Smart key system implemented using by three antennas and vehicle control method in control unit of the system

摘要

A smart key system implemented with three antennas is disclosed. The smart key system includes a first antenna disposed at the front and rear center of the inner loop of the vehicle, and a third antenna disposed so as to partially overlap a communication area between the second antenna and the second antenna, And a Smart Key is transmitted to the vehicle interior area or the vehicle outdoor area through the received signal strength indication (RSSI) value between the smart key, the first antenna, and the antenna of either the second antenna or the third antenna. Control unit is included to determine if there is. As a result, it is possible to reduce the number of wires between the electronic control unit (ECU) and the antenna to three sets from six sets, thereby providing a cost reduction.;
