Description

一种通信方法及装置 技术领域
本申请涉及通信技术领域,尤其涉及一种通信方法及装置。
背景技术
随着车辆智能技术的不断发展,现在车辆上大都配置有无感车钥匙,无感车钥匙是内置在终端设备(例如手机、智能钥匙或穿戴设备)内部的数字钥匙。内置无感车钥匙的终端设备通过与车载终端无线通信连接(例如,蓝牙连接),可以实现车辆的自动解锁功能或自动闭锁功能。如图1所示,当该终端设备处于车辆的无线通信区域内时,在距离车辆的不同范围内依次点亮迎宾灯、解锁车门以及一键启动车辆(例如,启动发动机)。相应的,当该终端设备处于车辆的无线通信区域之外时,车辆自动闭锁。其中,该终端设备处于车辆的无线通信区域内与车载终端建立通信连接之后,终端设备与车载终端之间按照一个信号传输的周期收发报文。若该周期设置较短,可以降低终端设备与车载终端之间通信时延,进而提升车辆解锁或车辆闭锁的速度,但终端设备频繁收发报文会增加终端设备的功耗,使得终端设备的待机时间比较短,影响用户的使用体验。

在一种可能的设计中,第一设备可以通过车载传感器获取上述状态信息。其中,车载传感器包括但不限于超声波传感器、车载座椅的压力传感器、或车门传感器等中的至少一项。在该设计中,第一设备可以通过车载传感器获取车载零部件的状态信息,使得第一设备可以根据车载零部件的状态,确定出较为准确的用户意图。
在本申请实施例中,第一设备确定是否调整第二设备与第一设备之间信号传输的周期,包括但不限于以下实施方式:
实施方式1,第一设备根据驻车意图、下车意图、或离车意图中的任一项时,确定是否需要对第二设备与第一设备之间信号传输的周期进行调整。
在一种可能的设计中,在第一设备检测到驻车意图时,确定需要将第二设备与第一设备之间信号传输的第一周期调整为第二周期,且第一周期大于第二周期。可以理解的是,第一设备在检测到驻车意图时,意味着用户可能存在锁车的需求,因此通过将第一周期调小,可以降低第二设备与第一设备之间信号传输的通信时延,进而可以提升车辆闭锁的速度,有效满足用户的锁车需求。
在另一种可能的设计中,在第一设备检测到驻车意图时,确定需要将第二设备与第一设备之间信号传输的第一周期调整为第二周期,且第一周期小于第二周期。可以理解的是,第一设备在未检测到驻车意图时,意味着用户不存在锁车的需求,因此通过将的第一周期调大,可以降低第二设备与第一设备之间信号传输的频率,进而降低第二设备和第一设备的功耗,进而有效提升用户体验。
进一步的,第一周期被调整为第二周期之后,第一设备还可以根据下车意图确定是否需要对第二周期进行调整。
在一种可能的设计中,若第一设备在车辆处于驻车状态后的第一预设时长内,检测到下车意图,向第二设备发送第二请求信息,该第二请求信息用于将第二周期调整为第三周期,且第三周期小于第二周期。如此,通过将第二周期调小为第三周期,可以进一步降低第二设备与第一设备之间信号传输的通信时延,进而可以进一步提升车辆闭锁的速度,更加有效地满足用户的锁车需求。
在另一种可能的设计中,第一设备在车辆处于驻车状态后的第一预设时长内未检测到下车意图,向第二设备发送第三请求信息,该第三请求信息用于将第二周期调整为第四周期,第四周期大于第二周期。可以理解的是,在车辆处于驻车状态后的第一预设时长内,未检测到下车意图,意味着用户只是暂时驻车,不存在锁车的需求,因此将第二周期调大为第四周期,可以进一步降低第二设备与第一设备之间信号传输的频率,从而降低第一设备和第二设备的功耗,进一步提升用户体验。
进一步的,第二周期被调整为第三周期之后,第一设备还可以根据离车意图确定是否需要对第三周期进行调整。
在一种可能的设计中,第一设备在检测到下车意图后的第二预设时长内,检测到离车意图,向第二设备发送第四请求信息,该第四请求信息用于将第三周期调整为第五周期, 且第五周期小于第三周期。可以理解的是,第一设备在检测到下车意图后的第二预设时长内,检测到离车意图,意味着用户存在锁车需求,因此通过将第三周期调小为第五周期,可以进一步降低第二设备与第一设备之间信号传输的通信时延,进而可以进一步提升车辆闭锁的速度,从而有效提升用户的锁车体验。
