Description
Technical field
The invention belongs to systems technology field, more particularly to a kind of intelligent vehicle high beam anticollision system and its method.
Background technology
With the fast development of auto industry and the continuous improvement of running car performance, the safety of automobile is increasingly
Paid attention to by people, effect of the active safety technologies played in vehicle safety is especially prominent, what it can effectively prevent accident
Occur.
In the case of normally travel, often some car owners are not allowed to keep traffic rules, and when night opens high beam, cause pair
Influenced to lead to not normally travel by distance light to vehicle, it is serious to cause because driver can not see surface conditions clearly
Traffic accident.
So a kind of correct detection front of invention whether has high beam vehicle and the system for making danger judgement is that extremely have
It is necessary.
Invention content
Present invention aims at a kind of intelligent vehicle high beam anticollision system of offer and its methods.
A kind of intelligent vehicle high beam anticollision system and its method, which is characterized in that be by detecting vehicle front vehicle
It is no to have opening high beam and carry out danger judgement, judge that vehicle whether there is risk of collision and make prompt and specifically includes following step
Suddenly,
Step 1：Whether detection vehicle front opens car light, if repeating step 1 without car light is opened, if opening car light skips to step
Two；
Step 2：Start the luminance detection device in front of operator seat, if brightness value skips to step 3 more than default threshold value, if
See that brightness value skips to step 1 less than default threshold value；
Step 3：Whether detection front and/or right front have mobile object, if front has mobile object to skip to step 4, if
Right front has mobile object to skip to step 5, if having detected that mobile object skips to step 1；
Step 4：High beam vehicle distances S and speed V is obtained by speed detector and distance detection device, obtains itself
Car speed V1, front vehicle speed V2 calculate the time T to cross with opposed vehicle with front distance S1, judge when
Between whether have the risk mutually collided in T, if thering is the wind direction mutually collided to skip to step 6 in time T, if inside time T
Step 1 is then skipped in the presence of the wind direction mutually collided；
Step 5：Obtain the right pedestrian obtains every trade people and vehicle distance S3 in vehicle distance S2, time T1, judges
The angle value A relative to vehicle of pedestrian's walking with whether reach pre-set threshold, if reaching pre-set value skips to step 9, if
Not up to pre-set value then skips to step 1；
Step 6：Judge whether reach safe distance with front vehicles spacing, is adjusted if being not up to safe distance with front vehicles
Step 7 processed, modulation step eight if entering safe distance with front vehicles；
Step 7：Voice prompt user is slowed down；
Step 8：The automatic retarding of vehicle is carried out until being more than except safe distance by control centre, and skips to step 1；
Step 9：Judge whether can be gone on the track residing for vehicle in time T, if being gone in time T on itself track
Step 1 is skipped to if skipping to step 8 and not given birth to track.
Wherein, affiliated detection device is radar detection device, detects itself track respectively, on opposite track and the right track
Upper driving vehicle, detection range are the movement speed and distance for the object walked in 50M.
Wherein, according to described in step 4, by first time detecting distance S2, vehicle traveling distance S4 passes through in time T
It is calculated at a distance from second of vehicle and first time pedestrian with the speed and time T of pedestrian's walking, to calculate S5's and S1
Angle, if angle value judges to walk into road more than 90 degree, if judging to walk on its road less than 90 degree.
Wherein, according to luminance sensor is connected at its operator seat front described in step 2, if brightness value is more than people's sight
Received range then sends a signal to processor.
Wherein, according to wherein pedestrian reacquires distance, the range of T1 not 1 ~ 2 second by the T1 times described in step 5.
Advantageous effect：
The present invention judges whether that can influence driver drives according to the brightness of front distance light, by the row for judging front and right front
The movement track of people judges to whether there is risk of collision with vehicle, walks out in time and judge and make voice prompt, if reaching
The generation that action avoids traffic accident is made when safe distance in time.
Description of the drawings
Fig. 1 is a kind of intelligent vehicle high beam anticollision system of the present invention and its flow chart of method.
Specific implementation mode
Fig. 1 is a kind of intelligent vehicle high beam anticollision system and its flow chart of method, as shown in Figure 1, the present invention is implemented
The judgment method of example has following steps：
A kind of intelligent vehicle high beam anticollision system and its method, which is characterized in that left when vehicle traveling is on normal lane
Side is opposite track, and the right is pavement, and what the opposite track uplink of detection approached crosses vehicle two, whether opens high beam,
If detecting the vehicular high beam modulating signal for travelling and on opposite track on the glass in front of the operator seat of main vehicle, in front of operator seat
Shading value be more than the range that is received of people, where system detects main vehicle automatically in front of track and on the pavement of the right either with or without
Vehicle and pedestrian, if detecting that there is vehicle in main front side, first according to the distance of the speed of itself and opposite track vehicle
It is calculated with the speed of opposite track vehicle vehicle and opposite track vehicle crosses time T used, pass through T=S/（V0+V1）Because
After crossing illumination just do not have people can Self-operating vehicle, only in time T when danger can not operate, calculating
Judge whether the distance of vehicle traveling can be at a distance from front vehicles traveling except safe distance in time T, if
Just prompt car owner is slowed down in advance within safe distance, if being exactly foolproof, detection the right row except safe distance
The direction of star traveling, it is rectangular to be judged by angle value, main vehicle is calculated at a distance from pedestrian by two different time sections, and row
The speed of travel of people and time may determine that the walking angle of pedestrian by the cosine law of triangle, if pedestrian is past
A-road walking, judge in advance in time and car owner prompted to slow down, if A-road be found that pedestrian and safe distance it
Interior, timely traveling brake processing avoids that traffic accident is caused to specifically include following steps,
Step 1：Whether detection vehicle front opens car light, if repeating step 1 without car light is opened, if opening car light skips to step
Two；
Step 2：Start the luminance detection device in front of operator seat, if brightness value skips to step 3 more than default threshold value, if
See that brightness value skips to step 1 less than default threshold value；
Step 3：Whether detection front and/or right front have mobile object, if front has mobile object to skip to step 4, if
Right front has mobile object to skip to step 5, if having detected that mobile object skips to step 1；
