相对于现有技术,本申请所述的一种控制涉水模式差速锁的方法具有以下优势:
本申请所述的控制涉水模式差速锁的方法,在高速涉水模式只锁止中央差速锁,而不联动锁止后桥差速锁,以此避免因后桥差速锁锁止后,导致的在涉水模式下高速四驱行驶过程中的侧滑问题发生;在低速涉水模式下只锁止中央差速锁和后桥差速锁,而不联动锁止前桥差速锁,以此避免涉水模式下低速行驶过程中,因前桥差速锁锁止后造成的车辆转向受限,进而导致车辆转向未达到驾驶员所需的转向时,发生不可预知风险的可能性增加的问题。
本申请所述的控制涉水模式差速锁的方法,锁止后的差速锁,在未进一步接收到用户的解锁指令时,锁止后的差速锁将处于一直锁止的状态。以避免涉水模式下,差速锁在达到解锁速度时进行解锁,而此时车辆处于打滑状态,车辆的实际速度并未达到车辆显示的车速,由此导致的车辆脱困能力降低的问题。
同时,本申请所述的控制涉水模式差速锁的方法,在低速涉水模式下, 在接收到对应的控制请求后,只有在满足车辆处于设定的状态时,中央差速锁和后桥差速锁才会进行锁止,此时车辆进入低速涉水模式。避免了车辆在不满足进入低速涉水模式的工况下,进入到低速涉水模式而使得车辆发生不可预知风险的可能性增加的问题。

详细描述
需要说明的是,在不冲突的情况下,本申请中的实施例及实施例中的特征可以相互组合。
下面将参考附图并结合实施例来详细说明本申请。
图1是本申请一实施例示出的控制涉水模式差速锁的方法的流程图。参照图1,本申请提供的控制涉水模式差速锁的方法包括以下步骤:
步骤S11:接收到控制请求。
在本实施例中,用户通过触发操作,控制车身稳定控制系统ESP发出控制请求,车内的电子差速锁接收到该控制请求。
步骤S12:根据所述控制请求,确定车辆的当前状态。
在本实施例中,电子差速锁接收到该控制请求后,需要确定车辆的当前状态,根据车辆的当前状态,确定处于当前状态的车辆是否满足切换到该控制请求对应的涉水模式。
步骤S13:在所述车辆的当前状态处于预设状态时,响应于所述控制请求,控制中央差速锁和后桥差速锁中的至少一者锁止,以控制所述车辆处于对应于所述控制请求的涉水模式。
在本实施例中,在确定车辆的当前状态处于满足切换到该控制请求对应 的涉水模式的预设状态时,车辆中的电子差速锁响应于该控制请求,进行锁止操作,完成锁止操作的电子差速锁控制车辆进入对应于该控制请求的涉水模式。
在本申请中,所述在所述车辆的当前状态处于预设状态时,响应于所述控制请求,控制中央差速锁和后桥差速锁中的至少一者锁止,以控制所述车辆处于对应于所述控制请求的涉水模式,包括:在所述控制请求为高速涉水控制请求时,响应于所述高速涉水控制请求,控制所述中央差速锁进行锁止,以控制所述车辆处于对应于所述高速涉水控制请求的高速涉水模式;在所述控制请求为低速涉水控制请求,确定到所述车辆的当前状态处于预设状态时,响应于所述低速涉水控制请求,控制所述中央差速锁和所述后桥差速锁进行锁止,以控制所述车辆处于对应于所述低速涉水控制请求的低速涉水模式。
在本实施例中,在电子差速锁接收到的控制请求为高速涉水控制请求时,无需确定车辆的当前状态是否处于预设状态,电子差速锁响应于该高速涉水控制请求,电子差速锁中的中央差速锁进行锁止,而不联动锁止后桥差速锁,中央差速锁锁止后,控制车辆进入对应于该高速涉水控制请求的高速涉水模式。处于高速涉水模式的车辆可在涉水环境下进行高速四驱驱动,而不易发生侧滑,由此避免了车辆在涉水环境下,高速行进过程中因后桥差速锁锁止后,车辆后两轮处于同步转动导致的侧滑问题。
在电子差速锁接收到的控制请求为低速涉水控制请求时,需要确定车辆前状态是否处于预设状态。在电子差速锁接收到低速涉水控制请求后,在确定车辆当前状态处于满足切换到低速涉水模式的预设状态时,电子差速锁响应于该低速涉水控制请求,电子差速锁中的中央差速锁和后桥差速锁进行联动锁止,中央差速锁和后桥差速锁联动锁止后,控制车辆进入对应于该低速涉水控制请求的低速涉水模式。处于低速涉水模式的车辆可在涉水环境下进行低速四驱驱动,车辆转向不再受限,车辆发生不可预知风险的可能性降低。
本申请的控制涉水模式差速锁的方法,需要在车辆的当前状态处于满足切换到低速涉水模式下的预设状态时,车辆才能根据控制指令切换到低速涉水模式,避免了车辆在不满足进入低速涉水模式的工况下,进入到低速涉水模式而使得车辆发生不可预知风险的可能性增加的问题。