在另一种可能的设计中,第一设备在检测到下车意图后的第二预设时长内,未检测到离车意图,向第二设备发送第五请求信息,该第五请求信息用于将第三周期调整为第六周期,第六周期大于第三周期。可以理解的是,第一设备在检测到下车意图后的第二预设时长内,未检测到离车意图,意味着用户只是暂时下车,不存在锁车的需求,通过将第三周期调大为第六周期,可以进一步降低第二设备与第一设备之间信号传输的频率,从而降低第一设备和第二设备的功耗,进一步提升用户体验。
实施方式2,第一设备在车辆的行驶过程中检测到驻车意图,意味着用户可能存在锁车的需求,但不对第二设备与第一设备之间信号传输的第一周期进行调整。第一设备进一步根据下车意图的检测情况,确定是否需要对第一周期进行调整。
在一种可能的设计中,第一设备在车辆处于驻车状态后的第一预设时长内,检测到下车意图,向第二设备发送第六请求信息,第六请求信息用于将第一周期调整为第三周期,该第三周期小于第一周期。可以理解的是,第一设备在车辆处于驻车状态后的第一预设时长内,检测到下车意图,意味着用户可能存在锁车的需求,因此将第二设备与第一设备之间信号传输的第一周期调小为第三周期,可以降低第二设备与第一设备之间信号传输的通信时延,进而可以提升车辆闭锁的速度,提升用户的锁车体验。
在另一种可能的设计中,第一设备在车辆处于驻车状态后的第一预设时长内未检测到下车意图,向第二设备发送第七请求信息,该第七请求信息用于将第一周期调整为第四周期,该第四周期大于第一周期。可以理解的是,第一设备在车辆处于驻车状态后的第一预设时长内,未检测到下车意图,意味着用户只是暂时驻车,不存在锁车的需求,因此将第二设备与第一设备之间信号传输的第一周期调大为第四周期,可以降低第二设备与第一设备之间信号传输的频率,从而降低第一设备和第二设备的功耗,减少第一设备和第二设备的耗电量,进而提升用户体验。
实施方式3,第一设备在车辆的行驶过程中检测到驻车意图和下车意图,意味着用户可能存在锁车的需求,但不对第二设备与第一设备之间信号传输的第一周期进行调整。第一设备进一步根据离车意图的检测情况,确定是否需要对第一周期进行调整。
在一种可能的设计中,第一设备在检测到下车意图后的第二预设时长内,检测到离车意图,向第二设备发送第八请求信息,该第八请求信息用于将第一周期调整为第五周期,第五周期小于第一周期。可以理解的是,第一设备在检测到下车意图后的第二预设时长内,检测到离车意图,意味着用户存在锁车的需求,因此将第二设备与第一设备之间信号传输的第一周期调小为第五周期,可以降低第二设备与第一设备之间信号传输的通信时延,进而可以提升车辆闭锁的速度,提升用户的锁车体验。
在另一种可能的设计中,第一设备在检测到下车意图后的第二预设时长内,未检测到离车意图,向第二设备发送第九请求信息,第九请求信息用于将第一周期调整为第六周期,第六周期大于第一周期。可以理解的是,第一设备在检测到下车意图后的第二预设时长内,未检测到离车意图,意味着用户只是暂时下车,不存在锁车的需求,进而将第二设备与第一设备之间信号传输的第一周期调大为第六周期,可以降低第二设备与第一设备之间信号 传输的频率,从而降低第一设备和第二设备的功耗,减少第一设备和第二设备的耗电量,进而提升用户体验。

在本申请实施例中,用户意图用于确定是否需要调整第二设备与第一设备之间信号传输的第一周期。其中,“第一周期”可以理解为第二设备与第一设备之间信号传输的间隔周期,因此第一周期越小,第二设备与第一设备之间信号传输的通信时延越小,但会增大第二设备和第一设备的功耗;相应的,第一周期越大,可以降低第二设备与第一设备之间信号传输的频率,进而降低第二设备和第一设备的功耗,减少第一设备和第二设备的耗电量,从而提升用户体验。
