Method, device and vehicle for detecting particulate matter

Abstract

The present disclosure relates to a method, device and vehicle for detecting particulate matter. The method obtains vehicle status information; and determines a target detection mode from preset detection modes according to the vehicle status information, and the target detection mode includes an infrared detection mode and / or A laser detection method; through the target detection method, target particles inside the vehicle are detected to obtain first particle parameters. In this way, by determining the target detection method from the preset detection methods according to the vehicle state information, the service life of the detection device can be extended while improving the accuracy of the detection result.

Description

technical field [0001] The present disclosure relates to the technical field of vehicles, in particular, to a method, device and vehicle for detecting particulate matter. Background technique [0002] In recent years, urban environmental pollution has become more and more serious, and smog has appeared frequently. The content of PM2.5 (Particulate Matter, particulate matter) in the air has gradually attracted people's attention, so the content of PM2.5 in the air in the car has become a hot spot for people to pay attention to. one of the objects. At present, the PM2.5 detection devices suitable for in-car configuration are generally infrared detection methods or laser detection methods, and infrared detection methods usually have large deviations in detection results and low accuracy, and cannot obtain accurate detection results; laser detection methods are due to The life of the laser diode is short (generally about 10,000 hours in normal use), and the sensor needs to be r...

AI Technical Summary

Problems solved by technology

At present, the PM2.5 detection devices suitable for in-car configuration are generally infrared detection methods or laser detection methods, and infrared detection methods usually have large deviations in detection results and low accuracy, and cannot obtain accurate detection results; laser detection methods are due to The life of the laser diode is short (generally about 10,000 hours in normal use), and the sensor needs to be replaced every 1-2 years if it is kept on during normal use, and in a high temperature environment, it will Causes additional loss of laser diodes. Therefore, considering various environments, when using laser detection methods to detect PM2.5, the PM2.5 detection equipment needs to be replaced every less than a year.
