Problems solved by technology

Although the method for preventing suffocation in a car provided by this invention can ensure that people or pets will not suffocate when they stay or stay in a closed car, this invention cannot intelligently adjust the air volume of the air conditioner according to the situation in the car, and the comfort is not high. When the vehicle is in the driving state, the air concentration in the car cannot be intelligently adjusted, and the driving environment is not comfortable.

Embodiment 1

[0024] The air circulation control method in the vehicle includes: starting the vehicle static circulation mode or the high-speed driving circulation mode; when starting the vehicle static circulation mode, detecting the oxygen concentration and carbon dioxide concentration in the vehicle in real time within the first preset time value, the first The preset time value can be set to 20-35 minutes. When the oxygen concentration and carbon dioxide concentration change within the first preset time value, the automobile air conditioner is controlled to enter the external circulation mode and the air conditioner blower 4 is started. concentration value to adjust the air volume of the blower 4 so that the oxygen concentration and carbon dioxide concentration in the car are maintained at the concentration target value; The target temperature is to control the automobile air conditioner to switch between the internal circulation mode and the external circulation mode. When the oxygen co...

Embodiment 2

[0037] The content of this embodiment is basically the same as that of Embodiment 1. The difference is that in the method for controlling the air circulation in the vehicle, it is judged whether to start the vehicle static circulation mode or the high-speed driving circulation mode according to the engine running state. In the state, the static circulation mode of the vehicle is automatically started after the second preset time value, wherein the second preset time value can be set to 4-6 minutes; the high-speed traffic circulation mode is automatically started when the engine running state is turned on. Judging whether to start the vehicle static circulation mode or high-speed traffic circulation mode based on the engine running status can avoid personal safety problems caused by forgetting to turn on the vehicle static circulation mode or high-speed traffic circulation mode, and effectively guarantee the safety and comfort of the occupants in the vehicle sex.

Embodiment 3

[0040] The content of this embodiment is basically the same as that of Embodiment 1. The difference is that in the method for controlling the air circulation in the vehicle, the control method also includes starting the static circulation mode or the high-speed driving circulation mode of the vehicle through the air-conditioning operation panel and according to the operating state of the engine. To determine whether to start the static circulation mode of the vehicle or the high-speed driving circulation mode, the static circulation mode of the vehicle is automatically activated after the second preset time value when the engine running state is off, wherein the second preset time value can be set to 4 -6 minutes; when the engine running state is on, the high-speed driving circulation mode is automatically activated. The use of the air-conditioning operation panel facilitates the operation of the driver, the design is humanized, and the driving comfort can be improved. Judging...

Abstract

The invention provides a vehicle interior ventilation control method and device and belongs to the technical field of vehicles. By means of the vehicle interior ventilation control method and device, the problem that in the prior art, the degree of comfort of the driving environment is not high is solved. The vehicle interior ventilation control method comprises the steps that when a vehicle static ventilation mode is started, a vehicle air conditioner is controlled to enter the external cycle work mode and an air blower of the air conditioner is started when the oxygen concentration and the concentration of carbon dioxide are changed in the first preset time value; and when a high-speed driving ventilation mode is started, according to the detected oxygen concentration, the concentration of carbon dioxide, environment temperatures inside and outside a vehicle as well as the set target temperature, a temperature motor is controlled to work on the promise of ensuring that the oxygen concentration and the concentration of carbon dioxide are maintained at the target concentration values, so that the temperature in the vehicle is maintained at the target temperature. The vehicle interior ventilation control device is used for implementing the vehicle interior ventilation control method. According to the control method and device, the comfort and safety of the environment in the vehicle can be effectively improved when the vehicle is in a running or stop state.

Description

technical field [0001] The invention belongs to the technical field of automobiles, and relates to a method and a device for controlling air circulation in a vehicle. Background technique [0002] In existing cars, air conditioners are basically equipped to meet the needs of drivers and passengers in different seasons; and because of the increasingly complex social environment, the design of cars is becoming more and more closed. In addition to turning on the air conditioner or opening the windows during driving, the car can circulate the air in the car. When the windows and the air conditioner are closed, the air in the car cannot be circulated and circulated well. In the season when the weather is relatively stuffy, the lack of air circulation in the car is one of the main reasons for the temperature rise in the car. The rise of the temperature inside the car will reduce the comfort of the car. Moreover, with the progress of society and the improvement of people's livin...
