[0027] In order to enable those skilled in the art to better understand the scheme of the present invention, the technical scheme in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments.

[0028] It should be noted that the terms "first", "second", etc. in the specification and claims of the present invention and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments of the present invention described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units that are clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0029] Example 1

[0030] According to an embodiment of the present invention, an embodiment of a vehicle control method is provided. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer executable instructions, and although a logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from that shown here.

[0031] Figure 1 is a flow chart of a vehicle control method according to an embodiment of the present invention. Figure 1 As shown, the method comprises the following steps:

[0032] Step S102, in response to the vehicle being in a driving state, obtaining a target temperature inside the vehicle.

[0033] The above-mentioned vehicle can be an unmanned vehicle, a manned vehicle, an electric vehicle, a fuel vehicle, a hybrid vehicle, etc., but not limited to these; the driving state can be the current motion state of the vehicle, including but not limited to: starting, acceleration, constant speed, high speed, deceleration, shutdown, braking; the target temperature can be the current temperature inside the vehicle detected by a temperature sensor installed inside the vehicle.

[0034] In an optional embodiment, when the speed sensor installed on the engine detects that the vehicle is in driving state, the air conditioning automatic system can be turned on, the in-vehicle temperature sensor detects and obtains the current in-vehicle temperature, and transmits the data to the vehicle control unit.

[0035] Step S104, acquiring target detection data that matches the target temperature, wherein the target detection data includes one of the following: a first exhaust gas concentration in front of the vehicle, a first oxygen content inside the vehicle, and a target water temperature of the vehicle engine.

[0036] The above-mentioned first exhaust gas concentration can be the exhaust gas concentration of the vehicle in front detected by a concentration sensor installed in front of the vehicle (including but not limited to: carbon monoxide sensor and sulfur dioxide sensor); the first oxygen content can be the oxygen content detected by an oxygen sensor installed inside the vehicle; the vehicle engine can be a device that provides power for the car, and in this embodiment can include but not be limited to: diesel engine, gasoline engine, electric vehicle motor and hybrid power; the target water temperature can be the water temperature collected by the water temperature sensor installed on the engine.

[0037] In an optional embodiment, the suitable temperature inside the vehicle is 24°C, so a temperature range of 12-24°C can be pre-set. When the in-vehicle temperature sensor detects that the current in-vehicle temperature is within the temperature range of 12-24°C, it indicates that the current in-vehicle temperature is suitable, and air conditioning cooling or heating is not required. The concentration sensor can be turned on, and the concentration sensor detects the exhaust concentration (i.e., the first exhaust concentration) discharged by the preceding vehicle, and transmits the first exhaust concentration to the vehicle control unit; when the in-vehicle temperature sensor detects that the current in-vehicle temperature is higher than 24°C, it indicates that the current in-vehicle temperature is high, and the AC (Air Conditioning, air conditioning device) refrigeration system and internal circulation mode can be turned on by the vehicle control unit to ensure the refrigeration effect, and the in-vehicle oxygen sensor is turned on at the same time, and the oxygen sensor detects the oxygen content (i.e., the first oxygen content) in the vehicle, and transmits the first oxygen content to the vehicle control unit; when the in-vehicle temperature sensor detects that the in-vehicle temperature is lower than 12°C, it indicates that the current in-vehicle temperature is low, and the engine water temperature sensor is turned on, and the engine water temperature sensor detects the current water temperature (i.e., the target water temperature), and transmits the target water temperature to the vehicle control unit.

[0038] For example, when the in-car temperature sensor detects that the in-car temperature is 20°C, the concentration sensor is turned on, the concentration sensor detects the exhaust concentration discharged by the vehicle in front, and transmits the first exhaust concentration data to the vehicle control unit; when the in-car temperature sensor detects that the in-car temperature is 35°C, the vehicle control unit turns on the AC refrigeration system and the internal circulation mode, and turns on the in-car oxygen sensor at the same time, the oxygen sensor detects the oxygen content in the car (ie, the first oxygen content), and transmits the first oxygen content to the vehicle control unit; when the in-car temperature sensor detects that the in-car temperature is 8°C, the engine water temperature sensor is turned on, the engine water temperature sensor detects the current water temperature, and transmits the target water temperature to the vehicle control unit.

