Motorcycle Deceleration Indicator

Published:2011/7/10 5:34:00 Author:Sue | Keyword: Motorcycle, Deceleration, Indicator | From:SeekIC

When the motorcycle has a constant speed, the deceleration automatic switch S1 is disconnected and IC's pin Z and pin 4 both have high level. HL is not illuminated. When the motorcycle is slowing down, according to the mechanics principle, the motorcycle will have a negative acceleration, which will make S1's inner moving contact have a forward driving force. Then the moving contact and the fixed contact will be connected and IC's pin Z and pin 4 will have low level and HL is illuminated. C is the time-delay capacitor. When S1's moving contact and fixed contact are disconnected, C is charged through R2. When C's voltage reaches 1.6v, IC's pin 4 becomes high level. Then the occasion that the brake lamp HL will not twinkle when the motorcycle is running on an uneven road will be avoided.
