Description
Technical field
The utility model belongs to power engineering working truck field, relates in particular to a kind of for eliminating the device of driver's seat blind spot.
Background technology
In real work, various electrical equipments have and much all are mounted in the operating environment complexity, without the place of good road conditions or surface condition complexity.
Application and development along with mechanized construction, increasing large-scale power engineering truck (comprising electricity emergency car) is used to daily power construction, patrol and examine or field device maintenance, repairing work in, greatly improved the work efficiency of on-the-spot outdoor construction, repairing work.
Simultaneously, along with the complexity variation of working environment, various the travelling that the power engineering vehicle occurs/drive the class accident also increases thereupon.
In order to guarantee the driving safety of vehicle, each car production producer has adopted various active safetys, passive safety system in a large number, improve most possibly the driving safety performance of automobile, in these safety methods, that knows has safety strap, safety air bag, safety headrest, an anti-skid brake system etc.; At present in apply or on a large scale the technology of operational phase EBD (Electric Brakeforce Distribution), anti-slip regulation, electronic stabilizing control system, blind spot information system are arranged, collide caution system etc.
On some medium and high classes automobiles, is furnished with a kind of blind monitoring system.So-called blind monitoring system, exactly by radar, the first-class device of making a video recording, when Vehicle Driving Cycle, the blind area of vehicle both sides is surveyed, if there are other vehicles to enter blind area, can to the driver, be pointed out at back mirror or other assigned addresses, thereby inform when the driver is the preferably opportunity of " doubling ", decrease the accident occurred because of " doubling ".
For example, the BLIS(Blind Spot Information System of Volvo) blind spot information system, that a camera respectively is installed under two outside rear-view mirrors, can monitor after car 9 meters, each zone of wide 3.5 meters, both sides, this is just in Vehicle Driving Cycle, from inside rear-view mirror and an invisible visual dead angle in rearview mirror, be referred to as blind area, if Vehicle Driving Cycle is arranged in blind area, this car " modified line " is formed dangerous, a red light on vehicle A post (column between vehicle front windshield and driver door) will glimmer, and send the buzz alarm, chaufeur is pointed out, now " modified line " danger.
But for the consideration of manufacturing cost, these are main, the passive security technology is all to be provided on some medium and high classes cars or cross-country car usually, such Contraction in Site vehicle for the power engineering vehicle, rarely have configuration.
And, in actual field driver behavior operation process, existence due to inside and outside back mirror viewing blind zone, navigating mate normally can't be observed the actual ground situation of vehicle off front wheel the place ahead or side coil (being the side coil of right side A post), this gives moving and travelling and bring very big difficulty and inconvenience of the place of power engineering vehicle in the surface condition complexity, also has influence on the safety of Contraction in Site and smoothly, carry out fast.
If install above-mentioned blind spot information system additional for existing power engineering vehicle, the one, the repacking cost is higher, and can only be warned to Xiang De blind area, Zhong, rear, vehicle both sides, and a difficult problem is observed in the visual field that can't solve the place ahead, vehicle right side; The 2nd, this repacking often needs to relate to the change of the original control path part of automobile, and to the repacking of vehicle, also be subject to the restriction of the various regulations of vehicle management department of public security organ, vehicle management functional department is provided with very high threshold to remoulded car, how making the repacking of vehicle is met the restriction of the various regulations of vehicle management department, is also a difficult point in the actual vehicle facility management.
Under the condition of the various auxiliary driving devices (such as Reverse Sensor, inside/outside back mirror etc.) how to be equipped with at existing vehicle, the cost of least cost, help chaufeur to observe the actual ground situation of vehicle off front wheel the place ahead or side coil, make its grasp as far as possible all sidedly outside vehicle (particularly the vehicle off front wheel before, side coil) the field ground situation, be problem in the urgent need to address in actual field work.
