但是，发动机的工作状态直接关系到机油的降级劣化，显然基于车辆行驶里程确定的机油保养方案，不能及时有效地确定发动机机油是否需要保养。

目前车辆的发动机的多个活动部件需要润滑，发动机耐久性直接和润滑油的润滑能力相关，但是发动机机油润滑能力随时间推移降低，因此，目前发动机的保养一般是通过车辆行驶里程来确定的。但是，发动机的工作状态直接关系到机油的降级劣化，显然基于车辆行驶里程确定的机油保养方案，存在机油润滑性能良好而过度保养的浪费，或是劣化严重而未及时更换的风险，所以现有技术不能及时有效地确定发动机机油是否需要保养。
为了克服上述问题，及时有效地确定发动机机油是否需要保养，本申请实施例提供一种发动机机油保养控制方法，图1为本申请实施例提供的发动机机油保养控制方法的流程示意图。
参见图1，所述发动机机油保养控制方法，包括：
S101、获取发动机实际转速信息。
本实施例中，参考图11，实现发动机机油保养控制方法的执行主体可以是控制器1101，具体可以是车辆上安装的电子控制单元(Electronic Control Unit，ECU)。为了实现发动机机油润滑性能实时掌控，进而实现发动机机油保养的智能精准化的闭环控制，确保发动机始终在优良充分的润滑环境中工作，可以通过进气系统、燃油喷射系统以及曲轴转速传感器实时反馈，即ECU通过实时检测进气系统、燃油喷射系统和曲轴转速传感器，进而获取发动机的实际进气量、实际喷油量和实际转速信息，实现对发动机不同运行工况下的发动机机油情况进行监控，这里的运行工况负荷主要是依据各个转速情况下的发动机喷油量以及进气量确定的。
S102、从多个预设转速区间中确定与所述实际转速信息对应的目标转速区间。
在实际应用中，实际转速信息可以是实时获取的，例如可以获取一段时间内的转速数据。因此，实际转速信息可以包括不同时刻对应的多个转速数据。通过预先划分的多个预设转速区间，可以将实时获取的实际转速信息与多个预设转速区间进行匹配，从多个预设转速区间中查找出与各个转速数据相对应的目标转速区间。其中，ECU根据实时接收的进气系统发送的实际进气量、燃油喷射系统发送的实际喷油量，结合曲轴转速传感器发送的转速信息，综合判断发动机扭矩，计算出发动机的各个运行工况负荷，这里的运行工况负荷可以包括第一小负荷、第一中负荷、第一大负荷、第二小负荷、第二中负荷、第二大负荷中至少一项。其中，多个预设转速区间可以包括预设低转速区间、 预设中低转速区间、预设中高转速区间以及预设高转速区间，由于预设低转速区间的转速较低以及预设高转速区间的转速较高，这两个转速区间对应的工况负荷对机油劣化量的影响较小，可以主要由转速来确定机油劣化系数以及机油劣化量。
S103、根据所述目标转速区间，确定与所述目标转速区间匹配的目标机油劣化系数。
在实际应用中，多个预设转速区间、目标机油劣化系数、运行工况负荷可以存储在一个机油劣化量数据表中。针对每个运行工况负荷，基于机油劣化量数据表，若检测到在机油劣化量数据表中存在与所述运行工况负荷和所述运行工况负荷对应的目标转速区间，则从所述机油劣化量数据表中获取与目标转速区间和运行工况负荷均匹配的目标机油劣化系数。其中，机油劣化量数据表是在发动机机油正常时通过测量获得的多个历史进气量、多个历史转速信息以及多个历史喷油量生成的。
本实施例中，通过进气系统采集并发送的实际进气量、燃油喷射系统采集并发送的实际喷油量和曲轴转速传感器采集并发送的实际转速信息，对发动机不同运行工况下的发动机机油是否需要保养的情况进行监控，这里的运行工况负荷主要是依据各个转速情况下的发动机的实际进气量和实际喷油量来确定的。
