The invention provides a method and device for determining the unlocking distance of a vehicle, and the method comprises the steps: judging whether a vehicle key is a binding key of the vehicle or not when the vehicle is in a locked state and a first radio signal sent by the vehicle key is received; if the vehicle key is the binding key of the vehicle, calculating a first distance between the vehicle key and the vehicle; when a second radio signal sent by the vehicle key is received, calculating a second distance between the vehicle key and the vehicle; calculating a difference between the second distance and the first distance, and calculating a time difference between a transmission time of the second radio signal and a transmission time of the first radio signal; the moving speed of the vehicle key is obtained according to the ratio of the difference value to the time difference; and determining the unlocking distance of the vehicle at the moment based on the moving speed and the configuration information of the vehicle. The unlocking distance of the vehicle is dynamically adjusted according to the moving speed of the vehicle key, different getting-on requirements of users are met, and the user experience feeling is improved.
本发明提供一种车辆解锁距离的确定方法及装置,当车辆处于闭锁状态,且接收到车辆钥匙发送的第一无线电信号时,判断该车辆钥匙是否是车辆的绑定钥匙;若该车辆钥匙是车辆的绑定钥匙,则计算车辆钥匙与车辆之间的第一距离;当接收到该车辆钥匙发送的第二无线电信号时,计算车辆钥匙与车辆之间的第二距离;计算第二距离与第一距离之间的差值,以及计算第二无线电信号的发射时间,与第一无线电信号的发射时间之间的时间差;根据差值和时间差之间的比值,得到车辆钥匙的移动速度;基于移动速度和车辆的配置信息,确定此时车辆的解锁距离。根据车辆钥匙的移动速度动态调整车辆的解锁距离,适应用户不同的上车需求,提高了用户体验感。
