Abstract

The invention discloses a method, a device and a system of detecting the driving status of a driver. The method comprises the steps of playing a preset voice segment; acquiring a read-after voice segment after the driver reads the preset voice segment; determining the driving status of the driver according to at least one characteristic value of the read-after voice segment, wherein the driving status of the driver includes a normal driving status and an abnormal driving status; and generating a control instruction according to the driving status of the driver. By adopting the method, the device and the system of detecting the driving status of the driver, the problems that in the prior art the arrangement space in a car is increased, devices are easily damaged and the identification result is inaccurate due to the fact that a plurality of externally arranged hardware devices are adopted to identify that the driver is under abnormal driving status are solved.

Description

technical field [0001] The invention relates to the field of vehicle control, in particular to a method, device and system for detecting the driving state of a driver. Background technique [0002] Drivers drive for a long time, often causing dozing off or even falling asleep, which greatly increases the hazards of driving, not only endangering the driver's own life safety, but also endangering the life safety of other drivers. Drunk driving is equally harmful. The driver's ability to drive a car under the condition of drinking alcohol is greatly reduced, and the ability to handle emergency situations is also reduced, often causing crashes and endangering personal safety. Existing anti-fatigue driving and anti-drunk driving equipment for automobiles can be applied in the following ways. For example, to prevent drunk driving is to detect alcohol concentration based on alcohol concentration detectors to identify whether the driver is drinking, and to prevent fatigue driving is...
