In the embodiment of the present application, the controller 11 may determine whether the actuator 132 may be activated according to the battery level information and the vehicle environment information, and then control the actuator 132 to execute a corresponding control strategy.

In the embodiment of the present application, the controller 11 can obtain the car environment information and the battery power information, and thus when it formulates the actuator control strategy, it can determine whether to start some actuators according to the battery power information. Therefore, the battery power can be consumed to a certain set value, and then certain execution mechanisms are not executed, so that the problem that other core functions of the vehicle cannot be started later due to excessive consumption of the battery power is avoided.

In the specific application of the embodiment of the present application, when the battery power information received by the controller 11 is determined to be higher than the set value, the actuator 132 may be controlled to execute a corresponding control strategy according to the vehicle environment information; when the battery level is lower than the set value, the controller 11 does not trigger the actuator 132 to start, but generates a corresponding prompt message to prompt the user of the reason why the user cannot start the device.

In addition, in practical application, if people exist in the automobile, if the electric quantity of the battery is lower than a certain set value, some execution mechanisms are started to wake up the people in the automobile, and then the problem that the people in the automobile enter a sleep state, and the main execution mechanism of the air conditioner is not started any more, so that safety accidents occur is avoided.

In addition, in other applications of the embodiment of the present application, the controller 11 may also be an air conditioning controller specifically used for controlling an air conditioning system as mentioned in the background of the invention.

Fig. 2 is a schematic structural diagram of another electric vehicle air conditioning system provided in an embodiment of the present application. As shown in fig. 2, compared with the air-conditioning operation system shown in fig. 1, the controller of another electric vehicle air-conditioning control system adopts a vehicle body controller 16, and a power domain controller 15 is added to the vehicle air-conditioning system. The battery management system 12 is directly connected with the power domain controller 15 in a communication mode, and the battery capacity information is sent to the vehicle body controller 16 through the power domain controller 15.

As shown in fig. 2, in the embodiment of the present application, the vehicle air conditioning system may further include a vehicle air conditioner system 14. The in-vehicle system 14 may be an in-vehicle system 14 having a wireless communication device; the vehicle machine system 14 and the power domain controller 15 may be connected by vehicle-mounted ethernet communication. Compared with a CAN bus and a LIN bus, the vehicle-mounted Ethernet has the characteristic of high communication rate, so that some procedural information and instruction information CAN be rapidly issued to the power domain controller 15.

In the embodiment of the present application, the in-vehicle system 14 has a wireless communication device, and is connected to the power domain controller 15. Under the condition that the remote terminal is provided with a program for controlling the starting of the air-conditioning operation system, an air-conditioning starting instruction and a control strategy can be issued to the power domain controller 15 through the vehicle-mounted machine system 14, and then issued to the vehicle body controller 16 through the power domain controller 15, and the vehicle body controller 16 is triggered to start the execution mechanism 132 to work according to the battery electric quantity information and the vehicle environment information and a preset control strategy, so that the remote control of the air-conditioning operation system is realized; in addition, when the program codes in the vehicle body controller 16 and the power domain controller 15 need to be updated (i.e., various control strategies thereof are updated), the program codes may be issued to the power domain controller and the vehicle body controller 16 by the vehicle system 14.

Fig. 3 is a schematic structural diagram of another air conditioning system for an electric vehicle according to an embodiment of the present disclosure, as shown in fig. 3, compared with the air conditioning operation system shown in fig. 1, an air conditioning controller 17 is adopted as a controller of the other air conditioning control system for the electric vehicle, and the air conditioning system for the vehicle further includes a gateway 18, and the battery management system 12 is connected with the air conditioning controller 17 through the gateway 18. In addition, in the embodiment of the present application, the vehicle air conditioning system may further include a telematics box 19, and the telematics box 19 is also connected to the gateway 18; the remote information processing box 19 is used for sending the remote sending data to the air conditioner controller 17 and other devices through the gateway.

In the air-conditioning operation system for the vehicle provided in the embodiment of the present application, the sensor 131 for the air-conditioning operation system 13 may be one or more of the following: an in-car temperature sensor, an out-car temperature sensor, a humidity sensor, an oxygen content sensor, a carbon dioxide sensor and a harmful gas sensor; in which various sensors other than the outside temperature sensor are disposed in the vehicle compartment.

The temperature sensor outside the vehicle is used for measuring the temperature in the carriage and generating temperature information inside the vehicle; the outside temperature sensor is used for measuring the temperature outside the carriage and generating outside temperature information. The humidity sensor is used for measuring the humidity of the air in the carriage to generate the humidity information of the air in the carriage.

