Method and device for controlling air circulation in vehicle

Abstract

The embodiment of the invention provides a method and device for controlling air circulation in a vehicle, and the method comprises the steps: detecting air quality parameters in the vehicle, determining air quality data according to the air quality parameters, and judging whether the air quality in the vehicle is qualified or not according to the air quality data; when the air quality in the vehicle is qualified, obtaining video data, shot by a camera device, of a user in the vehicle in a preset time period, and intercepting a facial expression and a gesture action of the user in the video data; performing micro-expression analysis on the facial expression, and obtaining a carsickness index corresponding to the user according to a micro-expression analysis result; detecting whether the gesture action is a preset carsickness action or not; when the carsickness index is larger than a preset threshold value and the gesture action is a preset carsickness action, sending a starting instruction to a circulation filtering device corresponding to the vehicle. By adopting the method, whether the user is carsickness can be detected, and when the user is carsickness, ventilation filtering between the vehicle and the outside is completed in time, so that the carsickness of the user is relieved.

Description

technical field [0001] The invention relates to the technical field of automobile interior adjustment, in particular to a method and device for controlling air circulation in a car. Background technique [0002] When the vehicle is driving with the windows closed, the interior of the vehicle is a closed space, and the air quality inside the vehicle is constantly declining due to the closed space. For the driver and passengers in the vehicle, the air quality in the vehicle will affect the driving comfort. An important indicator, if the air quality in the car is not high, it will cause the passengers in the car to experience symptoms of motion sickness. In this case, it is usually necessary to open the window to exchange air with the outside world. [0003] However, when motion sickness occurs, the external environment may not support opening the car window to complete air exchange, such as heavy rain or extremely low outside temperature. In this case, it often needs to rely o...

Problems solved by technology

[0003] However, when motion sickness occurs, the external environment may not support opening the car window to complete air exchange, such as heavy rain or extremely low outside temperature. In this case, it often needs to rely on the vehicle's circulation system to complete air exchange with the outside world, but For passengers, it is usually impossible to autonomously operate the vehicle to complete the air exchange with the outside world when symptoms of motion sickness occur, which will aggravate the motion sickness of passengers and affect the travel experience of passengers
