2) surpass (shaking to the left and right and the angle that upwards comes back) when setting critical value when the variation of driver's head inclination angle, neitherly have any caution start.
3) stop action (when reaching 10 seconds) when head, sensor can be detected driver's head reaction:
If driver's head stops action (critical value of setting) when reaching 10 seconds, do caution for the first time.With immediately with normal audio (containing electric current and vibrating device) warning drivers (imitating) as 3 sound.
Reach 15-25 during second when driver's head stops action, start caution for the second time.Audio (containing than heavy current and vibration) warning drivers more rapidly immediately starts simultaneously and connects the automobile safety seat belt vibrating device, and warning drivers (or start the massage shaking device that is located at the electric automobile seat simultaneously, contain current device).And start sound equipment (the sound size that is enough to driver in the watchful drowsiness) in the car automatically.
When driver's head stops action when reaching more than 25 seconds, except that starting above device, open automatically simultaneously vehicle window (allow the car exogenous wind cut and noisy sound into the car, with strong warning drivers).
In addition, gravity inclination perceptron of the present utility model can have following function:
Can do 6 direction of principal axis sensings, move or motionlessly all can respond to.
Except that detecing the side headwork, the sensing apparatus that is located at the steering wheel rotating base also can start warning function simultaneously.
But the c. action of this device Auto-Sensing steering wheel (action of driver's hand just) is done caution for the first time immediately when making driver's hand not stop action when reaching 10 seconds (steering wheel does not rotate); With normal audio (containing current device) warning drivers (imitating) as 3 sound.
The action that stops steering wheel as the driver reaches 15-25 during second, starts caution for the second time.Audio (containing than heavy current) warning drivers more rapidly immediately starts simultaneously and connects the automobile safety seat belt vibrating device, and warning drivers (or start the massage shaking device that is located at the electric automobile seat simultaneously, contain current device).And start sound equipment (the sound size that is enough to driver in the watchful drowsiness) in the car automatically.
When the driver stops steering wheel action and reaches more than 25 seconds, except that starting above device, open automatically simultaneously vehicle window (allow the car exogenous wind cut and noisy sound into the car, with strong warning drivers).
Its warning way can cooperate car body:
1) is located at vibrations and electric current on the car belt
2) be located at vibrations and electric current under the driver seat
3) be located at vibrations and electric current on the vehicle steering
4) be located at vibrations and electric current on the bluetooth earphone
In addition:
1) can stimulate user's acupoint and nerve that caution (provide two kinds of different electric currents selective) is provided with the discharge mode of great-jump-forward.
2) do caution to rock vibration mode.
3) do caution with sound and light signal.
4) open the big audio of sound equipment automatically and do caution).
5) open automatically that vehicle window is cut by the car exogenous wind and noisy sound into the car, strong watchful driver.
Please consult Fig. 4 more simultaneously, user mode embodiment schematic diagram when Fig. 4 prevents that for the utility model the electric shock shaking device of tired blue-tooth device is installed on the safety belt, as shown in the figure, supra-aural bluetooth body 10 can be connected control with several shaking devices 34 that shocks by electricity, and described electric shock shaking device 34 is arranged in the car on a steering wheel 36, safety belt 38, the driver seat 40 (cooperates referring to Fig. 3), make described steering wheel 36, safety belt 38, driver seat 40 can carry out the signal transmission with supra-aural bluetooth body 10.Supra-aural bluetooth body 10 also further can be connected with sound equipment in the car 42, in the time of needs, by the unlatching of sound equipment 42 in the supra-aural bluetooth body control car.