The oxygen content sensor is a sensor used for measuring the oxygen content in the carriage to generate oxygen content information; the carbon dioxide sensor is a sensor for measuring the carbon dioxide content in the vehicle compartment to generate carbon dioxide content information. In a particular application, the oxygen content information and/or the carbon dioxide information generated by the oxygen sensor and/or the carbon dioxide sensor may be used to determine whether a problem of too low oxygen and too high carbon dioxide is present in the vehicle cabin.

The harmful gas sensor is a sensor for measuring whether the concentration of harmful gas is in the vehicle cabin or not and generating the concentration information of the harmful gas, wherein the harmful gas can be carbon monoxide. When the harmful gas information generated by the harmful gas sensor indicates carbon monoxide or nitrogen oxide in the vehicle, the environment of the vehicle is in a possible dangerous state (for example, the environment is sealed in an underground parking garage, and the surrounding vehicles are in an idle running state, so that a large amount of insufficiently combusted gas, such as carbon monoxide, is generated).

Fig. 3 is a schematic structural diagram of a part of an actuator 132 of an air conditioning system for a vehicle according to an embodiment of the present application. The actuator 132 described in fig. 3 is used for the following description, and the actuator 132 of the vehicle air-conditioning operation system of the present application is analyzed for the following understanding of the communication connection relationship between the controller 11 and the actuator 132.

As shown in fig. 3, the air conditioning actuator 132 in the embodiment of the present application includes an inner circulation air inlet 20, an outer circulation air inlet 29, a circulation damper 21, a blower 22, an evaporator 23, a hot and cold damper 24, a heater 25, a defrost damper 26, a middle damper 27, and a lower damper 28.

The circulation damper 21 is used to control the opening degrees of the internal circulation intake port 20 and the external circulation intake port 29 so as to adjust the ratio of the internal air and the external air entering the post-processing section. In practical applications, the number of the circulation dampers 21 may be 1 (1 circulation damper 21 controls both the inner circulation intake port 20 and the outer circulation intake port 29), or may be 2 (one circulation damper 21 controls both the inner circulation intake port 20 and the outer circulation intake port 29).

In the embodiment of the present application, the opening of the circulation damper 21 by the set opening degree means that the circulation damper 21 is located between the vehicle interior circulation intake port 20 and the vehicle exterior circulation intake port 29, so that both the vehicle interior circulation intake port 21 and the vehicle exterior circulation intake port 29 are opened by the set opening degree. In practical applications, air conditioning filter elements (not shown) may be disposed at the internal circulation air inlet 20 and the external circulation air inlet 29, or after the circulation damper 21, for filtering particulate matters in the air.

The blower 22 is for driving air flow, and enters the air supply mode control mechanism through the in-vehicle circulation air intake port or the out-vehicle circulation air intake port.

The evaporator 23 is connected in series with a compressor, a condenser, a liquid reservoir and an expansion valve in a refrigeration mechanism in an air-conditioning operation system as a part of the refrigeration mechanism of the air conditioner (other components of the refrigeration mechanism are not shown in fig. 3); when the refrigerating mechanism works, the refrigerant compressed by the refrigerating mechanism is gasified and expanded at the evaporator 23 side to absorb heat, so that the air flow passing through the periphery of the evaporator is cooled; when the temperature of the evaporator 23 is lower than the dew point temperature of the ambient air, water vapor in the ambient air condenses and precipitates and adheres to the surface of the evaporator 23 or the surfaces of the members in the vicinity.

The heater 25 is used for heating the air flow passing through the periphery of the heater so as to increase the temperature of the air flow; in the embodiment of the present application, the heater is a resistive heater 25.

The cold and hot damper 24 can adjust the amount of air flow blown to the heater 25 to adjust the temperature of the air flow.

The defroster damper 26 (i.e., the upper damper), the middle damper 27 and the lower damper 033 are used to distribute, and process, the airflow. When the defrosting air door 26 is opened, the processed air flow blows to the window glass; when the middle air door 27 is opened, the treated air is blown to the upper body or the adjacent area of people in the vehicle; when the lower damper 28 is opened, the treated air is blown toward the lower body or the vicinity of the vehicle occupant.

In addition, the air conditioning system of the electric vehicle in the embodiment of the application can also comprise some prompting components; the notification member may comprise an audible notification member or a vibrator mounted in the vehicle seat. For example, the voice prompt component can be a vehicle-mounted sound box directly connected with the central control system, or a buzzer specially used for sending alarm information; the vibrator may be a vibrator for massage originally used to realize a massage function, which is installed in a vehicle seat; when the vibrator for massage is used as the prompting member, the vibrator for massage is in a maximum power state.

Based on the aforementioned sensor 131 and actuator 132, the vehicle air conditioning operation system in the embodiment of the present application may implement the following control strategy.

