图3是根据本申请又一个实施例的差速锁的控制方法的流程图。
具体实施方式
下面详细描述本申请的实施例，所述实施例的示例在附图中示出，其中自始至终相同或类似的标号表示相同或类似的元件或具有相同或类似功能的元件。下面通过参考附图描述的实施例是示例性的，旨在用于解释本申请，而不能理解为对本申请的限制。
下面参考图1-图3描述根据本申请实施例的用于车辆的差速锁的控制方法。
根据本申请的差速锁的控制方法包括：当车辆接收到前驱动桥锁止信号时，获取车辆的当前车速并检测车辆的驱动模式是否处于四驱模式；若车辆的当前车速不大于预设车速且处于四驱模式；则控制车辆的前驱动桥锁止或前驱动桥与后驱动桥同时锁止。
相关技术中，车辆的前驱动桥为转向桥，当前驱动桥的左右半轴刚性连接时，左右车轮转速一致，会使转弯半径过大，导致车辆转向不足，为了保证驾驶安全，前驱动桥差速器锁仅允许在极限越野路况时才能激活，即当四驱模式和后驱动桥锁止都不足以使车辆脱困的情况下，才允许激活前驱动桥差速锁。前驱动桥差速锁开启条件是：车辆处于四驱模式且后驱动桥锁止，车速小于预设车速时，才能实现前驱动桥差速锁激活，此策略的缺点是前驱动桥差速器锁止的方法仅有单一的固定顺序，如遇到紧急情况时，由于繁琐的操作，容易出现越野驾驶危险。
根据本申请的用于车辆的差速锁的控制方法，在车辆接收到前驱动桥的锁止信号时，检测车辆的当前车速和车辆的驱动模式，在车辆处于四驱模式下，若车辆接收到前驱动桥锁止信号则控制车辆的前驱动桥锁止或控制前驱动桥与后驱动桥同时锁止。
现有技术方案中，对于前驱动桥的锁止必须是在严苛的条件下才能够激活前驱动桥的锁止，只有在车辆处于四驱模式，且后驱动桥已经锁止并且车速保持在预设车速以下，车辆才会将前驱动桥锁止，这种前驱动桥的锁止方法无法快速响应用户的需求。
当车辆已经处于四驱模式，但需要紧急脱困时，现有的差速锁的控制方法无法满足车辆的动力需求，而本申请仅需要考虑到车辆的当前车速和车辆的驱动模式是否满足要求，通过控制前驱动桥和后驱动桥的锁止，使车辆能够及时响应用户的需求，特别是在车辆在后驱动桥未锁止的情况下，仍然能够使车辆在接收前驱动桥的锁止信号时，控制前驱动桥与后驱动桥同时锁止。
根据本申请的用于车辆的差速锁的控制方法，仅需要考虑车辆的当前车速和车辆当前的驱动模式，无需进一步考虑车辆的后驱动桥是否已锁止，减少了车辆实现前驱动桥锁止的步骤，使车辆的前驱动桥的锁止响应更加迅速，简化了前驱动桥差速锁锁止的步骤。
根据本申请的一个实施例，若车辆接收到前驱动桥锁止信号、车辆的当前车速不大于预设车速且驱动模式处于四驱模式；则向车辆输出前驱动桥锁止确认信号。
这里需要说明的是，前驱动桥锁止信号是在用户通过操控前驱动桥锁止按钮以向车辆的车身控制器发送前驱动桥锁止信号，车身控制器将前驱动桥锁止信号通过CAN总线发送给车辆的前驱动桥差速锁。
前驱动桥差速锁接收到前驱动桥锁止信号后结合四驱控制单元所确认的车辆的驱动模式、车速和后桥差速锁的状态信息，判断后发送前驱动桥锁止确认信号或拒绝前驱动桥锁止信号到CAN总线，CAN总线发送前、后差速锁确认信号给开关和仪表用于显示或提醒用户。
根据本申请的一个实施例，若车辆接收到前驱动桥锁止确认信号则控制车辆的指示灯常亮。这里的指示灯可以是车辆仪表中的指示灯以用于反应车辆的前驱动桥的差速锁已经激活。
根据本申请的一个实施例，若车辆的当前车速大于预设车速，则在车辆的当前车速小于所述预设车速时控制车辆的前驱动桥锁止或前驱动桥与后驱动桥同时锁止。
