Description

一种检测车辆发电机的方法及电池检测仪

技术领域
本申请涉及车辆诊断技术领域，特别涉及一种检测车辆发电机的方法及电池检测仪。
背景技术
影响车辆启动的核心部分是电池(也称蓄电池)、起动机(starter)和发电机(generator)，当任何一个部件出现问题，都将导致车辆不能工作。其中，车辆发电机是车辆的主要电源，其功用是在发动机(engine)正常运转时，向所有用电设备(起动机除外)供电，同时向蓄电池充电。
车辆发电机的功能是否正常一般需要检查电池的几个能力：输出电压的能力、输出电流的能力、纹波控制能力。电压、电流输出过高或者过低，表示发电机的调节器出了问题；纹波过大，一般表示发电机的控制二极管出现异常，将会导致输出信号不能保证电器正常工作。由于发电机处于车辆内部，用户不易接触，用户一般通过车辆电池检测仪检测电池的输出电压、输出电流和纹波来判定发电机的好坏。

此外，下面所描述的本发明各个实施方式中所涉及到的技术特征只要彼此之间未构成冲突就可以相互组合。
请参见图1，其示出了本发明实施例提供的检测车辆发电机的方法的其中一种应用环境的示意图，该应用环境中包括：车辆10和电池检测仪20，车辆10包括电池，所述电池检测仪20通过开尔文连接器与车辆10的电池连接，且所述电池检测仪20通过所述车辆10的OBD接口与所述车辆10通信连接， 通信连接方式可以为有线连接或无线连接。
所述车辆10是一种由多个ECU(Electronic Control Unit，电子控制单元)组成的电子控制系统，用以协调和控制车辆按照驾驶员等的操作指令，并对一个或者多项车辆参数进行实时监测，确保车辆10可靠并安全地运行。可以理解的是，在不同车型或者车款的车辆中，根据其结构设置和承担功能的区别，所具有的ECU数量或类型是不相同的。
所述车辆10中的各个ECU之间通常采用总线的方式实现通信连接。每个ECU使用特定的通信协议。ECU按照自身使用的通信协议，会在相应的汽车总线上进行通信，以避免冲突和提升效率。亦即，使用同一种通信协议的ECU在一种汽车总线上通信，一种汽车总线与一种通信协议对应。由于所述通信协议与所述车辆10的车型相关，因此，可以通过获取车辆10的车辆信息来获取车辆10的通信协议，其中，所述车辆信息包括VIN码(Vehicle Identification Number，车辆识别号码/车架号)和/或MMY码(Make、Model、Year，车辆制造商、年款和车型)。
为了便于日常检修和维护，车辆10还可以具有至少一个硬件通信接口，例如OBD(On-Board Diagnostics)接口。该硬件通信接口与车辆10可以与一种或者多个汽车总线连接，用于与外部设备建立通信连接，使其与ECU完成数据交互等过程。例如，车辆10通过OBD接口与电池检测仪20建立起通信连接，电池检测仪20能够获取来自车辆10的数据信息，例如车辆信息等。

在实际使用过程中，首先将电池检测仪20的测量夹子连接在车辆电池的正负极，将电流钳夹子车辆的电池的负极线上。电池检测仪20通过接口模块，例如诊断接口和硬件通信接口，与车辆10中的多种汽车总线建立物理上的通信连接，并加载合适或者配对的协议配置来实现与电子控制系统之间的数据交互，例如发送指令或者接收数据，可根据实际需要对从所述车辆10和所述电池检测仪20的进行选择和设置，不需要拘泥于本应用场景的限定。
具体地，下面结合附图，对本发明实施例作进一步阐述。
实施例一
本发明实施例提供了一种检测车辆发电机的方法，应用于电池检测仪，所述电池检测仪可以是上述应用场景所述的电池检测仪20，所述电池检测仪通过开尔文连接器与车辆的电池连接，且所述电池检测仪通过所述车辆的OBD接口与所述车辆通信连接，请参见图2，其示出了本发明实施例提供的一种检测车辆发电机的方法的流程，所述方法包括但不限于以下步骤：
