internal circulation mode and there are reserved persons in the vehicle, the carbon dioxide concentration in the vehicle will gradually increase, and too high a carbon dioxide concentration will affect the health of the reserved persons. It is necessary to monitor the carbon dioxide concentration in the vehicle in real time to prevent the carbon dioxide concentration in the vehicle from being too high. The concentration of carbon dioxide can be detected by a carbon dioxide sensor. The activation condition of the carbon dioxide sensor can be that the air conditioner is activated for internal circulation or it is determined that there are reserved persons in the vehicle.

[0066] In some embodiments of the present application, after turning on the air conditioner and the air quality sensor, the control method also includes: controlling the temperature sensor to turn on, the control module obtains the real-time temperature inside the vehicle detected by the temperature sensor, and controls the air volume level of the air conditioner according to the real-time temperature.

[0067] The temperature sensor can detect the temperature inside the vehicle in real time, and the controller can adjust the air volume level of the air conditioner according to the detected temperature parameter. The temperature parameter obtained by the temperature sensor can be compared with a first preset temperature value, and the working mode of the air conditioner can be adjusted when the temperature inside the vehicle reaches the first preset temperature value, such as when the air conditioner reduces the temperature inside the vehicle to the first preset temperature value, the controller can reduce the air volume level of the air conditioner.

[0068] Further, when the control module adjusts the air volume level of the air conditioner, the timing module in the ventilation and temperature control system starts timing, and when the timing module reaches the preset time value, the control module controls the air conditioner to turn off. Optionally, the preset time value can be 5 minutes or 10 minutes, which is not specifically limited.

[0069] It can be understood that the temperature sensor is used to detect the temperature inside the car when the outdoor cooling mode is working. The controller can adjust the working mode of the air conditioner (such as the air volume gear) according to the temperature inside the car, and count the time through the timing module. When the timing time reaches the preset time value, it means that the temperature inside the car has been adjusted, and the air conditioner is controlled to be turned off.

[0070] When the internal temperature of the vehicle reaches the first preset temperature value, it indicates that the target temperature adjustment is achieved. At this time, the temperature inside the vehicle can be maintained by adjusting the working mode of the air conditioner by the control module to prevent excessive deviation of the temperature adjustment. The first preset temperature value and the preset time value can be set during the design, and can also be set and selected by the user in the mobile terminal, so as to better improve the user experience.

[0071] It should be noted that the temperature sensor detects the real-time temperature inside the vehicle when the air conditioner is in the internal circulation working mode or the external circulation working mode. Its function is to assist in adjusting the air volume gear of the air conditioner to prevent excessive temperature adjustment deviation and improve the working reliability of the ventilation and temperature control system.

[0072] In some embodiments of the present application, the step of the timing module starting timing also includes: when the timing time of the timing module does not reach a preset time value, when the door lock sensor detects a door lock opening signal, the timing module stops timing.

[0073] It is understandable that when the door lock sensor detects a door lock opening signal, it means that the user may enter the vehicle. At this time, the user can further adjust the working mode of the ventilation and temperature control system through the dashboard and other devices in the vehicle according to needs. At this time, there is no need for the timing module to continue timing.

[0074] In some embodiments of the present application, the control method also includes: when the ventilation and temperature control system enables the outdoor ventilation mode, the air conditioner is controlled to be turned on, and the working mode of the air conditioner is the external circulation mode, and the timing is started at the same time when the air conditioner is turned on. When the accumulated time of the timing reaches the first preset time value, the air conditioner is controlled to be turned off.

[0075] Among them, the outside ventilation mode means that the user is outside the vehicle and sends instructions to the control module by operating the mobile terminal. The control module controls the ventilation and temperature control system to enable the outside ventilation mode to ventilate the inside of the vehicle. When the air conditioner is turned on the external circulation working mode, the air outside the vehicle can be introduced into the vehicle for ventilation, improving the air quality inside the vehicle.

