相关申请的交叉引用
本公开要求在2021年06月25日提交中国专利局、申请号为202110711301.5、名称为“发动机的控制方法和装置”的中国专利申请的优先权，其全部内容通过引用结合在本公开中。
本公开涉及车辆控制领域，尤其涉及一种发动机的控制方法、装置、设备、程序和存储介质。
随着社会的不断发展，汽车的保有量也变得越来越高，车辆的运行性能也越来越受到人们的关注，而发动机的运行性能是车辆稳定运行的关键。通常情况下，发动机活塞与缸筒内壁之间会存在窜气现象，因此发动机中通常会设置曲轴箱强制通风系统。
在非增压发动机和增压发动机的非增压区域的曲轴箱强制通风系统中，窜入曲轴箱的气体会流向发动机的进气歧管。在低温环境下进气歧管温度较低，温度较高的气体进入进气歧管遇冷会凝结成水珠，并经由管路流到节气门的位置。在车辆停止且熄火后，经过长时间静置(如晚上长时间停车)，车辆整体温度会降至环境温度，随着温度降低，凝结的水珠会冷凝成冰。在发动机启动之后，节气门会进行破冰，但是破冰之后产生的小冰块，在节气门的开度较小时，仍会卡住节气门，导致节气门驱动电机发生堵转。由于发生堵转时节气门驱动电机的温度会升高，因而会使节气门驱动电机损坏或者上报故障，影响了车辆的正常行驶。

下面参考附图描述本公开实施例的发动机的控制方法、装置、设备、程序和存储介质。
图1是根据一示例性实施例示出的一种发动机的控制方法的流程图，如图1所示，应用于车辆的发动机，该方法包括：
步骤101，检测发动机的节气门所在的管路是否结冰。
举例来说，本公开的应用场景可以为非增压发动机或者增压发动机的非增压区域(即增压器不工作的场景)。车辆在低温环境下静置较长时间之后，节气门所在的管路可能会结冰，发动机在启动时会利用破冰技术将节气门处的冰块打碎。随着发动机内部的温度升高，冰的硬度降低并且伴随融化出现状态变化，贴在节气门管壁上。如果发动机在启动之后一直维持怠速状态，随着发动机的运行时间变长，维持发动机运转的进气量需求降低，节气门需要减小开度，当节气门的阀板与节气门所在的管路的管壁之间的距离减小时，附着在管壁上的冰会容易卡住节气门的阀板，使得节气门的开度无法减小，导致节气门驱动电机发生堵转。由于发生堵转时节气门驱动电机的温度会升高，因而会使节气门驱动电机损坏或者上报故障，影响了车辆的正常行驶。因此在启动发动机之后，首先可以检测发动机的节气门所在的管路是否结冰。具体的，可以通过检测车辆是否满足预设的结冰条件，来确定节气门所在的管路是否结冰，其中，结冰条件例如可以包括：车辆的挡位为预设的档位，发动机和车辆周围的环境温度小于预设的温度阈值等。
步骤102，若检测到节气门所在的管路结冰，根据发动机的当前怠速转速，确定目标怠速转速，目标怠速转速大于当前怠速转速。
步骤103，根据目标怠速转速，增大发动机的节气门的开度，以使发动机产生的热量加热节气门所在的管路。
进一步的，由于可以通过控制节气门的开度来控制目标怠速转速，因此在检测到节气门所在的管路结冰的情况下，可以发出增大发动机的目标怠速转速的指令，以增大节气门的开度，从而使增大后的节气门的开度，能够使发动机达到目标怠速转速。具体的，可以先获取发动机的当前怠速转速，并在当前怠速转速的基础上增加预设的转速值，得到大于当前怠速转速的目标怠速转速。之后，可以根据得到的目标怠速转速，对应增大发动机的节气门开度，使得发动机产生的热量能够通过节气门，加热节气门所在的管路，从而融化节气门所在管路的冰，避免了由于节气门被冰卡住，节气门驱动电机无法控制节气门的开度减小，而导致节气门驱动电机损坏或者上报故障的问题。
