Description
Technical field
The invention belongs to vehicle safety field of auxiliary, field of biological recognition, more particularly to a kind of rows based on bio-identification
Vehicle safety aid.
Background technology
According to statistics, most of traffic accident is caused by due to the undesirable driving behavior of driver in the world every year, such as
It eats in driving procedure.The prior art such as CN203020194U, CN102567743A are driven based on video image judgement
Whether on the feed the person of sailing, and then sends out prompting to driver.The accuracy that this mode judges is not high, and the algorithm of image procossing
Complexity is unfavorable for promoting.
Invention content
To solve the above problems, the present invention provides a kind of driving safety auxiliary devices, including：Detection unit, analysis are single
Member and execution unit, detection unit are used to acquire the biological data of 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 headset and the displacement close to driver's cheek side set on bluetooth headset
Sensor, for microphone for monitoring whether driver is speaking, displacement sensor is used to monitor the movement of driver's jaw portion movement
Displacement and run duration；
In the case where driver wears and connects bluetooth headset, when microphone monitors driver not when speaking, point
The jaw portion motion conditions for the driver that analysis unit is monitored according to displacement sensor establish the feed cycle of driver, feed cycle
Including the intermittent periods between chewing period and two neighboring chewing period, the Masticatory frequency characterization feed food in the period is chewed
Soft or hard degree, the volume size of the jaw portion motion amplitude characterization feed food of chewing for the first time；
When the jaw portion motion amplitude that the Masticatory frequency that one was chewed in the period is more than first threshold or chews for the first time is more than
Second threshold, analytic unit judge driver's food difficult to deal on the feed, and execution unit carries out the safety of sound or light at this time
It reminds；
It is more than the 4th when intermittent periods are less than third threshold value or chew the number that the period occurs in the first predetermined amount of time
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, execution unit makes the hydraulic pressure of steering wheel or the operation power of electric booster system increase at this time,
Steering wheel is set to be easier by driver's one-handed performance；
When feed circulation continuous second predetermined amount of time longer than the first predetermined amount of time, analytic unit judges to drive
Person feeds in long-time, this will give driving to drive and bring great security risk, and therefore, execution unit control at this time, which reduces, starts
The distributive value or air inflow of machine carry out active reduction of speed to reduce engine speed, and/or reduce 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
The present invention is for this bad steering custom is fed in driving, using suitable and accurate safety control strategy, greatly
The earth improves travel safety.
Description of the drawings
Fig. 1 shows the structure principle chart of the application；
Fig. 2 shows the feed of the application cycles.
Specific implementation mode
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 auxiliary device 1 based on bio-identification includes：It detection unit 2, analytic unit 3 and holds
Row unit 4, detection unit 2 is used to acquire the biological data of driver, and is believed by vehicle bluetooth communication agreement and 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 headset and set on bluetooth headset close to driver's cheek side
Displacement sensor 2.2, microphone 2.1 is for monitoring whether driver is speaking, and displacement sensor 2.2 is for monitoring driver's jaw
The moving displacement and run duration of portion's movement；
In the case where driver wears and connects bluetooth headset, when microphone monitors driver not when speaking, point
The jaw portion motion conditions for the driver that analysis unit is monitored according to displacement sensor establish the feed cycle of driver, such as Fig. 2 institutes
Show, feed cycle includes the intermittent periods 6 chewed between period 5 and two neighboring chewing period 5, chews the chewing in the period 5
The soft or hard degree of number characterization feed food, the jaw portion motion amplitude s chewed for the first time1The volume size of characterization feed food；
When the Masticatory frequency that one was chewed in the period 5 is more than first threshold (such as 4 times) or the jaw portion fortune of chewing for the first time
Dynamic amplitude s1More than second threshold, analytic unit 3 judges driver's food difficult to deal on the feed, at this time execution unit 4 into
The safety prompt function of row sound or light；
When intermittent periods 6 are less than third threshold value or in the first predetermined amount of time T1It is interior chewing the period 5 occur number be more than
4th threshold value (such as 4 times), analytic unit 3 judge that driver is repeatedly feeding, and repeatedly the hand of driver is general when feed
Rate will for feeding and multiple off-direction disk, therefore, execution unit 4 makes the hydraulic pressure or electric booster system of steering wheel at this time
Operation power increase, make steering wheel be easier by driver's one-handed performance；
As feed circulation continuous the first predetermined amount of time T of ratio1The second longer predetermined amount of time T2, the judgement of analytic unit 3
Driver feeds in long-time, this will give driving to drive and bring great security risk, and therefore, the control of execution unit 4 at this time subtracts
The distributive value or air inflow of puffer carry out active reduction of speed, and/or reduce the spirit of gas pedal to reduce engine speed
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 the spirit and scope of the invention as describing in general manner,
Various variations and/or modification can be carried out to 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.
