Detailed Description

The following description of preferred embodiments will provide further details of the present invention.

This application main automobile is at low-speed, idle speed, when backing a car, and the peculiar smell of surrounding environment gets into passenger cabin, reduces the travelling comfort, and in order to solve this kind of problem, the automobile exhaust of this application main analysis surrounding environment, peculiar smell get into the main way in cockpit are in other circulation modes except the inner loop when vehicle air conditioner opens, cause the interior air of car not good, influence healthy, influence user experience.

In order to solve the above problems, the following solutions are adopted to solve the above problems, specifically:

a control method for preventing automobile exhaust from entering an automobile comprises the following steps: and entering a monitoring step after the triggering condition is met, starting monitoring the vehicle speed after entering the monitoring step, and adjusting the air conditioning state of the vehicle to avoid tail gas from entering the vehicle through an air conditioning air inlet when the vehicle speed is less than a set vehicle speed threshold value V and the duration time is more than a first set time threshold value.

The method comprises the following steps of starting an automobile, starting an air conditioner, and monitoring when the automobile is started and the air conditioner is started. And after the monitoring step is carried out, when the vehicle speed is less than a set vehicle speed threshold value V and the duration time is greater than a first set time threshold value, controlling the air conditioning mode of the vehicle, and adjusting the air conditioning mode to be an internal circulation mode.

And adjusting the air conditioning mode to an internal circulation mode, simultaneously recording the air conditioning mode before adjustment, monitoring vehicle speed change after the adjustment to the internal circulation, and controlling the air conditioning mode to return to the air conditioning mode before adjustment when the vehicle speed is greater than a set vehicle speed threshold value V and the duration time reaches a second set time threshold value.

The vehicle speed threshold V is set to be calibrated in advance, and meets the requirements of the vehicle speed under the conditions of idle speed, low speed, reverse and other slow speeds, for example, the vehicle speed threshold V is 10 KM/h. After the air conditioner operation mode is adjusted to the internal circulation mode, the adjustment reminding of the air conditioner mode is given through an indicator lamp, a display screen and/or an instrument of the vehicle.

In the application, hardware is not required to be used for realizing the method, the method adopts the hardware on the vehicle in the prior art, the method is integrated in a calculation and program mode in a controller on the vehicle, such as BCM and VCU, taking the VCU as an example, the VCU constantly monitors the vehicle running state, the air conditioner starting state and the vehicle speed state, when the vehicle is in a starting state and the air conditioner is turned on and the vehicle speed is less than a set vehicle speed threshold value, the VCU firstly records parameters such as an operation control mode of the air conditioner and the like, then the running mode of the air conditioner is changed into an internal circulation working mode, the vehicle speed signal is monitored in real time, when the vehicle speed is greater than the set vehicle speed and the duration reaches the set time, the VCU controls the air conditioner to work in the previous state, that is, the VCU controls the air conditioner to work according to the recorded parameters such as the running mode of the air conditioner and the like stored in the memory, so that the work feeds back the original working mode.

The air conditioner is automatically controlled to only work in an inner circulation mode under the conditions of low speed, idling, backing and the like through the algorithm, so that the defect of poor air quality in the vehicle caused by the fact that gas around the vehicle enters the vehicle, such as tail gas and the like, is avoided. The purpose of controlling the air conditioner to be in the internal circulation is to prevent the air conditioner outside the automobile from entering the automobile through an air duct of the air conditioner air door, which is also the main way for outside air to enter the automobile.

The embodiment that this application set up speed of a motor vehicle V, settling time all can adjust according to the reality, through experimental verification and analysis, this application provides a more reliable speed of a motor vehicle threshold value, duration to drinking includes: during the driving of automobiles, the driving frequency is high on urban roads, and the conditions of waiting for traffic lights, traffic jam, backing up and warehousing are usually encountered. Under the condition that the automatic air conditioner is started, when the vehicle speed is detected to be less than 10km/h within 5S, the air conditioner is automatically switched to an internal circulation mode, and when the vehicle speed is detected to be greater than 10km/h within 15S, the internal and external circulation air door returns to the early working mode. Therefore, the automobile tail gas can be prevented from entering the passenger cabin when the automobile runs at a low speed and is idled and backs a car, so that the comfort of the human body is reduced, and the health is damaged. The invention can solve the problem that the tail gas of the automobile enters the passenger cabin when the automobile is driven at low speed and idling, thereby reducing the comfort of the human body and being harmful to the health.

It is clear that the specific implementation of the invention is not restricted to the above-described embodiments, but that various insubstantial modifications of the inventive process concept and technical solutions are within the scope of protection of the invention.