综上所述，本公开首先检测发动机的节气门所在的管路是否结冰，在检测到节气门所在的管路结冰的情况下，根据发动机的当前怠速转速，确定目标怠速转速，之后根据 目标怠速转速，增大发动机的节气门的开度，使得发动机产生的热量加热节气门所在的管路。其中，目标怠速转速大于当前怠速转速。本公开通过增大发动机的目标怠速转速来增大节气门的开度，使得发动机产生的热量能够加热节气门所在的管路，从而融化节气门所在的管路的冰，避免了因节气门所在的管路结冰而导致节气门驱动电机发生堵转的问题。
在一种应用场景中，步骤101的一种实现方式为：
若车辆满足预设的结冰条件，确定节气门所在的管路结冰，结冰条件包括：
车辆的挡位为空挡。
发动机的冷却液温度小于或等于预设的第一温度阈值。
车辆周围的环境温度小于或等于预设的第二温度阈值。
发动机的冷却液温度传感器和车辆的环境温度传感器的状态均为正常。
发动机的节气门驱动电机按照指定占空比运行的时长，大于预设的第一时长阈值，指定占空比大于预设的占空比阈值，节气门驱动电机为控制节气门的开度的电机。
示例的，可以通过检测车辆是否满足预设的结冰条件，来确定节气门所在的管路是否结冰。其中，结冰条件可以包括：车辆的挡位为空挡，发动机的冷却液温度小于或等于预设的第一温度阈值，车辆周围的环境温度小于或等于预设的第二温度阈值，发动机的冷却液温度传感器和车辆的环境温度传感器的状态均为正常，发动机的节气门驱动电机按照指定占空比运行的时长，大于预设的第一时长阈值。其中，第一温度阈值例如可以为-10℃，第二温度阈值例如可以为-10℃，占空比阈值例如可以为80％，第一时长阈值例如可以为2s，节气门驱动电机为控制节气门的开度的电机。
需要说明的是，当发动机启动一段时间后，维持发动机怠速运转所需的进气量变小，此时需要减小节气门开度。通常情况下，发动机的节气门驱动电机按照指定占空比(如85％)运行指定时长(如300ms)，就可以控制发动机节气门的开度从最大变为最小。如果发动机的节气门驱动电机按照指定占空比(如85％)运行的时长大于第一时长阈值(如2s)，表明节气门处被冰堵塞，导致节气门驱动电机无法控制节气门开度变小。其中，第一时长阈值大于指定时长。
也就是说，如果车辆的挡位为空挡(车辆此时为停止状态)，且发动机的冷却液温度小于或等于第一温度阈值，且车辆周围的环境温度小于或等于第二温度阈值，且发动机的冷却液温度传感器和车辆的环境温度传感器的状态均为正常，且发动机的节气门驱动 电机按照指定占空比运行的时长，大于第一时长阈值，那么可以确定节气门所在的管路结冰。
在另一种应用场景中，步骤102的一种实现方式为：
根据当前怠速转速和预设的转速步进值，确定目标怠速转速。
示例的，在检测到节气门所在的管路结冰的情况下，可以在发动机的当前怠速转速的基础上，增加转速步进值，得到目标怠速转速，即：将当前怠速转速与转速步进值之和作为目标怠速转速。其中，转速步进值例如可以为100rpm。
图2是根据一示例性实施例示出的另一种发动机的控制方法的流程图，如图2所示，该方法还包括：
步骤104，重复执行步骤101至步骤103的步骤，直至车辆不满足结冰条件，或目标怠速转速大于最大怠速转速，持续按照目标怠速转速，控制发动机的节气门的开度。
