Referring to fig. 1, fig. 1 is a schematic flow chart of an intelligent control method for an automotive air conditioner according to an embodiment of the present invention. Wherein, a plurality of air-conditioning air outlets are arranged in the vehicle where the automobile air conditioner is positioned. As shown in fig. 1, the intelligent control method for the automobile air conditioner may include the following steps:

101. when the automobile air conditioner is in an open state, the vehicle-mounted system obtains the passenger seat distribution form of the vehicle by using the sensing equipment arranged in the vehicle where the automobile air conditioner is located.

In the embodiment of the invention, the distribution form of the seats of the passengers can comprise: the main driver is in a single-seat mode, the main driver and the assistant driver are in a riding mode, the main driver and the back seat are in a riding mode, and the assistant driver and the back seat are in a distributed mode; wherein the rear mat may also comprise a left rear mat and/or a right rear mat. In addition, the vehicle in which the automobile air conditioner is located may be a small-sized vehicle, a medium-sized vehicle, a small-sized electric vehicle, a medium-sized electric vehicle, or a medium-sized vehicle, and the like, and therefore, the distribution of seats in the vehicle may be different. It should be noted that, in the embodiments of the present invention, the seats refer to a seating area in the vehicle, and each seat corresponds to one air-conditioning outlet.

It can be understood that three air-conditioning outlets are installed in a general vehicle and respectively correspond to a main driver seat, a secondary driver seat and a rear seat, and four air-conditioning outlets can be installed in a luxury vehicle and respectively correspond to the main driver seat, the secondary driver seat, a left rear seat and a right rear seat, and even five air-conditioning outlets can be installed, and the rear and middle seats are also taken into consideration, so the number of the air-conditioning outlets is not limited by the invention.

In the embodiment of the invention, the air conditioner air outlet comprises a face blowing air outlet and a foot blowing air outlet.

As an alternative implementation, step 101 may include: when the automobile air conditioner is in an open state, the vehicle-mounted system acquires a target detection signal sent by seat pressure sensing equipment and/or image sensing equipment which are arranged in a vehicle where the automobile air conditioner is located; and the vehicle-mounted system identifies whether a person takes the vehicle on each seat in the vehicle according to the target detection signal, so that the passenger seat distribution form of the vehicle is obtained.

The seat pressure sensing device can comprise a plurality of seat pressure sensing devices, and each seat pressure sensing device corresponds to one seat; and the image sensing apparatus may include at least one; if there is only one image sensing device, it is preferable to install the image sensing device at the midpoint of the roof in the vehicle so that each seat in the vehicle can be detected in the full range.

Further, the manner of acquiring the detection signal sent by the seat pressure sensing device and/or the image sensing device installed in the vehicle in which the vehicle air conditioner is located by the vehicle-mounted system may specifically be:

the method comprises the following steps that a vehicle-mounted system acquires a pressure detection signal sent by seat pressure sensing equipment arranged in a vehicle where an automobile air conditioner is located, and the pressure detection signal is used as a target detection signal; or the vehicle-mounted system acquires an image detection signal sent by image sensing equipment arranged in a vehicle where the automobile air conditioner is located, and the image detection signal is used as a target detection signal; or the vehicle-mounted system respectively acquires the pressure detection signal and the image detection signal sent by the seat pressure sensing equipment and the image sensing equipment which are arranged in the vehicle where the automobile air conditioner is located, and the pressure detection signal and the image detection signal are subjected to fusion processing to obtain a target detection signal.

By implementing the embodiment, whether a person sits on each seat in the vehicle can be intelligently detected through a single or combined scheme of the seat pressure sensing device and the image sensing device, so that the distribution form of the seats of the passengers of the vehicle is identified, and the control method of the automobile air conditioner is more intelligent.

102. And the vehicle-mounted system determines a target air-conditioning outlet corresponding to the seat where no person sits from the plurality of air-conditioning outlets according to the passenger seat distribution form.

In the embodiment of the invention, the automobile Air Conditioning system capable of independently opening and closing the Air outlet can be realized by arranging the Air door and the Air door motor capable of controlling the independent opening and closing of the Air door at the root part of the Air outlet in the box body of the Air Conditioning system (HVAC) of the automobile where the automobile Air conditioner is located, or arranging the Air door and the Air door motor capable of controlling the independent opening and closing of the Air door on the Air duct of each Air Conditioning Air outlet of the automobile where the automobile Air conditioner is located.

