具体实施方式Detailed ways

下面将参照附图更详细地描述本发明的示例性实施例。虽然附图中显示了本发明的示例性实施例，然而应当理解，可以以各种形式实现本发明而不应被这里阐述的实施例所限制。Exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention may be embodied in various forms and should not be limited by the embodiments set forth herein.

在对本发明实施例的车辆启动检测方法进行说明之前，首先对车辆的OBD***进行简要说明，OBD***即On-Board Diagnostics***，意为车载自动诊断***，指的是基于计算机***检测车辆主要发动机部件的性能。可以通过DLC(Diagnostic Link Connector，诊断链路连接器)对OBD***进行访问，这个DLC即OBD接口。OBD接口共有16个引脚，16个引脚中的引脚用于连接OBD***中的总线，每个总线都有对应的协议以实现通信。车辆启动检测装置可以通过OBD接口按照协议标准访问OBD***，与OBD***实现通信，获取所需的信息。在本申请实施例中，与OBD接口相连接的外部设备可以理解为OBD设备。Before describing the vehicle startup detection method according to the embodiment of the present invention, the OBD system of the vehicle is briefly described first. The OBD system is the On-Board Diagnostics system, which means on-board automatic diagnosis system, which refers to the detection of the main engine of the vehicle based on the computer system. component performance. The OBD system can be accessed through the DLC (Diagnostic Link Connector), which is the OBD interface. The OBD interface has a total of 16 pins, and the pins in the 16 pins are used to connect the buses in the OBD system, and each bus has a corresponding protocol to realize communication. The vehicle startup detection device can access the OBD system according to the protocol standard through the OBD interface, communicate with the OBD system, and obtain the required information. In this embodiment of the present application, an external device connected to an OBD interface may be understood as an OBD device.

图1示出了本发明实施例提供的车辆启动检测方法的流程图，该方法由车辆启动检测装置执行。该车辆启动检测装置可以是OBD设备中的一部分，车辆启动检测装置中具有用于与OBD***通讯的通讯模块以及与OBD***电源接口连接的电源信息采集模块。如图1所示，该方法包括以下步骤：FIG. 1 shows a flowchart of a vehicle startup detection method provided by an embodiment of the present invention, where the method is executed by a vehicle startup detection device. The vehicle startup detection device can be a part of the OBD equipment, and the vehicle startup detection device has a communication module for communicating with the OBD system and a power supply information acquisition module connected to the power interface of the OBD system. As shown in Figure 1, the method includes the following steps:

步骤101：监测目标车辆是否振动。Step 101: Monitor whether the target vehicle vibrates.

在本发明的一个实施例中，车辆启动检测装置中设置有预设类型的传感器，通过该传感器实时或者周期性地获取目标车辆的振动传感数据，根据振动传感数据确定目标车辆是否存在振动。具体的传感器类型可以是加速度传感器。In an embodiment of the present invention, a preset type of sensor is set in the vehicle startup detection device, the vibration sensing data of the target vehicle is acquired in real time or periodically through the sensor, and whether the target vehicle vibrates is determined according to the vibration sensing data . The specific sensor type may be an acceleration sensor.

现有技术中在检测车辆启动时，先检测OBD电压，将OBD电压作为车辆检测的触发条件，但新能源以及混合动力车由于没有发电机，不适用于车辆启动后，发动机带动发电机，通过发电机对车辆电池组进行充电，因此根据采集到的OBD电压和发电机转数相关的检测原理，其OBD电压应该是一个恒定值或者在车辆启动时波动小到可以忽略，因此现有技术的触发方式不适用于新能源或者混合动力车型的检测。In the prior art, when the vehicle is started, the OBD voltage is detected first, and the OBD voltage is used as the trigger condition for vehicle detection. However, since new energy and hybrid vehicles do not have a generator, it is not suitable for the engine to drive the generator after the vehicle is started. The generator charges the battery pack of the vehicle. Therefore, according to the detection principle related to the collected OBD voltage and the number of revolutions of the generator, the OBD voltage should be a constant value or the fluctuation should be negligible when the vehicle starts. The trigger method is not applicable to the detection of new energy or hybrid vehicles.

而各种类型的车辆在启动时都会由于动力单元(如发动机)的启动而存在一定程度的振动，因此本发明将检测到振动作为车辆启动检测的触发条件可以适用于各种车型。However, various types of vehicles will have a certain degree of vibration due to the starting of the power unit (such as the engine) when starting, so the present invention uses the detected vibration as the triggering condition for vehicle starting detection, which can be applied to various vehicle types.

