Description
Technical field
The invention belongs to power engineering working truck field, relate in particular to a kind of method and device thereof for eliminating the 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 (comprise 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 complicated 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.; Be at present 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, collision caution system etc. are arranged.
On some medium and high classes automobiles, is furnished with a kind of blind monitoring system.What is 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 the blind area, can point out the driver at back mirror or other assigned addresses, thereby inform when the driver is the preferably opportunity of " doubling ", decrease the accident that occurs 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 behind the car 9 meters, each wide 3.5 meters zone, both sides, this is just in the Vehicle Driving Cycle, an invisible visual dead angle from inside rear-view mirror and outer rearview mirror, be referred to as the blind area, if Vehicle Driving Cycle is arranged in the blind area, this car " modified line " formed dangerous, a red light on the vehicle A post (column between vehicle front windshield and the driver door) will glimmer, and send the buzz alarm, chaufeur is pointed out, at this moment " modified line " danger.
But for the consideration of manufacturing cost, these are main, the passive security technology all is to be provided on some medium and high classes cars or the cross-country car usually, for the such Contraction in Site vehicle of power engineering vehicle, rarely have configuration.
And, in actual field driver behavior operation process, because the existence of 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 of the place of power engineering vehicle in the surface condition complexity and travels and bring very big difficulty and inconvenience, 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 in the vehicle both sides, the rear to the blind area warn, 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 restriction that the repacking of vehicle is met the various regulations of vehicle management department, also is a difficult point in the actual vehicle facility management.
How under the condition of the various auxiliary driving devices (such as Reverse Sensor, inside/outside back mirror etc.) that existing vehicle is equipped with, the cost of least cost, help driver's observation to vehicle off front wheel the place ahead or the actual ground situation of side coil, making it grasp as far as possible all sidedly the field ground situation of outside vehicle (particularly front, the side coil of vehicle off front wheel), is problem in the urgent need to address in the actual field work.
Summary of the invention
