需要说明的是，当使用充电桩等供电设备对汽车进行充电时，CP(Control Pilot，交流充电控制导引)信号表示用于充电引导的信号，CC(Charge Confirm，充电确认)信号表示用于连接确认的信号。
参照图1，本申请实施例提供了一种唤醒控制装置100。该唤醒控制装置100包括第一状态检测模块110、使能控制模块120、唤醒检测模块130和主控模块140。第一状态检测模块110用于检测CP信号的状态，并根据CP信号的状态生成第一状态信号。使能控制模块120与第一状态检测模块110连接，使能控制模块120用于接收CC信号，并根据CC信号和第一状态信号生成使能复位信号。唤醒检测模块130用于根据CP信号生成唤醒需求信号。主控模块140分别与第一状态检测模块110、使能控制模块120、唤醒检测模块130连接，主控模块140用于根据第一状态信号、使能复位信号、唤醒需求信号生成第一唤醒控制信号。
具体地，唤醒检测模块130用于接收CP信号，并根据该CP信号生成用于表示是否需要进行唤醒操作的唤醒需求信号。第一状态检测模块110用于接收CP信号，并判断该CP信号的状态是否符合唤醒规定，从而生成对应的第一状态信号。使能控制模块120用于接收CC信号和第一状态信号，进而根据CC信号的状态、第一状态信号判断CC信号与CP信号是否会产生唤醒冲突，并生成对应的使能复位信号。主控模块140用于在第一状态信号符合CP唤醒规定、唤醒需求信号表示需进行唤醒操作、使能复位信号表示CC信号与CP信号无唤醒冲突时，生成对应的第一唤醒控制信号，以使得BMS或其他车载充电装置能够根据该第一唤醒控制信号控制汽车唤醒充电。
例如，参照表1，CP信号包括直流电压信号和PWM信号两种状态。其中，直流电压信号包括+12V信号和+9V信号，PWM信号包括+9V PWM信号和+6V PWM信号。根据唤醒规 定，当CP信号为+12V信号或+9V信号时，表示充电桩等供电设备的交流充电处于连接确认和准备就绪阶段，此时CP信号不作唤醒处理，因此第一状态检测模块110生成低电平的第一状态信号。当CP信号为PWM信号时，表示充电桩等供电设备处于预约充电阶段，此时CP信号是否满足唤醒规定由其他控制器进行判断控制。当预约充电阶段表示预约计时中时，CP信号不作唤醒处理，第一状态检测模块110生成低电平的第一状态信号；当预约充电阶段表示预约计时结束时，第一状态检测模块110生成高电平的第一状态信号，即CP信号符合唤醒规定。
表1：
CP信号 第一状态信号
+12V 0
+9V 0
+9V PWM 1
+6V PWM 1
+9V PWM 1
参照表2，CP信号为充电引导信号，即可根据CP信号的状态反馈是否需要进行唤醒操作。在相关规定中(例如GB/T 20234-2015)，只有当CP信号的状态为+6V PWM信号时，充电桩等供电设备才输出对应的交流电压。因此，CP信号的状态为+6V PWM信号时，唤醒检测模块130判断需要进行唤醒操作，此时唤醒检测模块130生成高电平的唤醒需求信号。
表2：
CP信号 唤醒需求信号
+12V 0
+9V 0
+9V PWM 0
+6V PWM 1
+9V PWM 0
参照表3，当CC信号为高电平信号时，表明CC信号处于唤醒操作阶段。此时，为了避免CP信号与CC信号产生唤醒冲突，无论CP信号是否符合唤醒规定，即无论第一状态信号为高电平信号或低电平信号，使能控制模块120生成的使能复位信号都为高电平信号，以对CP信号的唤醒操作进行清除。当CC信号为低电平信号时，表明CC信号未处于唤醒操作阶段，此时使能复位信号的电平由第一状态信号控制，即第一状态信号为低电平时，使能复位信号为高电平，以避免进行充电唤醒；当第一状态信号为高电平时，使能复位信号为低电平， 以使得主控模块140能够根据CP信号进行充电唤醒。
表3：
第一状态信号 CC信号 使能复位信号
0 0 1
1 0 0
0 1 1
1 1 1
参照表4，当第一状态信号符合CP唤醒规定、唤醒需求信号表示需要进行唤醒操作、使能复位信号表示CC信号与CP信号无唤醒冲突时，即第一状态信号为高电平信号、唤醒需求信号为高电平信号、使能复位信号为低电平信号时，主控模块140生成高电平的第一唤醒控制信号，以唤醒汽车进行充电操作。在其余状态下，第一唤醒控制信号均为低电平信号，即其余状态均不能通过CP信号进行唤醒充电。