In one application, in the case where the sensor 131 is an oxygen content sensor and a carbon dioxide sensor, and the actuator 132 includes the circulation damper 21, the controller 11 may control the opening of the circulation damper 21 to a set opening degree according to the battery power information, the oxygen content information generated by the oxygen content sensor, and the carbon dioxide content information generated by the carbon dioxide sensor. That is, when the oxygen content of the air in the vehicle is too low and the carbon dioxide content is too high, the circulation damper 21 (particularly, the external circulation damper 21) is opened to a predetermined opening degree, and the air containing high oxygen from the outside is introduced into the vehicle compartment.

In another application of the present application, in the case that the sensor 131 is a harmful gas sensor, and the actuator 132 includes a prompting component, the controller 11 may control the prompting component to operate according to the battery power information and the harmful gas concentration information generated by the harmful gas sensor. For example, the controller 11 may control the vehicle-mounted device to play a high decibel warning sound, and may prompt the content of harmful gas in the vehicle by vibrating the massage vibrator at high power.

In another application, where the sensors 131 are an in-vehicle temperature sensor, an out-vehicle temperature sensor, and a humidity sensor, and the actuator 132 includes a cooling mechanism and a heater 25, the controller 11 may control the cooling mechanism and the heater 25 to operate according to the battery level information, the out-vehicle temperature information, the in-vehicle temperature information, and the in-vehicle air humidity information. For example, when the temperature in the vehicle cabin is too high, the controller 11 controls the cooling mechanism to operate to lower the temperature; if the temperature in the vehicle is too low, the controller 11 controls the heater 25 to work to increase the temperature; if the temperature in the vehicle is too low and the humidity is too high, the controller 11 controls the refrigeration mechanism and the heater 25 to work simultaneously; in addition, in practical application, the working state of the defrosting damper 26 can be controlled according to the information of the temperature inside the vehicle, the information of the temperature outside the vehicle and the information of the air humidity inside the vehicle.

In another application, where the sensor 131 is a particulate matter concentration sensor 131 and the actuator 132 includes an air filter, the controller 11 can control the usage status of the air filter based on the particulate matter concentration information generated by the particulate matter concentration sensor 131. For example, if the PM2.5 content in the vehicle is too high, the controller 11 controls the air filter element to filter the air passing through the circulation damper to filter the particulate matter in the air.

It should be noted that when the aforementioned various needs to maintain the flow of air in the vehicle, it is necessary to start the blower operation, and the rotation speed of the blower 22 is specifically set according to the control strategy.

It should also be noted that the various control strategies for actuator 132 described above are known. In practical applications, the controller 11 sets the battery power threshold information in advance, and when the battery power information is greater than the battery power threshold information, the actuator 132 can still be driven to operate; when the battery level is less than the battery level threshold information, the actuator 132 is not driven any more to ensure the necessary requirements of the vehicle. In addition, in practical applications, if the user sleeps after the air conditioner is turned on, the controller 11 may further determine the time that the air conditioner actuator 132 can be used according to the real-time battery power information, and wake the user up with a prompting component when the battery power information is less than the battery power threshold information.

In this embodiment, the controller 11 may set a user rest mode, where the rest mode is a mode in which the user sleeps in the vehicle and turns on the air conditioner. Under the condition that the user has a rest in the vehicle, the user can also set the rest time so as to wake the client through the prompting component after the preset time is reached; when the controller 11 determines the maximum operable time of the air conditioning actuator based on the power information of the battery management system and the environment information generated by the environment sensor, the domain controller sets a selectable set time at the maximum operable time, and the user can set a predetermined time only within the selectable set time.

In the embodiment of the application, a user can send a control instruction to the domain controller through an intelligent terminal such as a central control system or a smart phone, so that the domain controller can make a control strategy of the air conditioner according to the control instruction. In a specific application, a user can set the time for starting the air conditioner, the end time and the like.

In the vehicle according to the embodiment of the application, when the controller 11 is a vehicle body area controller, after entering the resting mode, the vehicle body area controller may control devices such as a vehicle lamp and a wiper of the vehicle to be not automatically started any more, but to be manually started and closed by a user.

In the specific application of the embodiment of the application, the central control system can be connected with intelligent terminals such as a user's smart phone in a wireless communication mode, and the user can remotely set the running time of the vehicle air conditioner.

In a specific application of the embodiment of the application, when the rest time is over and the air-conditioning mechanism exits the execution, the domain controller can also push the exiting information to the intelligent terminal through the central control system.

In practical application, when a user starts the air conditioner to enter a rest mode, the vehicle door can be locked by remote control, but the vehicle does not enter a fortification mode.

In addition, when the electric vehicle that this application embodiment provided is the extended range electric vehicle, when the air conditioner operating system opened and entered the mode of resting, the range controller can not control the range extender and start, avoids appearing because the range extender work and causes the problem that the ambient air oxygen content is too low, carbon monoxide concentration and carbon dioxide concentration are too high.
