S101、当电动汽车在当前时刻上发生预先设定的事件时，获取电动汽车的行驶状态以及电动汽车的HCU在当前时刻上的上下电模式；其中，上下电模式包括以下其中之一：初始化模式、正常上电模式、正常下电模式、故障下电模式、慢充上电模式、慢充加热上电模式、快充上电模式、快充加热上电模式。
在本步骤中，当电动汽车在当前时刻上发生预先设定的事件时，电子设备可以获取电动汽车的行驶状态以及电动汽车的HCU在当前时刻上的上下电模式；其中，上下电模式包括以下其中之一：初始化模式、正常上电模式、正常下电模式、故障下电模式、慢充上电模式、慢充加热上电模式、快充上电模式、快充加热上电模式。本申请涉及的电动汽车可以包括电动汽车动力系统，该电动汽车动力系统主要是由驱动电机、动力电池组、电机逆变器、直流转换器、充电机、空调系统等组成部件构成，同时还具有与每个组成部件相对应的控制器。其中，控制器包括了HCU、电机控制器(Motor Control Unit，MCU)、电池管理系统(Battery Management System，BMS)等，多个控制器之间通过控制器局域网总线(Controller Area Network，CAN)网络进行通信。为了更有效地进行电动汽车高压上下电模式管理和控制，在HCU软件内部设计了四个程序模块。图2为本申请实施例提供的一种高压上下电控制架构示意图。如图2所示，HCU内部模块可以包括：高压上下电模块、电机控制模块、电池管理模块以及故障处理模块；其中，高压上下电模块是HCU整车控制模型中的一个重要模块，高压上下电模块中定义了多种与高压上下电相关的模式。高压上下电模块通过收集相关的输入信息，包括驾驶员操作钥匙状态、车辆上下电请求信号、电机状态信号、电池状态信号、充电状态信号、直流-直流(Direct Current-Direct Current，DCDC)状态信号以及其他输入信号等。HCU中的高压上下电模块，根据外部输入信号，再结合驾驶员的操作需求、车辆以及动力总成状态，实现高压上下 电模块内不同模式之间的切换控制。高压上下电模块的工作模式可以包括以下8种模式：初始化模式、正常上电模式、正常下电模式、故障下电模式、慢充上电模式、慢充加热上电模式、快充上电模式、快充加热上电模式。HCU通过模式条件及控制策略方法设计，实现高压上下电模块内部不同模式之间的切换控制。
S102、根据电动汽车在当前时刻上发生的事件、电动汽车的行驶状态以及HCU在当前时刻上的上下电模式，确定HCU在下一个时刻上的上下电模式。
在本步骤中，电子设备可以根据电动汽车在当前时刻上发生的事件、电动汽车的行驶状态以及HCU在当前时刻上的上下电模式，确定HCU在下一个时刻上的上下电模式。电子设备可以根据电动汽车在当前时刻上发生的事件、电动汽车的行驶状态以及HCU在当前时刻上的上下电模式，判断电动汽车在当前时刻上是否满足任意一个上下电模式所对应的切换条件；若电动汽车在当前时刻上满足任意一个上下电模式所对应的切换条件，则电子设备可以确定出HCU在下一个时刻上的上下电模式为该任意一个上下电模式。也就是说，在以下8种上下电模式中，初始化模式、正常上电模式、正常下电模式、故障下电模式、慢充上电模式、慢充加热上电模式、快充上电模式、快充加热上电模式，每一种模式对应各自的切换条件，如果电动汽车在当前时刻上满足其中任意一种上下电模式所对应的切换条件，则可以确定HCU在下一个时刻上的上下电模式为该任意一种上下电模式。