步骤101：提示用户启动所述车辆的发动机。
首先，通过图像、文字、语音、指示灯等方式提示用户启动所述车辆的发动机，让车辆进入工作状态，以进一步对车辆的电池、起动机和发电机进行进一步地检测。
步骤102：若检测到所述发动机开启，通过所述OBD接口发送第一控制指令以控制所述车辆关闭车辆负载，获取所述电池的第一测量数据。
在检测到发动机启动之后，电池检测仪通过车辆的OBD接口与车辆通信连接，发送能够控制车辆负载关闭的第一控制指令至车辆，同时通过OBD接口获取车辆电池的第一测量数据。其中，对于需要踩至少一脚油门才能进入工作状态的车型的车辆，在发动机启动之后，所检测得到的第一测量数据仅包含了车辆的初始测量数据，要获取车辆的空载测量数据，需要踩油门使得车辆进入工作状态后才能够检测得到，其中，所述初始测量数据可以是电池的纹波等能够表征电池工作状态的特征波形，具体地，可通过带通滤波器，过滤掉0-3000Hz的信号，并从该信号线上读取纹波的副值变化，得到纹波数据。对于已经进行智能化管理，不需要踩油门，启动发动机后能够直接进入工作状态的车型的车辆，在发动机启动之后，能够直接检测得到车辆的包含初始测量数据和空载测量数据的第一测量数据，也即是，所述第一测量数据包括但不限于初始测量数据和空载测量数据。
步骤103：通过所述OBD接口发送第二控制指令以控制所述车辆开启所述车辆负载，获取所述电池的第二测量数据。
在获取完第一测量数据后，电池检测仪通过车辆的OBD接口与车辆通信连接，发送能够控制车辆负载打开的第二控制指令至车辆，同时通过OBD接口获取车辆电池的第二测量数据。其中，所述第二测量数据包括但不限于带载测量数据。
在本发明实施例中，所述车辆负载为车辆中的空调、大灯、仪表、音响等大电流电器中的至少一种。所述第一控制指令或所述第二控制指令对应至少一个车辆负载。且有，所述第一控制指令或所述第二控制指令的通信协议与所述车辆的车辆信息相关。所述车辆信息可以是通过VIN码获取，和/或通过MMY码解析获取，也可以是由用户输入的。
步骤104：根据所述第一测量数据和所述第二测量数据，检测所述车辆的发电机的状态。
在获取到所述第一测量数据和所述第二测量数据后，即可至少得到电流的带载测量数据和空载测量数据，以及纹波等测量数据，通过判断所述测量数据是否在预设范围内，即可确定所述发电机是否处于正常工作的状态/是否故障。
在现有的车辆发电机的检测方法中，需要用户手动控制车辆负载的打开或关闭，并在打开或关闭所述车辆负载后手动输入确定车辆负载已打开或已关闭的操作，而区别于现有的车辆发电机的检测方法，在本发明实施例所提供检测方法中，车辆负载由电池检测仪控制打开和关闭，能够有效减少用户手动操作 的步骤，节省了用户的时间，同时提高检测结果的有效性和准确性。
在一些实施例中，如上述步骤102所述，存在部分车型的车辆需要至少踩一脚油门才能够启动，进入工作状态的情况，此时，所述第一测量数据包括初始测量数据，在步骤102和步骤103之间，请参见图3，其示出了本发明实施例提供的另一种检测车辆发电机的方法的流程，所述方法还包括：
步骤105：提示用户启动油门以提高所述发动机转速，获取所述电池的空载测量数据。
首先，在获取完所述第一测量数据，也即是得到初始测量数据如电池的纹波之后，发送提示信息给用户，以提示用户启动油门(即脚踩油门)以提高发动机的转速，从而使得车辆进入工作状态，以获取电池的空载测量数据。具体地，请一并参见图4，其示出了步骤105的一子流程，所述步骤105包括：
步骤105a：提示用户启动油门以提高所述发动机转速；
步骤105b：向所述车辆发送读取发动机转速的控制指令；
步骤105c：接收所述车辆根据所述控制指令反馈的发动机转速；
步骤105d：判断所述发动机转速是否大于或等于第一预设阈值；若是，跳转至步骤105e：
