Description
Technical field
The present invention relates to a kind of intelligent transportation equipment, more particularly to one kind can perceive speed and liftable deceleration strip.
Background technology
The design original intention of deceleration strip is that, for speed limit, when vehicle high-speed passes through deceleration strip, deceleration strip will be produced to vehicle
The larger resistance of life, and produce compared with pitchpole, so as to reach reduction of speed purpose；But, when car speed low speed passes through, deceleration strip
Can still cause jolting for vehicle, and can cause the sport car cannot safety deceleration strip；It will be apparent that when vehicle low speed passes through
When, existing deceleration strip does not play a role not only, and may scratch to the relatively low vehicle in chassis.
The content of the invention
The drawbacks of to solve existing deceleration strip, automatic lifting can be carried out according to speed it is an object of the invention to provide a kind of
