SURROUNDINGS RECOGNITION SYSTEM CAPABLE OF REDUCING NUMBER OF SENSORS APPLIED TO SPAS (SMART PARKING ASSISTANCE SYSTEM) AND EBA (EMERGENCY BRAKE ASSIST)

摘要

PURPOSE: A surroundings recognition system is provided to improve recognizing performance of parking area and obstacles by combining laser sensor and ultrasonic sensor.;CONSTITUTION: A surroundings recognition system comprises a front sensor unit(10), a rear sensor unit, a first control unit and a second control unit. The front sensor part senses the front obstacles. The rear sensor unit senses the rear obstacles. The first control unit searches parking area according to the forward sensing signal and the rearward sensing signal. The second control unit searches the front obstacles according to the forward sensing signal. The front sensor unit comprises a front short-range sensor(11) and a front ultra short-range sensor(12). The front short distance sensor senses the obstacles in the front center, left front and right front. The front short distance sensor senses the obstacles within the front short distance.;COPYRIGHT KIPO 2013;[Reference numerals] (11) Front short-range sensor; (20) EBA control unit; (40) SPAS control unit; (AA) Front ultra short range sensor; (BB) Rear sensor unit
