CAR REAR COLLISION ACCIDENT ESTIMATE AND PASSENGER PROTECTOR SYSTEM

摘要

A collision accident estimation in a rear of a car and passenger protection system, and a method thereof are provided to estimate an collision accident in the rear of the car by using a Doppler radar or an ultrasound sensor. A collision accident estimation in a rear of a car and passenger protection system includes a rear detection part(1), a controller(2), a alarm driving part(3), a safety belt fastening part(4), a head band fastening part(5), and a power supply(6). The rear detection part outputs a certain detection signal by detecting an approach and an approach speed of an object in the rear of the car in real time. The controller determines whether an alarm for a rear collision accident must go off or not by analyzing and comparing an inputted detection signal with pre-stored data and outputs a control signal corresponding to a determination. The alarm driving part drives an alarm visually and with sound by a control of the controller. The safety belt fastening part fastens an safety belt by the control of the controller. The head band fastening part fixes a head of a passenger by the control of the controller. The power supply supplies each component with a driving power.