在本申请中,在控制中央差速锁和后桥差速锁中的至少一者锁止之后,还包括:控制所述至少一者锁止的差速锁保持锁止状态,直至接收到下一次 的控制请求。
在本实施例中,车辆在各种涉水模式下极易发生打滑,在车辆打滑过程中,车辆的实际车速并未达到车辆显示的车速,此时车辆的显示车速达到电子差速锁的解锁车速后完成解锁操作,同时,解锁后的差速锁将不会再上锁。因此在车辆实际处于打滑状态,车辆的实际车速并未达到电子差速锁的解锁车速,而电子差速锁却自动解锁,由此将造成车辆在涉水环境下的车辆打滑状态下的脱困能力降低。而本申请在车辆根据控制请求,控制车辆中的电子差速锁锁止后,控制锁止的电子差速锁一直保持为锁止状态,直至驾驶员按下解锁开关,或车身稳定系统发出退出当前涉水模式的解锁控制指令后,当前锁止的电子差速锁根据接收到的该解锁控制指令执行解锁操作。由此增强了车辆在涉水环境下的车辆打滑状态下的脱困能力。
在本申请中,所述车辆的当前状态处于预设状态,包括:所述车辆的车速低于预设速度、所述车辆的后左右轮转速差高于预设速度差,以及所述车辆的转向辅助系统处于关闭状态。
在本实施例中,车辆的预设状态仅针对于低速涉水模式。车辆的车速低于预设速度是为了确定车辆是否处于低速行驶过程中,车辆的后左右轮转速差高于预设速度差是为了确定车辆是否处于打滑状态,是否需要更强的脱困能力,车辆的转向辅助系统处于关闭状态是为了防止车辆在脱困的瞬间车辆发生突然转向导致侧翻。在车辆同时满足车辆的车速低于预设速度、车辆的后左右轮转速差高于预设速度差,以及车辆的转向辅助系统处于关闭状态时,确定车辆的当前状态处于满足切换到低速涉水模式的预设状态。在确定车辆的当前状态处于预设状态后,车辆的电子差速锁响应于接收到的低速涉水控制请求,电子差速锁中的中央差速锁和后桥差速锁进行锁止,中央差速锁和后桥差速锁进行锁止后,控制车辆进入低速涉水模式。
在本实施例中,图2是本申请一实施例示出的控制涉水模式差速锁的方法的电控差速锁控制策略图;图3是本申请一实施例示出的控制涉水模式差速锁的方法中的低速涉水控制请求的示意图。参照图2和图3,用户通过开关控制车身稳定控制系统ESP发出对应于高速涉水模式的高速涉水控制请求Wade_4H和对应于低速涉水模式的低速涉水控制请求Wade_4L,电子差速锁ELD响应于车身稳定控制系统ESP发出的控制请求。在车身稳定控制系统ESP发出的控制请求为对应于高速涉水模式的高速涉水控制请求Wade_4H时,电 子差速锁ELD中的中央差速锁响应于该高速涉水模式的Wade_4H,进行锁止,中央差速锁锁止后,控制车辆进入高速涉水模式。在车身稳定控制系统ESP发出的控制请求为对应于低速涉水模式的低速涉水控制请求Wade_4L时,在确定车辆的当前状态处于预设状态后,电子差速锁ELD中的中央差速锁和后桥差速锁响应于该低速涉水模式的Wade_4L,进行锁止,中央差速锁和后桥差速锁锁止后,控制车辆进入低速涉水模式。低速涉水控制请求Wade_4L的信号为DrivingModeReq_ESP,信号值为0x1。
综上所述,本申请实施例所述的控制涉水模式差速锁的方法至少包括以下优点:
本申请所述的控制涉水模式差速锁的方法,在高速涉水模式只锁止中央差速锁,而不联动锁止后桥差速锁,以此避免因后桥差速锁锁止后,涉水模式下高速四驱行驶过程中的侧滑问题发生;在低速涉水模式下只锁止中央差速锁和后桥差速锁,而不联动锁止前桥差速锁,以此降低涉水模式下,因前桥差速锁锁止后造成的车辆转向受限,发生不可预知风险的可能性。
本申请所述的控制涉水模式差速锁的方法,锁止后的差速锁,在未进一步接收到用户的解锁指令时,锁止后的差速锁将处于一直锁止的状态。以避免涉水模式下,差速锁在达到差速锁的解锁速度时进行解锁,而此时可能车辆处于打滑状态,车辆实际速度并未达到车辆显示的车速,导致的车辆脱困能力降低的问题。
同时,本申请所述的控制涉水模式差速锁的方法,在低速涉水模式下,只有在满足车辆处于设定的状态时,才会根据控制请求控制车辆进入低速涉水模式。避免了车辆在不满足进入低速涉水模式的工况下,进入到低速涉水模式而使得车辆发生不可预知风险的可能性增加的问题。
本申请实施例还提供了一种控制涉水模式差速锁的系统。图4是本申请一实施例示出的一种控制涉水模式差速锁的系统的示意图。参照图4,本申请提供的控制涉水模式差速锁的系统400包括:
请求接收模块401,用于接收到控制请求;
确定模块402,用于根据所述控制请求,确定车辆的当前状态;