本发明采用振动触发启动检测过程，只有在监测到目标车辆存在振动的情况下，才判定该振动可能是由于车辆启动所引起的，从而继续进行后续的检测步骤。这样既适用于各种车型的检测，又不用保持车辆启动检测装置的各个模块的持续唤醒以及循环扫描OBD***的总线通讯数据，从而在不耗费车辆电能的同时也不会因为总线通讯频繁而影响车辆的性能。The present invention adopts the vibration-triggered start-up detection process, and only when the vibration of the target vehicle is detected, it is determined that the vibration may be caused by the start of the vehicle, and the subsequent detection steps are continued. This is not only suitable for the detection of various types of vehicles, but also does not need to keep the various modules of the vehicle startup detection device continuously wake up and cyclically scan the bus communication data of the OBD system, so that it does not consume vehicle power and will not be affected by frequent bus communication. vehicle performance.

在本发明的一个实施例中，步骤101中根据振动传感数据确定是否存在振动的过程包括：In an embodiment of the present invention, the process of determining whether there is vibration according to the vibration sensing data in step 101 includes:

步骤1011，获取所述目标车辆的振动传感信息。振动传感数据可以是目标车辆的振动波形数据，其获取可以是实时获取，也可以是周期性获取。在可选的实施例中，还可以对获取到的振动传感信息进行滤波处理，从而排除环境噪声干扰，提高车辆启动检测的准确率。Step 1011, acquiring vibration sensing information of the target vehicle. The vibration sensing data may be the vibration waveform data of the target vehicle, which may be acquired in real time or periodically. In an optional embodiment, the acquired vibration sensing information may also be filtered, so as to eliminate environmental noise interference and improve the accuracy of vehicle startup detection.

根据所述振动传感信息确定所述目标车辆在第三预设时长内的振动特征值。在本发明的一个实施例中，振动特征值包括振动幅度特征值，第三预设时长可以与后续第一预设时长相同，也可以不同。将振动特征值与预设的振动特征值阈值进行比较，包括将振动幅度特征值与振动幅度特征值阈值进行比较。The vibration characteristic value of the target vehicle within a third preset time period is determined according to the vibration sensing information. In an embodiment of the present invention, the vibration characteristic value includes a vibration amplitude characteristic value, and the third preset duration may be the same as or different from the subsequent first preset duration. Comparing the vibration characteristic value with a preset vibration characteristic value threshold includes comparing the vibration amplitude characteristic value with the vibration amplitude characteristic value threshold.

可以根据各个车辆的车型状况来设定振动幅度特征值阈值作为振动特征值阈值，这是因为考虑到不同车型的振动时的平均特征情况可能存在差异，如较大型的车辆在启动时的振动幅度可能较大，而一些特殊设计的车型的启动时的振动幅度较小。The vibration amplitude characteristic value threshold can be set as the vibration characteristic value threshold value according to the vehicle type of each vehicle. This is because there may be differences in the average characteristic situation when considering the vibration of different vehicle types, such as the vibration amplitude of a larger vehicle when it is started. May be larger, and some specially designed models have smaller vibration amplitudes at startup.

在所述振动特征值大于所述振动特征值阈值时，确定所述目标车辆存在振动。具体的，可以是振动幅度特征值大于振动幅度特征值阈值时，确定所述目标车辆存在振动。When the vibration characteristic value is greater than the vibration characteristic value threshold, it is determined that there is vibration in the target vehicle. Specifically, it may be determined that the target vehicle vibrates when the characteristic value of the vibration amplitude is greater than the threshold value of the characteristic value of the vibration amplitude.

步骤102：当监测到所述目标车辆振动时，获取所述目标车辆的OBD电压。Step 102: When the vibration of the target vehicle is monitored, obtain the OBD voltage of the target vehicle.

OBD电压是指的是OBD接口中的常电接口上输出的目标车辆的蓄电池电压。在目标车辆在点火启动之后，发动机开始转动并为蓄电池充电，因此在车辆从未启动到启动的状态，常电接口上检测到的OBD电压会存在较大的波动，可以作为车辆启动的检测条件。考虑到在实际应用中，目标车辆所存在的振动可能由多种原因造成的，如车辆的启动、外物撞击或者车载物体的移动等，因此，在检测到目标车辆振动的情况下，还需要进一步结合其他随着车辆启动会产生明显变化的参数，如OBD电压来进行车辆启动的检测。The OBD voltage refers to the battery voltage of the target vehicle that is output on the normal power interface in the OBD interface. After the target vehicle is ignited and started, the engine starts to rotate and charges the battery. Therefore, when the vehicle is not started to start, the OBD voltage detected on the normal power interface will fluctuate greatly, which can be used as a detection condition for vehicle start-up. . Considering that in practical applications, the vibration of the target vehicle may be caused by various reasons, such as the start of the vehicle, the impact of foreign objects or the movement of the vehicle, etc. Therefore, when the vibration of the target vehicle is detected, it is also necessary to The vehicle startup detection is further combined with other parameters, such as OBD voltage, that will change significantly when the vehicle is started.