表4：

本申请实施例提供的唤醒控制装置通过第一状态检测模块对CP信号的状态进行检测，通过使能控制模块判断CC信号与CP信号是否发生唤醒冲突，通过唤醒检测模块检测CP信号的唤醒需求，从而使得主控模块能够根据第一状态信号、使能复位信号、唤醒需求信号生成对应的第一唤醒控制信号，进而实现了根据CP信号进行唤醒控制，并解决了CP信号与CC信号的唤醒冲突问题。
以下，分别对第一状态检测模块110、使能控制模块120、唤醒检测模块130、主控模块140的具体元器件及其连接关系进行具体说明。但应理解的是，下列说明仅为示例性的，即除下列所描述的元器件以外，其余能够实施上述原理的元器件及其连接关系都应属于本申请实施例的保护范围。
参照图2，在一些实施例中，第一状态检测模块110包括电平转换单元111和状态检测单元112。电平转换单元111用于对CP信号进行电平转换操作。状态检测单元112与电平转换 单元111连接，用于检测电平转换操作后的CP信号的状态，并根据电平转换操作后的CP信号的状态生成状态检测信号。
具体地，电平转换单元111用于接收CP信号，并将+12V(或+9V)的直流电压CP信号转换为3.3V(或5V)的直流电压信号，PWM信号转换后仍为PWM信号。状态检测单元112用于检测电平转换操作后的CP信号的状态是否为PWM信号，若CP信号为3.3V(或5V)的直流电压信号，则生成低电平的状态检测信号；若CP信号为PWM信号，则生成高电平的状态检测信号，从而实现对CP信号的状态检测。可以理解的是，直流电压CP信号转换成直流电压信号的具体取值还可以根据实际需要进行适应性调整，本申请实施例不作具体限定。
参照图3，在一些实施例中，电平转换单元包括第一电阻R1、第二电阻R2、第一控压流元件Q1、第三电阻R3、转换电源113、第四电阻R4、第二控压流元件Q2和第五电阻R5。第一电阻R1的一端用于接收CP信号；第二电阻R2的一端与第一电阻R1的另一端连接，第二电阻R2的另一端接地；第一控压流元件Q1的基极与第二电阻R2的一端连接，第一控压流元件Q1的发射极接地；第三电阻R3的一端与第一控压流元件Q1的集电极连接；转换电源113与第三电阻R3的另一端连接；第四电阻R4的一端与第一控压流元件Q1的集电极连接；第二控压流元件Q2的基极与第四电阻R4的另一端连接，第二控压流元件Q2的发射极与转换电源113连接；第五电阻R5的一端与第二控压流元件Q2的集电极连接，第五电阻R5的另一端接地。
具体地，转换电源113用于提供转换直流电压，即转换电源113可为3.3V电源、5V电源等。第一控压流元件Q1为NPN型三极管，第二控压流元件Q2为PNP型三极管。CP信号经过第一电阻R1流向第一控压流元件Q1的基极，从而使得第一控压流元件Q1导通，进而在第五电阻R5的两端产生CP信号经过电平转换操作后所形成的直流电压信号或PWM信号。
参照图2至图4，在一些实施例中，状态检测单元112包括第一电容C1、二极管D1、第二电容C2和第六电阻R6。第一电容C1的一端与第五电阻R5的一端连接；二极管D1的阳极与第一电容C1的另一端连接，二极管D1的阴极分别与使能控制模块120、主控模块140连接；第二电容C2的一端与二极管D1的阴极连接，第二电容C2的另一端接地；第六电阻R6与第二电容C2并联连接。
具体地，第一电容C1为AC耦合电容，第一电容C1、二极管D1、第二电容C2和第六电阻R6构成一个PWM交流电源转换电路。因此，当经过电平转换操作后的CP信号为直流电压信号时，第六电阻R6的两端将生成低电平的第一状态信号；当经过电平转换操作后的 CP信号为PWM信号时，第六电阻R6的两端将生成高电平的第一状态信号，从而实现对CP信号的状态检测。
参照图2至图4，在一些实施例中，使能控制模块120包括第一非门Q3、第一与门Q4和第二非门Q5。第一非门Q3的输入端用于接收CC信号；第一与门Q4的输入端分别与第一状态检测模块110、第一非门Q3的输出端连接；第二非门Q5的输入端与第一与门Q4的输出端连接，第二非门Q5的输出端与主控模块140连接。
