Abstract :
A traffic accident is an incident where a motorized vehicle collides with another
object that causes material damage and loss. The purpose of this research is to
design an automatic braking system that is able to give a warning with an alarm
and stop the vehicle's speed so that the vehicle's speed will be stopped before a
collision occurs. In its design the MB1010 LV-MaxSonar-EZ1 Sonar Range
Finder sensor will detect objects or obstructions in front, the system will alert
buzzer sound and turn on the LED lights. The sensor detects a distance of 645.16
cm, the green LED is active / lit while the yellow and red LEDs are inactive as
well as the buzzer. The sensor detects a distance of 96.62 cm, green LEDs and
yellow LED are inactive. While the red LED and buzzer are active which indicate
the distance is not safe as well as an active relay and turn off the speed of the
motorcycle. The sensor detects a distance of 144.74 cm, the state of the green
LED and the yellow LED is off. While the red LED and buzzer are active which
indicate the distance is not safe as well as an active relay and turn off the speed of
the motorcycle.
