实施例一
图1是本申请实施例一提供的一种控制器功能更新方法的流程图。本实施例提供的控制器功能更新方法可适用于对控制器功能的动态更新的情况，该方法可以应用于车辆中。如图1所示，控制器功能更新方法可以包括：
S110、通过车辆中的网关控制器，接收服务器发送的至少一个目标功能报文，其中，至少一个目标功能报文可以是指服务器基于预设报文生成方式和待修改功能的至少一个目标控制器对应的目标功能配置信息生成的。
网关(Gateway，GW)控制器可以是指在车辆上设置为自动接收和控制 广播功能报文的设备。服务器是指可以设置为生成功能报文的设备。预设报文生成方式可以是指在服务器中预先设定的用于生成功能报文的方式。待修改功能可以是指车辆的控制器中需要进行修改的功能。目标控制器可以是当前需要更新功能的控制器。目标控制器的数量可以为一个或多个。目标控制器可以包括网关控制器和/或车载控制器。车载控制器可以包括车辆中除网关控制器之外的控制器。目标功能配置信息可以是指根据预设报文生成方式生成的用于更新目标控制器功能的数据信息。
车辆中的网关控制器可以接收服务器通过空中刷写(Over-The-Air，OTA)方式发送的至少一个目标功能报文。其中，目标功能报文与目标控制器之间的对应关系可以是一对多的对应关系，即一个目标功能报文可以更新多个目标控制器的功能，以便利用一个目标功能报文可以批量更新具有同一功能的多个控制器，提高功能更新效率。
S120、通过网关控制器，将接收到的至少一个目标功能报文进行广播，以使车辆中的至少一个车载控制器接收到至少一个目标功能报文。
网关控制器可以通过但不限于控制器局域网络(Controller Area Network，CAN)总线与每个车载控制器相连。网关控制器广播周期可以是100ms。
网关控制器可以将接收到的至少一个目标功能报文，通过CAN总线向至少一个车载控制器进行广播，以使车辆中的至少一个车载控制器接收到至少一个目标功能报文。本实施例中的网关控制器可以对接收到的每个目标功能报文进行重复广播预设次数，以便保证每个车载控制器可以接收到每个目标功能报文。重复广播可以是指将至少一个目标功能报文全部广播一次之后，再进行下次的广播，以保证将至少一个目标功能报文全部广播，并全部被车载控制器接收。
S130、通过每个车载控制器，基于与预设报文生成方式相匹配的预设报文解析方式，对接收到的至少一个目标功能报文进行解析，并基于解析出的与当前车载控制器相匹配的目标车载功能配置信息，对当前车载控制器进行功能更新。
预设报文解析方式可以是指预先设定的与预设报文生成方式相反的用于解析报文的方式。当前车载控制器可以是指当前执行功能更新操作的车载控制器。目标车载功能配置信息可以是指通过当前车载控制器对接收到的目标功能报文进行解析并与当前车载控制器相匹配的信息，可以用于对当前控制器进行功能更新。
每个车载控制器可以基于与预设报文生成方式相匹配的预设报文解析方 式，对接收到的至少一个目标功能报文进行解析，若每个车载控制器可以解析出相对应的目标车载功能配置信息，则表明当前车载控制器需要执行功能更新操作，此时可以基于解析出的与当前车载控制器相匹配的目标车载功能配置信息，对当前车载控制器进行功能更新。若当前车载控制器无法解析出相对应的目标车载功能配置信息，则表明当前车载控制器不需要进行功能更新，此时可以不执行功能更新操作，从而可以仅对需要功能更新的车载控制器进行更新，避免产生更新错误的情况，从而可以保证功能更新的准确性，同时也可以提高控制器功能更新的灵活性。
本申请实施例的技术方案，通过服务器基于预设报文生成方式和待修改功能的至少一个目标控制器对应的目标功能配置信息生成至少一个目标功能报文，并将至少一个目标功能报文发送至车辆，车辆中的网关控制器接收到服务器发送的至少一个目标功能报文，并将接收到的至少一个目标功能报文向至少一个车载控制器进行广播，以使车辆中的至少一个车载控制器接收到至少一个目标功能报文。每个车载控制器可以基于与预设报文生成方式相匹配的预设报文解析方式，对接收到的至少一个目标功能报文进行解析，若存在解析出的与当前车载控制器相匹配的目标车载功能配置信息，则表明需要对当前车载控制器进行更新，此时可以基于目标车载功能配置信息对当前车载控制器进行功能更新，从而可以同时对多个控制器进行功能更新，实现控制器功能的动态更新，并且通过特定的报文生成方式和报文解析方式可以保证功能更新的准确性，同时也提高了控制器功能更新的灵活性和更新效率。