初始化模式所对应的切换条件为：电动汽车在当前时刻上接收到驾驶员通过操作钥匙发送的低压上电请求；正常上电模式所对应的切换条件为：HCU在当前时刻上的上下电模式为初始化模式，并且电动汽车在当前时刻上接收到驾驶员通过操作钥匙发送的高压上电请求；慢充上电模式所对应的切换条件为：HCU在当前时刻上的上下电模式为初始化模式、电动汽车有慢充充电枪连接、电动汽车处于慢充状态、电动汽车在当前时刻上接收到驾驶员通过操作钥匙发送的高压上电请求或者电动汽车在当前时刻上接收到驾驶员通过远程操作发送的高压上电指令；快充上电模式所对应的切换条件为：HCU在当前时刻上的上下电模式为初始化模式、电动汽车有快充充电枪连接、电动汽车处于快充状态、电动汽车在当前时刻上接收到驾驶员通过操作钥匙发送的高压上电请求或者电动汽车在当前时刻上接收到驾驶员通过远程操作发送的高压上电指令。另外，慢充加热上电模式所对应的切换条件为：HCU在当前时刻上的上下电模式为慢充上电模式、电动汽车的电池有加热需求、电动汽车的加热器件满足工作条件；快充加热上电模式所对应的切换条件为：HCU在当前时刻上的上下电模式为快充上电模式、电动汽车的电池有加热需求、电动汽车的加热器件的正温度系数(Positive Temperature Coefficien，PTC)满足工作条件。还有，正常下电模式所对应的切换条件为：HCU向电池管理模块发送充电停止 指令、电动汽车的充电机、加热器件和空调系统处于禁止使能状态、电池管理模块向电池管理系统发送高压下电请求指令、HCU接收到电机控制器和电池管理系统发送的高压下电允许信号、HCU接收到电机控制器反馈的母线电压小于预定阈值。此外，故障下电模式所对应的切换条件包括：正常运行过程中的下电切换条件、慢充上电模式下的下电切换条件、慢充加热上电模式下的下电切换条件、快充上电模式下的下电切换条件以及快充加热上电模式下的下电切换条件；其中，正常运行过程中的下电切换条件为：电动汽车出现高压上电故障、或者电动汽车出现电机严重故障、或者电动汽车出现电池严重故障；慢充上电模式下的下电切换条件为：电动汽车出现禁止慢充故障、或者电动汽车出现慢充高压上电失败；慢充加热上电模式下的下电切换条件为：电动汽车出现禁止慢充加热故障、或者电动汽车出现慢充加热高压上电失败；快充上电模式下的下电切换条件为：电动汽车出现禁止快充故障、或者电动汽车出现快充高压上电失败；快充加热上电模式下的下电切换条件为：电动汽车出现禁止快充加热故障、或者电动汽车出现快充加热高压上电失败。
S103、在下一个时刻上将HCU在当前时刻上的上下电模式切换为HCU在下一个时刻上的上下电模式；并基于HCU在下一个时刻上的上下电模式对电动汽车进行对应的控制操作。
在本步骤中，电子设备可以在下一个时刻上将HCU在当前时刻上的上下电模式切换为HCU在下一个时刻上的上下电模式；并基于HCU在下一个时刻上的上下电模式对电动汽车进行对应的控制操作。电子设备可以先获取HCU在下一个时刻上的上下电模式所对应的控制方式；然后根据HCU在下一个时刻上的上下电模式所对应的控制方式，对电动汽车进行对应的控制操作。
本申请实施例提出的上下电模式的切换控制方法，当电动汽车在当前时刻上发生预先设定的事件时，先获取电动汽车的行驶状态以及电动汽车的HCU在当前时刻上的上下电模式；然后根据电动汽车在当前时刻上发生的事件、电动汽车的行驶状态以及HCU在当前时刻上的上下电模式，确定HCU在下一个时刻上的上下电模式；接着在下一个时刻上将HCU在当前时刻上的上下电模式切换为HCU在下一个时刻上的上下电模式；并基于HCU在下一个时刻上的上下电模式对电动汽车进行对应的控制操作。也就是说，在本申请的技术方案中，将电动汽车高压上下电模式作为考虑点，通过设计开发不同模式的条件，以及创建不同模式的切换方案，并制定了对应的控制策略方法。相对于已有的技术方案，本申请基于电动汽车的运行特点，开发出不同的模式及其控制策略方法，提升了车辆高压上下电过程运行的稳定性、安全性和可靠性。而在相关技术中，并非是以整车控制器为核心的高压上下电模式切换控制方法。而且专门针对电动汽车高压上下电过程中的模式切换及控制策略方法公开较少、公开资料有限。 因此，和相关技术相比，本申请实施例提出的上下电模式的切换控制方法，能够有效地对不同高压上下电涉及的模式进行控制，从而提高车辆运行的稳定性、安全性和可靠性；并且，本申请实施例的技术方案实现简单方便、便于普及，适用范围更广。