[0076] It should be noted that the timing module can be used to count the time while the air conditioner is turned on. When the accumulated time reaches a first preset time value, the air conditioner is controlled to be turned off. The first preset time value can be set according to the user's usage requirements to meet the different usage requirements of the user. By limiting the working time of the outdoor ventilation mode through the timing module, the problem of obvious changes in the temperature inside the vehicle due to excessive ventilation time can be prevented.

[0077] It is understandable that when the temperature difference between the outside and inside of the vehicle is large and the vehicle is in the outside ventilation mode for a long time, the temperature inside the vehicle will be affected. For example, when the outside temperature is lower than the inside temperature, the long-term ventilation action will cause the inside temperature to drop.

[0078] In some embodiments of the present application, the control method also includes: when the ventilation and temperature control system enables the outdoor heating mode, controlling the far-infrared heating device and the temperature sensor to turn on, the control module obtains the real-time temperature inside the vehicle detected by the temperature sensor, and controls the heating power of the far-infrared heating device according to the real-time temperature.

[0079] The outdoor heating mode refers to the user being outside the vehicle and sending instructions to the control module by operating the mobile terminal. The control module controls the ventilation and temperature control system to enable the outdoor heating mode to adjust the temperature inside the vehicle. When the far-infrared heating device is turned on, the temperature inside the vehicle can be increased.

[0080] Specifically, when the outdoor heating mode is enabled, the far-infrared heating device can communicate with the temperature sensor. When the far-infrared heating device is turned on, it can send a signal to the temperature sensor. The temperature sensor turns on and detects the internal temperature of the vehicle in real time. The control module can control the heating power of the far-infrared heating device according to the real-time temperature inside the vehicle.

[0081] Among them, when the outdoor heating mode is enabled, the far-infrared heating device can be started at the maximum heating power to quickly increase the temperature inside the vehicle. At the same time, the temperature sensor detects the temperature inside the vehicle in real time. When the temperature reaches the second preset temperature value, it can feedback the signal to the control module and the timing module. The control module can adjust the power of the far-infrared heating device in real time according to the signal of the temperature sensor to ensure the stability of the temperature inside the vehicle. The timing module can synchronize the timing. When the preset time is reached, the timing module can send a signal to the control module, and the control module controls to turn off the far-infrared heating device.

[0082] Furthermore, when the timing time of the timing module does not reach the preset time value, the timing module stops timing when the door lock sensor detects the door lock opening signal. At the same time, the timing module can feedback the signal to the carbon dioxide sensor, and the carbon dioxide sensor can detect the carbon dioxide concentration inside the vehicle in real time. When the concentration of carbon dioxide reaches the preset concentration value (such as 0.1%), the feedback signal is sent to the control module, and the control module controls the air conditioner to turn on the external circulation working mode, and turns off the air conditioner after the air conditioner has been in the external circulation mode for a period of time, so as to prevent the carbon dioxide concentration inside the vehicle from being too high and improve the working reliability of the ventilation and temperature control system.

[0083] When the timing module stops timing due to receiving the door lock opening signal, the timing module can feedback the signal to the dew point sensor, and the dew point sensor can detect the dew point of the front windshield and the left and right front door glasses in real time. When the dew point is detected, the feedback signal is sent to the control module, and the control module controls the air conditioner to turn on the defrost mode to prevent the front windshield and the left and right front door glasses from fogging. When the air conditioner turns on the defrost mode, the signal can be fed back to the timing module, the timing module starts timing, and after a period of timing, the feedback signal is sent to the control module, and the control module controls the air conditioner to turn off.

[0084] In some embodiments of the present application, the control method further includes: when the ventilation and temperature control system enables the in-vehicle cooling mode, controlling to turn on the air conditioner and the air quality sensor, and the working mode of the air conditioner is the external circulation mode. The control module obtains the air quality parameter outside the vehicle detected by the air quality sensor, and compares the air quality parameter with the second preset air quality parameter range. When it is determined that the air quality parameter outside the vehicle is not within the second preset control quality parameter range, the air conditioner is controlled to switch to the internal circulation mode.