在上述技术方案的基础上，在S120中的“将接收到的至少一个目标功能报文进行广播”之前，还可以包括：基于与预设报文生成方式相匹配的预设报文解析方式，对接收到的至少一个目标功能报文进行解析，并基于解析出的与网关控制器相匹配的目标网关功能配置信息，对网关控制器进行功能更新。
在将接收到的至少一个目标功能报文进行广播之前，网关控制器可以基于与预设报文生成方式相匹配的预设报文解析方式，对接收到的至少一个目标功能报文进行解析，并基于解析出的与网关控制器相匹配的目标网关功能配置信息，对网关控制器进行功能更新，从而实现了网关控制器功能的动态更新，以便后续通过功能更新后的网关控制器，对车载控制器进行功能更新，保证了功能更新的准确性。
网关控制器对接收到的至少一个目标功能报文进行解析的过程和每个车载控制器对接收到的至少一个目标功能报文进行解析的过程相同，可以参照下面实施例的相关描述。
实施例二
图2是本申请实施例二提供的一种控制器功能更新方法的流程图。本实施例在上述实施例的基础上，对步骤“基于与预设报文生成方式相匹配的预设报文解析方式，对接收到的至少一个目标功能报文进行解析”进行了说明。其中与上述本申请实施例相同或相应的术语的解释在此不再赘述。如图2所示，控制器功能更新方法可以包括如下步骤：
S210、通过车辆中的网关控制器，接收服务器发送的至少一个目标功能报文。

S220、通过网关控制器，将接收到的至少一个目标功能报文进行广播，以使车辆中的至少一个车载控制器接收到至少一个目标功能报文。
S230、通过每个车载控制器，获取接收到的每个目标功能报文中的目标报文标识信息。
目标报文标识信息可以指目标功能报文对应的唯一标识信息，以便区分出不同的目标功能报文。目标报文标识信息可以是指根据预设报文生成方式生成的用于与车载控制器进行匹配的信息。目标报文标识信息可以利用数字和/或字母等方式进行表征。例如，目标报文标识信息SN(即报文顺序号)可以为1。
每个车载控制器对应的报文解析方式相同，本实施例以当前车载控制器对功能报文的解析方式为例进行说明。当前车载控制器对接收到的每个目标功能报文进行解析，获得每个目标功能报文中的目标报文标识信息。
S240、将每个目标报文标识信息与当前车载控制器对应的预设需求报文标识信息进行匹配，并将匹配成功的目标报文标识信息所对应的目标功能报文作为目标车载功能报文。
当前车载控制器对应的预设需求报文标识信息可以是指预先设定的当前车载控制器功能更新所需要的功能报文对应的标识信息。预设需求报文标识信息的数量可以为一个或多个。
当前车载控制器将每个目标功能报文中的目标报文标识信息与当前车载控制器对应的预设需求报文标识信息进行匹配，若一个目标报文标识信息与当前车载控制器对应的任意一个预设需求报文标识信息匹配成功，则表明该目标功能报文是当前车载控制器所需要的，此时可以将该目标功能报文作为目标车载功能报文。例如目标报文标识信息SN为1，且当前车载控制器对应的预设需求报文标识信息包括SN为1，SN为3等信息，则可以将SN为1的目标功能报文作为目标车载功能报文。其中，确定出的目标车载功能报文的数量可以为一个或多个。若一个目标报文标识信息与当前车载控制器对应的所有预设需求报文标识信息不匹配，则表明该目标报文标识信息所对应的目标功能报文不是当前车载控制器所需要更新的功能报文，从而通过匹配筛选可以保证功能更新的准确性。
S250、基于目标车载功能报文中的掩码字节对应的目标掩码字节数值，确定目标车载功能报文中处于有效状态的目标功能字节。
掩码字节可以用于存储掩码字节数值。例如掩码字节可以是表1中的Mask。目标掩码字节数值可以是目标掩码字节对应的一个十六进制的数值。例如目标掩码字节数值可以是表1中Mask所代表的数值。目标掩码字节数值可以设置为0x08(十六进制，对应的二进制数为00001000)。目标掩码字节数值可以用于表征所对应的车载功能报文中处于有效状态的目标功能字节。有效状态可以是指使能状态。反之无效状态可以是指不使能状态。目标功能字节可以用于存储控制器功能更新的信息。每个目标功能字节可以对应一个控制功能。例如每个功能字节可以是表1中C1至C6中的任意一个。若存在超过预设数量的控制功能需要更新，则控制功能对应的目标功能字节需要存储在至少一条目标车载功能报文中。目标车载功能报文中处于有效状态的目标功能字节的数量可以为一个，也可以为多个。
