Description
Technical field
The invention belongs to vehicle safety field of auxiliary, field of biological recognition, more particularly to a kind of row based on bio-identification
Car safety aid.
Background technology
According to statistics, most of traffic accident is due to that the bad driving behavior of driver is caused in the world every year, for example
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, 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 receives the biological data from detection unit, and analyzes the current specific feed shape of driver
State, execution unit controls 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, microphone is used to monitor whether driver is speaking, and displacement transducer is used for the motion for monitoring the motion of driver's jaw portion
Displacement and run duration；
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 is monitored according to displacement transducer set up the feed circulation of driver, feed circulation
Including chewing the intermittent periods between period and two neighboring chewing 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 a Masticatory frequency chewed in the period exceedes first threshold or chewed for the first time exceedes
Second Threshold, analytic unit judges 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 times of period appearance is chewed in the first predetermined amount of time more than the 4th
Threshold value, analytic unit judges that driver is repeatedly feeding, repeatedly during feed the hand maximum probability of driver will be in order to take food
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 bring great potential safety hazard to driving driving, therefore, and 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 reduction gas pedal sensitivity and/
Or the sensitivity of brake pedal is improved, to improve the driving safety grade of vehicle.
Further, first, second, third, fourth threshold value can be had by meter panel of motor vehicle operation interface
The setting of body value
It is of the invention to be accustomed to for feeding this bad steering in driving, the accurate safety control strategy using suitable, 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 structure of the present apparatus and the function of being realized is described in detail.
As shown in figure 1, the driving safety auxiliary device 1 based on bio-identification includes：Detection unit 2, analytic unit 3 and hold
Row unit 4, detection unit 2 is used for the biological data for gathering driver, and is believed by vehicle bluetooth communication agreement with analytic unit 3
Number connection, analytic unit 4 receives the biological data from detection unit 2, and analyzes the current specific fed conditions of driver,
Execution unit 4 controls the security setting of vehicle according to specific fed conditions；
The microphone 2.1 of detection unit 2 including bluetooth earphone and press close to driver's cheek side located at bluetooth earphone
Displacement transducer 2.2, microphone 2.1 is used to monitor whether driver is speaking, and displacement transducer 2.2 is used to monitor driver's jaw
The moving displacement and run duration of portion's motion；
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 is monitored according to displacement transducer set up 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 of times 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；
The jaw portion fortune for exceeding first threshold (such as 4 times) when a Masticatory frequency chewed in the period 5 or chewing 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 of times for chewing the appearance of period 5 exceedes
4th threshold value (such as 4 times), analytic unit 3 judges that driver is repeatedly feeding, and repeatedly the hand of driver is general during feed
Rate will be in order to take food 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 bring great potential safety hazard to driving driving, therefore, and the now control of execution unit 4 subtracts
The distributive value or air inflow of puffer, to reduce engine speed, carry out active reduction of speed, 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.
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.