[0085] When the air conditioner is in the external circulation working mode, the air quality sensor can detect the air quality parameters outside the vehicle in real time. When the air quality parameters are within the second preset air quality parameter range, it means that the air quality outside the vehicle meets the standard for entering the vehicle, that is, the air quality outside the vehicle meets the standard.

[0086] In-vehicle cooling mode is when the user is inside the vehicle and sends instructions to the control module by operating the operation panel in the vehicle that can communicate with the control module. The control module controls the ventilation and temperature control system to enable the in-vehicle cooling mode to cool the vehicle. When the user operates through the operation panel, the ventilation and temperature control system can determine that there are passengers inside the vehicle.

[0087] Therefore, when the air quality parameter outside the vehicle is not within the second preset air quality parameter range, it indicates that the air quality outside the vehicle is poor, and the air conditioner switches to the internal circulation. When the air conditioner switches to the internal circulation, the carbon dioxide sensor detects the carbon dioxide concentration inside the vehicle in real time. When the carbon dioxide concentration reaches 0.1%, it is fed back to the control module, and the control module controls the air conditioner to turn on the external circulation working mode. At this time, even if the air quality outside the vehicle still does not meet the standard, the air conditioner is kept in the external circulation working mode to ensure the safety of the passengers inside the vehicle.

[0088] In some embodiments of the present application, the control method also includes: when the ventilation and temperature control system enables the in-vehicle ventilation mode, the air conditioner is controlled to be turned on, and the working mode of the air conditioner is the external circulation mode, and the timing is started at the same time as the air conditioner is turned on. When the accumulated timing reaches a second preset time value, the air conditioner is controlled to be turned off.

[0089] Among them, the in-car ventilation mode means that the user is located inside the vehicle and sends instructions to the control module by operating the operation panel in the vehicle that can communicate with the control module. The control module controls the ventilation and temperature control system to enable the in-car ventilation mode to ventilate the interior of the vehicle.

[0090] It should be noted that the second preset time can be set according to the user's usage requirements, and the user can also turn off the in-car ventilation mode at any time according to his or her own usage requirements (such as when the accumulated time does not reach the second preset time value).

[0091] In a further embodiment of the present application, when the in-vehicle ventilation mode is turned on, the air conditioner turns on the external circulation and enables the face blowing mode, and the gear position of the face blowing mode can be set. Among them, the gear position of the face blowing mode can be set to the highest gear position by default.

[0092] In some embodiments of the present application, when the in-vehicle ventilation mode is enabled, the carbon dioxide sensor detects the carbon dioxide concentration inside the vehicle in real time. When the concentration reaches 0.1%, a feedback signal is sent to the control module. The control module controls the start of the air conditioner external circulation working mode again, and uses the timing module to start the timing. When the timing module reaches the preset time, the air conditioner is turned off.

[0093] It is understandable that when the user enables the in-car ventilation mode when resting in the car after parking, in order to prevent the user from carbon dioxide poisoning, the carbon dioxide concentration inside the vehicle needs to be detected in real time through a carbon dioxide sensor, and the in-car ventilation mode needs to be enabled cyclically to prevent the carbon dioxide concentration inside the vehicle from being too high, thereby improving the safety of the ventilation and temperature control system.

[0094] In some embodiments of the present application, the control method further includes: when the ventilation and temperature control system enables the in-vehicle heating mode, controlling to turn on the infrared sensor, the far-infrared heating device and the carbon dioxide sensor.

