In-vehicle air quality monitoring and automatic ventilation control system

Abstract

The invention provides an in-vehicle air quality monitoring and automatic ventilation control system which comprises an in-vehicle air quality detector, an external air quality detector, a central control unit and an execution module. A ventilation program receives detection result information from an in-vehicle sensor and an external sensor and compares the detection result information with a preset target value; if in-vehicle air quality satisfies the set target value, ventilation is not performed; if the in-vehicle air quality dissatisfies the set target value, the air quality in a vehicleis compared with that outside the vehicle; if the air quality in the vehicle is better than that outside the vehicle, the ventilation is not performed; and if the air quality in the vehicle is worse than that outside the vehicle, an instruction is given to the execution module to perform the ventilation. The system employs comprehensive consideration for realization of a ventilation function; a single system or a combination of multiple systems can achieve selection of a temperature, an air speed and a window opening position and control of vehicle window opening, sunroof opening and an angle.

Description

technical field [0001] The invention relates to the field of automobile engineering design and specifically relates to an air quality monitoring and automatic ventilation control system in a vehicle. Background technique [0002] With the development of the automobile industry and the continuous improvement of automobile technology, consumers have higher and higher requirements for the performance of automobiles in all aspects. The quality of the air directly affects the mood of the drivers and passengers; the existing ventilation methods in the car are mainly realized by the air conditioner, the sunroof, and the manual operation of the doors and windows. Differences, everyone's tolerance is different, and the perception and tolerance of the air quality in the car are also different. The existing implementation technology requires the driver to perform manual operations, which will distract the driver's energy and affect driving safety. [0003] The existing method of reali...

[0002] With the development of the automobile industry and the continuous improvement of automobile technology, consumers have higher and higher requirements for the performance of automobiles in all aspects. The quality of the air directly affects the mood of the drivers and passengers; the existing ventilation methods in the car are mainly realized by the air conditioner, the sunroof, and the manual operation of the doors and windows. Differences, the tolerance of each person is different, and the perception and tolerance of the air quality in the car are also different. The existing implementation technology requires the driver to perform manual operations, which will distract the driver's energy and affect driving safety.

[0003] The existing method of realizing ventilation in the car is through manual operation of air conditioners, doors, windows, and sunroofs, and the process of ventilation is determined by human subjective factors due to the differences in the individual perception and tolerance of the occupants in the car Function, when the driver's eyes are out of the driving route, his hands off the steering wheel and his body deviates from the correct driving posture, it will have a certain impact on the driving of the vehicle and directly affect the safety of driving.
