Description
Technical field
The invention belongs to vehicle active safety field, field of intelligent control, more particularly to a kind of driving based on infrared identification
Sail safety assisting system.
Background technology
In modern society, automobile be not merely as transport facility, and more and more become the daily life of people
Indispensable life companion living, it is also commonplace to carry out temperament and interest activity in the car, and people is past after temperament and interest activity end
Fatigue, leg is soft, attention not enough collects medium reaction physiologically toward having, this is unfavorable to the safe driving operation of driver
's.If whether carrying out temperament and interest activity using conventional image or sound means identification occupant in the car, and can exist and invade
The risk of the privacy of evil vehicle occupant.
Invention content
To solve the above problems, the present invention provides a kind of Driving safety assistant system, use that not encroach on vehicle occupant hidden
Private collecting unit, whether identification occupant is carrying out temperament and interest activity, and after confirming recognition result, formulates the vehicle of adaptation
Safety control strategy.
The system includes collecting unit, processing unit and execution unit；
Collecting unit include neighbouring room mirror be installed on the infra red thermograph of roof, and it is red for adjusting
The driving mechanism of the shooting angle of outside line thermal imaging system, collecting unit is closed when starting in parking of automobile, driving, for obtaining vehicle
Interior thermal imaging picture, thermal imaging picture are that only have contoured Temperature Distribution picture, and cannot show the appearance of people in picture
Looks, therefore the privacy for the person of being taken can be protected；
It is designed with pressure sensor on interior each seat, the position for determining personnel, driving mechanism is according to personnel
Position adjustment infra red thermograph shooting angle, so that the range of thermal imaging picture is concentrated on the position, avoid remaining position
Heat source interference；
Processing unit receives the thermal imaging picture from collecting unit, first selects in frame out in predetermined temperature range
Region, interior article is filtered out further according to the size in region, to identify the occupant's in thermal imaging picture
Quantity, and record the body temperature and Temperature changing of occupant；
In the case that the quantity of personnel is more than one in the car, when the ascensional range of any one interior personnel's body temperature is more than
First threshold or climbing speed are more than second threshold, then and then processing unit judges whether other staff body temperature also rises,
If so, processing unit judges that car has temperament and interest activity；
Processing unit corrects the size of the first, second threshold value according to the working order of on-board air conditioner, when air conditioner refrigerating, refrigeration
Temperature is often less than 1 DEG C of the first standard value, and processing unit turns down the first, second threshold value 1%, and when air-conditioning heating, heating temperature is per high
In 1 DEG C of the second standard value, the first, second threshold value 1% is turned up in processing unit；
Since direct stimulation and physical demands caused by interior temperament and interest activity are larger, if temperament and interest activity end in short-term
In continue to drive, the mood of driver's excitement is not yet calmed down, and attention can't be in complete set, and would generally feel body
Body fatigue especially leg is aching and limp, therefore, judges that car has that temperament and interest is movable in processing unit, is opened in thermal imaging system
In predetermined amount of time after dynamic, if any personnel in thermal imaging picture are sitting in/return to the concurrent motor-car of operator seat and prepare to drive,
Then execution unit carries out vehicle safety control, reduces the sensitivity of gas pedal and/or increases the sensitivity of brake pedal, works as row
Sail speed be more than 50 kilometers per hour when active reduction of speed.
The present invention using not encroaching on the collecting unit of vehicle occupant's privacy, for fatigue of the people after temperament and interest activity end,
Leg is soft, attention not enough collects the auxiliary operation that medium physiological reaction makes driving safety, that is, the safety for improving driving is protected again
The privacy of occupant is protected.
Description of the drawings
Fig. 1 shows the system structure schematic diagram of the application；
Fig. 2 shows the system control process of the application.
Specific implementation mode
With reference to the accompanying drawings, the function that the structure of this system is described in detail and is realized.
As shown in Figure 1, Driving safety assistant system includes collecting unit 1, processing unit 2 and execution unit 3, collecting unit
1 include neighbouring room mirror be installed on the infra red thermograph 1.1 of roof, and for adjusting infra red thermograph
The driving mechanism 1.2 of 1.1 shooting angle, collecting unit 1 is closed when starting in parking of automobile, driving, for obtaining car
Thermal imaging picture；
It is designed with pressure sensor 4 on interior each seat, the position for determining personnel, 1.2 basis of driving mechanism
The shooting angle of the position adjustment infra red thermograph 1.1 of personnel；
As shown in Fig. 2, processing unit 2 receives the thermal imaging picture from collecting unit 1, first select in frame out in pre-
The region in temperature range (the preferably common body temperature of human body, 35-38 DEG C) is determined, further according to the size mistake in region
Filter interior article, to identify the quantity of the occupant in thermal imaging picture, and record occupant body temperature and
Temperature changing；
In the case that the quantity of personnel is more than one in the car, when the ascensional range of any one interior personnel's body temperature is more than
First threshold or climbing speed are more than second threshold, then and then processing unit judges whether other staff body temperature also rises,
If so, processing unit judges that car has temperament and interest activity；
Processing unit 2 corrects the size of the first, second threshold value according to the working order of on-board air conditioner 5, when air-conditioning 5 freezes,
Cryogenic temperature is often less than 1 DEG C of the first standard value, and processing unit 2 turns down the first, second threshold value 1%, when air-conditioning 5 heats, heating temperature
Degree is often higher than 1 DEG C of the second standard value, and the first, second threshold value 1% is turned up in processing unit 2；
Since direct stimulation and physical demands caused by interior temperament and interest activity are larger, if temperament and interest activity end in short-term
In continue to drive, the mood of driver's excitement is not yet calmed down, and attention can't be in complete set, and would generally feel body
Body fatigue especially leg is aching and limp, therefore, judges that car has temperament and interest movable in processing unit 2, in thermal imaging system
In predetermined amount of time after 1.1 startups, if any personnel in thermal imaging picture are sitting in/return to operator seat, concurrent motor-car prepares
It drives, then execution unit 3 carries out vehicle safety control, including but not limited to reduces the sensitivity of gas pedal and/or increases system
The sensitivity of dynamic pedal, when travel speed be more than 50 kilometers per hour when the operations such as active reduction of speed.
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.
