[0075] Based on the above vehicle air exchange system, the embodiment of the present application further provides a remote control method of the vehicle air exchange system, as shown in Figure 2 The method comprises the following steps.

[0076] S101: The vehicle air exchange system self-checks to determine whether the system opening requirements are met.

[0077] When the vehicle gear is in P or N and the vehicle power state is off, the vehicle air exchange system (hereinafter referred to as "system") self-checks, and the self-checking range includes the input unit, the decision unit and the execution unit. After the self-checking is completed, if the system meets the opening requirements, the air exchange function is available, and if the system does not meet the opening requirements, the air exchange function is not available.

[0078] S102: Obtain the parameter information corresponding to the system working mode.

[0080] a) Working mode: manual mode, reservation mode, automatic mode;

[0088] i) Threshold information: PM2.5 concentration, air humidity.

[0089] S103: Based on the parameter information corresponding to the working mode, the air exchange function is realized in combination with the vehicle external environment information.

[0090] It is mentioned above that the principles of the three working modes are different, and the corresponding parameter information is not completely consistent, so the system has different processing methods for different working modes, which will be introduced in detail below. It is worth noting that the following introduction is based on the fact that all the sensor monitoring switches mentioned in step S102 are enabled, i.e., the "rain sensor monitoring switch enable state", "rain sensor real-time monitoring switch enable state", "PM2.5 sensor timing monitoring switch enable state", and "air humidity sensor timing monitoring switch enable state" are all enabled.

[0091] Mode one: Based on the parameter information corresponding to the manual mode, the air exchange function is realized in combination with the vehicle external environment information.

[0092] S1-1: Monitor the rainfall information through the rain sensor.

[0093] Through the rain sensor, it is monitored whether it is raining or not. If it is raining, the air exchange function is not started, and if it is not raining, the air exchange function is started, and then step S1-2 is executed.

[0094] S1-2: Determine whether the opening time of the air exchange function reaches the predetermined closing time.

[0095] Determine whether the opening time of the air exchange function reaches the predetermined closing time. The predetermined closing time is set to 12 hours. If it has reached, the air exchange function is closed, and it will not be automatically started again. If it has not reached, step S1-2 is executed to determine whether the predetermined closing time has been reached.

[0096] In the execution of steps S1-1-S1-2, the rainfall information is monitored in real time by the rainfall sensor, the PM2.5 concentration is monitored at regular intervals by the PM2.5 sensor, and the air humidity is monitored at regular intervals by the air humidity sensor. If any of the following conditions is met: it is raining, the PM2.5 concentration is greater than a threshold value, and the air humidity is greater than a threshold value, the execution of the above steps is stopped, the air exchange function is closed, and it will not be automatically turned on again. At the same time, if the air exchange function is manually triggered to be closed or it is monitored that the vehicle power state is on, the execution of the above steps is also stopped, the air exchange function is closed, and it will not be automatically turned on again.

[0097] Mode two: based on the parameter information corresponding to the reservation mode, combined with external environment information, to realize the air exchange function.

[0098] S2-1: monitor the rainfall information by the rainfall sensor.

[0099] The rainfall sensor is used to monitor whether it is raining. If it is raining, the air exchange function is not turned on. If it is not raining, the air exchange function is turned on, and then step S2-2 is executed.

[0100] S2-2: determine whether the current time reaches the closing time of the single time period.

[0101] The single time period refers to the "single time period in the reservation mode" mentioned in step S102. If the current time reaches the closing time of the single time period, the air exchange function is closed and will not be automatically turned on again. If it does not reach, step S2-2 is executed at regular intervals to determine whether the closing time of the single time period has been reached.

[0102] In the execution of steps S2-1-S2-2, the rainfall information is monitored in real time by the rainfall sensor, the PM2.5 concentration is monitored at regular intervals by the PM2.5 sensor, and the air humidity is monitored at regular intervals by the air humidity sensor. If any of the following conditions is met: it is raining, the PM2.5 concentration is greater than a threshold value, and the air humidity is greater than a threshold value, the execution of the above steps is stopped, the air exchange function is closed, and it will not be automatically turned on again. At the same time, if the air exchange function is manually triggered to be closed or it is monitored that the vehicle power state is on, the execution of the above steps is also stopped, the air exchange function is closed, and it will not be automatically turned on again.

[0103] Mode three: based on the parameter information corresponding to the automatic mode, combined with external environment information, to realize the air exchange function.

[0104] S3-1: monitor the rainfall information by the rainfall sensor.

[0105] The rainfall sensor is used to monitor whether it is raining. If it is raining, the air exchange function is not turned on. If it is not raining, the air exchange function is turned on, and then step S3-2 is executed.

[0106] S3-2: judging whether the current time reaches the closing time of the current cycle time period.

[0107] The cycle time period refers to the cycle time period in the automatic mode mentioned in step S102. It is judged whether the current time reaches the closing time of the current cycle time period. If it has reached, the air exchange function is closed, and then step S3-3 is executed. If it has not reached, step S3-2 is executed to judge whether the closing time of the current cycle time period has reached.

[0108] S3-3: judging whether the current time reaches the opening time of the next cycle time period.

[0109] It is judged whether the current time has reached the opening time of the next cycle time period. If it has reached, the air exchange function is opened again. If it has not reached, step S3-3 is executed to judge whether the opening time of the next cycle time period has reached.

[0110] In the process of executing steps S3-1-S3-3, the rain information is monitored by the rain sensor in real time, the PM2.5 concentration is monitored by the PM2.5 sensor in real time, and the air humidity is monitored by the air humidity sensor in real time. If any of the following conditions is met, the air exchange function is closed, and then steps S3-1-S3-3 are executed again: it rains, the PM2.5 concentration is greater than a threshold, and the air humidity is greater than a threshold. At the same time, in this process, if the air exchange function is manually triggered to be closed, or it is monitored that the vehicle power state is on, the air exchange function is also closed, and then steps S3-1-S3-3 are executed again.

[0111] The above is the specific execution steps for the three modes. If the sensor monitoring switch mentioned in step S102 is partially enabled, the above steps are sequentially executed based on the partially enabled parameters, for example: if only the PM2.5 sensor monitoring switch is turned on, after the air exchange function is opened, only the PM2.5 concentration is monitored, and the rain information is no longer monitored by the rain sensor, and the air humidity is no longer monitored by the air humidity sensor.

[0112] Although the present application has been described in detail with reference to the foregoing embodiments, it should be understood by those skilled in the art that the technical solutions recorded in the foregoing embodiments can still be modified, or some technical features can be replaced by equivalent ones. Such modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present application.