针对每个目标车载功能报文而言，基于该目标车载功能报文中的掩码字节对应的目标掩码字节数值，可以确定该目标车载功能报文中处于有效状态的目标功能字节，以便仅对有效状态的功能字节进行分析处理，无需对无效状态的功能字节进行分析处理，即无论功能字节对应的功能字节数值是任意值，只要功能字节被确定为无效状态，那么目标车载控制器不会基于无效状态的功能字节对应的目标车载功能配置信息进行功能更新，从而可以只关注有效状态的目标功能字节，无需关注无效状态的目标功能字节，进而可以避 免因无效状态的功能字节设置错误所导致的功能更新错误的情况，在节约控制器功能更新资源的同时，提高功能更新的效率和准确性。
S260、基于目标车载功能报文中的目标功能字节对应的目标功能字节数值，确定与当前车载控制器相匹配的目标车载功能配置信息。
目标功能字节数值可以是预先配置的目标掩码字节对应的一个十六进制的数值。例如目标功能字节数值可以是表1中C1至C6中任意一个所代表的数值。目标功能字节数值可以设置为0x01(十六进制，对应的二进制数为00000001)。
当前车载控制器基于每个目标车载功能报文中的目标功能字节对应的目标功能字节数值可以确定出待配置的多个车载功能信息，并对多个车载功能信息进行组合，获得与当前车载控制器相匹配的目标车载功能配置信息，从而保证功能更新的准确性。
S270、基于解析出的与当前车载控制器相匹配的目标车载功能配置信息，对当前车载控制器进行功能更新。
本申请实施例的技术方案，基于该目标车载功能报文中的掩码字节对应的目标掩码字节数值，可以确定该目标车载功能报文中处于有效状态的目标功能字节，以便仅对有效状态的功能字节进行分析处理，无需对无效状态的功能字节进行分析处理，即无论功能字节对应的功能字节数值是任意值，只要功能字节为被确定为无效状态，那么目标车载控制器不会基于无效状态的功能字节对应的目标车载功能配置信息进行功能更新，从而可以只关注有效状态的目标功能字节，无需关注无效状态的目标功能字节，进而可以避免因无效状态的功能字节设置错误所导致的功能更新错误的情况，在节约控制器功能更新资源的同时，提高功能更新的效率和准确性。
在上述技术方案的基础上，S250中的“基于目标车载功能报文中的掩码字节对应的目标掩码字节数值，确定目标车载功能报文中处于有效状态的目标功能字节”可以包括：基于目标车载功能报文中的掩码字节对应的目标掩码字节数值，获取掩码字节中的每个二进制位对应的目标二进制数值；基于掩码字节中的每个二进制位对应的二进制数值与功能字节状态之间的对应关系以及掩码字节中的每个二进制位对应的目标二进制数值，确定目标车载功能报文中处于有效状态的目标功能字节。
二进制数值与功能字节状态之间的对应关系可以是预先基于业务需求进行配置获得的。该对应关系可以是二进制数值为1对应功能字节的有效状态；二进制数值为0对应功能字节的无效状态。掩码字节可以用于存储掩码字节 数值。例如掩码字节可以是表1中的Mask。目标掩码字节数值可以是目标掩码字节对应的一个十六进制的数值。例如目标掩码字节数值可以是表1中Mask所代表的数值。目标掩码字节数值可以设置为0x08(十六进制，对应的二进制数为00001000)。目标掩码字节数值可以用于表征所对应的车载功能报文中处于有效状态的目标功能字节。例如，目标掩码字节数值对应的二进制数中的前两个二进制位可以为预留位，其余的6个二进制位可以分别表示相应的功能字节是否为有效状态。例如，表2给出了一种二进制数值与功能字节状态之间的对应关系的示例。表2中的C1至C6可以是指6个功能字节。若目标掩码字节数值为0x08(十六进制)，则需要先将数值从十六进制转化为8位二进制数，即0x08转化后的二进制数为00001000(从左至右为位7至位0)。目标控制器可以基于转化后得到的二进制数获得每个二进制位对应的二进制数值，并可以基于转化后的二进制数与每个二进制位对应的二进制数值确定目标车载功能报文中处于有效状态的目标功能字节，即C2为有效，其余均无效，故该控制器只对自身C2中数据进行更新。
表2 二进制数值与功能字节状态之间的对应关系

基于目标车载功能报文中的掩码字节对应的目标掩码字节数值，获取掩码字节中的每个二进制位对应的目标二进制数值，并基于掩码字节中的每个二进制位对应的二进制数值与功能字节状态之间的对应关系以及掩码字节中的每个二进制位对应的目标二进制数值，确定目标车载功能报文中处于有效状态的目标功能字节，例如，可以将目标二进制数值为1所对应的功能字节确定为处于有效状态的目标功能字节，从而利用掩码字节数值可以准确控制每个功能字节的有效性。