[0039] Step S106, determining the operating mode of the air conditioner on the vehicle based on the target detection data.

[0040] The above-mentioned air conditioner can be a car air conditioner, which is composed of a compressor, a condenser, a throttling element, an evaporator, a fan and necessary control components, and is used to adjust the temperature and humidity in the car; the working mode can be the working mode of the car air conditioner, which includes but is not limited to: internal circulation mode, external circulation mode, heating mode, cooling mode, internal and external circulation mode, defrost mode, automatic circulation mode.

[0041] In an optional embodiment, when the temperature sensor transmits data to the vehicle control system, if the target temperature is between 12-24°C, the vehicle control system turns on the concentration sensor, the concentration sensor detects the exhaust gas, and transmits the first exhaust gas concentration data to the vehicle control system. If the first exhaust gas concentration is greater than the preset exhaust gas concentration, the air conditioning working mode is determined to be internal circulation. If the first exhaust gas concentration is less than or equal to the preset exhaust gas concentration, it is determined to be external circulation mode. If the target temperature is higher than 24°C, the vehicle control system turns on the AC refrigeration system and the internal circulation mode, and turns on the oxygen sensor at the same time. The oxygen sensor transmits the detected oxygen content to the whole vehicle control system. The vehicle control unit detects the first oxygen content and compares it with the preset oxygen content. If the first oxygen content is greater than or equal to the preset value, the air-conditioning working mode is determined to be the internal circulation mode and the cooling mode. If the first oxygen content is less than the preset value, the working mode is determined to be the external circulation mode. If the target temperature is lower than 12°C, the vehicle control system turns on the engine water temperature sensor. When the engine water temperature sensor detects that the water temperature exceeds 60°C, the vehicle control system determines that the air-conditioning system turns on the heating mode and the internal circulation mode. If the engine water temperature reaches 90°C, the humidity sensor in the car detects the air humidity in the car, and the air-conditioning system determines the defrost mode for the windows and determines the internal and external circulation of the car.

[0042] Step S108, controlling the operation of the air conditioner based on the working mode.

[0043] In an optional embodiment, after various sensors send detection data to the vehicle control unit, the vehicle control unit determines the working mode of the air conditioner based on the target detection data. If the determined working mode is the internal circulation mode, the vehicle control unit sends a command to the control module to control the damper switching, close the external circulation of the air conditioner, prevent the outside gas from entering the car, and start the internal circulation mode; if the determined working mode is the external circulation mode, the control module turns on the air conditioning system, starts the external circulation mode, and realizes the exchange of air inside the car with fresh air outside the car; if the determined working mode is the heating mode, the gear position changes with the temperature inside the car; the entire system control is adjusted and switched according to the real-time detection data, and the control module sends instructions to control the various air conditioning modes to switch and coordinate with each other.

[0044] Through the above steps, in response to the vehicle being in a driving state, the target temperature inside the vehicle is obtained, and the target detection data matching the target temperature is further obtained. Further based on the target detection data, the working mode of the air conditioner on the vehicle is determined, and the air conditioner operation is further controlled based on the working mode. It is easy to notice that the working mode of the air conditioner is determined based on the temperature inside the vehicle and the matching target detection data, wherein the target detection data includes one of the following: a first exhaust gas concentration in front of the vehicle, a first oxygen content inside the vehicle, and a target water temperature of the vehicle engine, so that the working mode of the air conditioner can be automatically controlled according to the air quality inside and outside the vehicle, achieving the technical effect of real-time detection of the air quality inside the vehicle and starting the corresponding equipment to maintain a better air quality inside the vehicle, thereby solving the technical problem of low driving safety caused by poor air quality inhaled by people in the vehicle in the related technology.

[0045] In the above embodiment of the present invention, obtaining target detection data matching the target temperature includes: in response to the target temperature being within a preset temperature range, obtaining a first exhaust gas concentration; in response to the target temperature being greater than the maximum value of the preset temperature range, obtaining a first oxygen content; in response to the target temperature being less than the minimum value of the preset temperature range, obtaining a target water temperature.