步骤105e：获取所述电池的空载测量数据。
在本发明实施例中，根据所处车辆的发动机的转速是否达到第一预设阈值来判断所述车辆是否进入工作状态，在确定所述车辆进入工作状态，即在车辆除车辆负载外的器件能够正常工作时，获取电池的空载测量数据。
例如，当所述第一预设阈值为2000转时，通过标准检测协议SAE J1979发送十六进制的OBD控制指令01 0C读取发动机的转速，车辆在接收到所述控制指令后，反馈相同格式的指令以反馈发动机的转速，具体地，电池检测仪通过接收41 0C xx xx指令来获取发动机的转速，判断所获取到的发动机的转速是否高于2000转，以确定用户是否踩了油门，车辆是否进入了工作状态。其中，第一个xx每个单位表示64转，第二个xx每四个单位代表1转，进而经过计算可以得出发动机的转速，例如，接收到41 0C 01 04时，可得到所述发动机的转速为01*64+04/4＝65转。
本申请实施例中，对于发动机转速信息的获取，如在步骤105b、105c中，可以发送一次读取指令后，实时获取车辆反馈的发动机转速；或者，可以按预设频率发送读取指令，并按照预设频率接收发动机转速。
通过此种方式，电池检测设备可以自动读取发动机的转速，无需用户手动输入，进一步简化了用户操作。
步骤106：提示用户松开油门以降低所述发动机转速。
在得到所述车辆的空载测量数据后，发送提示信息给用户，以提示用户松开油门、降低发动机的转速，从而使得车辆退出工作状态后，跳转至步骤103开启车辆负载以获取电池的第二测量数据。具体地，请一并参见图5，其示出 了步骤106的一子流程，所述步骤106包括：
步骤106a：提示用户松开油门以降低所述发动机转速；
步骤106b：向所述车辆发送读取发动机转速的控制指令；
步骤106c：接收所述车辆根据所述控制指令反馈的发动机转速；
步骤106d：判断所述发动机转速是否小于第二预设阈值；若是，跳转至步骤103。
在本发明实施例中，根据所述车辆的发动机的转速是否低于第二预设阈值来判断所述车辆是否退出工作状态，在确定所述车辆退出工作状态后，打开车辆负载，以获取包含带载测量数据的第二测量数据。其中，所述第二预设阈值小于所述第一预设阈值。
例如，所述第二预设阈值可以设定为1000转，在检测到所述发动机的转速低于1000转时，可以确定用户松开了油门，车辆退出了工作状态。具体地，关于所述控制指令和所述发动机转数的发送和读取方式，可以是上述步骤105及图4所示实施例所述的方式，也可以根据实际车辆的情况进行设置，不需要拘泥于本发明实施例的限定。
在其他的一些实施例中，所述测量发动机转数的步骤，若无法通过如上述OBD指令读取的方式，也可以是通过检测电池变化波纹特性的方式来判断，具体地，发动机运行时，会在车辆上造成一个整体的抖动信号，该抖动信号与发动机的转速成正比，因此通过检测该抖动信号来确定发动机的转速。需要说明的是，通过抖动信号来判断的方式，精确度不如上述优选的通过OBD指令读取的方式。
基于步骤105和步骤106，所述步骤104进一步包括：根据所述第一测量数据，所述空载测量数据和所述第二测量数据，检测所述发电机的状态。
进一步地，在得到所述第一测量数据(初始测量数据)、所述空载测量数据和所述第二测量数据(带载测量数据)后，可以根据上述测量数据判断所述车辆的发电机是否处于正常工作的状态。其中，所述空载测量数据至少包括空载电压和空载电流，所述带载测量数据至少包括带载电压和带载电流。
例如，通常地，在车辆中，当检测到所述带载电压比所述空载电压低0.5V时，确定所述发电机带载能力异常；当检测到所述带载电压和/或所述空载电压高于15V时，确定所述发电机输出电压过高；当检测到所述带载电流和/或所述空载电流不在10-50A的范围内时，确定所述发电机输出电流异常；当检测到所述初始测量数据如纹波高于200mV时，确定所述发电机的纹波异常。