步骤103：确定所述OBD电压是否存在波动。Step 103: Determine whether the OBD voltage fluctuates.

OBD电压波动指的是OBD电压在短时间内出现较大变化。在车辆未启动时，发动机未转动，无法带动车辆的发电机充电，因此OBD***未通电启动，因此OBD的常电接口(即第16脚)没有信号输出。而车辆点火之后，OBD的16脚的常电接口会产生输出信号的跳跃式增长，即OBD电压跃升到预设值。从而可以根据OBD电压的波动情况来判断车辆是否启动。OBD voltage fluctuation refers to a large change in OBD voltage in a short period of time. When the vehicle is not started, the engine is not running, and the vehicle's generator cannot be driven to charge, so the OBD system is not powered on to start, so the OBD's normally powered interface (ie, pin 16) has no signal output. After the vehicle is ignited, the 16-pin constant power interface of the OBD will produce a jumping increase in the output signal, that is, the OBD voltage will jump to the preset value. Therefore, it can be judged whether the vehicle is started according to the fluctuation of the OBD voltage.

在本发明的一个实施例中，可以通过电压特征值与特征值阈值进行比较来确定OBD电压是否存在波动。因此，步骤103包括：In one embodiment of the present invention, whether there is a fluctuation in the OBD voltage may be determined by comparing the voltage characteristic value with the characteristic value threshold. Therefore, step 103 includes:

步骤1031：获取第二预设时长内所述OBD电压对应的当前电压特征值。Step 1031: Acquire the current voltage characteristic value corresponding to the OBD voltage within the second preset time period.

第二预设时长可以是从监测到振动后的一段时长，可以和步骤1012中的第一预设时长相同。获取目标车辆在第二预设时长内的OBD电压，根据第二预设时长内的OBD电压确定第二预设时长内的电压平均值、电压平均频率以及电压极值作为所述当前电压特征值，其中，电压极值包括电压最大值和电压最小值。The second preset period of time may be a period of time after the vibration is monitored, and may be the same as the first preset period of time in step 1012 . Obtain the OBD voltage of the target vehicle within the second preset time period, and determine the voltage average value, the voltage average frequency and the voltage extreme value within the second preset time period according to the OBD voltage within the second preset time period as the current voltage characteristic value , where the voltage extreme includes the maximum voltage and the minimum voltage.

步骤1032：将所述当前电压特征值与预设的特征值阈值进行比较，其中，所述特征值阈值是根据所述目标车辆的历史OBD电压的电压特征值确定的电压特征值变化率。Step 1032 : Compare the current voltage characteristic value with a preset characteristic value threshold, wherein the characteristic value threshold is a voltage characteristic value change rate determined according to the voltage characteristic value of the historical OBD voltage of the target vehicle.

获取目标车辆在预设历史时长内的历史OBD电压数据，根据历史OBD电压数据确定目标车辆的历史OBD电压的特征值作为特征值阈值，其中，特征值阈值包括电压频率阈值、电压平均值阈值以及电压极值阈值。Acquire historical OBD voltage data of the target vehicle within a preset historical period, and determine, according to the historical OBD voltage data, a characteristic value of the historical OBD voltage of the target vehicle as a characteristic value threshold, wherein the characteristic value threshold includes a voltage frequency threshold, a voltage average threshold and Voltage extreme threshold.

将所述当前电压特征值与预设的特征值阈值进行比较可以包括：将电压平均值、电压平均频率以及电压极值分别与电压频率阈值、电压平均值阈值以及电压极值阈值进行比较。Comparing the current voltage characteristic value with a preset characteristic value threshold may include: comparing the voltage average value, the voltage average frequency and the voltage extreme value with the voltage frequency threshold value, the voltage average value threshold value and the voltage extreme value threshold value, respectively.