具体地，根据获取的实际进气量、实际喷油量和实际转速信息，首先确定该运行工况下的运行工况负荷，通过从预先试验标定的机油劣化量数据表中查找是否存在与运行工况负荷对应的实际转速信息匹配的目标转速区间和与运行工况负荷匹配的目标负荷。如果查找到与各个运行工况负荷对应的实际转速信息匹配的目标转速区间和与运行工况负荷匹配的目标负荷，则说明可以从机油劣化量数据表中获取与各个运行工况负荷对应的目标转速区间和目标负荷均匹配的目标机油劣化系数。
S104、获取与所述目标转速区间对应的所述发动机的累计运转时间。
S105、根据所述目标机油劣化系数、所述累计运转时间以及预设机油劣化量，生成用于提示发动机机油是否需要保养的提示信息。
本实施例中，由于根据进气量、喷油量和转速信息可以对应工况负荷，因此，在确定发动机的实际进气量、实际喷油量和实际转速信息时即可确定该工况下对应的工况负荷。所以，在从机油劣化量数据表中获取与各个运行工况负荷匹配的目标转速区间和目标负荷时，此时，可以确定该工况负荷下的目标机油劣化系数，一个运行工况负荷对应一个机油劣化系数。然后根据获取的各个运行工况负荷对应的累计运转时间，可以确定各个运行工况负荷对应的机油劣化量，再通过与预设机油劣化量进行比对，可以确定发动机机油是否需要保养并生成用于提示发动机机油是否保养的提示信息，能够及时有效地确定何时应当保养发动机机的问题。
本实施例中，通过获取发动机的实际进气量、实际喷油量和实际转速信息，并根据实际进气量、实际喷油量以及实际转速信息，确定发动机的各个运行工况负荷。为了能够及时有效地确定发动机机油是否需要保养，可以针对每个运行工况负荷，基于通过测量获得的多个历史进气量、多个历史转速信息以及多个历史喷油量生成的机油劣化量数据表，检测在机油劣化量数据表中是否存在与运行工况负荷对应的实际转速信息和运行工况负荷分别匹配的目标转速区间和目标负荷。若存在，则从机油劣化量数据表中获取与目标转速区间和目标负荷均匹配的目标机油劣化系数，再根据获取得到的每个运行工况负荷对应的累计运转时间，以及预设机油劣化量，确定发动机机油是否需要保养，进而确保发动机始终在优良充分的润滑环境中工作，并通过生成用于提示发动机机油是否需要保养的提示信息，来及时有效地提醒发动机是否需要保养，避免发动机机油由于劣化严重而未及时更换的风险。
在一种可能的设计中，为了能够及时地提醒用户该车辆是否需要保养发动机机油，在所述生成用于提示发动机机油是否需要保养的提示信息之后，所述方法还包括：
通过车辆仪表显示屏显示所述用于提示发动机机油是否需要保养的提示信息。
或者，在所述生成用于提示发动机机油是否需要保养的提示信息之后，所述方法还包括：
语音播报用于提示发动机机油是否需要保养的提示信息。
本实施例中，通过车辆仪表显示屏显示发动机机油是否需要保养的提示信息，或者通过语音播报用于提示发动机机油是否需要保养的提示信息，能够及时提醒用户发动 机机油是否需要保养。并且该发动机机油是否需要保养的控制或监测是实时的，实现发动机机油油润性能适时掌控，避免了机油油润性能良好而过度保养的浪费，或是机油劣化严重而未及时更换的风险，能够及时确定车辆发动机应当何时需要保养，实现了发动机机油保养的有效控制。
本实施例中，通过接收进气系统发送的实际进气量、燃油喷射系统发送的实际喷油量和曲轴转速传感器发送的转速信息，并根据转速信息以及对应的实际进气量、实际喷油量来确定发动机的运行工况负荷，为了确保发动机始终在优良润滑的环境中工作，通过获取各个运行工况负荷对应的发动机机油劣化系数、每个运行工况负荷对应的累计运行时间以及预设机油劣化量，生成发动机机油是否需要保养的提示信息，并通过车辆仪表显示屏显示用于提示发动机机油是否需要保养的提示信息，能够及时有效地确定发动机的工作状况，进而确定发动机机油是否需要保养。
为了实现发动机机油润滑性能实时掌控，进而实现发动机机油保养智能精准化的闭环控制，确保发动机始终在优良充分的润滑环境中工作，需要进气系统、燃油喷射系统和曲轴转速传感器等实时地反馈，参见图2所示。图2为本申请又一实施例提供的发动机机油保养控制方法的流程示意图，本实施例在上述实施例的基础上，例如，在图1所述的实施例的基础上，对S101方法进行了详细说明。
