On September 19, information from the Tianyancha App revealed that Xiaomi Auto Technology Co., Ltd. has made public its recently - filed patent for a "fatigue alert method, device, vehicle, medium, and program product".

This patent pertains to intelligent cockpit technology. It operates by analyzing the voice signals of the driver (the target subject) to ascertain their fatigue level. When signs of fatigue driving are detected, it promptly issues alerts.

Unlike traditional methods, this approach does not depend on cameras to capture images. This design serves a dual purpose. Firstly, it safeguards the driver's privacy. Secondly, it eliminates the issue of reduced detection accuracy that can occur when the driver is wearing sunglasses or when there are other obstructions.

By being able to monitor the driver's fatigue status in real - time and with high precision, this technology significantly bolsters driving safety.
