An embodiment of the invention provides a method for controlling the safety of air quality in a vehicle, and referring to fig. 2, fig. 2 is a schematic flow diagram of a first embodiment of the method for controlling the safety of air quality in the vehicle.
In this embodiment, the method for controlling the quality safety of air in a vehicle includes the following steps:
step S10: when a current vehicle is static, acquiring oxygen concentration data acquired by an oxygen concentration sensor in the current vehicle;
it should be noted that, when a current vehicle is detected, the speed of the current vehicle is obtained in real time, whether the speed of the current vehicle is zero or not is judged, when the speed of the current vehicle is zero, the current vehicle is judged to be in a static state, and then sleeper weight data collected by a sleeper weight sensor at a preset position of the current vehicle and/or seat weight data collected by a seat weight sensor are obtained.
It should be understood that when the sleeper weight data collected by the sleeper weight sensor and/or the seat weight data collected by the seat weight sensor satisfy a preset weight threshold, the oxygen concentration sensor provided in the current vehicle automatically collects the oxygen concentration data.
In addition, it should be noted that the current vehicle contains a fresh air system controller, an oxygen concentration sensor, a fresh air channel electromagnetic valve, a seat sensor and a sleeper sensor, wherein the fresh air system controller is automatically in an electrified state when the vehicle is static and when a person is judged to be in the vehicle, so that resources are not wasted, the air quality in the current vehicle is monitored at all times in the electrified state, the fresh air system controller has CAN signal transceiving and processing capabilities, and the fresh air channel is arranged at an inlet and an outlet close to the indoor circulation of the heater, so that received data are more sensitive.
Step S20: judging whether the oxygen concentration data meet a preset threshold range or not;
it should be noted that different threshold ranges are preset in the oxygen concentration sensor in the current vehicle, so that different processing modes are obtained according to different threshold ranges corresponding to different oxygen concentration data, thereby further improving user experience and safety.
Step S30: and if the oxygen concentration data meet the preset threshold range, performing air quality safety control on the parking warm air of the current vehicle.
Further, it is understood that the fresh air passage opening degree and the window opening degree need to be set in advance in a graded manner.
In addition, it should be noted that the opening degree of the fresh air channel may be divided into a first channel level, a second channel level and a third channel level, where the first channel level is the highest opening degree of the fresh air channel, the third channel level is the lowest opening degree of the fresh air channel, the second channel level is the middle of the first channel level and the third channel level, and the first channel level, the second channel level and the third channel level include multiple channel opening degree levels that are sorted from high to low; dividing the opening degree of the car window into a first car window gear, a second car window gear and a third car window gear; the first gear of door window is the door window aperture is the highest, the third gear of door window is the door window aperture is the lowest, door window second gear is in the middle of first gear of door window and door window third gear, just first gear of door window, door window second gear and door window third gear of door window include from high to a plurality of door window aperture grades of low carrying out the sequencing, wherein the grade also sets up in advance by individual, through hierarchical regulation and control to avoid the overstimulation reaction to cause the interference to personnel in the car.
In addition, it should be noted that, if the oxygen concentration data meets a preset first threshold range within a first preset time threshold, it is determined whether the parking heater is turned on, when the parking heater is turned on, it is determined whether the opening of the fresh air channel opens a first channel gear, if the opening of the fresh air channel does not open the first channel gear, the opening of the fresh air channel is turned on by reducing the opening level of the channel at the current channel gear, and then it is determined again whether the oxygen concentration data meets the preset first threshold range within the first preset time; if the opening degree of the fresh air channel opens the first gear of the channel, judging whether the window of the current vehicle opens the first gear of the window, reducing the window opening degree grade of the window at the current window gear to open when the window opening degree of the current vehicle does not open the first gear of the window, and then judging whether the oxygen concentration data in the current vehicle meets the preset first threshold range again.
Further, for ease of understanding, the following is exemplified:
assuming that the first gear of the opening degree of the fresh air channel comprises three grades of ten, nine and eight, and the second gear of the opening degree of the fresh air channel comprises four grades of seven, six, five and four, the third gear of the opening of the fresh air channel comprises three grades, two grades and one grade, the opening of the car window is divided into three grades and ten grades as described above, when the opening of the fresh air channel is opened to nine levels and ten levels are not opened, the opening of the fresh air channel is reduced by one level and changed into eight levels, judging whether the oxygen concentration data still meet a preset first threshold value range within the first preset time, if so, and continuously circulating, if the fresh air channel is opened for ten levels, the vehicle window opening is opened for five levels, judging whether the oxygen concentration data meet a preset first threshold value range within the first preset time, and if so, continuously circulating.