具体地，ECU获取发动机的实际进气量、实际喷油量和实际转速信息的方式可以为：
S201、获取进气系统实时采集并发送的实际进气量，其中所述进气系统是在接收到用于指示所述进气系统执行进气量采集操作的进气量采集信号后，基于所述进气量采集信号采集得到所述实际进气量；
S202、获取燃油喷射系统实时采集并发送的实际喷油量，其中所述燃油喷射系统是在接收到用于指示所述燃油喷射系统执行喷油量采集操作的喷油量采集信号后，基于所述喷油量采集信号采集得到所述实际喷油量；
S203、获取曲轴转速传感器实时采集并发送的实际转速信息，其中所述曲轴转速传感器是在接收到用于指示所述曲轴转速传感器执行检测转速操作的转速指令后，基于所述转速指令检测得到所述实际转速信息。
本实施例中，转速信息包括转速数据即为转速。具体地，ECU向进气系统下达进气量指令，进气系统负责执行，并将实际进气量回馈至ECU，实现双向闭环精准控制；ECU向燃油喷射系统下达喷油量指令等相关信息，燃油喷射系统同步向ECU反馈具体执行情况，比如将实际喷油量实时反馈给ECU，实现双向闭环精准控制；曲轴转速传感器用于探测发动机的精确转速，并负责将转速数据即时回馈至ECU，用于支持ECU判定发动机工况负荷。通过ECU、进气系统、燃油喷射系统以及曲轴转速传感器的结合，能够实时或适时地检测发动机机油的劣化情况，实现发动机机油润滑性能适时掌控。
在实际应用中，监控发动机机油是否须需要保养的控制方法可以由三种方式实现：
方式一：通过实时监控发动机机油液位。
参见图3，图3为本申请再一实施例提供的发动机机油保养控制方法的流程示意图。本实施例在上述实施例的基础上，例如，在图2所示实施例的基础上，对发动机机油保养控制方法进行了详细说明。在获取发动机的实际进气量、实际喷油量和实际转速信息之前或在所述根据所述目标机油劣化系数、所述累计运转时间以及预设机油劣化量，生成用于提示发动机机油是否需要保养的提示信息之后，所述方法还包括：
S301、获取机油液位传感器采集并发送的实际机油液位数据，其中所述机油液位传感器是在接收到用于指示所述机油液位传感器执行机油液位采集操作的机油液位采集信号后，基于所述机油液位采集信号采集得到的实际机油液位数据；
S302、将所述实际机油液位数据与预设机油液位下限阈值比较，若所述实际机油液位数据低于预设机油液位下限阈值，则确定发动机机油需要保养。
本实施例中，向机油液位传感器发送机油液位采集信号，以使机油液位传感器根据机油液位采集信号采集实际机油液位数据，并将实际机油液位数据实时进行反馈，具体地，机油液位传感器用于检测油底壳1109中机油液面位置，并且能够将液位信息即为机油液位数据传递至ECU，因此，控制器可以在向进气系统发送进气量指令、向燃油 喷射系统发送喷油量指令以及向曲轴转速传感器发送检测发动机的转速指令之前，可以先参考当前的机油液位数据，来预先判断发动机机油是否需要保养。
具体地，首先ECU向机油液位传感器发送机油液位采集信号，机油液位传感器根据机油液位采集信号采集实际机油液位数据，并将实际机油液位数据实时反馈至ECU，ECU配置有预设机油液位下限阈值，通过实际机油液位数据与预设机油液位下限阈值比较，判断发动机机油是否需要保养。若实际机油液位数据低于预设机油液位下限阈值，则确定发动机机油需要保养，可以将发动机机油需要保养的指示信息显示在车辆仪表显示屏上，实时提示用户；若实际机油液位数据低于或是等于预设机油液位下限阈值，则说明发动机机油需要保养，可以将发动机机油需要保养的指示信息显示在车辆仪表显示屏上，提示用户可以去保养发动机机油或是更换发动机机油。