由前文描述可知,在本申请实施例中,用户意图用于表征用户对车辆的操作行为。以及,在本申请实施例中,用户意图包括但不限于驻车意图、下车意图、或离车意图中的至少一项。如此,本申请实施例中提供了多种用户意图,进而可以结合不同的用户意图,实时调整第二设备与第一设备之间信号传输的周期,平衡第二设备与第一设备之间信号传输的时延和功耗。其中,驻车意图用于表征车辆将处于驻车状态。其中,下车意图用于表征用户从位于车内将变更成位于车外;并且,“用户从位于车内将变更成位于车外”可以理解为车辆内的部分用户(例如车主)或所有用户(包括车主和乘客)下车。也就是说,车辆内的部分用户(例如车主)或所有用户(包括车主和乘客)下车,可以认为用户存在下车意图。其中,离车意图用于表征用户与车辆之间的第一距离大于预设距离,并且,“用户与车辆之间的第一距离大于预设距离”可以理解为车辆内的部分用户(例如车主)或所有用户(包括车主和乘客)与车辆之间的第一距离大于预设距离。也就是说,车辆内的部分用户(例如车主)或所有用户(包括车主和乘客)远离车辆,可以认为用户存在离车意图。例如,对于仅车主远离车辆,车主的孩子仍然在车内休息,需要锁车的场景,在检测到车主与车辆的距离大于预设距离时,则认为检测到离车意图。
由于本申请实施例中的用户意图存在多种情况,本申请实施例中,第一设备根据车载零部件的状态,确定用户意图,有多种实现方式。下面分情况进行介绍:

情况2,用户意图包括下车意图,且车载零部件包括车辆的挡位、安全带、座椅、和车门时,第一设备可以在车载零部件的状态满足第一条件时,确定当前用户意图包括下车意图;其中,第一条件包括以下至少一项:车辆中的挡位为驻车挡,车辆中的安全带处于开启状态,车辆中的座椅承受的压力值小于预设值,车辆中的车门开启后关闭。其中,“车门开启后关闭”可以理解为车辆在预设时长内开启后关闭,该预设时长例如可以为1分钟、2分钟、或3分钟中的任一项。其中,该座椅能承受的压力预设值例如可以是500N。
情况3,用户意图包括离车意图,且车载零部件的状态包括车载零部件采集的数据,车载零部件采集的数据用于表征用户与车辆之间的第一距离;相应的,第一设备在第一距 离大于预设距离时,确定当前用户意图包括离车意图。其中,车载零部件采集的数据例如可以包括超声波传感器、车载蓝牙通信模块、车载相机、车载雷达等中的至少一项采集的数据。在一种可能的实施方式中,用户随身携带第二设备,则“用户与车辆之间的第一距离”可以通过第二设备与车辆之间的距离来确定。示例性的,预设距离例如可以5m、4m、或3m中的任一项。
S303:第一设备在确定调整第一周期时,向第二设备发送第一请求信息,该第一请求信息用于将第一周期调整为第二周期。相应的,第二设备接收第一请求信息。
在一种可能的实施方式中,第一设备可以与第二设备建立蓝牙通信连接,进而第一设备可以通过该蓝牙通信连接向第二设备发送第一请求信息。在另一种可能的实施方式中,第一设备可以与第二设备建立UWB通信连接,进而第一设备可以通过该UWB通信连接向第二设备发送第一请求信息。
S304:第二设备响应于第一请求信息,将第一周期调整为第二周期。
在一种可能的实施方式中,第二设备中设置有与车辆中的电子锁系统相适配的数字钥匙系统,数字钥匙系统用于控制车辆的零部件状态;其中,数字钥匙系统包括无线通信模块,第一周期为无线通信模块与第一设备之间信号传输的周期。车辆的零部件状态包括车门、车窗、或车灯、发动机中至少一项的状态。如此,第二设备与第一设备之间信号传输的第一周期即为数字钥匙系统中的无线通信模块与第一设备之间信号传输的周期。并且,可以结合用户意图,动态调整第一周期,实现第二设备与第一设备之间信号传输的功耗和通信时延的平衡,从而提升用户体验。例如,将第一周期调小,则第二设备与第一设备之间信号传输的通信时延越小,车辆解锁或闭锁的速度越快,从而满足用户的解锁或闭锁需求;又例如,在用户不存在解锁或闭锁需求时,将第一周期调大,可以降低第二设备与第一设备之间信号传输的频率,进而降低第二设备和第一设备的功耗,减少第一设备和第二设备的耗电量,从而提升用户体验。可以理解的是,本申请实施例中,车辆闭锁或解锁涉及的车载零部件包括但不限于车门、车窗、发动机或车灯中至少一项,相应的,数字钥匙系统在用于控制车辆闭锁或解锁时,可以控制这些车载零部件的状态。