在上述技术方案的基础上，S260中的“基于目标车载功能报文中的目标功能字节对应的目标功能字节数值，确定与当前车载控制器相匹配的目标车载功能配置信息”可以包括：基于目标车载功能报文中的目标功能字节对应的目标功能字节数值，获取目标功能字节中的每个二进制位对应的目标二进制数值；若存在至少两个预设需求报文标识信息，基于目标报文标识信息和每个预设需求报文标识信息下的目标功能字节中的二进制数值与功能状态信息之间的对应关系，确定目标报文标识信息下的目标功能字节中的二进制数值与功能状态信息之间的目标对应关系；基于二进制数值与功能状态信息之间的目标对应关系以及目标功能字节中的每个二进制位对应的目标二进制数值，确定与当前车载控制器相匹配的目标车载功能配置信息。
例如，表3给出了第一个目标功能字节C1对应的二进制数值与功能状态信息之间的目标对应关系的示例。表4给出了第二个目标功能字节C2对应的二进制数值与功能状态信息之间的目标对应关系的示例。
表3 C1对应的二进制数值与功能状态信息之间的目标对应关系

表4 C2对应的二进制数值与功能状态信息之间的目标对应关系
若目标功能字节C1对应的目标功能字节数值为0x01(十六进制)，则目标功能字节C1所对应的目标功能字节数值转化为二进制数值为00000001，并对应表3中位1-0中的功能状态信息为“1.8T”。若目标功能字节C2也为0x01，则目标功能字节C2所对应的二进制数值也为00000001，但对应表4中位0中的功能状态信息为“AQS开”。
例如，表4中空调控制器定义发动机型号是为了配置制冷能力的标定参数，同时配置AQS功能开闭。表3中转向控制器定义发动机型号是为了配置不同排量发动机对应的转向力矩。预先设定的空调控制器需要接收如表1中功能报文的SN(值为2)、Mask、C1(位1-0)、C2(位0)四个字节的信息，转向控制器需要接收如表1中功能报文的SN(值为2)、Mask、C1(位 1-0)三个字节的信息。若用户后续购买了AQS功能，那只需发送0x500的功能报文，其中，SN设置为2，Mask设置为0x08(十六进制，对应的位7-位0的值为00001000)，C2设置为0x01(十六进制，对应的位7-位0的值为00000001，假设其他位是预留的)，从而不论C1、C3-C6字节无论设置何值，即使C1中发动机排量不小心设置错误了，也不会影响单独修改AQS功能的开启。同样的，若用户要单独修改发动机排量的配置，并将发动机排量改到2.0的配置，则只需将Mask设置为0x04(十六进制，对应的位7-位0的值为00000100)，C2设置为0x02(十六进制，对应的位7-位0的值为00000010，假设其他位是预留的)，从而可以同时修改空调控制器和转向控制器中关于发动机排量的配置，即实现控制器的动态更新，进而保证功能更新的准确性，同时也可以提高控制器功能更新的灵活性。
由于车辆控制器配置功能非常多，SN可以从1定义到255。通过上述方案，目标控制器只基于指定的需求报文标识信息、指定的控制功能与掩码字节数值的映射关系以及实际发送的掩码字节对应的数值来是实现目标控制器功能更新，从而保证功能更新的准确性。
当前车载控制器基于目标车载功能报文中的目标功能字节C2对应的目标功能字节数值00000001，获取目标功能字节C2中的每个二进制位对应的目标二进制数值，即将00000001与位7至位0一一对应，对应结果为位7至位1都对应0，只有位0对应1。若存在至少两个预设需求报文标识信息，则表明当前控制器中可以存在至少两个与目标功能报文标识信息进行匹配的预设需求报文标识信息，并基于目标报文标识信息和每个预设需求报文标识信息下的目标功能字节中的二进制数值与功能状态信息之间的对应关系，确定目标报文标识信息下的目标功能字节中的二进制数值与功能状态信息之间的目标对应关系，比如表3和表4。基于二进制数值与功能状态信息之间的目标对应关系以及目标功能字节中的每个二进制位对应的目标二进制数值，确定与当前车载控制器相匹配的目标车载功能配置信息，从而可以同时对多个控制器进行功能更新，实现控制器功能的动态更新，并且通过特定的报文生成方式和报文解析方式保证功能更新的准确性，并提高了控制器功能更新效率。
