Overview

Back Parking Aid System
BPAS is an abbreviation of back parking aid system. When a car is moving in reverse, the ultrasonic sensor sends an information to ECU (Electronic Control Unit) detecting object of behind the vehicle. Then ECU calculates the distance from vehicle to object, and warns driver with a specific warning sound, if car approaches too close to an object. If the distance to the object is in any warning zone, BPAS warns driver with specific warning sound & LED color.

Currently first BPAS starts on the Export Europe market sales, and after this it is planning to domestic, to export USA, Asia, etc.
