A method for detecting people in a vehicle

Abstract

The invention discloses a method for detecting people in a vehicle, which comprises the following steps: receiving vehicle body communication bus message information, and analyzing the information to obtain the vehicle action state; using a millimeter wave radar sensor to collect data in the vehicle; corresponding to different vehicle actions The state uses the in-vehicle data collected by the millimeter-wave radar sensor to calculate the confidence level; classify the confidence level and determine the threshold value of each level; determine the detection confidence level of different vehicle action states according to the corresponding threshold value, and according to the confidence level Determine the condition of the occupants of the vehicle. The millimeter-wave radar technology provided by the present invention, combined with the vehicle's detection of multiple cycles at different stages, improves the high reliability of the detection of the remaining occupants in the vehicle, and uses the innovative calculation method of confidence, which greatly reduces the number of missed reports, The probability of false alarms, and can accurately detect and judge the location of the left occupant in the car. And through SMS, telephone, vehicle sound and light alarm and other ways to remind.

Description

technical field [0001] The invention is applied to the field of detection of vital signs in vehicles, in particular to a method for detection of persons in vehicles. Background technique [0002] With the continuous improvement of social economy and technology, cars have become the most common means of transportation for people to travel. However, in daily life, life safety accidents caused by living creatures such as infants and pets are left in the car. Increase. The common solutions currently on the market are: [0003] (1) Use infrared sensors to detect, the solution will be seriously affected by temperature and limited by the surrounding environment of the vehicle; [0004] (2) There are mature technologies for using artificial intelligence camera detection to achieve camera detection targets, but this solution involves the privacy of individual occupants in the car, and the detection scene in the car is not suitable for promotion; [0005] Therefore, it is an urgent...