在本申请的具体实施例中，初始化模式所对应的切换条件为：电动汽车在当前时刻上接收到驾驶员通过操作钥匙发送的低压上电请求；正常上电模式所对应的切换条件为：HCU在当前时刻上的上下电模式为初始化模式，并且电动汽车在当前时刻上接收到驾驶员通过操作钥匙发送的高压上电请求；慢充上电模式所对应的切换条件为：HCU在当前时刻上的上下电模式为初始化模式、电动汽车有慢充充电枪连接、电动汽车处于慢充状态、电动汽车在当前时刻上接收到驾驶员通过操作钥匙发送的高压上电请求或者电动汽车在当前时刻上接收到驾驶员通过远程操作发送的高压上电指令；快充上电模式所对应的切换条件为：HCU在当前时刻上的上下电模式为初始化模式、电动汽车有快充充电枪连接、电动汽车处于快充状态、电动汽车在当前时刻上接收到驾驶员通过操作钥匙发送的高压上电请求或者电动汽车在当前时刻上接收到驾驶员通过远程操作发送的高压上电指令。慢充加热上电模式所对应的切换条件为：HCU在当前时刻上的上下电模式为慢充上电模式、电动汽车的电池有加热需求、电动汽车的加热器件满足工作条件；快充加热上电模式所对应的切换条件为：HCU在当前时刻上的上下电模式为快充上电模式、电动汽车的电池有加热需求、电动汽车的加热器件PTC满足工作条件。正常下电模式所对应的切换条件为：HCU向电池管理模块发送充电停止指令、电动汽车的充电机、加热器件和空调系统处于禁止使能状态、电池管理模块向电池管理系统发送高压下电请求指令、HCU接收到电机控制器和电池管理系统发送的高压下电允许信号、HCU接收到电机控制器反馈的母线电压小于预定阈值。此外，故障下电模式所对应的切换条件包括：正常运行过程中的下电切换条件、慢充上电模式下的下电切换条件、慢充加热上电模式下的下电切换条件、快充上电模式下的下电切换条件以及快充加热上电模式下的下电切换条件；其中，正常运行过程中的下电切换条件为：电动汽车出现高压上电故障、或者电动汽车出现电机严重故障、或者电动汽车出现电池严重故障；慢充上电模式下的下电切换条件为：电动汽车出现禁止慢充故障、或者电动汽车出现慢充高压上电失败；慢充加热上电模式下的下电切换条件为：电动汽车出现禁止慢充加热故障、或者电动汽车出现慢充加热高压上电失败；快充上电模式下的下电切换条件为：电动汽车出现禁止快充故障、或者电动汽车出现快充高压上电失败；快充加热上电模式下的下电切换条件为：电动汽车出现禁止快充加热故障、或者电动汽车出现快充加热高压上电失败。

S304、在下一个时刻上将HCU在当前时刻上的上下电模式切换为HCU在下一个时刻上的上下电模式；并基于HCU在下一个时刻上的上下电模式对电动汽车进行对应的控制操作。
图4为本申请实施例提供的一种不同模式的切换流程示意图。如图4所示，在初始化模式下，若驾驶员操作钥匙KeyStart高压上电，或者通过远程启动上高压电，则HCU控制车辆进入正常上电模式；在初始化模式下，如果车辆的慢充充电枪连接且车辆已处于慢充状态，若驾驶员操作钥匙KeyStart高压上电，或者通过远程启动上高压电，则HCU控制车辆进入慢充上电模式；在初始化模式下，如果车辆的快充充电枪连接且车辆已处于快充状态，若驾驶员操作钥匙KeyStart高压上电，或者通过远程启动上高压电，则HCU控制车辆进入快充上电模式；在慢充上电模式下，如果电池有加热需求且PTC可以使能工作，则HCU控制车辆进入慢充加热上电模式；在快充上电模式下，如果电池有加热需求且PTC可以使能工作，则HCU控制车辆进入快充加热上电模式。