步骤1033：在所述当前电压特征值大于所述特征值阈值时，确定所述OBD电压存在波动。Step 1033: When the current voltage characteristic value is greater than the characteristic value threshold, determine that the OBD voltage fluctuates.

所述当前电压特征值大于所述特征值阈值的情况可以包括电压平均值大于电压平均值阈值、电压平均频率大于电压频率阈值以及电压极值大于电压极值阈值中的至少一种。The condition that the current voltage characteristic value is greater than the characteristic value threshold value may include at least one of the voltage average value being greater than the voltage average value threshold value, the voltage average frequency being greater than the voltage frequency threshold value and the voltage extreme value being greater than the voltage extreme value threshold value.

在本发明的再一个实施例中，可以通过电压特征值变化率与预设的变化率阈值进行比较来确定OBD电压是否存在波动。步骤103还包括：In yet another embodiment of the present invention, whether there is fluctuation in the OBD voltage may be determined by comparing the change rate of the voltage characteristic value with a preset change rate threshold. Step 103 also includes:

步骤1034：获取第二预设时长内所述OBD电压对应的当前电压特征值。Step 1034: Acquire the current voltage characteristic value corresponding to the OBD voltage within the second preset time period.

步骤1034与步骤1031相同，不再赘述。Step 1034 is the same as step 1031 and will not be repeated.

步骤1035：根据所述当前电压特征值确定所述目标车辆在所述第二预设时长内的当前电压特征值变化率。Step 1035: Determine the current voltage characteristic value change rate of the target vehicle within the second preset time period according to the current voltage characteristic value.

当前电压特征值变化率可以是目标车辆在第二预设时长内的OBD电压的电压平均值变化率、电压频率变化率。The current voltage characteristic value change rate may be the voltage average change rate and the voltage frequency change rate of the OBD voltage of the target vehicle within the second preset time period.

步骤1036：将所述当前电压特征值变化率与预设的变化率阈值进行比较，其中，所述变化率阈值是根据所述目标车辆的历史OBD电压的电压特征值变化率确定的。Step 1036 : Compare the change rate of the current voltage characteristic value with a preset change rate threshold, wherein the change rate threshold is determined according to the change rate of the voltage characteristic value of the historical OBD voltage of the target vehicle.

变化率阈值包括电压平均值变化率阈值、电压频率变化率阈值以及电压极值变化率阈值。The rate-of-change thresholds include a threshold for the rate of change of the voltage average value, the threshold for the rate of change of the voltage frequency, and the threshold for the rate of change of the voltage extreme value.

将所述当前电压特征值变化率与预设的变化率阈值进行比较可以分别是将电压平均值变化率、电压频率变化率以及电压极值变化率与电压平均值变化率阈值、电压频率变化率阈值以及电压极值变化率阈值进行比较。Comparing the rate of change of the current voltage characteristic value with the preset rate of change threshold may be the rate of change of the voltage average value, the rate of change of the voltage frequency, the rate of change of the extreme voltage value and the threshold value of the rate of change of the voltage average value, the rate of change of the voltage frequency, and the rate of change of the voltage average value. The threshold value and the voltage extreme value change rate threshold value are compared.

步骤1037：在所述当前电压特征值变化率大于所述变化率阈值时，确定所述OBD电压存在波动。Step 1037: When the rate of change of the current voltage characteristic value is greater than the threshold of the rate of change, determine that the OBD voltage fluctuates.

在所述电压特征值大于所述特征值阈值时并且电压特征值变化率大于所述变化率阈值时，确定所述OBD电压存在波动。When the voltage characteristic value is greater than the characteristic value threshold value and the voltage characteristic value change rate is greater than the change rate threshold value, it is determined that there is a fluctuation in the OBD voltage.

这样结合电压特征值变化率以及电压特征值进行判断的有益效果在于：不同车型的由于电池组参数存在差异，其在车辆启动后电池电压值不同，如果用固定的电压值阈值进行所有车型的电池电压的比较，会导致车辆启动判断不准确。与此同时，不同的车辆电池电压在启动后的波动范围也存在差异，故采取固定的波动值阈值来进行电压波动检测也无法适应全部车型情况。The beneficial effect of judging by combining the rate of change of the voltage characteristic value and the voltage characteristic value in this way is that due to the differences in the battery pack parameters of different models, the battery voltage values are different after the vehicle is started. The comparison of voltage will lead to inaccurate judgment of vehicle startup. At the same time, there are differences in the fluctuation range of the battery voltage of different vehicles after starting, so the use of a fixed fluctuation value threshold for voltage fluctuation detection cannot be adapted to all vehicle models.

