Description
Technical field
The utility model relates to a kind of device improving traffic safety, is specifically related to a kind of device laser radar being carried out to ACTIVE CONTROL, belongs to the security fields of automobile.
Background technology
Along with the development of auto industry, improving constantly of living standards of the people, automobile has just like become the walking-replacing tool of everybody trip.But the continuous increase of automobile quantity, result also in taking place frequently of traffic hazard.In all locations of road traffic, can say that the situation of intersection is the most complicated, the particularly intersection in city, various vehicle collects, pedestrian density is large, be traffic hazard multiplely, so the traffic safety of intersection should cause our showing great attention to.Although traditional vehicle radar system constantly develops along with the progress of science and technology, can reduce as far as possible or avoid casualties and property loss, such as, but traditional fixed type automobile radar system still also exists problems, and detection angle is limited, can not realize the maximal cover to blind area.When travelling in intersection in the face of complicated road conditions, particularly automobile, driver cannot take into account the road conditions in all directions, there is huge potential safety hazard.
Therefore, be necessary that (such as bumper, securing band, air bag etc.) are studied the active safety of automobile on the basis of passive security, to improve the safety coefficient of automobile, the better safety of life and property of each traffic participant of protection.
Summary of the invention
The purpose of this utility model is to provide a kind of active control device improving the laser radar of intersection traffic safety.
The utility model is by servomotor, reductor, head bearing, taper roll bearing, turning axle, radar holder, support, top chock, step and control system composition, support is fixed on Vehicular body front, servomotor, reductor, head bearing and taper roll bearing are arranged on support, the output shaft of servomotor connects with the input shaft of reductor, the output shaft of reductor connects with turning axle, the upper and lower side of turning axle is located in head bearing and taper roll bearing respectively, in the top chock that head bearing and taper roll bearing are separately positioned on support and step, radar holder is fixing on the rotary shaft, radar holder can rotate with turning axle, control system is connected with servomotor and controls servomotor work.
Compared with prior art, tool has the following advantages the utility model:
1, traditional fixed type radar detection angle is limited, and there is very large blind area, laser radar of the present utility model can rotate applicable angle under the drive of servomotor, maximum coverage hole.
2, apply laser radar, detection angle is large, is 90 ~ 100 degree, and detection range is far away, is 80 ~ 90 meters, than the detection being more suitable for intersection.
3, after the traffic information that laser radar collects processes by analysis, if dangerous, driver can be reminded by the form of flashing lamp and voice.
4, improve the security that vehicle travels, particularly enhance the security at crossing intersection part turning driving.
Accompanying drawing explanation
Fig. 1 is the schematic perspective view of the utility model embodiment.
Embodiment
Refer to shown in Fig. 1, the present embodiment is by servomotor 1, reductor 2, head bearing 3, taper roll bearing 4, turning axle 5, radar holder 6, support 7, top chock 8, step 9 and control system 10 form, support 7 is fixed on Vehicular body front, servomotor 1, reductor 2, head bearing 3 and taper roll bearing 4 are arranged on support 7, the output shaft of servomotor 1 connects with the input shaft of reductor 2, the output shaft of reductor 2 connects with turning axle 5, the upper and lower side of turning axle 5 is located in head bearing 3 and taper roll bearing 4 respectively, in the top chock 8 that head bearing 3 and taper roll bearing 4 are separately positioned on support 7 and step 9, radar holder 6 is fixed on turning axle 5, radar holder 6 can rotate with turning axle 5, control system 10 is connected with servomotor 1 and controls servomotor 1 and works.
Described control system 10 is prior art, and its concrete structure and circuit repeat no more.
The course of work of the present embodiment:
Laser radar is arranged on radar holder 6, radar holder 6 can rotate with turning axle 5, first judge whether front has intersection by the GPS positioning system of control system 10, if, do not continue cycle criterion, if had, startup servomotor 1 controls laser radar and turns over the certain maximal cover of angle realization to blind area, next, judge whether steering indicating light is opened, if do not opened, then be judged as keeping straight on, if steering indicating light is opened, then continue to determine whether that left steering lamp is opened, if not being then judged as turning right, if left steering lamp is opened, then be judged as.Keep straight on, turn left and turn right be vehicle through intersection three kinds of different driving mode, the main hazard vehicle corresponding to each driving mode is different, need screen, and only processes main hazard vehicle.Next by speed pickup, Real-time Collection is carried out to the speed of this car, the speed of distance between Ben Che and main hazard vehicle and main hazard vehicle operating is measured by laser radar, it is dangerous whether analytical calculation main hazard vehicle can produce this car, if do not have danger, do not process, if dangerous, the form of warning lamp and prompt tone reminds driver to note.
