Description
Technical field
The invention belongs to vehicle active safety field, it is hidden not to encroach on occupant for field of intelligent control, more particularly to one kind
Private drive assist system.
Background technology
In modern society, automobile is not merely as transport facility, and turns into the daily life of people more and more
Indispensable life companion living, it is also of common occurrence to carry out temperament and interest activity in the car, and people is past after temperament and interest activity end
Toward have fatigue, leg is soft, notice not enough collects medium reaction physiologically, this safe driving operation to driver is unfavorable
's.If whether carrying out temperament and interest activity using conventional image or sound means identification occupant in the car, can exist again and invade
The risk of the privacy of evil vehicle occupant.
The content of the invention
To solve the above problems, the invention provides a kind of drive assist system, it, which is used, does not encroach on vehicle occupant's privacy
Collecting unit, whether identification occupant is carrying out temperament and interest activity, and after recognition result is confirmed, formulates the vehicle control of adaptation
System strategy.
The system includes collecting unit, processing unit and execution unit；
Collecting unit is installed on the infra red thermograph of roof with including neighbouring room mirror, and red for adjusting
The drive mechanism of the shooting angle of outside line thermal imaging system, collecting unit is closed when starting in parking of automobile, driving, for obtaining car
Interior thermal imaging picture, thermal imaging picture is the Temperature Distribution picture for only having profile, and can not show the appearance of people in picture
Looks, therefore the privacy for the person of being taken can be protected；
Pressure sensor is designed with in-car each seat, for determining the position of personnel, drive mechanism is according to personnel
Position adjustment infra red thermograph shooting angle, the scope of thermal imaging picture is concentrated on the position, avoid remaining position
Thermal source interference；
Processing unit receives the thermal imaging picture from collecting unit, first selects in frame out in predetermined temperature range
Region, in-car article is filtered out further according to the size in region, so as 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 in-car personnel's body temperature exceedes
First threshold or climbing speed exceed Second Threshold, then and then processing unit judges whether other staff body temperature also rises,
If so, then processing unit judges that in-car has temperament and interest activity；
Processing unit corrects the size of first, second threshold value according to the working order of on-board air conditioner, during air conditioner refrigerating, refrigeration
Temperature is often less than 1 DEG C of the first standard value, and processing unit turns down first, second threshold value 1%, and during air-conditioning heating, heating temperature is per high
In 1 DEG C of the second standard value, processing unit heightens first, second threshold value 1%；
Because direct stimulation and physical demands are larger caused by in-car temperament and interest activity, if in temperament and interest activity end in short-term
In continue to drive, the mood of driver's excitement is not yet calmed down, and notice can't be in complete set, and would generally feel body
Body fatigue particularly leg is aching and limp, feels hot and sleepy.Therefore, judge that in-car has the situation of temperament and interest activity in processing unit
Under, in the predetermined amount of time after thermal imaging system startup, if any personnel in thermal imaging picture are sitting in/returned to operator seat and start
Vehicle prepares to drive, then execution unit reduces the sensitivity of gas pedal and/or increases the sensitivity of brake pedal, when traveling speed
Active reduction of speed when more than 50 kilometers per hour is spent, to tackle the physiological reaction that driver is absent minded, leg is soft；Open vehicle-mounted
To tackle the physiological reaction of driver's heat, in-vehicle multi-media system plays the fast music of rhythm simultaneously for air-conditioning or increase air conditioning exhausting amount
Volume is tuned up to tackle the physiological reaction that driver is stranded.
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, notice not enough collects the auxiliary operation that medium physiological reaction makes driving safety, that is, the security for improving driving is protected again
The privacy of occupant is protected.
Brief description of the drawings
Fig. 1 shows the system architecture schematic diagram of the application；
Fig. 2 shows the system control process of the application.
Embodiment
With reference to the accompanying drawings, the function that the structure of the 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 is installed on the infra red thermograph 1.1 of roof with including neighbouring room mirror, and for adjusting infra red thermograph
The drive mechanism 1.2 of 1.1 shooting angle, collecting unit 1 is closed when starting in parking of automobile, driving, for obtaining in-car
Thermal imaging picture；
Pressure sensor 4 is designed with in-car each seat, for determining the position of personnel, the basis of drive mechanism 1.2
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 in-car article, so as 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 in-car personnel's body temperature exceedes
First threshold or climbing speed exceed Second Threshold, then and then processing unit judges whether other staff body temperature also rises,
If so, then processing unit judges that in-car has temperament and interest activity；
Processing unit 2 corrects the size of 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 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 processing unit 2 heightens first, second threshold value 1%；
In the case where processing unit 2 judges that in-car has temperament and interest activity, the scheduled time after the startup of thermal imaging system 1.1
In section, if any personnel in thermal imaging picture are sitting in/returned to the concurrent motor-car of operator seat and prepare to drive, execution unit 3 subtracts
The sensitivity of small gas pedal and/or the sensitivity for increasing brake pedal, when travel speed more than 50 kilometers per hour when actively
Reduction of speed, to tackle the physiological reaction that driver is absent minded, leg is soft；On-board air conditioner or increase air conditioning exhausting amount are opened to answer
To the physiological reaction of driver's heat, in-vehicle multi-media system plays the fast music of rhythm and tunes up what volume was stranded to tackle driver
Physiological reaction.