在实际应用中，ECU根据预先多次试验得到的油底壳809储油量的上下刻线，对机油液位数据进行数据处理即为将机油液位数据或对应的油量转换成电信号传递至ECU，然后ECU将处理后的机油液位数据传递至车辆仪表显示屏上，进行显示提醒机油保养与否。
方式二：通过实时监控发动机机油压力。
参见图4，图4为本申请又一实施例提供的发动机机油保养控制方法的流程示意图。本实施例在上述实施例的基础上，例如，在图2所示实施例的基础上，对发动机机油保养控制方法进行了详细说明。在获取发动机的实际进气量、实际喷油量和实际转速信息之前或在所述根据所述目标机油劣化系数、所述累计运转时间以及预设机油劣化量，生成用于提示发动机机油是否需要保养的提示信息之后，所述方法还包括：
S401、获取机油压力传感器采集并发送的实际机油压力数据，其中所述机油压力传感器是在接收到用于指示所述机油压力传感器执行机油压力采集操作的机油压力采集信号后，基于机油压力采集信号采集得到的实际机油压力数据；
S402、将所述实际机油压力数据与预设机油压力下限阈值比较，若所述实际机油压力数据低于预设机油压力下限阈值，则确定发动机机油需要保养。
本实施例中，向机油压力传感器发送机油压力采集信号，以使机油压力传感器根据机油压力采集信号采集实际机油压力数据，并将实际机油压力数据实时进行反馈，具体地，机油压力传感器用于对机油泵1108向发动机提供的机油进行压力适时探测，并且能够将适时机油压力传递至ECU。因此，控制器可以在向进气系统发送进气量指令、向燃油喷射系统发送喷油量指令以及向曲轴转速传感器发送检测发动机的转速指令之前，可以先参考当前的机油压力数据，来预先判断发动机机油是否需要保养。其中，如果方式一中的实际机油液位数据低于或是等于预设机油液位下限阈值，则可以不对方式二的机油压力进行判断，即可直接判断出发动机机油需要保养。
具体地，首先ECU向机油压力传感器发送机油压力采集信号，机油压力传感器根据机油压力采集信号采集实际机油压力数据，并将实际机油压力数据适时反馈至ECU，ECU配置有预设机油压力下限阈值，通过实际机油压力数据与预设机油压力下限阈值比较，判断发动机机油是否需要保养。若实际机油压力数据高于预设机油压力下限阈值，则确定发动机机油不需要保养，可以将发动机机油不需要保养的指示信息显示在车辆仪表显示屏上，实时提示用户；若实际机油压力数据低于或是等于预设机油压力下限阈值，则说明发动机机油需要保养，可以将发动机机油需要保养的指示信息显示在车辆仪表显示屏上，提示用户可以去保养发动机机油或是更换发动机机油。
方式三：通过发动机运行工况对应的发动机机油劣化系数来确定发动机机油是否需要保养。
本实施例中，在确定发动机机油是否需要保养之前，需要先确定发动机机油劣化系数。其中，发动机在各个运行工况下的机油劣化系数可以预先存储在机油劣化量数据表中。因此，机油劣化量数据表的获得可以为：在根据所述目标转速区间，确定与所述目标转速区间匹配的目标机油劣化系数之前，还包括：
获取多个历史进气量、多个历史转速信息以及多个历史喷油量；根据多个历史进气量、多个历史转速信息以及多个历史喷油量，确定发动机的多个历史运行工况负荷；对多个历史转速信息进行转速区间划分，得到多个目标转速区间；根据每个目标转速区间，从多个历史运行工况负荷中确定与每个目标转速区间对应的至少一个目标负荷；为 各个目标负荷匹配对应的目标机油劣化系数；根据多个目标转速区间、每个目标转速区间对应的各个目标负荷以及与各个目标负荷对应的目标机油劣化系数，生成机油劣化量数据表。
其中，一个目标转速区间对应一个或多个目标负荷，一个目标转速区间和一个目标转速区间对应的一个目标负荷对应一个目标劣化系数，所以针对各个目标转速区间，通过各个目标转速区间、各个目标转速区间对应的各个目标负荷、以及与各个目标负荷对应的目标机油劣化系数，可以生成机油劣化量数据表。这里的目标负荷即为运行工况负荷。
