通过上述附图,已示出本申请明确的实施例,后文中将有更详细的描述。这些附图和文字描述并不是为了通过任何方式限制本申请构思的范围,而是通过参考特定实施例为本领域技术人员说明本申请的概念。
具体实施方式
这里将详细地对示例性实施例进行说明,其示例表示在附图中。下面的描述涉及附图时,除非另有表示,不同附图中的相同数字表示相同或相似的要素。以下示例性实施例中所描述的实施方式并不代表与本申请相一致的所有实施方式。相反,它们仅是与如所附权利要求书中所详述的、本申请的一些方面相一致的装置和方法的例子。
图1为本申请实施例提供的现有技术中车门控制方法的模块示意图,如图1所示,目前,在车辆发生碰撞后,碰撞控制器接收到碰撞信号,并将碰撞信号通过车辆中央控制器发送至车辆门控制器,以使车辆门控制器向车门解锁控制单元发送解锁指令,控制车门解锁,当车门解锁后,反馈解锁状态,由此车辆门控制器停止向车门解锁控制单元发送解锁指令。但由于车辆在发生碰撞后,车辆上各个器件的可靠性可能降低,车门解锁控制单元在使用时可能出现误触发解锁状态的可能性,使得车门在并未解锁的状态下反馈解锁状态,降低了车门解锁的可靠性。
为了解决上述问题,本申请实施例提供一种车门控制方法、装置、电子设备、车辆及可读存储介质,可以通过在接收车辆碰撞信号时,向车门解锁控制单元发送多次驱动解锁指令,并保证在发送一定次数的指令后,再确定车门的当前状态,并根据当前状态,确定是否继续发送解锁指令,从而提高车门解锁的可靠性。
下面以具体地实施例对本申请的技术方案以及本申请的技术方案如何解决上述技术问题进行详细说明。下面这几个具体的实施例可以相互结合,对于相同或相似的概念或过程可能在某些实施例中不再赘述。下面将结合附图,对本申请的实施例进行描述。
本申请实施例提供的车门控制方法的执行主体可以是服务器。其中,服务器可以为车载电脑等设备。本实施例对执行主体的实现方式不做特别限制,只要该执行主体能够在接收到车辆碰撞信号时,向车门解锁控制单元发送驱动解锁指令,以使车门解锁控制单元控制车门解锁,其中,驱动解锁指令至少发送三次;确定驱动解锁指令的已发送次数;若已发送次数大于预设已发送次数,则确定车门的当前状态;若当前状态为解锁状态,则停止向车门解锁控制单元发送驱动解锁指令即可。
图2为本申请实施例提供的车门控制方法的流程示意图。该方法的执行主体可以为存储有车门控制系统的服务器或其它服务器,本实施例此处不做特别限制,如图2所示,该方法可以包括:
S201、在接收到车辆碰撞信号时,向车门解锁控制单元发送驱动解锁指令,以使车门解锁控制单元控制车门解锁,其中,驱动解锁指令至少发送三次。
车辆碰撞信号可以为车辆在发生碰撞时,产生的信号,比如,在一些实施例中,车辆碰撞信号可以通过汽车碰撞传感器发出,即可以在当车辆发生正面、侧面、后面碰撞以及翻滚和行人碰撞的情况后,汽车碰撞传感器根据车辆发生的碰撞强度而发出车辆碰撞信号。
车门解锁控制单元可以为用于控制汽车车门“解锁”或“锁定”的装置,在一些实施例中,车门解锁控制单元可以通过接收“解锁信号”或“锁定信号”,进行车门的解锁和锁定,在当车辆发生碰撞事故时,需要车门处于解锁状态,从而方便乘员打开车门离开事故现场,避免收到其他伤害,或方便救援人员对车内乘员进行营救。
其中,车门解锁控制单元发送的“解锁信号”可以为驱动解锁指令,车门解锁控制单元在收到驱动解锁指令后,可以执行车门的解锁操作。
为了避免在向车门解锁控制单元发送驱动解锁指令后,由于接触不良等原因,没有对车门进行解锁操作,因此可以向车门解锁控制单元发送多次驱动解锁指令,以保证车门解锁控制单元控制车门解锁。在一些实施例 中,可以通过车门控制系统向车门解锁控制单元发送两次以上驱动解锁指令。
其中,在本申请实施例中,在接收到车辆碰撞信号之后,向车门解锁控制单元发送驱动解锁指令之前的方法还可以包括:
通过车门控制系统中的车辆控制单元接收车辆碰撞信号。
车辆控制单元可以为CEM(Central Electronic Module,中央电子控制模块),车辆控制单元可以用作车辆的中央处理器,车辆控制单元可以通过接收信号的方式,对车辆内各个设备的参数进行调整。在本申请实施例中,车辆控制单元可以接收车辆碰撞信号,并将车辆碰撞信号发送至车门控制单元。
