1211 control instructions lamps 15 can issue white light；When the braking acceleration of vehicle is increased to greater than first threshold and less than the second threshold
Value, that is, when reaching heavy brake state, the meeting horse back control instructions lamp 15 of main control module 1211 is changed to sending blue light；When the braking of vehicle adds
Speed is increased to again greater than second threshold, that is, when reaching emergency brake state, 1211 horse back control instructions lamp 15 of main control module is changed to hair
Yellow light and stroboscopic out.But when the braking acceleration of vehicle at the beginning is greater than second threshold, belong to emergency brake state, main control module
1211 control instructions lamps 15 issue yellow light and stroboscopic, even if the braking acceleration of vehicle is prominent within the time of 15 Yellow light-emitting low temperature of indicator light
It is so decreased to less than second threshold, the luminance that main control module 1211 continues control instructions lamp 15 does not change, until meter
When module 123 fluorescent lifetime of indicator light 15 is recorded terminates and generate feedback signal transmission to main control module 1211, master control mould
Feedback signal switches to the sending white light of control instructions lamp 15 or blue light to block 1211 again based on the received.It is further appreciated that the meter
When module 123 be timing circuit.It is appreciated that main control module 1211 can be with during the braking acceleration of vehicle increases
The luminance of control instructions lamp 15 is mutated, and wherein luminance mutation refers to issuing a kind of hair of color of light in indicator light 15
Light time interior horse back switches to another color of light of hair；And during the braking acceleration of vehicle reduces, main control module
The luminance of 1211 control instructions lamps 15 does not mutate, i.e., indicator light 15 in the fluorescent lifetime for issuing a kind of color of light not
The light for sending out another color can be switched at once, such as vehicle is in emergency brake state at the beginning, indicator light 15 can issue yellow light and
Stroboscopic, fluorescent lifetime 5s, the braking acceleration of vehicle reduces within the time of 5s, and the braking state of vehicle becomes heavy brake or light
It stops, indicator light 15, which is also to maintain, at this time issues yellow light and stroboscopic, until the time 5s of Yellow light-emitting low temperature terminates, indicator light 15 can just switch
At blue light-emitting or white light, to realize the reverse media function of 15 luminance of indicator light.
Since braking acceleration is jumpy, the brake warning lamp meeting of usual vehicle itself to vehicle in braking process
Light, but can not accurately show the deceleration situations of current vehicle, front vehicle be also unable to judge accurately front vehicles be emergency brake,
Heavy brake or light brake.The rear-end device 10 of the utility model can issue different colors according to the braking state of vehicle
Light, so as to remind front vehicle well judge front vehicles be emergency brake, it is light stop or heavy brake, prevent to knock into the back,
And the rear-end device 10 of the utility model have reversed cutoff function, i.e., indicator light 15 light variation can only from gently stop to
Emergency brake mutation, and cannot from emergency brake to light mutation of stopping, the pilot light of the emergency brakes such as only can be just then turned on after terminating it is light stop or
The pilot light of heavy brake further helps in the generation for preventing rear-end collision.
In addition, the circuit board 12 further includes multiple operational modules, specially the first operational module 126, the second Working mould
