Description
Technical field
The invention belongs to vehicle safety field of auxiliary, field of biological recognition are more particularly to a kind of to be based on driver's biology number
According to driving safety device.
Background technology
According to statistics, caused by most of traffic accident is due to the bad driving behavior of driver in the world every year, such as
Eaten in driving procedure.Prior art such as CN203020194U, CN102567743A are to judge to drive based on video image
Whether on the feed the person of sailing, and then sends prompting to driver.The accuracy that this mode judges is not high, and the algorithm of image procossing
Complexity, it is unfavorable for promoting.
The content of the invention
To solve the above problems, the invention provides a kind of driving safety auxiliary device, including：Detection unit, analysis are single
Member and execution unit, detection unit are used for the biological data for gathering driver, and single with analysis by vehicle bluetooth communication agreement
First signal connection, analytic unit receive the biological data from detection unit, and analyze the current specific feed shape of driver
State, execution unit control the security setting of vehicle according to specific fed conditions；
Detection unit includes the microphone of bluetooth earphone and the displacement for pressing close to driver's cheek side located at bluetooth earphone
Sensor and humidity sensor, microphone are used to monitor whether driver is speaking, and displacement transducer is used to monitor driver's jaw
The moving displacement and run duration of portion's motion, humidity sensor are used for the perspiration situation for monitoring driver's skin surface；
In the case where driver wears and connects bluetooth earphone, when microphone monitors that driver is not speaking, point
The jaw portion motion conditions for the driver that analysis unit monitors according to displacement transducer establish the feed circulation of driver, feed circulation
Including chewing period and the two neighboring intermittent periods chewed between the period, chew the Masticatory frequency in the period and characterize feed food
Soft or hard degree, the jaw portion motion amplitude chewed for the first time characterizes the volume size of feed food；
When the jaw portion motion amplitude that the Masticatory frequency that one was chewed in the period exceedes first threshold or chewed for the first time exceedes
Second Threshold, analytic unit judge driver's food difficult to deal with the feed, and now execution unit carries out the safety of sound or light
Remind；
When intermittent periods are less than the 3rd threshold value or the number of period appearance is chewed in the first predetermined amount of time more than the 4th
Threshold value, analytic unit judge that driver is repeatedly feeding, repeatedly feed when driver a hand maximum probability will be for feeding
And multiple off-direction disk, therefore, now execution unit makes the operation power increase of the hydraulic pressure or electric booster system of steering wheel,
Steering wheel is set to be easier by driver's one-handed performance；
When feeding circulation continuous second predetermined amount of time longer than the first predetermined amount of time, analytic unit judges to drive
Person is fed in long-time, and this will give driving driving to bring great potential safety hazard, and therefore, now execution unit control reduction is started
The distributive value or air inflow of machine, to reduce engine speed, carry out active reduction of speed, and/or reduce gas pedal sensitivity and/
Or the sensitivity of brake pedal is improved, to improve the driving safety grade of vehicle.
During humidity sensor detects that driver is circulated on the feed, skin surface humidity increase, analytic unit is sentenced
Disconnected driver perspires because feeding irritable food, and now execution unit control makes the air output of the facial air outlet of on-board air conditioner
Increase and/or make the leaving air temp of on-board air conditioner to reduce.
Further, first, second, third, fourth threshold value can be had by meter panel of motor vehicle operation interface
The setting of body value
The present invention is for feeding this bad steering custom in driving, using suitable and accurate safety control strategy, greatly
The earth improves travel safety.
Brief description of the drawings
Fig. 1 shows the structure principle chart of the application；
Fig. 2 shows the feed circulation of the application.
Embodiment
With reference to the accompanying drawings, the function that the structure of the present apparatus is described in detail and is realized.
As shown in figure 1, the driving safety device 1 based on driver's biological data includes：Detection unit 2, the and of analytic unit 3
Execution unit 4, detection unit 2 is used for the biological data for gathering driver, and passes through vehicle bluetooth communication agreement and analytic unit 3
Signal connects, and analytic unit 4 receives the biological data from detection unit 2, and analyzes the current specific feed shape of driver
State, execution unit 4 control the security setting of vehicle according to specific fed conditions；
Detection unit 2 includes the microphone 2.1 of bluetooth earphone, located at the position for pressing close to driver's cheek side of bluetooth earphone
Displacement sensor 2.2 and humidity sensor 2.3, microphone 2.1 are used to monitor whether driver is speaking, and displacement transducer 2.2 is used
In the moving displacement and run duration of the motion of monitoring driver's jaw portion, humidity sensor 2.3 is used to monitor driver's skin surface
Perspiration situation；
In the case where driver wears and connects bluetooth earphone, when microphone monitors that driver is not speaking, point
The jaw portion motion conditions for the driver that analysis unit monitors according to displacement transducer establish the feed circulation of driver, such as Fig. 2 institutes
Show, feed circulation includes chewing period 5 and the two neighboring intermittent periods 6 chewed between the period 5, chews the chewing in the period 5
Number characterizes the soft or hard degree of feed food, the jaw portion motion amplitude s chewed for the first time1Characterize the volume size of feed food；
When the jaw portion fortune that the Masticatory frequency that one was chewed in the period 5 exceedes first threshold (such as 4 times) or chewed for the first time
Dynamic amplitude s1More than Second Threshold, analytic unit 3 judges driver's food difficult to deal with the feed, and now execution unit 4 enters
The safety prompt function of row sound or light；
When intermittent periods 6 are less than the 3rd threshold value or in the first predetermined amount of time T1The interior number for chewing the appearance of period 5 exceedes
4th threshold value (such as 4 times), analytic unit 3 judge that driver is repeatedly feeding, and repeatedly the hand of driver is general during feed
Rate will for feeding and multiple off-direction disk, therefore, now execution unit 4 makes the hydraulic pressure or electric booster system of steering wheel
Operation power increase, make steering wheel be easier by driver's one-handed performance；
As feed circulation continuous ratio the first predetermined amount of time T1The second longer predetermined amount of time T2, analytic unit 3 judges
Driver feeds in long-time, and this will give driving driving to bring great potential safety hazard, and therefore, the now control of execution unit 4 subtracts
The distributive value or air inflow of puffer, to reduce engine speed, active reduction of speed is carried out, and/or reduce the spirit of gas pedal
Sensitivity and/or the sensitivity for improving brake pedal, to improve the driving safety grade of vehicle.
During humidity sensor 2.3 detects that driver is circulated on the feed, skin surface humidity increase, analytic unit
Judge that driver perspires because feeding irritable food, now execution unit control makes the air-out of the facial air outlet of on-board air conditioner
Amount increases and/or reduces the leaving air temp of on-board air conditioner.
One skilled in the art would recognize that without departing substantially from as the spirit and scope of the invention described in general manner,
Various changes and/or modification can be carried out to the invention shown in each specific embodiment.Therefore, in terms of all
For, embodiment here is considered as illustrative and and non-limiting.Equally, the present invention includes any feature
Combination, the combination of any feature especially in Patent right requirement, even if the combination of this feature or feature is not in patent
It is explicitely stated in claim or each embodiment here.