其中,车辆控制单元可以通过碰撞控制单元接收车辆碰撞信号,在本申请实施例中,在通过车门控制系统中的车辆控制单元接收车辆碰撞信号之前的方法还可以包括:
通过车门控制系统中的碰撞控制单元接收车辆碰撞信号;
在碰撞控制单元接收到车辆碰撞信号后,碰撞控制单元将车辆碰撞信号以预设的第二发送时长发送至车辆控制单元,以使车辆控制单元接收车辆碰撞信号。
碰撞控制单元可以为ACU(auto controled unite,碰撞控制器),其中,在一些实施例中,碰撞控制单元可以为汽车碰撞传感器。在车辆受到碰撞后,碰撞控制单元可以根据车辆发生的碰撞强度而发出车辆碰撞信号,并将车辆碰撞信号发送到车辆控制单元。
第二发送时长发可以是指碰撞控制单元将车辆碰撞信号发送至车辆控制单元的时长,其中,第二发送时长可以是根据需要任意设置的,其主要用于保证碰撞控制单元将车辆碰撞信号稳定的发送至车辆控制单元,在本申请实施例中,第二发送时长可以为4秒,也可以为其他设置的秒数。
其中,在本申请实施例中,车辆碰撞信号在碰撞控制单元和车辆控制单元之间的传输方式包括有线传输和/或无线传输。有线传输可以包括采用PWM(Pulse Width Modulation)信号的方式进行车辆碰撞信号的发送。无线传输可以包括采用CAN网络(Controller Area Network,控制器域网)进行车辆碰撞信号的发送。在使用时,当碰撞控制单元将车辆碰撞信号发送至车辆控制单元时,可以采用有线传输和无线传输的传输方式同时进行。
在车辆控制单元接收车辆碰撞信号之后,将车辆控制单元的使用模式改为碰撞模式。
车辆控制单元可以包括正常行驶模式和碰撞模式,碰撞模式为车辆发生碰撞后,车辆控制单元由正常行驶模式切换到的模式,当车辆控制单元处于碰撞模式时,车辆控制单元可以将车辆碰撞信号发送至车门控制单元,并对当前车辆碰撞信号发送的状态进行记录。
其中,车辆在发生碰撞后,由于加速度过高以及车身变形等现象,导致整车在碰撞瞬间车辆低压会断电或者短暂电压下降,这样使得车辆控制单元在使用时因为电压降低而发生重启现象,为了保证车辆控制单元在重启后也可以将车辆碰撞信号发送至车门控制单元,在本申请实施例中,车门控制方法还可以包括:
若车辆控制单元在向车门控制单元发送车辆碰撞信号时重启,则控制重启后的车辆控制单元继续向车门控制单元发送车辆碰撞信号。
其中,当车辆控制单元处于碰撞模式时,车辆控制单元可以对当前状态进行存储,比如,预设的第一发送时长为10秒,当车辆控制单元向车门控制单元发送的车辆碰撞信号在5秒时,发生降压问题而重启后,车辆控制单元可以在重启后继续向车门控制单元发送车辆碰撞信号,直至发送的时长满足预设的第一发送时长的要求。
在车辆控制单元的使用模式改为碰撞模式后,通过车辆控制单元将车辆碰撞信号以预设的第一发送时长发送至车门控制系统中的车门控制单元,以使车门控制单元根据车辆碰撞信号,向车门解锁控制单元发送驱动解锁指令,控制车门解锁。
车门控制单元可以为DM(Door module,四门控制模块),车门控制单元可以用于控制汽车的四个门的使用状态,例如,车门的“解锁”和“锁定”,车窗的“开启”和“关闭”。在本申请实施例中,车门控制单元可以通过车辆碰撞信号,生成驱动解锁指令,并将驱动解锁指令发送至车门解锁控制单元。
第一发送时长可以是指车辆控制单元将车辆碰撞信号发送至车门控制单元的时长,其中,第一发送时长可以是根据需要任意设置的,其主要用于保证车辆控制单元将车辆碰撞信号稳定的发送至车门控制单元,在本申请实施例中,第一发送时长可以为10秒,也可以为其他设置的秒数。
其中,第一发送时长和第二发送时长可以设置为相同的时长,也可以设置为不同的时长。
其中,在本申请实施例中,车辆控制单元和车门控制单元之间可以通过CAN网络进行车辆碰撞信号的发送。
S202、确定驱动解锁指令的已发送次数。
已发送次数可以指向车门解锁控制单元已经发送的驱动解锁指令的次数,在一些实施例中,驱动解锁指令在发送至可以以预定的频率进行发送,比如,以3秒为间隔,向车门解锁控制单元发送驱动解锁指令。在本申请实施例中,驱动解锁指令可以通过车门控制单元发送,车门控制单元在接收到车辆碰撞信号后,根据车辆碰撞信号可以以2秒为间隔向车门解锁控制单元发送驱动解锁指令。车辆碰撞信号发送驱动解锁指令可以通过计数模块进行获取统计。
