The invention provides a Bluetooth signal identification method and a Bluetooth signal identification system. If a Bluetooth transmitting module is located in an area in a vehicle, a first signal value obtained by a Bluetooth measurement unit outside the vehicle is within a first threshold range; at the moment, whether a second signal value obtained by an in-vehicle Bluetooth measurement unit is larger than the sum of a second threshold value and a first preset value or not is judged, that is to say, a boundary strength threshold value is broadened, so that the influence of in-vehicle interference on the second signal value obtained by the in-vehicle Bluetooth measurement unit is reduced, and the accuracy of Bluetooth signal recognition and judgment is improved; if the Bluetooth transmitting module is located in an area outside the vehicle close to the vehicle, the first signal value obtained by the Bluetooth measurement unit outside the vehicle is not within the first threshold range,and whether the second signal value obtained by the Bluetooth measurement unit inside the vehicle is larger than the second threshold or not is judged, that is, the boundary strength threshold is reduced to the normal value equivalently, so that misjudgment of the position of the Bluetooth transmitting module outside the vehicle is avoided.

    本发明提供一种蓝牙信号识别方法与蓝牙信号识别系统,如蓝牙发射模块处于车辆内区域,车外蓝牙测量单元所获得的第一信号值在第一阈值范围内,此时判断车内蓝牙测量单元所获得的第二信号值是否大于第二阈值与第一预定值之和,即相当于将边界强度阈值放宽,以减小车内干扰对于车内蓝牙测量单元所获得的第二信号值的影响,提高蓝牙信号识别和判断的准确度;如蓝牙发射模块处于车辆外靠近车辆的区域,则车外蓝牙测量单元所获得的第一信号值不在第一阈值范围内,此时判断车内蓝牙测量单元所获得的第二信号值是否大于第二阈值,即相当于将边界强度阈值缩减回正常值,避免在车外对蓝牙发射模块的位置产生误判。