[0095] Specifically, the control module obtains the real-time temperature inside the vehicle detected by the infrared sensor, and controls the heating power of the far-infrared heating device according to the real-time temperature. At the same time, the control module obtains the carbon dioxide concentration inside the vehicle detected by the carbon dioxide sensor in real time, and compares the carbon dioxide concentration with the second preset concentration value. When the carbon dioxide concentration is not lower than the first preset concentration value, the air conditioner is controlled to start the external circulation mode.

[0096] The in-car heating mode means that the user is inside the vehicle and sends instructions to the control module by operating the operation panel. The control module controls the ventilation and temperature control system to enable the in-car heating mode to adjust the temperature inside the vehicle. When the far-infrared heating device is turned on, the temperature inside the vehicle can be increased.

[0097] Specifically, when the in-vehicle heating mode is enabled, the far-infrared heating device can communicate with the temperature sensor. When the far-infrared heating device is turned on, a signal can be sent to the temperature sensor. The temperature sensor turns on and detects the internal temperature of the vehicle in real time. The control module can control the heating power of the far-infrared heating device according to the real-time temperature inside the vehicle.

[0098] Among them, when the in-car heating mode is enabled, the far-infrared heating device can be started at the maximum heating power to quickly increase the temperature inside the vehicle. At the same time, the temperature sensor detects the temperature inside the vehicle in real time. When the temperature reaches the preset temperature value, it can feedback the signal to the control module and the timing module. The control module can adjust the power of the far-infrared heating device in real time according to the signal of the temperature sensor to ensure the stability of the temperature inside the vehicle. The timing module can synchronize the timing. When the preset time is reached, the timing module can send a signal to the control module, and the control module controls to turn off the far-infrared heating device.

[0099] In some embodiments of the present application, when the air conditioner is turned on in external circulation mode, the control method also includes: controlling the dew point sensor to be turned on, and obtaining the dew point parameters of the vehicle's windshield and door glass detected in real time by the dew point sensor; when the dew point parameters reach the preset dew point, controlling the air conditioner's working mode to switch to the defrost mode to prevent the windshield and door glass from fogging.

[0100] Among them, when the in-car heating mode is enabled, the carbon dioxide sensor is turned on. The carbon dioxide sensor can detect the carbon dioxide concentration inside the vehicle in real time. When the carbon dioxide concentration reaches the preset concentration value (such as 0.1%), the feedback signal is sent to the control module. The control module controls the air conditioner to start the external circulation working mode, and turns off the air conditioner after the air conditioner has been in the external circulation mode for a period of time to prevent the carbon dioxide concentration inside the vehicle from being too high and improve the working reliability of the ventilation and temperature control system.

[0101] It should be noted that the working time of any working link in the above-mentioned multiple working modes can be designed by the user. The user can set it according to the start-up time of components such as the air conditioner and the far-infrared heating device to adjust the preset time value compared with the accumulated time of the timing module.

[0102] Reference Figure 1 The control module can also communicate with the air conditioner, air quality sensor, infrared sensor, negative ion sensor, electric compressor, far-infrared heating device, indoor temperature sensor (can be used to detect the temperature inside the vehicle) and timer (timing device).

[0103] The air conditioner can communicate with the air quality sensor, indoor temperature sensor and door lock sensor. The air quality sensor can also communicate with the indoor temperature sensor and the fragrance system. When the air quality sensor detects that the air quality in the car is poor, it can feedback the signal to the fragrance system and the control module. The fragrance system can emit fragrance to improve the smell in the car. At the same time, the control module can control the negative ion sensor to generate negative ions to improve the air quality in the car.

[0104] The door lock sensor can also communicate with the fragrance system and can feedback a signal to the fragrance system when a door opening signal is detected. The fragrance system can emit fragrance into the interior of the vehicle to improve the smell inside the vehicle and enhance the user experience when entering the vehicle.

[0105] The timer can communicate with the indoor temperature sensor, far-infrared heating device and dew point sensor. The above devices can feedback signals to the timer. The timer can start timing according to the signal and can feed back the accumulated time to the control module to time the working time of multiple devices through the timer.