[0046] The above-mentioned preset temperature range may be a preset suitable temperature range in the vehicle, for example, the preset temperature range may be 12-24° C., but is not limited thereto and may be set by the user.

[0047] Specifically, the in-car temperature sensor determines the temperature in the car. When the detected in-car temperature is between 12-24°C, the vehicle control unit sends a command to the concentration sensor, and the concentration sensor detects the exhaust gas concentration of the vehicle in front to obtain a first exhaust gas concentration; when the detected in-car temperature is higher than 24°C, the vehicle control unit sends a command to the in-car oxygen sensor, and the oxygen sensor detects the oxygen content in the car to obtain a first oxygen content; when the detected in-car temperature is lower than 12°C, the vehicle control unit sends a command to the engine water temperature sensor to detect the water temperature to obtain the target water temperature.

[0048] Optionally, in response to the target monitoring data including a first exhaust gas concentration, the operating mode of the air conditioner on the vehicle is determined based on the target detection data, including: in response to the first exhaust gas concentration being greater than a preset exhaust gas concentration, determining that the operating mode is an internal circulation mode; in response to the first exhaust gas concentration being less than or equal to a preset exhaust gas concentration, determining that the operating mode is an external circulation mode.

[0049] The above-mentioned preset exhaust gas concentration can be a pre-set exhaust gas concentration indicating that the air quality outside the vehicle is poor, and can be set by the user. The present invention does not impose any limitation on the specific numerical value; the internal circulation mode can be to close the air flow channels inside and outside the vehicle, and complete the air flow circulation by turning on the fan, and the inhaled air flow only comes from the inside of the vehicle, effectively blocking the external dust and harmful gases from entering the vehicle; the external circulation mode can be to suck the external fresh air into the vehicle through the blower, and then discharge it from the exhaust port at the rear of the vehicle to replenish the fresh air in the vehicle.

[0050] Specifically, the concentration sensor detects the exhaust gas emitted by the vehicle in front, transmits the information to the vehicle control unit, and issues a command to the control module to control the switching of the damper. If the exhaust gas concentration is greater than the preset exhaust gas concentration, the air-conditioning mode is determined to be the internal circulation mode to prevent the exhaust gas from entering the vehicle. When the exhaust gas concentration is less than or equal to the preset exhaust gas concentration, the air-conditioning mode is determined to be the external circulation mode to achieve the exchange of air inside the vehicle and fresh air outside the vehicle.

[0051] Further, based on the target detection data, determining the operating mode of the air conditioner on the vehicle includes: in response to the vehicle being in a running state, determining the operating mode based on the first exhaust gas concentration.

[0052] Specifically, when the concentration sensor detects that the exhaust gas discharged by the preceding vehicle is greater than a preset exhaust gas concentration, the operating mode is determined to be the internal circulation mode; if it is less than or equal to the preset exhaust gas concentration, the operating mode is determined to be the external circulation mode.

[0053] Optionally, in response to the target monitoring data including a first oxygen content, the operating mode of the air conditioner on the vehicle is determined based on the target detection data, including: in response to the first oxygen content being greater than or equal to a first preset oxygen content, determining that the operating mode includes an internal circulation mode and a refrigeration mode; in response to the first oxygen content being less than the first preset oxygen content, determining that the operating mode is an external circulation mode.

[0054] The above-mentioned first preset oxygen content can be a pre-set oxygen content indicating that the air inside the vehicle is not circulating. For example, the first preset oxygen content can be 80%, but is not limited to this and can be set by the user; the cooling mode can be that the air conditioner turns on the AC cooling function to make the blown wind cold air.

[0055] Specifically, the oxygen sensor in the car detects the oxygen content in the car. When the oxygen content in the car is higher than 80%, the working mode is determined to be the internal circulation mode, and the AC cooling mode is turned on at the same time. When the oxygen content in the car is lower than 80%, the working mode is determined to be the external circulation mode. When the oxygen content in the car is higher than 80%, it switches to the internal circulation to ensure that the air quality in the car meets the standards.