S203、若已发送次数大于预设已发送次数,则确定车门的当前状态。
预设已发送次数为预先设定的次数,当已发送次数大于预设已发送次数时,则获取车门的当前状态,其中,当前状态可以指车门当前处于“锁定”状态还是“状态”。在一些实施例中,预设已发送次数为1次,当已发送次数为2次时,则可以通过车门控制单元确定车门的当前状态,或预设已发送次数为3次,当已发送次数为4次时,则可以通过车门控制单元确定车门的当前状态。
其中,为了避免车辆门锁开关因误触发解锁状态,以及因误触发锁定状态,因此,设置要求预设已发送次数,当已发送次数大于预设已发送次数时,获取车门的当前状态,来更加准确、可靠的对车门进行控制。
其中,在本申请实施例中,车门控制方法还可以包括:
若已发送次数小于预设已发送次数,则继续向车门解锁控制单元发送驱动解锁指令。
其中,已发送次数小于预设已发送次数可以指发送驱动解锁指令的次数未到预设已发送次数的要求。比如,预设已发送次数为3次,当已发送次数为2次。
S204、若当前状态为解锁状态,则停止向车门解锁控制单元发送驱动解锁指令。
解锁状态可以指乘员或救援人员可以直接打开车门,比如,在一些实 施例中,车门的解锁状态可以包括车辆门锁开关打开和车辆门把手弹出。
停止向车门解锁控制单元发送驱动解锁指令可以是指在已发送次数大于预设已发送次数后,车门处于解锁状态时,车门控制系统无需再向车门解锁控制单元发送驱动解锁指令。
其中,在本申请实施例中,车门控制方法还可以包括:若当前状态为锁定状态,则继续向车门解锁控制单元发送驱动解锁指令。
其中,当已发送次数大于预设已发送次数时,当前状态若还为锁定状态,则继续向车门解锁控制单元发送驱动解锁指令,以使车门解锁。在一些实施例中,为了保证车门解锁控制单元的使用寿命,发送驱动解锁指令的次数可以设置为10次,其中,预设已发送次数可以设置为3次。
其中,在本申请实施例中,车门控制方法还可以包括:
判断主电源的供电状态,主电源为与车门控制系统、车门解锁控制单元和车门连接的电源;
当主电源的供电状态为异常时,控制车门控制系统、车门解锁控制单元和车门与备用电源连接。
其中,主电源为设置在车辆内用于向车门控制系统、车门解锁控制单元和车门供电的主要电源。
主电源的供电状态包括“正常”和“异常”,其中,“正常”可以是指主电源与车门控制系统、车门解锁控制单元和车门的连接顺畅,“异常”可以是指主电源与车门控制系统、车门解锁控制单元和车门的连接中断。在本申请实施例中,主电源的供电状态可以通过连接在主电源和车门控制系统、车门解锁控制单元和车门之间的电压检测装置确定,当发生碰撞,使得主电源无法供电时,使用备用电源进行供电。
备用电源为设置在车辆内用于向车门控制系统、车门解锁控制单元和车门供电的备用电源,备用电源用于在主电源无法正常供电后的使用。在一些实施例中,主电源和备用电源可以是相互独立的电源。
在本申请实施例中,备用电源可以分别与车门控制系统中的各个单元、车门解锁控制单元和车门连接。而在一些实施例中,为了在降低成本的同时,保证车门可以正常、可靠的解锁,故备用电源也可以只与车门解锁控制单元和车门供电连接,从而保证车门解锁动作的执行。
本申请实施例可以在接收车辆碰撞信号时,向车门解锁控制单元发送 驱动解锁指令,以使车门解锁控制单元控制车门解锁;确定驱动解锁指令的已发送次数,其中,驱动解锁指令至少发送三次;若已发送次数大于预设已发送次数,则确定车门的当前状态;若当前状态为解锁状态,则停止向车门解锁控制单元发送驱动解锁指令。本申请实施例可以在进行车门控制时,通过多次发送驱动解锁指令,且保证在一定次数的驱动解锁指令发出后,才确定车门的当前状态,从而实现提高车辆在发碰撞时,对车门解锁控制的可靠性。
图3为本申请实施例提供的另一种车门控制方法的流程示意图,如图3所示,该方法可以包括:
S301、通过碰撞控制器接收碰撞信号;
S302、在碰撞控制器接收碰撞信号后,控制碰撞控制器将碰撞信号以PWM信号和CAN网络信号的方式发送至车辆中央控制器,其中,碰撞控制器发送碰撞信号的时长为4秒;