在实际应用中，多个目标转速区间包括：第一转速区间、第二转速区间、第三转速区间以及第四转速区间；为各个目标负荷匹配对应的目标机油劣化系数，包括：
第一转速区间(低转速区间)对应的至少一个历史运行工况负荷均为第一负荷，第一负荷为与第一转速区间对应的的目标负荷；第二转速区间对应的至少一个历史运行工况负荷包括第二负荷、第三负荷以及第四负荷；第三转速区间对应的至少一个历史运行工况负荷包括第五负荷、第六负荷以及第七负荷；第四转速区间对应的至少一个历史运行工况负荷为第八负荷，第八负荷为第四转速区间划分得到目标负荷；获取与目标负荷分别匹配的各个目标机油劣化系数。
本实施例中，具体地，多个目标转速区间可以分为低转速区间(即第一转速区间)、中低转速区间(即第二转速区间)、中高转速区间(第三转速区间)以及高转速区间(即第四转速区间)，其中，中低转速区间和中高转速区间分别对应三种运行工况负荷，每种运行工况负荷对应有在该工况下的发动机机油劣化系数以及累计运转时间。
在实际应用中，针对上述三种实现方式的顺序不做限定，可以单独存在，也可以方式一与方式三结合、方式二与方式三结合等等两两结合的方式来判断发动机机油劣化情况。
如何确定与所述目标转速区间匹配的目标机油劣化系数，参见图5所示，图5为本申请另一实施例提供的发动机机油保养控制方法的流程示意图。本实施例在上述实施例的基础上，对S103进行了详细说明。其中，所述多个预设转速区间包括预设低转速区间、预设中低转速区间、预设中高转速区间以及预设高转速区间，所述目标转速区间为所述多个预设转速区间中的一个或多个，所述目标机油劣化系数为多个预设机油劣化系数中的一个。所述根据所述目标转速区间，确定与所述目标转速区间匹配的目标机油劣化系数，包括：
S501、若所述目标转速区间为预设低转速区间，则从所述多个预设机油劣化系数中获取与所述预设低转速区间对应的低转速机油劣化系数，所述低转速机油劣化系数为所述目标机油劣化系数；
S502、若所述目标转速区间为预设中低转速区间，则从所述多个预设机油劣化系数中获取与所述预设中低转速区间对应的中低转速机油劣化系数，所述中低转速机油劣化系数为所述目标机油劣化系数；
S503、若所述目标转速区间为预设中高转速区间，则从所述多个预设机油劣化系数中获取与所述预设中高转速区间对应的中高转速机油劣化系数，所述中高转速机油劣化系数为所述目标机油劣化系数；

本实施例中，根据目标转速区间所属的预设低转速区间、预设中低转速区间、预设中高转速区间以及预设高转速区间中的某一个，不同的转速区间对应有不同的机油劣化系数，将特定的转速区间对应的特定的机油劣化系数作为目标机油劣化系数。比如，若所述目标转速区间为预设低转速区间，则从所述多个预设机油劣化系数中获取的与所述预设低转速区间对应的低转速机油劣化系数为所述目标机油劣化系数；若所述目标转速区间为预设中低转速区间，则从所述多个预设机油劣化系数中获取的与所述预设中低转速区间对应的中低转速机油劣化系数为所述目标机油劣化系数；若所述目标转速区间为预设中高转速区间，则从所述多个预设机油劣化系数中获取的与所述预设中高转速区间对应的中高转速机油劣化系数为所述目标机油劣化系数；若所述目标转 速区间为预设高转速区间，则从所述多个预设机油劣化系数中获取的与所述预设高转速区间对应的高转速机油劣化系数为所述目标机油劣化系数。

其中，将所述发动机在各个运转时间对应运行工况下的机油劣化量进行叠加，得到发动机的实际机油劣化量；将所述实际机油劣化量与所述预设机油劣化量进行比较，若所述实际机油劣化量大于所述预设机油劣化量，则确定发动机机油需要保养，并生成发动机机油需要保养的提示信息。