[0106] The indoor temperature sensor can also communicate with the far-infrared heating device. When the indoor temperature sensor detects that the temperature inside the car reaches the temperature set by the user, it can feedback a signal to the control module to adjust the power of the infrared heating device in real time through the control module.

[0107] Furthermore, the infrared sensor can also communicate with the carbon dioxide sensor. When the infrared sensor detects the presence of a person inside the vehicle, it can feed back a signal to the carbon dioxide sensor so as to detect the carbon dioxide concentration inside the vehicle through the carbon dioxide sensor. The carbon dioxide sensor can communicate with the control module to feed back the carbon dioxide concentration inside the vehicle to the control module. The control module can control the operation mode of the air conditioner according to the carbon dioxide concentration. The control module can also control the carbon dioxide sensor to detect the carbon dioxide concentration inside the vehicle in real time according to the operation mode of the ventilation and temperature control system.

[0108] Therefore, through communication between the above-mentioned multiple devices and communication between the multiple devices and the control module, the above-mentioned in-vehicle cooling mode, in-vehicle heating mode, in-vehicle ventilation mode, outside-vehicle cooling mode, outside-vehicle heating mode and outside-vehicle ventilation mode can be realized.

[0110] In some embodiments of the present application, when the vehicle is in the in-vehicle ventilation mode or the out-vehicle ventilation mode, the rain sensor is turned on to detect whether it is raining. When it is not raining, the window switch controls the window to open, and the vehicle can be ventilated through the window and the air conditioner at the same time, thereby improving the ventilation efficiency; when it is raining, the window is not opened, and the vehicle is ventilated only through the air conditioner.

[0111] According to the ventilation and temperature control system for a vehicle according to the embodiment of the present application, the ventilation and temperature control system includes: a solar cell, a storage battery, and a control module.

[0114] Among them, through communication and cooperation between multiple devices, multiple working modes of the ventilation and temperature control system are realized. The ventilation and temperature control system includes: in-vehicle cooling mode, in-vehicle heating mode, in-vehicle ventilation mode, outside-vehicle cooling mode, outside-vehicle heating mode and at least two of the outside-vehicle ventilation mode. Any two working modes can be switched with each other.

[0115] In some embodiments of the present application, the far-infrared heating device includes a far-infrared radiation tube and a reflection device, and the far-infrared radiation tube and the reflection device are arranged in the upper area of ​​the foot accommodating area of ​​the main driver's seat and the co-driver's seat and the skylight area, so that the passenger compartment is heated more evenly and the heating speed is faster.

Among them, the fragrance box can select a corresponding fragrance type according to the instruction to emit fragrance, and the fragrance type and concentration can be customized according to the needs of the user.

[0118] In some embodiments of the present application, the ventilation and temperature control system also includes: a rain sensor, which is used to detect whether it is raining. When it is not raining, the window switch controls the windows to open. At this time, the vehicle can be ventilated through the windows and the air conditioner at the same time, thereby improving the ventilation efficiency; when it is raining, the windows are not opened, and the vehicle is only ventilated through the air conditioner.

[0119] Reference Figure 3 The battery in the ventilation and temperature control system can be used to supply power to the window switch, rain sensor and air conditioning system to meet the needs of opening and closing the window switch, detecting whether it is raining by the rain sensor and operating the air conditioning system.

[0120] In a specific embodiment of the present application, the window switch and the rain sensor can communicate with the time relay respectively.

The air conditioning controller can control the working mode of the compressor and the internal and external circulation damper according to the temperature inside the car. For example, when the indoor temperature sensor detects that the temperature inside the vehicle is higher than the preset temperature value, the air conditioning controller controls the compressor to start, and the internal and external circulation damper to start the internal circulation working mode to cool the vehicle. When the temperature inside the vehicle drops to the preset temperature, the air conditioning system can stop working.
