전파 및 음파를 활용한 차량의 해킹 방지 시스템의 스마트 제어 방법이 개시된다. 이 방법은 운전자의 모바일 장치로부터 블루투스 신호의 RSS 값을 수신한 뒤, 일정 강도 이상인 경우 1차 범위 내로 판단하고, 스피커를 통해 가청영역을 제외한 2~24000Hz의 음파를 송신하고, 모바일로 해당 음파를 수신하되 도달 시간(Time to arrival)을 계산하여 3D위치를 파악하는 과정을 포함하고, 미리 지정된 2차 범위 내에 들어온 경우 차량 제어 명령을 수행할 수 있는 것을 특징으로 한다. 본 발명에 따르면, 기존 스마트키의 LF(Low Frequency)를 전파 신호의 전달 방식을 음파로 대체하여 기존 차량의 스마트키 없이 모바일 장치 만으로 동일한 기능을 구현하면서 RSA를 방어할 수 있다.

    Disclosed are a method and a device for smart control of a vehicle while defending against an RSA by using a mobile device. The method comprises the steps of: establishing a communication network to be able to transmit/receive information to/from a mobile device of a driver through Bluetooth or Wi-Fi; determining, when an RSS value of a Bluetooth or Wi-Fi signal received from the mobile device of the deriver is measured to be equal to or larger than a predetermined reference value, that the position of the mobile device of the driver is within a predetermined primary range (25m) and transmitting a sound wave of 2 to 24000Hz that can be recognized through three or more speakers mounted in the vehicle; calculating the time at which the sound wave transmitted from the speakers has reached the mobile device of the driver and thereby identifying the 3D position of the mobile device of the driver; receiving a command to open/close a door or a trunk from the mobile device of the driver when the 3D position of the mobile device of the driver has approached within a predetermined secondary range (1m); and controlling the start of the vehicle when it is determined that the mobile device of the driver is positioned in a predetermined zone inside the vehicle after the door or trunk is opened. According to the present invention, the same function is applied to a door lock system such that, when the user approaches within a predetermined distance, simply holding an authenticated mobile device automatically opens the door lock.
