Description
Technical field
The present invention relates to vehicle electric field, and in particular to a kind of vehicle early warning method and device.
Background technology
" ten accident nine times fast ", drive over the speed limit and are referred to as " killer of road first ".Brought harm of driving over the speed limit is
Many, one is that security reliability is reduced；Two is that impact failure power is big when colliding, mostly serious accident；Three is in braking effect
On fruit, speed often doubles, and braking distance about increases by four times；Four is driver's psychentonia when driving over the speed limit, psychological and raw
Reason energy expenditure is big, easily fatigue；Five are travelled on bend, and the stability of vehicle is reduced, and speed is more fast easier to overturn
Accident.Therefore, forbid automobile overspeed very necessary, driver is usually used GPS navigator or is carried out using cyberdog etc.
Overspeed warning.Existing method for early warning is broadly divided into that early warning is tested the speed in fixation and flowing is tested the speed early warning.Fixation is tested the speed, and is by data
After collection, by data accumulating inside electronic chart or packet, during close speed measuring point, equipment can point out driver, front
There is electronic eye to test the speed.Typically, GPS navigator just possesses the ability that fixation is tested the speed.Flowing is tested the speed, and is, by radar detedtor, to visit
The radar wave that electronic eye is emitted is measured, driver will be automatically reminded to, there is speed measuring equipment in careful front.
But, no matter using any method for early warning, existing overspeed warning method is only capable of for speed measuring point or electronics
Eye carries out early warning, and for the section that still there is restriction speed without speed measuring point cannot then carry out early warning.For example, according to friendship
Logical law regulation, 40 kilometers of speed limit on the highway without road axis；30 kilometers of urban road speed limit；Same direction only has one
70 kilometers of the road speed limit of bar car lane；Same direction only has 50 kilometers of the urban road speed limit of a car lane；Vehicle
Turnover bicycle lane, level crossing, zig zag, narrow bridge and turn around, turn, lower abrupt slope speed limit be 30 kilometers；Run into rainy day, mist
My god, snowy day, sand and dust, hail, visibility be less than 50 meters when, speed limit be 30 kilometers；Fog precipitation snow sand and dust hail is run on highway
When visibility is less than 200 meters of situation, 60 kilometers of speed limit, visibility is less than 100 meters, and speed is less than 40 kilometers, and visibility is less than
50 meters, 20 kilometers of speed limit；Highway same direction has 2 tracks, and leftmost side speed is minimum 100 kilometers；On highway
Same direction has 3 tracks, and leftmost side speed is minimum 110 kilometers, middle for 90 kilometers etc..
