The invention relates to a positioning judgment system and method for an intelligent key under the condition of mobile phone interference. The positioning judgment system is composed of the intelligent key, a remote control receiver, a vehicle body controller and an antenna. The positioning judgment method comprises: carrying out space field interference detection, judging that the intelligent key is outside the trunk, sending field intensity values of the four antennas to the vehicle body controller by the intelligent key, and judging whether the trunk is normally closed by the vehicle body controller. The positioning judgment system of the intelligent key under the condition of mobile phone interference is simple in structure, the positioning judgment method detects mobile phone interference through the intelligent key, when space field interference is detected, it is judged that the intelligent key is located outside the luggage case, the small field intensity value of the indoor antenna/the left antenna/the right antenna is fed back, and at the moment, the vehicle body controller judges that the key is outside the vehicle, and false triggering of the trunk anti-false lock is avoided; and, under the condition of mobile phone interference, the positioning accuracy of the intelligent key can be improved, and the satisfaction degree of a user in the aspect of perception can be obviously improved.

    本发明涉及一种智能钥匙在手机干扰情况下的定位判断系统及方法,定位判断系统由智能钥匙、遥控接收器、车身控制器以及天线构成;定位判断方法,包括空间场干扰检测,智能钥匙在行李箱外部判断,智能钥匙将4根天线的场强值发送给车身控制器,车身控制器是否正常关闭行李箱。本发明智能钥匙在手机干扰情况下的定位判断系统结构简单,定位判断方法通过智能钥匙对手机干扰检测,当检测到有空间场干扰时,且判断智能钥匙处于行李箱外部,反馈室内天线/左侧天线/右侧天线较小的场强值,此时车身控制器会判断钥匙在车外,不会引起行李箱防误锁误触发;能提高在手机干扰的情况下,智能钥匙的定位准确性,可明显提升用户在感知方面的满意度。