示例的，可以重复执行步骤101至步骤103，在检测到发动机的节气门所在的管路结冰的情况下，不断增大目标怠速转速，直到车辆不再满足结冰条件，或目标怠速转速大于最大怠速转速，其中，最大怠速转速例如可以为1800rpm。若目标怠速转速大于最大怠速转速，可以将目标怠速转速确定为最大怠速转速，并持续按照目标怠速转速，控制发动机的节气门的开度。若车辆不再满足结冰条件，那么保持当前的目标怠速转速，并持续按照目标怠速转速，控制发动机的节气门的开度。这样，通过不断增大目标怠速转速，使得节气门的开度增大，发动机的输出功率不断增大，相应的，发动机产生的热量也不断增大，因此节气门所在的管路的冰能够被发动机产生的热量融化，避免了由于节气门被冰卡住，节气门驱动电机无法控制节气门的开度减小，而导致节气门驱动电机损坏或者上报故障的问题。同时，通过逐渐增大目标怠速转速的方式来增大节气门的开度，能够在保证节气门所在的管路的冰融化的情况下，降低发动机的能耗。
具体的，以当前怠速转速为1200rpm，最大怠速转速为1800rpm，每次循环增加的转速为100rpm为例，如果循环执行3次之后，车辆不再满足结冰条件，那么可以保持1500rpm的目标怠速转速，并持续按照1500rpm的目标怠速转速，控制发动机的节气门的开度。或者当循环执行超过6次之后，目标怠速转速大于1800rpm，那么可以保持1800rpm的目标怠速转速，并持续按照1800rpm的目标怠速转速，控制发动机的节气门的开度。
图3是根据一示例性实施例示出的另一种发动机的控制方法的流程图，如图3所示， 该方法还包括：
步骤105，若车辆满足预设的退出条件，将目标怠速转速设置为基础怠速转速，基础怠速转速为，发动机在正常怠速状态下对应的转速。
退出条件包括以下至少一种：
发动机按照怠速运行的时长大于预设的第二时长阈值。
车辆的油门踏板开度大于预设的开度阈值。
车辆的车速大于预设的车速阈值。
车辆的挡位不为空挡。
发动机的冷却液温度传感器的状态为异常。
车辆的环境温度传感器的状态为异常。
示例的，在重复执行步骤101至步骤103的过程中，可以实时检测车辆是否满足预设的退出条件。其中，退出条件可以包括以下至少一种：发动机按照怠速运行的时长大于预设的第二时长阈值。车辆的油门踏板开度大于预设的开度阈值。车辆的车速大于预设的车速阈值。车辆的挡位不为空挡。发动机的冷却液温度传感器的状态为异常。车辆的环境温度传感器的状态为异常。其中，第二时长阈值例如可以为180s，开度阈值例如可以为5％，车速阈值例如可以为5km/h。
需要说明的是，当车辆的油门踏板开度大于预设的开度阈值，或者车辆的车速大于预设的车速阈值，或者车辆的挡位不为空挡时，表明车辆已经开动(即车辆不为停止状态)，此时，发动机所需的进气量较大，相应的，节气门的开度也较大，因此不用继续通过执行步骤101至103的步骤，来增大节气门的开度。
也就是说，当上述条件至少有一种满足时，表明节气门所在的管路的冰已经融化，或者检测装置发生异常，那么可以确定车辆满足退出条件。此时可以将目标怠速转速设置为基础怠速转速，使得车辆能够以维持发动机稳定运转的最低怠速转速运行。其中，基础怠速转速可以理解为，发动机在正常怠速状态下对应的转速。
具体的，以第二时长阈值为180s，开度阈值为5％，车速阈值为5km/h为例，当发动机按照怠速运行的时长大于180s时，或者当油门踏板开度大于5％时，或者当车速大于5km/h时，可以确定车辆满足退出条件，并控制发动机按照为基础怠速转速运转。
综上所述，本公开首先检测发动机的节气门所在的管路是否结冰，在检测到节气门所在的管路结冰的情况下，根据发动机的当前怠速转速，确定目标怠速转速，之后根据 目标怠速转速，增大发动机的节气门的开度，使得发动机产生的热量加热节气门所在的管路。其中，目标怠速转速大于当前怠速转速。本公开通过增大发动机的目标怠速转速来增大节气门的开度，使得发动机产生的热量能够加热节气门所在的管路，从而融化节气门所在的管路的冰，避免了因节气门所在的管路结冰而导致节气门驱动电机发生堵转的问题。
