Example Embodiment

[0025] Embodiments of the present invention provide a steering wheel-based driver monitoring method, steering wheel and electronic equipment.
[0026] In order to enable those skilled in the art to better understand the technical solutions in the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described The embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
[0027] like figure 1 As shown, the embodiment of the present invention provides a steering wheel-based driver monitoring method, and the method may specifically include the following steps:
[0028] Step S01 , detecting the driver's physical sign information through the sensor arranged on the steering wheel.
[0029] A sensor that can detect human body sign information is installed on the steering wheel, so that when the driver puts his hands on the steering wheel, the driver's sign information can be detected.
[0030] Further, corresponding sensors can be set for the physical sign information according to actual needs, and the embodiment of the present invention only uses heart rate, body temperature and blood pressure as examples for illustration.
[0031] The sensor sends the detected driver's physical sign information to the control unit ECU arranged on the steering wheel, and the control unit may be arranged on the steering wheel frame.
[0032] figure 2 The schematic diagram of the surface of the steering wheel rim provided by the embodiment of the present invention, such as figure 2 As shown, the steering wheel specifically includes a steering wheel skeleton, a steering wheel foam layer, a sensor and a steering wheel skin from inside to outside.
[0033] Step S02, determining the physical state of the driver according to the physical sign information.
[0034] image 3 A schematic diagram of the connection relationship of the control unit of the steering wheel provided by the embodiment of the present invention, as shown in image 3 As shown, the control unit is respectively connected to the power supply of the vehicle through terminal A, and is connected to the integrated terminal of the steering wheel skin and the sensor through terminal B. The control unit can be set in the frame of the steering wheel or integrated into the whole vehicle. In the vehicle control unit, no specific limitation is made here. The control unit analyzes and processes the received sign information, monitors changes in heart rate, body temperature and blood pressure, and analyzes the driver's physical state. The physical state may include the driver's physical health state and mood.
[0035] Step S03, emitting light corresponding to the body state through the light source integrated in the steering wheel skin.
[0036] The control unit converts the analyzed body state into a corresponding luminous signal and sends it to the light source integrated in the steering wheel skin. The light source generates light according to the received luminous signal, so that the driver can know his own physical state in time, so as to make a corresponding response.
[0037] For example, when the driver's physical condition is normal, the steering wheel skin can be instructed to emit normal white light, and when the driver is analyzed to be in a fatigue state, the steering wheel skin can be instructed to send a bright or red warning light to remind the driver of a dangerous situation. To achieve the purpose of safe driving.
[0038] Further, there are many ways to integrate light sources on the steering wheel skin. In the embodiment of the present invention, light sources of three primary colors are evenly distributed inside the steering wheel skin. The skin of the steering wheel with dispersed light sources can receive light signals from the control unit to emit lights of different colors and intensities.
[0039] Figure 4 The schematic cross-sectional view of the steering wheel skin provided by the embodiment of the present invention, such as Figure 4 As shown, light sources of three primary colors are evenly distributed inside the man-made fibers of the leather-based surface of the steering wheel skin. This light source can receive the luminous information sent by the control unit to adjust the color and intensity of the light emitted by the steering wheel skin.

Through the embodiments of the present invention, it is possible to accurately control the lights displayed on the steering wheel according to the driver's physical state.
[0041] Further, such as Figure 5 As shown, after the above step S02, the method further includes:
[0042] Step S04, if the physical state satisfies the preset warning condition, send out warning information.
[0043] The control unit can also be connected with the large screen of the vehicle or the ambient light of the vehicle. When it is determined through analysis that the physical state satisfies a preset warning condition, corresponding warning information is sent to the ambient light and/or the large screen.
[0044] When it is determined that the physical state is in a tense state, by sending corresponding warning information to the ambient light, instructing the ambient light to cooperate with the steering wheel skin to emit light of a soothing color, so as to achieve the effect of soothing the driver's emotions.
[0045] When it is determined that the driver's physical condition is in an unhealthy state, for example, the body temperature is too high, in addition to instructing the steering wheel skin to emit a light of the color used to represent the warning, an early warning message can also be sent to the large screen of the vehicle to remind the driver Seek medical treatment as soon as possible, and can combine the car-machine system to navigate to the nearest hospital on the big screen, so as to achieve the purpose of human-vehicle interaction.
