Abstract

The present invention discloses a vehicle steering wheel, relating to the field of auto part technologies, and solving the problems of being prone to occurrent of traffic accidents and reducing traffic safety when the driver is driving in a fatigue state. In embodiments of the present disclosure, the vehicle steering wheel comprises a wheel rim, at least one oximeter is provided within handheld areas of the wheel rim and connected to a control device connected to an alarm device; and the control device is configured to judge whether or not a driver is in a fatigue driving state according to an oxyhemoglobin saturation value in the body of the driver detected by the oximeter, and to control the alarm device to operate if judging the driver is in the fatigue driving state. The present invention is mainly applied in vehicles.

First claim

1 . A vehicle steering wheel comprising:
a wheel rim, wherein at least one oximeter is provided within handheld areas of the wheel rim and connected to a control device connected to an alarm device; and wherein the control device is configured to judge whether or not a driver is in a fatigue driving state according to an oxyhemoglobin saturation value in a body of the driver detected by the oximeter, and to control the alarm device to operate if judging the driver is in the fatigue driving state.

2 . The vehicle steering wheel according to claim 1 , wherein a recess is provided in a rear surface of the wheel rim at a position corresponding to a center area of a side end of the wheel rim;
and the oximeter is located within the recess, and sealed and fixed in the recess by a cover plate.

3 . The vehicle steering wheel according to claim 2 , wherein the recess comprises two recesses which are symmetrically provided in two side ends of the wheel rim; each of the recesses is an arched recess having two higher side portions and a lower middle portion in a circumference direction of the wheel rim.

4 . The vehicle steering wheel according to claim 3 , wherein the cover plate has a configuration conforming to that of the arched recess and is a transparent plastic plate; and the cover plate is adhered and fixedly connected to the wheel rim.

5 . The vehicle steering wheel according to claim 3 or 4 , wherein four oximeters are provided in each of the recesses and arranged equidistantly in the circumference direction of the wheel rim.

6 . The vehicle steering wheel according to claim 5 , wherein a probe of each of the oximeters comprises a dual-wavelength light emitting diode and a photodiode; wherein the dual-wavelength light emitting diode is configured to emit light, and the photodiode is configured to receive reflected light after the emitted light is irradiated onto the body.

7 . The vehicle steering wheel according to claim 1 , wherein the alarm device comprises a display device connected to the control device; and the display device is an indicator or a cue icon.

8 . The vehicle steering wheel according to claim 7 , wherein the alarm device further comprises:
an audio alarm device, the audio alarm device being connected to the control device.

9 . The vehicle steering wheel according to claim 8 , wherein the control device is an Electronic Control Unit of a vehicle, and the Electronic Control Unit is provided with a pre-alarming oxyhemoglobin saturation threshold therein.

10 . The vehicle steering wheel according to claim 4 , wherein four oximeters are provided in each of the recesses and arranged equidistantly in the circumference direction of the wheel rim.

11 . The vehicle steering wheel according to claim 6 , wherein the probe of each of the oximeters comprises one dual-wavelength light emitting diode and one photodiode.
