Description
Technical field
It is the invention belongs to field of automobile electronic control, more particularly to a kind of to be monitored with camera and image object identification technology
The driver safety auxiliary system of Automobile Right front blind-area.
Background technology
In order to improve drive safety, people take up to develop various safe driving assistant systems.So-called driving is " blind
Area ", the dead angle that sight generates when referring to driver's operating motor vehicles and the place being unaware of, blind area is vehicle structure institute mostly
Caused, since vehicle is different, the size of all kinds of vehicle blind areas is also different, wherein being exactly to drive in the right front of vehicle
One of blind area for the person of sailing.The right front blind-area that vehicle is equipped at present monitors system, mainly by groups such as ultrasonic radar and control modules
At system operating conditions are determined by ultrasonic wave physical characteristic, and investigative range can not meet people there are certain blind area and wrong report possibility
Demand to automobile high safety driving.
Invention content
The purpose of the present invention is designing a kind of right front blind-area visual monitoring alarm system of vehicle, provided reliably for driver
Right front blind-area monitoring and early warning.
The right front blind-area visual monitoring alarm system of vehicle of the present invention by control unit and respectively with described control unit phase
Camera even, steering wheel angle sensor, alarm are constituted, and the camera is also connected with display；The camera will
The image transmission of the right front blind-area of vehicle monitored to control unit and display, described control unit according to the image received into
Row judges, when right front, object enters vehicle right front blind-area, control unit passes through alarm and carries out blind area warning；Before the right side
Square object body and when being smaller than preset distance of this vehicle, control unit utilization orientation disk rotary angle transmitter obtain current steering wheel
Angular signal, if driver does not change vehicle heading, control unit carries out collision warning, the blind area by alarm
It warns different from the signal of collision warning.
Further, described control unit is connect with vehicle speed sensor, vehicle right front blind-area visual monitoring alarm system
System works when speed is within the scope of preset vehicle speed.Specifically, it is proposed that the right front blind-area visual monitoring alarm system of vehicle exists
Speed works when being within the scope of 1~5 kilometer/hour, and when speed is too low, driver has a time enough reaction, and speed mistake
Gao Shi, driver can find that the barrier of right front more at a distance in advance, therefore all not need blind area early warning.
Further, described control unit is connected with manual switch, the right front blind-area visual monitoring alarm system of vehicle
It is turned on or off using manual switch；The priority of the manual switch is higher than the priority of vehicle speed sensor.By setting
Manual switch is set, driver's unrestricted choice can be allowed whether to open blind area warning function.
Specifically, the alarm is buzzer and the LED being installed on the A columns of right side in instrument；The blind area warning
It is lighted for the LED on the A columns of right side；The collision warning is buzzer rings in instrument and the flickers of the LED on the A columns of right side.It compares
In the signal of blind area warning, the signal for colliding warning is easier to cause the concern of driver.
Further, described control unit is connected with radar, and control unit is believed according to received image and/or radar
Number vehicle is calculated at a distance from the object of right front, to improve the precision of Distance Judgment.
Further, described control unit is connected with speed control unit, control unit gear be in advance or after
Alarm function is just opened when moving back gear.When a vehicle is at rest, even if collision is not present if having barrier in right front blind-area
Danger, there is no need to blind area early warning.
The right front blind-area visual monitoring alarm system of vehicle of the present invention by camera come the case where detecting right front blind-area,
In the case that vehicle right side blind area is there are object, according to object, the situation at a distance from this vehicle carries system to carry out different early warning
Show, reliable reference is provided for the driving of driver.
Description of the drawings
Fig. 1 is the schematic diagram of the right front blind-area visual monitoring alarm system of vehicle of the present invention.
Specific implementation mode
Below against attached drawing, by the description to embodiment, for example involved to the specific implementation mode of the present invention is each
Mutual alignment and connection relation, the effect of each section and operation principle between the shape of component, construction, each section etc. are made into one
The detailed description of step.
Embodiment 1：
As shown, the right front blind-area visual monitoring alarm system of the vehicle of the present embodiment by manual switch, be mounted on it is right outer
The right preceding camera of rearview mirror, control unit, display（That is vehicle-carrying DVD）, vehicle speed sensor, steering wheel angle sensor, shelves
Position control unit, it is right before LED light on A columns, buzzer composition in instrument, wherein control unit respectively with manual switch, it is right before
Camera, control unit, display, vehicle speed sensor, steering wheel angle sensor, speed control unit, it is right before on A columns
Buzzer is connected in LED light, instrument, and right preceding camera is also connected with display；Wherein：
Manual switch：Offer system unlatching/shutdown signal；
Right preceding camera：Vehicle right front image information is obtained in real time, is supplied to display and control unit；
Control unit：Using the vehicle right front image information of acquisition, calculate vehicle and right front object it is horizontal away from
From judging whether alarm；
Display：Real-time display vehicle right front image information；
Vehicle speed sensor：Offer Velicle motion velocity signal itself；
Steering wheel angle sensor：The rotational angle signal of steering wheel is provided；
LED light：Carry out optics alarm；
Instrument buzzer：Carry out acoustical alarm prompt.
The operation principle of the right front blind-area visual monitoring alarm system of vehicle of the present embodiment is as follows：
Open system manual switch, right preceding camera are started to work.The camera being installed under right outside rear-view mirror constantly obtains
The image information of the one rectangle blind area in vehicle side right front, picture signal is taken to be transferred to display and control unit.Driver
Situation in the right front blind-area of vehicle can be observed by display, control unit obtains current gear and speed signal by CAN bus,
And speed is in a certain range（1~5 kilometer/hour）When system it is in running order.
When there is object to enter one rectangle blind zone range of vehicle right front, control unit sends blind area warning letter
Number, LED light lights on A columns.Control unit compares advanced technology by picture, compares and calculates right front blind-area at this time per frame image
The horizontal distance of interior object and vehicle, when distance is less than a certain setting value, right front blind-area monitoring modular is obtained by CAN bus
Steering wheel angle signal changes vehicle heading as driver does not beat steering wheel, and warning lamp can increase brightness and start to dodge
It is bright, while control unit control instrument buzzer carries out ring alarm, prompting driver to continue former direction running at this time may
It collides.The system can't impose restrictions on vehicle heading, and driver can be operated with manual switches and be turned on or off
System function.
It is worth noting that, control unit just opens alarm function when gear is in advance or retreating gear.
