Description
Technical field
The intelligence controlling device of a kind of automatic detection speed of a motor vehicle of the present invention, spacing relate to a kind of can detect automatically the speed of a motor vehicle and spacing, the speed of a motor vehicle surpass limit or spacing surpass when limiting can auto alarm control setup.
Background technology
According to adding up in recent years, the speed of a motor vehicle and inappropriate spacing too fast in the vehicle ' are one of principal elements of bringing out traffic accident, keep the road speed of safety and spacing to become one of key content that ensures the vast traffic participant security of the lives and property.
Hypervelocity can influence the accuracy that steerman is observed, judged.Discover that the speed of a motor vehicle is high more, the steerman viewpoint is far away more, the visual field is narrow more.According to experiment, if the eyesight of people when static be 1.2, when 60 kilometers of car speed per hours, its eyesight reduces to 0.6.Particularly more straight owing to the road surface at express highway, use Correct Lane, the roadside does not have trees and building is few, and the object of reference that chaufeur is grasped the speed of a motor vehicle under steam is few, is just exceeding the speed limit unconsciously.
Hypervelocity and near excessively spacing can reduce driver reaction time.In the actual traffic settlement of accident, often there is the accident driver to say that oneself " reacted and do not come " at that time.Discover that if car speed is 90 kilometers/hour, promptly per second travels 25 meters, if abnormal condition occur in 25 meters of the vehicle fronts, does not wait the driver to judge reaction, vehicle has been flushed at the moment, exceeds the speed limit very easily to cause traffic accident.Certainly the automobile that has is when sending out accident, and the speed of a motor vehicle does not surpass 110 kilometers/hour, still, has surpassed weather, the speed of a motor vehicle that road conditions, vehicle condition allowed in the driving, can not travel to guarantee safe speed, and this in fact also is a hypervelocity.
But what can not ignore is in all traffic accidents, though have in part because of causing by driver hypervelocity wholly or in part, most traffic accident be since bad steering be accustomed to cause.Nearly all collision all is attributable to negligence, the particularly absent minded and relative speed of a motor vehicle or the route of judging other vehicles by accident.And the cause great majority of these collisions are too near with car just, and spacing is too short.The state that automobile in travelling will run into car and quicken to overtake other vehicles through regular meeting.Should keep certain distance with the fwd vehicle during cruising, spacing just causes accident on the contrary in continuous minimizing easily in case find emergency situation when still overtaking other vehicles.
