The invention provides an intelligent unlocking and starting method for a vehicle, which is suitable for the situation that an intelligent terminal is used as a vehicle key, and comprises the following steps of: setting a maximum value of a relative position of the intelligent terminal and the vehicle as an intelligent unlocking threshold value; judging whether satellite positioning is accurate by the vehicle and the intelligent terminal; when satellite positioning is accurate, calculating the relative position of the intelligent terminal and the vehicle by a vehicle body control unit of the vehicle according to the position coordinates; when satellite positioning is inaccurate, the vehicle sends out a Bluetooth field intensity signal, the intelligent terminal receives and feeds back the Bluetooth field intensity signal to the vehicle body control unit, and the vehicle body control unit calculates the relative position of the intelligent terminal and the vehicle according to the feedback Bluetooth field intensity signal; comparing the relative position with an intelligent unlocking threshold value; and when the relative position is not larger than the intelligent unlocking threshold value, automatically unlocking the vehicle. According to the method, accurate positioning of the intelligent terminal serving as a vehicle key under various application scenes can be achieved, and intelligent unlocking can be achieved through sensitive induction under the condition that satellite positioning is inaccurate or weak.

    本发明提供了一种车辆智能开锁及启动方法,适用于智能终端作为车辆钥匙的情形,包括以下步骤,设定一智能终端与车辆相对位置最大值作为智能开锁阈值;车辆与智能终端判断卫星定位是否准确;当卫星定位准确时,车辆的车身控制单元根据位置坐标计算智能终端与车辆的相对位置;当卫星定位不准确时,车辆发出蓝牙场强信号,智能终端接收并反馈给车身控制单元,车身控制单元根据反馈的蓝牙场强信号计算智能终端与车辆的相对位置;比较相对位置与智能开锁阈值的大小;当相对位置不大于智能开锁阈值时,车辆自动解锁。通过上述技术方案,可以实现各种应用场景下智能终端作为车辆钥匙的精准定位,在卫星定位不准或较弱的情况下也可以灵敏感应实现智能开锁。