S303、在车辆中央控制器接收碰撞信号后,控制车辆中央控制器将碰撞信号以CAN网络信号的方式发送车门控制器,其中,车辆中央控制器发送碰撞信号的时长10秒;
S304、在车门控制器接收碰撞信号后,车门控制器根据碰撞信号,生成碰撞指令;
S305、控制车门控制器将碰撞指令发送至门锁电机,以使门锁电机对车门进行解锁,其中,车门控制器发送碰撞指令的次数为10次,且在第3次后,确定车门的解锁状态;
S306、当车门控制器发送碰撞指令的次数大于3次,且车门解锁时,停止向车门发送碰撞指令。
图4为本申请实施例提供的车门控制方法的模块流程示意图,如图4所示,该流程可以包括:
碰撞信号通过CAN网络传输至碰撞控制器ACU中;碰撞控制器ACU通过PWM硬线和CAN网络持续向车辆中央控制器CEM发送碰撞信号至少4秒;车辆中央控制器CEM通过和CAN网络持续向车辆门控制器DM发送碰撞信号10秒,其中,当车辆中央控制器CEM由于电压下降,导致重启后仍然发送碰撞信号;车辆门控制器DM单次驱动门锁电机200毫秒,且至少驱动3次,共驱动10次,其中,前3次与门锁电机的状态不关联,后7次与门锁 电机的状态关联;门锁电机驱动车辆门锁电机打开和车辆门把手弹出。
其中,主蓄电池与碰撞控制器ACU、车辆中央控制器CEM、车辆门控制器DM、门锁电机、车辆门锁电机和车辆门把手连接,备份电池与门锁电机、车辆门锁电机和车辆门把手连接。
由此,本申请实施例可以保证碰撞信号在传递时,能准确、可靠的进行传递,并使得车门在解锁时,能避免车门在并未解锁的状态下反馈解锁状态所导致的车门无法打开,从而实现提高车辆在发碰撞时,对车门解锁控制的可靠性。
图5为本申请实施例提供的车门控制装置的结构示意图。如图5所示,该车门控制装置50包括:发送模块501、第一确定模块502、第二确定模块503、停止模块504。其中:

第一确定模块502,用于确定驱动解锁指令的已发送次数;
第二确定模块503,用于若已发送次数大于预设已发送次数,则确定车门的当前状态;
停止模块504,用于若当前状态为解锁状态,则停止向车门解锁控制单元发送驱动解锁指令。
在本申请实施例中,发送模块501还可以具体用于:
通过车门控制系统中的车辆控制单元接收车辆碰撞信号;
在车辆控制单元接收车辆碰撞信号之后,将车辆控制单元的使用模式改为碰撞模式;
在车辆控制单元的使用模式改为碰撞模式后,通过车辆控制单元将车辆碰撞信号以预设的第一发送时长发送至车门控制系统中的车门控制单元,以使车门控制单元根据车辆碰撞信号,多次向车门解锁控制单元发送驱动解锁指令,控制车门解锁。
在本申请实施例中,发送模块501还可以具体用于:
若车辆控制单元在向车门控制单元发送车辆碰撞信号时重启,则控制重启后的车辆控制单元继续向车门控制单元发送车辆碰撞信号。
在本申请实施例中,发送模块501还可以具体用于:
通过车门控制系统中的碰撞控制单元接收车辆碰撞信号;
在碰撞控制单元接收到车辆碰撞信号后,碰撞控制单元将车辆碰撞信号以预设的第二发送时长发送至车辆控制单元,以使车辆控制单元接收车辆碰撞信号。
在本申请实施例中,发送模块501还可以具体用于:
车辆碰撞信号在碰撞控制单元和车辆控制单元之间的传输方式包括有线传输和/或无线传输。
在本申请实施例中,发送模块501还可以用于:
若已发送次数小于预设已发送次数,则继续向车门解锁控制单元发送驱动解锁指令。
在本申请实施例中,停止模块504还可以用于:
判断主电源的供电状态,主电源为与车门控制系统、车门解锁控制单元和车门连接的电源;
当主电源的供电状态为异常时,控制车门控制系统、车门解锁控制单元和车门与备用电源连接。
由上可知,本实施例的车门控制装置由发送模块501,用于在接收到车辆碰撞信号时,向车门解锁控制单元发送驱动解锁指令,以使车门解锁控制单元控制车门解锁,其中,驱动解锁指令至少发送三次;由第一确定模块502,用于确定驱动解锁指令的已发送次数;由第二确定模块503,用于若已发送次数大于预设已发送次数,则确定车门的当前状态;由停止模块504,用于若当前状态为解锁状态,则停止向车门解锁控制单元发送驱动解锁指令。由此,可以在进行车门控制时,通过多次发送驱动解锁指令,且保证在一定次数的驱动解锁指令发出后,才确定车门的当前状态,从而实现提高车辆在发碰撞时,对车门解锁控制的可靠性。