103. And the vehicle-mounted system controls the air door motor corresponding to the target air-conditioning air outlet to execute a first operation so as to close the air door corresponding to the target air-conditioning air outlet.

In an embodiment of the present invention, the first operation includes: a current position feedback of the damper motor is obtained from the drive output and the position of the damper motor is controlled to switch from the current position to the first target position.

Implementing the method described in fig. 1, when the vehicle air conditioner is in an open state, obtaining a passenger seat distribution form of the vehicle by using the sensing device installed in the vehicle in which the vehicle air conditioner is located, and determining a target air-conditioning outlet corresponding to an unmanned seat from a plurality of air-conditioning outlets installed in the vehicle in which the vehicle air conditioner is located according to the passenger seat distribution form, thereby controlling a damper motor corresponding to the target air-conditioning outlet to perform a first operation so as to close a damper corresponding to the target air-conditioning outlet, and intelligently performing independent closing control on the air-conditioning outlet corresponding to the unmanned seat according to the passenger seat distribution form of the vehicle in which the vehicle air conditioner is located, thereby saving vehicle energy.

Example two

Referring to fig. 2, fig. 2 is a schematic flow chart of another intelligent control method for an automotive air conditioner according to an embodiment of the present invention. As shown in fig. 2, the intelligent control method for the vehicle air conditioner may include the following steps:

201. when the automobile air conditioner is in an open state, the vehicle-mounted system controls the automobile air conditioner to operate at a preset target temperature, a preset target air outlet mode and a preset target air outlet volume according to the internal environment temperature and the external environment temperature of the automobile at the current moment. The preset target air outlet mode comprises a face air outlet mode and/or a foot air outlet mode.

In the embodiment of the invention, the vehicle can be provided with the air conditioner sensing equipment, and the air conditioner sensing equipment can detect the internal environment temperature of the automobile, the external environment temperature of the automobile and the sunlight intensity. Moreover, the automobile air conditioning system based on the air outlet of the air conditioner capable of being independently opened and closed described in the step 102 further has the conditions of stepless adjustable air volume of the blower, stepless adjustable temperature, adjustable air outlet mode and the like.

The preset target temperature and the preset target air outlet volume may be values obtained and preset by developers through a large amount of experimental data summarization.

Optionally, the vehicle-mounted system may control the vehicle air conditioner to output air in a face-blowing air-out mode in summer and to output air in a foot-blowing air-out mode in winter.

As an alternative implementation, step 201 may include: when the automobile air conditioner is in an open state, the vehicle-mounted system controls the automobile air conditioner to enter a heating or cooling working state according to the automobile internal environment temperature and the automobile external environment temperature at the current moment, and operates at a preset target temperature, a preset target air outlet mode and a preset target air outlet volume after the heating or cooling working state is finished.

By implementing the embodiment, the control method of the automobile air conditioner can be more intelligent.

202. The vehicle-mounted system judges whether the external environment temperature of the automobile is within a preset temperature range. If not, go to step 203; otherwise, the flow is ended.

It should be noted that, after the outlet air temperature of the intelligent vehicle air conditioner tends to be stable, the outlet air temperature of the intelligent vehicle air conditioner can be kept at a temperature at which a human body feels comfortable, or the temperature of the vehicle air conditioner manually set by a user is also kept at a temperature at which a human body feels comfortable, so that when the external environment temperature of the vehicle belongs to a preset suitable temperature range, it can be determined that the energy consumption of the vehicle air conditioner is less, and at this time, the vehicle where the vehicle air conditioner is located does not need to enter an energy-saving mode, that is, the air conditioner air outlet corresponding to the seat where no one takes is not required to be independently closed and controlled according to the passenger seat distribution form; otherwise, the energy saving mode is required to be entered, i.e. steps 203-205 are executed.

For example, assume that the predetermined proper temperature range is specifically 23-27 ℃. If the external environment temperature of the automobile is lower than 23 ℃, judging that the external environment temperature of the automobile is too cold, and more energy is needed for heating an automobile air conditioner; or the external environment temperature of the automobile is higher than 27 ℃, and more energy is needed for the refrigeration of the automobile air conditioner, so that the energy-saving mode needs to be entered.