If the oxygen concentration data meet the range of a preset second threshold value, and the oxygen concentration data are equal to a second preset time threshold value, judging whether the opening of the fresh air channel opens a first gear of the channel; when the opening degree of the fresh air channel does not open a first channel gear, increasing the opening degree grade of the fresh air channel at the current channel gear to open, and when the time length corresponding to the oxygen concentration data is equal to a second preset time threshold, returning to the step of judging whether the oxygen concentration data meets a preset second threshold range; when the opening of the fresh air channel opens a first gear of the channel, judging whether the window opening of the current vehicle opens the first gear of the window; and if the window opening degree of the current vehicle does not open the first window gear, increasing the window opening degree of the window at the current window gear to open, and returning to the step of judging whether the oxygen concentration data meets a preset second threshold range or not when the time length corresponding to the oxygen concentration data is equal to a second preset time threshold.
In addition, it should be noted that the preset time threshold is user-defined, and when the operation is performed, the operation can be automatically performed.
Further, for ease of understanding, the following is exemplified:
assuming that the first level of the opening degree of the fresh air channel comprises three levels of ten, nine and eight levels, the second level of the opening degree of the fresh air channel comprises four levels of seven, six, five and four levels, the third level of the opening degree of the fresh air channel comprises three levels of three, two and one levels, the opening degree of the vehicle window is divided into three levels and ten levels as described above, when the opening degree of the fresh air channel is opened to nine levels, the opening degree of the fresh air channel is increased by one level to ten levels, when the opening degree is equal to the first preset time, whether the oxygen concentration data meets a preset second threshold range is judged, if the opening degree is still met, the circulation is continued, when the opening degree of the fresh air channel is opened to ten levels, the opening degree of the vehicle window is adjusted to six levels, when the opening degree is equal to the second preset time, whether the oxygen concentration data meets the preset second threshold range is judged, if so, the loop continues.
It should be understood that if the oxygen concentration data meet a preset third threshold range and the corresponding duration of the oxygen concentration data is equal to a third preset time threshold, the blower and the external circulation are started through a Controller Area Network (CAN) message according to the fresh air controller; inputting fresh air into the current vehicle according to the air blower and the external circulation, and outputting prompt information through a vehicle-mounted voice device until a user opens the door of the current vehicle clear-headed.
In addition, it should be noted that when the oxygen concentration data meet a preset third threshold range, the fresh air controller is automatically started, the vehicle-mounted air conditioner of the current vehicle is controlled through the CAN message, so that fresh air is transmitted into the vehicle, an in-vehicle voice prompt is started, a user is alerted, if the user is not alerted and the air quality in the vehicle is not improved, the danger alarm lamp and the vehicle door are automatically turned on through the CAN message, and the outside is attracted to call the mobile phone of the vehicle owner and other measures to save the personnel in the vehicle; if after 10min, the oxygen concentration in the vehicle is still not improved, the vehicle networking platform is used for calling for rescue, and the vehicle position is sent to the rescue platform.
In addition, if the oxygen concentration data meet the range of a preset fourth threshold value and equal to a fourth preset time threshold value, starting a blower and external circulation through a CAN message according to a fresh air controller;
inputting fresh air into the current vehicle according to the blower and the external circulation, outputting prompt information through vehicle-mounted voice equipment, and outputting early warning prompt information through a CAN message according to a vehicle body controller; when the oxygen concentration data is equal to a fifth preset time threshold, judging whether the oxygen concentration data meets the preset fourth threshold range, and when the oxygen concentration data meets the preset fourth threshold range, transmitting the information of the current vehicle to a vehicle networking controller through a CAN message; and sending the information of the current vehicle to a road rescue platform according to the vehicle networking controller.
In the embodiment, when a current vehicle is detected, the speed of the current vehicle is acquired, when the speed is zero, the current vehicle is determined to be in a static state, then sleeper weight data acquired by a sleeper sensor at a preset position on the current vehicle and/or seat weight data acquired by a seat weight sensor are acquired, then whether a person is in the current vehicle is judged according to the sleeper weight data and the seat weight data, when a person is in the current vehicle, oxygen concentration data acquired by an oxygen concentration sensor in the current vehicle is acquired, and different air quality safety controls are performed on parking warm air of the current vehicle according to different preset threshold ranges corresponding to the oxygen concentration data, wherein under the condition of good air quality, control of interfering persons is avoided, when the air quality is reduced, according to different air quality, through different ventilation solution to reach better user experience and security.
Referring to fig. 3, fig. 3 is a schematic flow chart of a second embodiment of a method for controlling air quality safety in a vehicle according to the present invention.