[0056] Optionally, in response to the target monitoring data including the target water temperature, the operating mode of the air conditioner on the vehicle is determined based on the target detection data, and also includes: in response to the target water temperature being greater than or equal to the first preset water temperature, determining that the operating mode includes a heating mode and an internal circulation mode; in response to the target water temperature being less than the second preset water temperature, determining that the operating mode includes at least an internal and external circulation mode.

[0057] The above-mentioned first preset water temperature can be a preset engine water temperature indicating that air conditioning heating can be performed. For example, the first preset water temperature can be 60°C, but is not limited to this, and can be set by the user; the second preset water temperature can be a preset engine water temperature indicating that defrost operation can be performed. For example, the first preset water temperature can be 90°C, but is not limited to this, and can be set by the user; the heating mode can be that the air outlet of the air conditioner is hot air, and the gear is changed according to the temperature inside the car.

[0058] Specifically, when the engine water temperature sensor detects that the water temperature is greater than or equal to 60°C, the vehicle control unit issues a command to determine the working mode as heating mode and internal circulation mode, among which the heating mode gears 1, 2, and 3 can be automatically controlled according to the temperature inside the vehicle; when the water temperature is greater than or equal to 90°C, the working mode is determined to be internal and external circulation mode, and the humidity sensor and concentration sensor in the vehicle will also be turned on for real-time monitoring, and the working mode of the air conditioner will be determined based on the data.

[0059] Further, in response to the target water temperature being greater than or equal to the second preset water temperature, the method further includes: acquiring a target air humidity inside the vehicle; and in response to the target air humidity being greater than the preset air humidity, determining that the operating mode further includes a defrost mode.

[0060] The above-mentioned target air humidity may be the humidity value inside the vehicle detected by a humidity sensor installed inside the vehicle; the preset air humidity may be a pre-set air humidity value indicating that the humidity inside the vehicle is high and a defrost operation is required; the defrost mode may be a mode for removing frost on the surface of the air conditioner outdoor unit condenser when the air conditioner heating mode is turned on.

[0061] Specifically, when the engine water temperature reaches 90 degrees, the humidity sensor in the car detects the air humidity in the car. When the air humidity in the car is greater than the preset air humidity, the air conditioning system defrosts the windows and starts the internal and external circulation mode.

[0062] Optionally, after determining that the working mode includes at least an internal and external circulation mode, the method further includes: obtaining a second exhaust gas concentration in front of the vehicle; in response to the second exhaust gas concentration being greater than a preset exhaust gas concentration, determining that the working mode is switched from the internal and external circulation mode to the internal circulation mode.

[0063] The second exhaust gas concentration mentioned above may be the exhaust gas concentration of the vehicle in front detected by a concentration sensor (including but not limited to: a carbon monoxide sensor and a sulfur dioxide sensor) installed in front of the vehicle.

[0064] Specifically, if it is detected that the exhaust concentration of automobiles outside the vehicle is greater than the preset exhaust concentration, the external circulation mode will be closed in time and only the internal circulation mode will be turned on. When the external air quality is lower than the preset exhaust concentration, the external circulation mode will be turned on again.