为了保证车辆能够及时将前驱动桥的差速锁锁止，确保车辆的前驱动桥能够及时响应用户的需求，在车辆的当前车速大于预设车速时，车辆无法将前驱动桥锁止，以用于保护车辆的前驱动桥，避免在车辆的车速过快的情况下将车辆的前驱动桥锁止。
在车辆的车速满足车辆的前驱动桥的差速锁和后驱动桥的差速锁的锁止条件后，将车辆的前驱动桥的差速锁或后驱动桥的差速锁进行锁止，可以避免车辆在车速过高的情况下将车辆中的前驱动桥的差速锁或后驱动桥的差速锁锁止，提高对于车辆中驱动桥差速锁控制的安全性。在车辆满足前驱动桥锁止的条件后，及时将车辆的前驱动桥锁止，以使车辆的脱困能力能够及时满足用户的需求，提高了车辆的安全性。
根据本申请的一个实施例，若车辆的当前车速大于预设车速且车辆的后驱动桥锁止，则向车辆反馈前驱动桥待锁止信号，前驱动桥差速锁接收到前驱动桥锁止信号后结合电控四驱控制单元所确认的车辆的驱动模式、车速和后桥差速锁的状态信息，若车辆的当前车速大于预设车速、车辆的后驱动桥锁止，则向车辆反馈前驱动桥待锁止信号，并通过CAN总线发送前驱动桥待锁止信号给开关和仪表用于提醒用户。
车辆接收到前驱动桥锁待锁止信号则控制车辆的指示灯闪烁，在车辆的指示灯闪烁的过程中，可以提醒用户当前车速过高，不满足前驱动桥差速锁的锁止条件，以提醒用户降低车速进行前驱动桥差速锁的激活。也可以用于反馈车辆的当前状态信息，使用户能够了解车辆的当前状态，避免用户重复按动按键。
根据本申请的一个实施例，若车辆的当前车速大于预设车速且后驱动桥解锁，则在当前车速低于预设车速后控制所述后驱动桥和前驱动桥同时锁止。为确保车辆行驶的安全性，若车辆的车速大于预设车速，则车辆的前、后驱动桥均无法锁止，只有在车辆的 当前车速低于预设车速时，才能使车辆的前驱动桥的差速锁和后驱动桥的差速锁激活，在前驱动桥的差速锁的激活过程中，减少了车辆对后驱动桥的锁止过程，简化了车辆的差速锁的操作步骤，使车辆的操作更加方便。
在本申请的一个实施例中，若车辆的当前车速大于预设车速，则向车辆反馈前驱动桥待锁止信号和后驱动桥待锁止信号。在车辆接收到前驱动桥待锁止信号和后驱动桥待锁止信号后，控制车辆中的前驱动桥锁止指示灯和后驱动桥的锁止指示灯闪烁，以用于提醒用户。
在车辆的当前车速小于预设车速后控制后驱动桥和前驱动桥同时锁止，以使车辆能够及时响应用户的需求，使车辆在四驱模式下，只要接收到前驱动桥锁止信号，就可以在车速低于预设车速后控制车辆的前驱动桥和后驱动桥同时锁止，使车辆能够获得最佳脱困能力。
在本申请的一个实施例中，车辆的预设车速为5km\h，在预设车速下，车辆能够安全地进行前驱动桥差速锁的锁止和后驱动桥的差速锁的锁止。
下面简单描述根据本申请的用于车辆的差速锁的控制装置。
根据本申请的用于车辆的差速锁的控制装置包括：接收模块、检测模块和控制模块，接收模块用于接收驱动桥锁止信号，检测模块用于检测车辆的当前车速以及车辆当前的驱动模式，控制模块用于根据上述实施例中任意一项所述的差速锁的控制方法以及车辆的当前车速和驱动模式控制前驱动桥和/或后驱动桥的锁止。
根据本申请的用于车辆的差速锁的控制装置，能够根据车辆的当前驱动模式、车辆的速度及时控制车辆的差速锁锁止，车辆的前驱动桥的锁止响应速度快，可靠性好。
下面简单描述根据本申请的车辆。
根据本申请的车辆上设置有上述实施例的用于车辆的差速锁的控制装置，由于根据本申请的车辆上设置有上述实施例的用于差速锁的控制装置，因此该车辆的脱困性能好，前驱动桥可以及时响应用户的需求进行锁止，响应速度快，可靠性高。
尽管上面已经示出和描述了本申请的实施例，可以理解的是，上述实施例是示例性的，不能理解为对本申请的限制，本领域的普通技术人员在本申请的范围内可以对上述实施例进行变化、修改、替换和变型。
