VEHICLE BRAKING INDICATOR Russian patent published in 2007 - IPC B60Q1/44 

FIELD: transport engineering; braking indicators.

SUBSTANCE: proposed device has pulser 9, housing and braking indicator 8 of vehicle. Device includes additionally shaper 1, one-shot multivibrator 2, low-pass filter 3, derivative discriminating circuit 4, reference voltage divider 6, reference voltage source 5 and comparator strip 7. Output of pulser 9 is connected with input of shaper 1 whose output is coupled with input of one-shot multivibrator 2. Output of one-shot multivibrator 2 is connected with input of low-pass filter 3 whose output is connected to derivative discriminating circuit 4, output of which is connected to first input of comparator strip 7. Other inputs of comparator strip 7 are connected with outputs of reverence voltage divider 6 whose input is coupled with output of reference voltage source 5. Outputs of comparator strip 7 are coupled with inputs of braking level indicator 8.

EFFECT: improved reliability and information content of device.