[0065] Combine the following Figure 2 A preferred embodiment of the present invention is described in detail. Figure 2 As shown, the system includes intelligent air conditioning control and conventional manual operation. After the intelligent air conditioning control is turned on, the default manual operation is invalid. By pressing the air conditioning smart start button, the intelligent control air conditioning mode is turned on, and then the driving state of the vehicle is judged. When the engine speed sensor detects that the car is running, the in-car temperature sensor is further turned on to detect the current in-car temperature and determine the target temperature. When the target temperature is between 12-24°C, the concentration sensor is turned on, and the concentration sensor transmits the data to the vehicle control unit. If the first exhaust gas concentration is greater than the preset exhaust gas concentration, the air conditioning working mode is determined to be the internal circulation mode. If the first exhaust gas concentration is less than or equal to the preset exhaust gas concentration, it is determined to be the external circulation mode. When the target temperature is higher than 24°C, the vehicle control unit turns on the AC cooling mode and the internal circulation mode, and turns on the in-car oxygen sensor at the same time. If the oxygen content in the car is higher than 80%, the working mode is determined to be the internal circulation mode. If the oxygen content in the car is lower than 80%, the working mode is determined to be the external circulation mode. When the target temperature is lower than 12°C, the vehicle control unit sends a command to the engine water temperature sensor to detect the water temperature. If the water temperature is greater than or equal to 60°C, the vehicle control unit issues a command to determine the working mode as heating mode and internal circulation mode, among which the heating mode gears 1, 2, and 3 can be automatically controlled according to the temperature in the car; when the water temperature is greater than or equal to 90°C, the working mode is determined to be the internal and external circulation mode. At the same time, the humidity sensor and concentration sensor in the car will be turned on for real-time monitoring, and the working mode of the air conditioner will be determined based on the data, and the internal and external circulation modes will be switched in real time based on the detection data, and the relevant cooling or heating mode will be turned on, so that the air quality in the car is better than the air quality outside the car.

[0066] Optionally, the method also includes: in response to the vehicle being in an ignition-off state, starting the vehicle's electronic control system based on a preset activation cycle; detecting whether there is a target object inside the vehicle through the electronic control system; in response to the presence of the target object inside the vehicle, obtaining a second oxygen content inside the vehicle; and controlling the vehicle's windows based on the first oxygen content inside the vehicle.

[0067] The above-mentioned flameout state may be a vehicle state in which the engine suddenly stops working; the preset activation period may be a pre-set period for automatic activation of the vehicle's electronic control system, for example, it may be half an hour, but is not limited to this, and may be set by the user; the electronic control system may be an automotive electronic control system, which is basically composed of sensors, electronic controllers, drivers, and control program software, and is used in conjunction with the mechanical system of the vehicle, and uses cables or radio waves to transmit information to each other, thereby performing "electromechanical integration"; the target object may be the driver of the vehicle or a passenger; the second oxygen content may be the oxygen content detected by an oxygen sensor installed inside the vehicle in the flameout state.

[0068] Specifically, in the embodiment of the present invention, the flowchart of vehicle control in the ignition off state is as follows: Figure 3 As shown, when the car is in the off state, the vehicle electronic control system is set to automatically activate every half an hour, and the seat pressure sensor is used to detect whether there is someone in the car. When it is detected that there is someone in the car, the oxygen content in the air in the car is detected by the car oxygen sensor. When the oxygen content is lower than the limit value, that is, the first oxygen content inside the vehicle is lower than 50%, the window lift sensor receives the command from the vehicle control unit, the window opens, and fresh air enters the car.

[0069] Furthermore, the vehicle windows are controlled based on a first oxygen content inside the vehicle, including: in response to the first oxygen content inside the vehicle being less than a second preset oxygen content, controlling the windows to open; in response to the first oxygen content inside the vehicle being greater than or equal to the second preset oxygen content, controlling the windows to close.

[0070] The second preset oxygen content mentioned above may be a preset oxygen content in the vehicle indicating that there is less oxygen inside the vehicle. For example, the second preset oxygen content may be 50%, but is not limited thereto and may be set by the user.

[0071] Specifically, when the oxygen content in the ignition off state is lower than 50%, the windows are controlled to open, and when the oxygen content in the ignition off state is higher than 50%, the windows are controlled to close.

[0072] Optionally, the method further includes: in response to the absence of a target object inside the vehicle, controlling the electronic control system to shut down.

[0073] Specifically, if the seat pressure sensor detects that there is no one in the vehicle, the electronic control system is controlled to be shut down.

[0074] Example 2

[0075] According to an embodiment of the present invention, a vehicle control device is provided. The device can execute the vehicle control method in the above embodiment, and the specific implementation method and preferred application scenario are the same as those in the above embodiment, which will not be described in detail here.

[0076] Figure 4 is a schematic diagram of the structure of a vehicle control device according to an embodiment of the present invention. Figure 4 As shown, the device includes the following parts: a first acquisition module 40 , a second acquisition module 42 , a determination module 44 , and a control module 46 .