在上述不同的上电模式下，若要进入正常下电模式，需满足实现以下控制条件：1)HCU内部上下电模块向电池控制模块发送充电停止指令；2)充电机、PTC、HVAC禁止使能；3)HCU电池控制模块向BMS发送高压下电请求指令；4)HCU接收到MCU和BMS发送的高压下电允许信号；5)HCU接收到MCU反馈的母线电压小于一定值；满足1)至5)时，则HCU控制进入正常下电模式。
本申请在不同的模式下，有不同的控制方法。举例说明，在慢充高压上电模式下，要控制完成慢充高压上电的方法包括如下步骤：1)HCU为初始化模式且车辆处于慢充状态；2)驾驶员操作钥匙上高压、或者远程启动上高压；3)HCU内部的高压上下电模块向电池控制模块发送慢充上电请求指令；4)若电池控制模块返回慢充上电请求允许信号，则HCU向BMS发送慢充上电请求指令；5)若BMS反馈慢充上电请求允许信号，HCU向DCDC发送使能指令；6)若DCDC反馈使能完成，HCU向充电机发送慢充上电请求指令；7)若充电机反馈慢充上电请求允许信号，则HCU控制车辆完成慢充高压上电；通过1)至7)，HCU控制车辆完成慢充高压上电。综上，通过HCU内部模块设计，开发了高压上下电模块内部不同模式以及控制策略方法，制定了不同模式的切换方案，实现了不同模式的有效切换控制，有效提升了车辆高压上下电的稳定性、安全性和可靠性。
本申请基于电动汽车运行状态为考虑点，通过设计HCU内部高压上下电模块，在该模块下制定不同模式的条件、策略及控制方法，更能够有效地对不同高压上下电涉及的模式进行控制，从而提高车辆运行的稳定性、安全性和可靠 性。关键点在于：1)电动汽车高压上下电模式控制系统架构设计；2)电动汽车不同高压上下电模式方案制定；3)电动汽车不同高压上下电模式的切换控制方法；4)电动汽车在慢充高压上电模式下的控制方法。本申请可以通过电机控制器MCU来进行车辆高压上下电不同模式的设计及控制策略开发，但会造成MCU控制器的工作负荷加大，且MCU控制器需要采集较多的信号，需要更改电机软件架构。HCU作为整车核心控制器，其协同控制判断较为全面，HCU可获取多个动力源运行状态信号，综合进行判断，故采用HCU进行高压上下电不同模式的设计及控制更合适。
本申请实施例提出的上下电模式的切换控制方法，当电动汽车在当前时刻上发生预先设定的事件时，先获取电动汽车的行驶状态以及电动汽车的HCU在当前时刻上的上下电模式；然后根据电动汽车在当前时刻上发生的事件、电动汽车的行驶状态以及HCU在当前时刻上的上下电模式，确定HCU在下一个时刻上的上下电模式；接着在下一个时刻上将HCU在当前时刻上的上下电模式切换为HCU在下一个时刻上的上下电模式；并基于HCU在下一个时刻上的上下电模式对电动汽车进行对应的控制操作。也就是说，在本申请的技术方案中，将电动汽车高压上下电模式作为考虑点，通过设计开发不同模式的条件，以及创建不同模式的切换方案，并制定了对应的控制策略方法。相对于已有的技术方案，本申请基于电动汽车的运行特点，开发出不同的模式及其控制策略方法，提升了车辆高压上下电过程运行的稳定性、安全性和可靠性。而在相关技术中，并非是以整车控制器为核心的高压上下电模式切换控制方法。而且专门针对电动汽车高压上下电过程中的模式切换及控制策略方法公开较少、公开资料有限。因此，和相关技术相比，本申请实施例提出的上下电模式的切换控制方法，能够有效地对不同高压上下电涉及的模式进行控制，从而提高车辆运行的稳定性、安全性和可靠性；并且，本申请实施例的技术方案实现简单方便、便于普及，适用范围更广。