因此根据电压特征值变化率和电压特征值综合进行判断，确定目标车辆的OBD，这样就避免了不同车型的电池参数的变化所导致单一根据固定OBD电压阈值的比较来进行启动判断的不准确的问题。Therefore, the OBD of the target vehicle is determined according to the comprehensive judgment of the change rate of the voltage characteristic value and the voltage characteristic value, which avoids the inaccuracy of starting judgment based on the comparison of the fixed OBD voltage thresholds caused by the change of the battery parameters of different models. question.

步骤104：若确定所述OBD电压存在波动，获取所述目标车辆的OBD通讯数据。Step 104: If it is determined that the OBD voltage fluctuates, obtain the OBD communication data of the target vehicle.

只有在OBD电压也存在波动时才进行OBD通讯数据的获取，以此来克服现有技术中实时对OBD通讯数据进行扫描获取所存在的以下缺陷：因为完成一次OBD接口扫描的时间较长，如果短时间循环扫描则耗电较多，如果扫描间隔长则会导致车辆启动识别延迟较长。并且车辆在OFF状态下时，车辆的各***的ECM处于待机状态，此时如果总线频繁有数据通信可能导致ECM异常激活，从而导致车辆异常。The acquisition of OBD communication data is only carried out when the OBD voltage also fluctuates, so as to overcome the following defects in real-time scanning and acquisition of OBD communication data in the prior art: because it takes a long time to complete an OBD interface scan, if A short-time cycle scan will consume more power, and if the scan interval is long, it will cause a long delay in vehicle startup recognition. In addition, when the vehicle is in the OFF state, the ECM of each system of the vehicle is in a standby state. At this time, if there is frequent data communication on the bus, the ECM may be abnormally activated, thereby causing the vehicle to be abnormal.

容易理解的是，由于新能源或者混合动力等车型的OBD电压在车辆启动时并不波动，因此在目标车辆的OBD电压不波动时，可能存在的原因有如下：车辆未启动、车辆启动但是目标车辆的车型为新能源车或混合动力车。而在车辆启动但是车型为新能源车或混合动力车的情况下，车辆的振动会随着启动而持续一段时间，而在车辆未启动时所检测到的振动是由其他外界偶发原因引起，因此振动不会持续，因此在OBD电压可以用振动是否连续来进一步筛除掉车辆未启动的情况。It is easy to understand that since the OBD voltage of new energy or hybrid vehicles does not fluctuate when the vehicle is started, when the OBD voltage of the target vehicle does not fluctuate, the possible reasons are as follows: the vehicle does not start, the vehicle starts but the target The model of the vehicle is a new energy vehicle or a hybrid vehicle. However, when the vehicle is started but the model is a new energy vehicle or a hybrid vehicle, the vibration of the vehicle will continue for a period of time with the start, and the vibration detected when the vehicle is not started is caused by other external accidental reasons, so The vibration does not last, so the OBD voltage can be used to further screen out the situation of the vehicle not starting by whether the vibration is continuous.

为了进一步提高车辆启动检测的准确率，还可以进一步获取OBD通讯数据，根据OBD通讯数据来进行车辆启动的检测。In order to further improve the accuracy of vehicle startup detection, OBD communication data may be further obtained, and vehicle startup detection may be performed according to the OBD communication data.

步骤105：根据所述OBD通讯数据确定所述目标车辆是否启动。Step 105: Determine whether the target vehicle is started according to the OBD communication data.

首先，在车辆未启动的情况下，OBD***未启动，总线上不存在OBD通讯数据，因此OBD通讯数据为空，更进一步的，首先是静默接收总线上的OBD通讯数据，判断总线上是否存在OBD通讯数据。First of all, when the vehicle is not started, the OBD system is not started, and there is no OBD communication data on the bus, so the OBD communication data is empty. Further, the first is to silently receive the OBD communication data on the bus, and determine whether the bus exists. OBD communication data.

在未接到总线上的OBD通讯数据时，在目标车辆包含发动机的实施例中，还可以发送发动机转速获取请求给OBD***，获取OBD***返回的数据，在未启动的情况下，OBD***是没有返回数据的，因此也可以在没有接受到返回数据时判断出车辆未启动。即在没有读取到发动机转速或者读取到的发动机转速小于预设值时，确定车辆未启动。When the OBD communication data on the bus is not received, in the embodiment where the target vehicle includes an engine, an engine speed acquisition request can also be sent to the OBD system to obtain the data returned by the OBD system. There is no return data, so it can also be judged that the vehicle is not started when no return data is received. That is, when the engine speed is not read or the read engine speed is less than the preset value, it is determined that the vehicle is not started.

