Abstract
A method for indicating the distance of a vehicle running on a highway in a foggy day. A method for prompting the distance between the front vehicle and the rear vehicle when the vehicle is running on highway in fog day features that the driver of the rear vehicle can find the front vehicle in advance and estimate the distance between the front vehicle and the rear vehicle and the speed of the front vehicle. The specific scheme is that two parallel light sources are respectively arranged on two sides of the rear part of the automobile, when the automobile encounters the weather with low visibility such as dense fog and the like, the parallel light sources are started to emit two parallel light beams towards the rear of the automobile, so that the two parallel light beams are intersected at a uniformly specified distance and height behind the automobile, the visible distance is long due to the concentrated light of the parallel light beams, a driver of a vehicle immediately behind the driver can see the intersected light beams at the front upper part of the automobile, and the distance between the intersection point of the light beams and the front automobile is uniformly specified, so that the driver of the rear automobile can estimate the distance between the automobile and the front automobile, and the speed of the front automobile can be estimated according to the change of the distance between the automobile and the intersection point, so that the speed of the automobile can.
Description
Technical field: a kind of method that the sign spacing is provided for the back car about express highway travelling in fog day front truck.
Background technology: the driving lamp of existing automobile tail, fog lamp etc. are all launched light in the mode of the conical surface, and light disperses, and visual range is near.When meeting the weather (thick fog, heavy rain, snowstorm, sandstorm) at the bottom of the visbility, vehicle following closely is difficult for finding preceding vehicle, when walking to the very near discovery preceding vehicle of spacing, has had little time to take measures, so rear-end collision takes place easily.Therefore under the prior art situation, for guaranteeing traffic safety, have to seal express highway during less than 50 meters at visbility.But owing to the very strong sudden and randomness that has of mist, often before freeway management department takes the sealing measure, just there has been rear-end collision to take place, caused casualties vehicle damage, traffic jam.
Summary of the invention: the invention reside in the vehicle that travels at express highway and when meeting the weather of low visibility such as thick fog, provide a kind of sign of pointing out spacing for another vehicle, make another vehicle can find preceding vehicle in advance, and can estimate and the distance of front truck and the speed of a motor vehicle of front truck.Technical scheme of the present invention is: respectively adorn a source of parallel light in the both sides of automobile rear, when meeting the weather of low visibility such as thick fog, open source of parallel light, make it penetrate the twice straight beam, unified predetermined distance behind car and height (eyes with not direct projection dais automobilist are advisable) intersect.Because the light of straight beam is concentrated, visual range is far away, automobilist following closely can see crossing light beam in this car front upper place, because of the distance of the joint of light beam and front truck is unified regulation, the driver of back car can estimate the distance of Ben Che and front truck thus, and can estimate the speed of a motor vehicle of front truck according to the variation of Ben Che and light beam joint distance, to regulate and control the speed of a motor vehicle of oneself, avoid the generation of rear-end collision.
The specific embodiment: respectively adorn a guide lamp in the automobile rear both sides, open guide lamp when meeting the weather of low visibility such as thick fog, penetrate the twice straight beam behind car, make two straight beams intersect at 30 meters behind the car, the joining height is 2.5 meters.Like this when visbility is 50 meters, the driver sees the driving situation that just can know the vehicle that exercise at 80 meters, the place ahead behind the crossing light beam of front upper place.For the regulation and control speed of a motor vehicle provides than plenty of time the generation that avoids traffic accident.
Claims (1)
- The express highway travelling in fog day shows apart from method.Front truck provides the method that indicates spacing for the back car during express highway travelling in fog day.It is characterized in that respectively adorning a source of parallel light, open source of parallel light when meeting the weather of low visibility such as thick fog, make it penetrate twice straight beam, the unified predetermined distance behind car and highly crossing in the both sides, rear portion of automobile.