通过每个运行工况负荷对应的发动机机油劣化系数与每个运行工况负荷对应的累 计运行时间进行乘积运算，得到每个运行工况负荷对应的机油劣质量，再通过实际应用中在发动机机油无需保养的情况下，对发动机机油在每个运行工况负荷对应的发动机机油劣化系数与每个运行工况负荷对应的累计运行时间的乘积之和作为标定量，将运行工况负荷对应的实际机油劣质量与对应的标定量进行比较，若实际机油劣质量大于标定量，则说明发动机机油需要保养，若机油劣质量小于标定量，则说明发动机机油不需要保养，并且将发动机机油是否需要保养的信息生成提示信息，这里提示信息可以包括发动机机油需要保养或发动机机油不需要保养。
在实际应用中，低转速区间和高转速区间均无需确定运行负荷即可确定与低转速区间(第一转速区间)对应的机油劣化系数即为第一机油劣化系数(低转速机油劣化系数)、累计运转时间为第一累计时间发动机在第一累积运转时间对应的运行工况下的机油劣化质量为低转速机油劣化系数*第一累计时间；将第二转速区间对应的发动机的运行工况负荷为第二负荷、第三负荷以及第四负荷即将车辆的发动机的运行工况下针对转速信息将运行工况负荷为对应的第一小负荷、第一中负荷、第一大负荷即为第二负荷、第三负荷以及第四负荷，获取第二负荷对应的机油劣化系数即为第二机油劣化系数(第一中低转速机油劣化系数)和累计运转时间为第二累计时间、第三负荷对应的机油劣化系数即为第三机油劣化系数(第二中低转速机油劣化系数)和累计运转时间为第三累计时间，第四负荷对应的机油劣化系数即为第四机油劣化系数(第三中低转速机油劣化系数)、累计运转时间为第四累计时间，则第一小负荷对应的机油劣化质量为第一中低转速机油劣化系数*第二累计时间、第一中负荷对应的机油劣化质量为第二中低转速机油劣化系数*第三累计时间、第一大负荷对应的机油劣化质量为第三中低转速机油劣化系数*第四累计时间；将第三转速区间对应的发动机的运行工况负荷为第五负荷、第六负荷以及第七负荷即将车辆的发动机的运行工况下针对转速信息将运行工况负荷为对应的第二小负荷、第二中负荷、第二大负荷即为第五负荷、第六负荷以及第七负荷，获取第五负荷对应的机油劣化系数即为第五机油劣化系数(第一中高转速机油劣化系数)和累计运转时间为第五累计时间、第六负荷对应的机油劣化系数即为第六机油劣化系数(第二中高转速机油劣化系数)和累计运转时间为第六累计时间，第七负荷对应的机油劣化系数即为第七机油劣化系数(第三中高转速机油劣化系数)和累计运转时间为第七累计时间，第二小负荷对应的机油劣化质量为第一中高转速机油劣化系数*第五累计时间、第二中负荷对应的机油劣化质量为第二中高转速机油劣化系数*第六累计时间、第二大负荷对应的机油劣化质量为第三中高转速机油劣化系数*第七累计时间；确定与高转速区间(第四转速区间)对应的机油劣化系数即为第八机油劣化系数(高转速机油劣化系数)、累计运转时间为第八累计时间，该运行工况下对应的机油劣化质量为高转速机油劣化系数*第八累计时间。
然后将各个负荷对应的机油劣化量进行累计求和，即总的实际机油劣化量为第一机油劣化系数*第一累计时间+第二机油劣化系数*第二累计时间+…+第八机油劣化系数*第八累计时间。再将总的实际机油劣化量与预设机油劣化量进行比较，若发动机转速若总的实际机油劣化量小于或等于预设机油劣化量，则确定发动机机油不需要保养，并生成发动机机油不需要保养的提示信息；若总的实际机油劣化量大于预设机油劣化量，则确定发动机机油需要保养，并生成发动机机油需要保养的提示信息，实现发动机机油油润性能适时掌控，避免了机油油润性能良好而过度保养的浪费，或是机油劣化严重而未及时更换的风险，能够及时确定车辆发动机应当何时需要保养，实现了发动机机油保养的有效控制。

在实际应用中，ECU累计统计发动机各运行工况负荷、对应运转时间，并与各工况机油劣化系数进行换算求和后，与设定值(预设机油劣化量)进行比较，输出机油保养与否结果(发动机机油需要保养或发动机机油不需要保养)，并传递至车辆仪表显示屏，进行显示并语音提醒机油保养与否。