区别于现有技术中直接通过电压信号查看发动机的抖动频率来判断发动机转数的方式，本发明实施例提供的检测方法通过车辆的OBD接口与车辆通信连接，通过OBD指令进行数据交互，能够大大提高检测结果的准确率。
在一些实施例中，请参见图6，其示出了步骤103的一子流程，所述步骤103进一步包括：
步骤103a：通过所述OBD接口发送第二控制指令以控制所述车辆开启所述车辆负载；
步骤103b：提示用户启动油门以提高所述发动机转速；
步骤103c：向所述车辆发送读取发动机转速的控制指令；
步骤103d：接收所述车辆根据所述控制指令反馈的发动机转速；
步骤103e：判断所述发动机转速是否大于或等于第一预设阈值；若是，跳转至步骤103f；
步骤103f：获取所述电池的第二测量数据。
在本发明实施例中，在通过第二控制指令控制车辆开启车辆负载后，发送提示信息给用户，以提示用户启动油门、提高发动机的转速，从而使得车辆进入工作状态，以获取电池的第二测量数据，其中，所述第二测量数据为带载测量数据。具体地，根据所述车辆的发动机的转速是否高于第一预设阈值来判断所述车辆是否进入工作状态，在确定所述车辆进入工作状态后，获取包含带载测量数据的第二测量数据。
例如，所述第一预设阈值可以设定为2000转，在检测到所述发动机的转速达到2000转时，可以确定用户启动了油门，车辆进入了工作状态。具体地，关于所述第二控制指令和所述发动机转数的发送和读取方式，可以是上述步骤105和步骤106及图4和图5所示实施例所述的方式，也可以根据实际车辆的情况进行设置，不需要拘泥于本发明实施例的限定。
在一些实施例中，请参见图7，其示出了本发明实施例提供的另一种检测车辆发电机的方法的流程，在所述步骤103之后，所述方法还包括：
步骤107：提示用户松开油门以降低所述发动机转速直至所述发动机转速小于第二预设阈值。
在本发明实施例中，在检测完所述第二测量数据后，发送提示信息提示用户可以松开油门，检测流程结束，且为了确认用户是否确实松开了油门，所述电池检测仪检测所述发动机转数，在确定所述发动机转数小于第二预设阈值时，可以确定用户松开了油门，检测结束，进一步地，输出检测结果。具体地，关于所述发动机转数的发送和读取方式，可以是上述步骤105、步骤106和步骤103及图4、图5和图6所示实施例所述的方式，也可以根据实际车辆的情况进行设置，不需要拘泥于本发明实施例的限定。
在一些实施例中，请参见图8，其示出了本发明实施例提供的另一种检测车辆发电机的方法的流程，在所述步骤101之后，所述方法还包括：
步骤108：监测所述电池的电压以检测所述发动机是否启动。
在本发明实施例中，为确定提示用户启动发动机后，用户是否准确启动了发动机，和/或发动机是否能够正常启动，在执行步骤101之后，所述电池检测仪还需要检测电池的电压以确定所述发动机是否正常启动。请一并参见图 9，其示出了发动机启动的特征波形图，监测所述电池的电压时，若所述电池电压的曲线如图9所示，和/或，所述电池电压如图9所示启动时间范围内，能够骤降至如图9所示启动电压附近和/或骤降幅度如图9所示，则能够确定所述发动机正常启动了。例如，当电压在1ms内下降了0.5V以上，且持续快速下降，则可以确定汽车启动了。
在现有的车辆发电机的检测方法中，需要用户手动输入发动机是否启动，而区别于现有的检测方法，本发明实施例通过步骤108所述的方式，无需用户手动输入发动机是否启动。现实中用户手动确认发动机是否启动需要用户具有一定的驾车经验，或者需要用户参照说明书比对车辆现象确认发动机是否启动，有可能出现用户经验不足导致误确认发动机已启动的情况，进而导致后续检测结果不准确。而在本发明实施例中，电池检测仪可以自动确定发动机是否正常启动，简化了用户操作步骤，提高检测效率的同时增加了确认精度。