具体地，使能控制模块120通过逻辑电路实现CC信号与CP信号的唤醒冲突检测。第一与门Q4的输入端分别与第一非门Q3、第三电阻R3的一端连接，即第一与门Q4用于对第一状态信号和CC信号的反信号进行与操作。当第一与门Q4生成高电平信号时，第二非门Q5生成的使能复位信号为低电平信号，即表明此时CC信号无唤醒操作。因此，主控模块140可在CP信号符合唤醒规定、唤醒需求信号表示需要进行唤醒操作时，生成高电平的第一唤醒控制信号，以控制BMS或其他车载充电装置根据CP信号对汽车进行唤醒充电。
参照图2至图4，在一些实施例中，唤醒检测模块130包括唤醒检测单元131和控制单元132。唤醒检测单元131用于检测CP信号的电压和/或占空比；控制单元132与唤醒检测单元131连接，用于根据CP信号的电压和/或占空比生成唤醒需求信号。
具体地，唤醒检测单元131用于检测CP信号为直流电压信号时的最大电压，和/或用于检测CP信号为PWM信号时的占空比。控制单元132用于接收该最大电压或占空比，并根据该最大电压或占空比生成对应的唤醒需求信号。当唤醒需求信号为高电平信号时，表明充电桩等供电设备能够提供交流电压，此时可对BMS或其他车载充电装置进行唤醒充电。
参照图2至图4，在一些实施例中，主控模块140包括D触发器和第二与门Q6。D触发器的输入端分别与使能控制模块120、唤醒检测模块130连接；第二与门Q6的输入端分别与D触发器的输出端、第一状态检测模块110连接。
具体地，D触发器的D端与所述控制单元132连接，用于接收唤醒需求信号；D触发器的CP端与控制单元132连接，用于接收控制单元132发送的时钟信号；D触发器的RD端(高电平有效)与第二非门Q5的输出端连接，用于接收使能复位信号；D触发器的Q端与第二与门Q6的输入端连接。因此，当使能复位信号为高电平信号时，无论唤醒需求信号为何种状态，D触发器Q端的输出信号都为低电平信号。此时，无论第一状态信号为何种状态，第二与门Q6的输出信号(即第一唤醒控制信号)都为低电平信号，从而避免了CP信号与CC信号的唤醒冲突。
参照图5，在一些实施例中，唤醒控制装置100还包括第二状态检测模块150。第二状态 检测模块150与主控模块140连接，第二状态检测模块150用于检测硬线信号的状态，并根据硬线信号的状态生成第二状态信号。
具体地，当唤醒控制装置100包括第二状态检测模块150时，主控模块140根据第二状态信号、第一状态信号、使能复位信号和唤醒需求信号生成第二唤醒控制信号，以避免硬线信号、CP信号、CC信号三者出现唤醒冲突。在一些具体地实施例中，第二状态检测模块150包括电平转换单元，该电平转换单元的输出端与第二与门Q6的输入端连接。可以理解的是，第二状态检测模块150的电平转换单元与第一状态检测模块110的电平转换单元111功能相同，因此本申请实施例不再对第二状态检测模块150的电平转换单元进行赘述。
参照图6，本申请实施例还提供了一种唤醒控制系统，应用于汽车。该唤醒控制系统包括：如上述任一实施例所描述的唤醒控制装置100和电池管理系统200。电池管理系统200与唤醒控制装置100连接，电池管理系统200用于根据第一唤醒控制信号或第二唤醒控制信号控制汽车的充电状态。
可见，上述唤醒控制装置实施例中的内容均适用于唤醒控制系统的实施例中，本唤醒控制系统实施例所具体实现的功能与上述唤醒控制装置实施例相同，并且达到的有益效果与上述唤醒控制装置实施例所达到的有益效果也相同。
本申请实施例还提供了一种汽车，该汽车包括如上述实施例所描述的唤醒控制系统。
可见，上述唤醒控制系统实施例中的内容均适用于本汽车的实施例中，本汽车实施例所具体实现的功能与上述唤醒控制系统实施例相同，并且达到的有益效果与上述唤醒控制系统实施例所达到的有益效果也相同。
上面结合附图对本申请实施例作了详细说明，但是本申请不限于上述实施例，在所属技术领域普通技术人员所具备的知识范围内，还可以在不脱离本申请宗旨的前提下作出各种变化。此外，在不冲突的情况下，本申请的实施例及实施例中的特征可以相互组合。