As an optional implementation mode, the vehicle-mounted system can also detect a starting operation instruction of a vehicle master user for the energy-saving mode, and when the starting operation instruction is received, execute steps 203-205.

203 to 205. Steps 203 to 205 are the same as steps 101 to 103 described in the first embodiment, and the embodiment of the present invention is not described herein again.

206. The vehicle-mounted system obtains a passenger carrying plan of a vehicle owner user within a preset time.

In the embodiment of the present invention, the implementation manner of step 206 may specifically be: the vehicle-mounted system acquires a daily trip plan of a vehicle owner user from a user authorization cloud database; obtaining a passenger carrying plan of a vehicle owner user within a preset time according to a daily trip plan; the daily trip plan is sent to the user authorization cloud database by the owner user through the terminal equipment.

The terminal device can be a wearable device, a mobile phone or a tablet computer.

Wherein the daily trip plan includes when, where, what to do, etc.; the passenger pick-up plan comprises when, boarding place, number of passengers and the like; the starting time of the preset time length is the current time, and the starting and stopping time is the time after the preset time length from the current time.

By implementing the implementation mode, the daily trip plan of the owner user can be acquired by adopting a big data technology, and the time when a passenger gets on the vehicle can be known in advance, so that the demand management of regional control in the vehicle can be made in advance.

As another optional implementation manner, when the vehicle air conditioner is in a closed state, the vehicle-mounted system may receive vehicle air conditioner starting information sent by a vehicle owner user through the user authorization cloud server, and when the vehicle air conditioner starting information is received, interpret the vehicle air conditioner starting information to obtain a control instruction of the vehicle air conditioner; and the vehicle-mounted system controls the automobile air conditioner to be switched from the off state to the on state according to the control instruction.

By implementing the implementation mode, the starting of the automobile air conditioner can be remotely controlled in advance, and when the owner user arrives at the automobile, the comfortable environment suitable for a human body is possessed in the automobile.

Alternatively, the implementation of step 206 may specifically be: the vehicle-mounted system sends out inquiry information through a vehicle-mounted screen of the vehicle, and the inquiry information is used for inquiring a daily trip plan of a user of a vehicle owner; and obtaining a passenger carrying plan of the vehicle owner user within a preset time according to the feedback information of the vehicle owner user for the inquiry information.

By implementing the implementation mode, the daily trip plan of the vehicle owner user can be obtained through a Human Machine Interface (HMI) Human Machine interaction system in the vehicle, and the next plan of the vehicle owner user can be actively inquired at any time so as to extract an effective passenger receiving plan.

207. And the vehicle-mounted system judges whether the seats where no people sit corresponding to the target air-conditioning air outlet are seated within the preset time length according to the passenger receiving plan. If yes, go to step 208; otherwise, the flow is ended.

208. The vehicle-mounted system acquires the execution time when the unmanned seat is taken within the preset time length, and calculates the execution time in advance by the preset time quantity to obtain the advanced execution time.

The preset time length and the preset time quantity can be values set in advance by developers.

For example, the preset time duration is 3 hours, the preset time duration is 10 minutes, it is known that a passenger gets on the vehicle after 1 hour according to a passenger pickup plan, when the current time is 12 hours, the execution time of the unmanned seat taken within 3 hours is calculated to be 13, the execution time is advanced by 50 minutes at 12 hours, and then the air door of the target air-conditioning outlet corresponding to the unmanned seat can be opened separately at 12 hours and 50 minutes.

As another optional implementation, the vehicle-mounted system may also obtain a boarding place of the passenger according to the passenger pickup plan, and when it is detected that the vehicle navigation map shows that the vehicle is about to reach the boarding place after a preset amount of time, control the damper motor corresponding to the target air-conditioning outlet to perform the second operation, so as to open the damper corresponding to the target air-conditioning outlet.

209. And the vehicle-mounted system controls the air door motor corresponding to the target air-conditioning air outlet to execute a second operation at the early execution time so as to open the air door corresponding to the target air-conditioning air outlet.
