Description
Technical field
The utility model belongs to car lighting and alarm equipment field, and in particular to a kind of for improving travel safety
Variable reversing light and orientation loudspeaker alarm equipment.
Background technology
Automobile on road is more and more, and traffic accident, especially rear-end collision often occurs.It refers to same track to knock into the back
The rear car and front truck of traveling are trailed when row, and the accident that rear car front bumps against with the front truck tailstock, the main reason for causing to knock into the back is
Caused by rear car follow-up is smaller than minimum safe distance or driver's delay of response.For the front truck of normally travel, chase after
Tail accident, which is a kind of typical passive accident, can spend and much need not although front truck driver need not undertake accident responsibility
The time and efforts wanted goes process accident.In current automobile safety system, and not comprising the active alarm for car rear-end
Equipment, so front truck driver lacks the method for ensureing and oneself not knocked into the back.The frequency that accident in order to reduce rear-end collision occurs,
The main reason for needing for rear-end collision installs the active alarm equipment for preventing car rear-end on vehicle, can be rear
Vehicle follow-up spacing prompts rear car driver to slow down immediately when too small, and after capable of more clearly being reminded in vehicle brake
Vehicle driver concentrates one's energy to take care.
In order to allow rear car driver to be accurately received warning information, the tactile alarm of the alarm method that may be used, smell
Alarm, visual warning, auditory warning etc..Since front and back two cars are not connected directly, institute in a haptical manner with smell mode all
It is not easily achieved.And visual warning and auditory warning mode are more likely realized.The vehicle-brake taillight being commonly used is just
It is a kind of visual alerting schemes, when front truck driver steps on brake, brake taillight will flash the redlight, and remind rear car driver note
Meaning.But this scheme rear car driver can only see the two kinds of possibility that send out a warning and do not send out a warning, there is no methods to know front truck department
Machine is gently to touch on the brake or bring to a halt, and also can not just make more accurate counter-measure.There is a kind of brake of classification Dynamic Announce
Lamp can control the brightness of brake lamp, brake pedal using the aobvious wide display mode since intermediate according to the dynamics to touch on the brake
Deeper by depressing, the brightness of brake lamp is higher.But if on bright daytime, or when bad weather, rear car department
Machine is not easy to distinguish the bright dark variation of front truck brake lamp, and the car light intrinsic brightness of different automobile types is also different, all can
Puzzlement is brought to rear car driver, is difficult the effect for playing anticipation in practical applications.Therefore brightness change and inadequate is relied solely on,
Also needing to the significant difference of light and shade area just can be with.The scheme of another visual warning is that front truck prompts rear car with mist form
Emergency brake has occurred in driver, but smog can cause unnecessary road traffic to interfere, and needs to be replaced as often as possible raw material,
So not being optimal solution.The best approach of auditory warning is whistle, but car horn is generally towards front, sound
Sound is difficult to be heard by rear car driver.It can allow the drivers of all angles below if one loudspeaker is installed automobile rear so
All hear, but in fact only need remind rear car one people of driver can.So rear car can be allowed by being also required for one kind
While driver hears alarm sound, the surrounding impregnable sound alarm device of other drivers.
In conclusion in order to improve the safety in vehicle travel process, the generation of rear-end collision is avoided as far as possible, is needed
Design a kind of brake warning light area and brightness adjustable visual alerting schemes simultaneously, and a kind of dedicated for reminding rear car department
The auditory warning scheme of machine, and two schemes are merged, prevent car rear-end to rear car driver's active alarm.This programme
It can install and use on various motor vehicles, while also be helped for unmanned, more rich warning information is increasingly risen
Road conditions are more fully understood in automatic driving vehicle, improve safety coefficient.
