Title:
DETECTION METHOD FOR VEHICLE ENTERING INDOOR ENVIRONMENT, ELECTRONIC DEVICE, AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2023/098365
Kind Code:
A1
Abstract:
A detection method for a vehicle entering an indoor environment, an electronic device, and a storage medium. An electronic device is placed in a vehicle. The electronic device comprises an accelerometer, a magnetometer, and a communication card. The electronic device performs ramp detection and barrier gate entrance detection by using the accelerometer to obtain a first detection result and a second detection result, respectively; performs geomagnetic signal detection by using the magnetometer to obtain a third detection result; and performs cellular signal detection by using the communication card to obtain a fourth detection result. The detection method for a vehicle entering an indoor environment comprises: obtaining a plurality of detection results according to a detection cycle, and determining whether the vehicle enters the indoor environment according to at least two of the detection results. By separately detecting by means of the accelerometer, the magnetometer, and the communication card and performing comprehensive determining on the basis of at least two detection results, the accuracy of identifying whether the vehicle enters the indoor environment is improved.
