System for exhausting air in passenger compartment during vehicle door closing

Abstract

The invention discloses a system for exhausting air in a passenger compartment during vehicle door closing. The system comprises a vehicle door position sensor, vehicle door glass, a glass lifter anda vehicle body controller. The glass lifter is used for driving the vehicle door glass to do lifting motion, and sending a vehicle door glass position signal to the vehicle body controller, the vehicle door position sensor is used for sensing the opening and closing condition of a vehicle door and sending vehicle door opening or closing signals to the vehicle body controller, and when receiving the vehicle door opening signal, the vehicle body controller calculates the position where the vehicle door glass is located at present according to the vehicle door glass position signal, and controlsthe vehicle door glass to descend to a set height or keep the vehicle door glass fixed at the current position according to the difference value between the position where the vehicle door glass is located at present and a set position of the vehicle door glass. The vehicle window glass is controlled to descend when the vehicle door is opened, air in a vehicle compartment can be exhausted out of avehicle through the opened vehicle window glass after the vehicle door is closed, door closing air resistance can be greatly reduced, and door closing is easy and convenient.

Description

technical field [0001] The invention relates to an automobile exhaust system, in particular to an exhaust system for a passenger compartment with a door closed. Background technique [0002] At present, vehicles are equipped with pressure release valves (also called exhausters) to release the pressure in the cabin and increase the comfort of the vehicle, especially during the process of vehicle closing and air conditioning external circulation, etc., if the valve cannot be released in time The pressure in the cabin will cause problems such as the need to close the door with greater force and / or the pressure in the vehicle will be higher, causing discomfort to the passengers in the vehicle. [0003] At present, the door-closing exhaust of the passenger compartment of an automobile is usually realized through the exhaust valve of the trunk. Since the exhaust valve of the trunk is opened by air pressure, the response speed is slow and the exhaust effect is poor. Moreover, the ...

Problems solved by technology

[0002] At present, vehicles are equipped with pressure release valves (also known as exhausters) to release the pressure in the cabin and increase the comfort of the vehicle, especially during the process of vehicle closing and air conditioning external circulation, etc., if the valve cannot be released in time The pressure in the cabin will cause the need to close the door with greater force and / or the pressure in the vehicle will be higher, causing discomfort to the passengers in the vehicle, etc.

[0003] At present, the closed door exhaust of the passenger compartment of the car is usually realized through the trunk exhaust valve. Since the current trunk exhaust valve is opened by air pressure, the response speed is slow and the exhaust effect is poor.

Moreover, the current luggage compartment exhaust valve is easily affected by environmental factors such as driving conditions and wind, and will open during driving, affecting NVH performance, and there is a risk of dust entering the luggage compartment
