The following provides a detailed description of the driver state detection method, device, electronic device and storage medium provided by the embodiments of the present application.
Referring to fig. 1, fig. 1 is a schematic flowchart illustrating a method for detecting a driver state according to an embodiment of the present disclosure. The flow shown in fig. 1 will be described in detail below. The above-described driver state detection method may specifically include the steps of:
step S110: pressure data when a whistling device of a vehicle is pressurized is acquired, and the pressure data includes at least one of pressure magnitude, pressure change rate, pressure duration, pressure times, pressure frequency, and pressure area.
In order to identify and guide the whistling operation of the driver, a pressure detection device may be additionally installed on a horn button of the vehicle, wherein the pressure detection device may be implemented by a pressure sensor or a pressure detection circuit, and is not limited herein. Further, taking a pressure sensor as an example, a pressure detection device is additionally arranged on a horn key of the vehicle, or a pressure sensor is additionally arranged in the center of the horn key; alternatively, a plurality of pressure sensors may be installed under the horn so that the driver can detect pressure data regardless of the posture of pressing the horn.
In some embodiments, when the whistle device of the vehicle is pressed, that is, the horn button described above is pressed, pressure data at the time of pressing may be acquired, which is detected by the pressure detection device. The whistle device can be the loudspeaker of vehicle, and the whistle device of vehicle is compressed, can be that the driver presses the whistle device, and when the driver pressed loudspeaker promptly for the whistle device of vehicle is compressed.
In some embodiments, the pressure data may include at least one of a pressure magnitude, a pressure change rate, a pressure duration, a pressure number, a pressure frequency, and a pressure area. For example, the acquired pressure data may include pressure magnitude, pressure times, pressure frequency, or each of the pressure magnitude, the pressure change rate, the pressure duration, the pressure times, the pressure frequency, and the pressure area, and the specific content included in the pressure data is not limited herein. Wherein, pressure size can indicate the driver and press the size of the dynamics of whistling device, pressure rate of change can indicate the speed that the driver dynamics changes when pressing the whistling device, duration that the pressurized can indicate the driver and press the duration of whistling device, the pressurized number of times can indicate the number of times that the driver pressed the whistling device, pressurized frequency can indicate the frequency that the driver pressed the whistling device, pressurized area can indicate the driver when pressing the whistling device, the area of contact of hand and whistling device.
Step S120: status information of a driver of the vehicle is obtained based on the pressure data.
During driving, the whistling operation of the driver may be affected by the state of the driver, for example, when the road is crowded, the driver may continuously press the horn of the vehicle due to the urgency. Therefore, the state information of the driver of the vehicle can be obtained based on the acquired pressure data, so that the driver is prompted according to the state information of the driver, operation guidance is provided for the driver, and potential safety hazards are reduced.
In some embodiments, the state information of the driver corresponding to the acquired pressure data may be obtained according to a mapping relationship between the pressure data and the state information, which is established in advance. For example, if the pressure data is acquired such that the pressure application time period is ten seconds, that is, the driver presses the horn all the time within ten seconds, the state information of the driver corresponding to the pressure application time period being ten seconds may be obtained as anger according to the mapping relationship established in advance. For another example, the obtained pressure data is that the number of times of compression is ten, and the compression frequency is 2 times/second, that is, the driver presses the horn ten times within 5 seconds, and the state information of the driver corresponding to the number of times of compression and the compression frequency is impatient can be obtained according to the mapping relationship established in advance.

In some embodiments, the prompt may be the status information itself, i.e., the status information of the driver is output. The prompt information can also be other prompt information, namely other prompt information is output according to the state information, for example, when the driver presses the loudspeaker ceaselessly, corresponding pressure data is obtained, if the pressed times are larger than the preset times, the state information of the driver can be obtained to be impatient, and the driver can be prompted not to press the loudspeaker. Further, other auxiliary information may be combined to output a corresponding prompt, for example, in the above example, the road condition information may be acquired, and when the current road condition information represents a congestion state and the driver presses the horn continuously, the prompt information may be output to prompt the driver to wait for patience. For another example, when the driver presses the horn, the driver may obtain the speed data of the vehicle, and if the vehicle speed is fast and the driver continuously presses the horn, the driver may be prompted to reduce the vehicle speed and stop pressing the horn.
In some embodiments, after obtaining the status information of the driver, the prompt information may be output when the status information satisfies the early warning status information. The warning status information may be preset by the system, and is not limited herein. As a specific embodiment, when the state information of the driver obtained from the pressure data is a fatigue state, when the degree of the fatigue state of the driver satisfies a preset fatigue state degree, a prompt message may be output to prompt the driver to stop driving the vehicle.