在本发明的一个实施例中，步骤105包括：In one embodiment of the present invention, step 105 includes:

步骤1051：确定所述OBD通讯数据是否为空。Step 1051: Determine whether the OBD communication data is empty.

步骤1052：当所述OBD通讯数据不为空时，确定所述目标车辆启动。Step 1052: When the OBD communication data is not empty, determine that the target vehicle is started.

在本发明的再一个实施例中，若所述目标车辆包括发动机，步骤105还包括：In yet another embodiment of the present invention, if the target vehicle includes an engine, step 105 further includes:

步骤1053：当所述OBD通讯数据不为空时，根据所述OBD数据确定所述目标车辆的发动机转速。Step 1053: When the OBD communication data is not empty, determine the engine speed of the target vehicle according to the OBD data.

发送发动机转速获取请求给OBD***，获取OBD***返回的OBD通讯数据，根据OBD通讯数据确定目标车辆的发动机转速。Send the engine speed acquisition request to the OBD system, obtain the OBD communication data returned by the OBD system, and determine the engine speed of the target vehicle according to the OBD communication data.

步骤1054：将所述发动机转速与预设转速值进行比较。Step 1054: Compare the engine speed with a preset speed value.

步骤1055：当所述发动机转速大于所述预设转速值时，确定所述目标车辆启动。Step 1055: When the engine speed is greater than the preset speed value, determine that the target vehicle is started.

预设转速值可以为0，意即只要发动机存在转速，则表示车辆已经启动。The preset speed value can be 0, which means that as long as the engine has a speed, it means that the vehicle has been started.

在确定车辆启动之后，即可以通过OBD接口获取车辆运行过程中各种参数，根据参数进行车辆状态的实时诊断，可以至少包括：After it is determined that the vehicle is started, various parameters during the operation of the vehicle can be obtained through the OBD interface, and the real-time diagnosis of the vehicle status can be performed according to the parameters, which can at least include:

步骤1061：根据所述OBD通讯数据确定所述目标车辆的运行状态信息。Step 1061: Determine the running state information of the target vehicle according to the OBD communication data.

提取出OBD通讯数据中包括的参数数据，具体包括但不限于目标车辆的发送机转速、车速信息、油耗信息、排放信息以及位置信息中的至少一项。The parameter data included in the OBD communication data is extracted, specifically including but not limited to at least one of the target vehicle's transmitter speed, vehicle speed information, fuel consumption information, emission information, and location information.

步骤1062：根据所述运行状态信息确定所述目标车辆是否存在异常。Step 1062: Determine whether the target vehicle is abnormal according to the operating state information.

将各项运行状态信息与对应的预设的阈值进行比较，根据比较结果确定目标车辆是否存在异常。Comparing each item of operating state information with a corresponding preset threshold, and determining whether the target vehicle is abnormal according to the comparison result.

如在目标车辆的排放量大于预设的排放量阈值时，确定排放超标，因此目标车辆存在异常。For example, when the emission of the target vehicle is greater than the preset emission threshold, it is determined that the emission exceeds the standard, so the target vehicle is abnormal.

步骤1063：在确定所述目标车辆存在异常时，进行报警提醒。Step 1063: When it is determined that the target vehicle is abnormal, alarm and remind.

有益效果在于，在检测到目标车辆启动之后，与OBD***继续进行通讯，根据通讯数据对目标车辆的运行状态进行检测，监控目标车辆的尾气排放状态。The beneficial effect is that after detecting the start of the target vehicle, the communication with the OBD system is continued, the running state of the target vehicle is detected according to the communication data, and the exhaust emission state of the target vehicle is monitored.

通过上述方式，可以在检测到车辆启动后再监控目标车辆的运行状态，降低目标车辆未运行时的功耗，使监控场景更加智能。Through the above method, the running state of the target vehicle can be monitored after the vehicle startup is detected, the power consumption when the target vehicle is not running can be reduced, and the monitoring scene can be made more intelligent.

因此，在本发明的再一个实施例中，针对车辆启动进行检测的过程还可以如图2所示。Therefore, in yet another embodiment of the present invention, the process of detecting vehicle startup may also be as shown in FIG. 2 .

参考图2，图2中的步骤201与前述步骤101相同，步骤202与前述步骤102相同，不再赘述。Referring to FIG. 2 , step 201 in FIG. 2 is the same as the aforementioned step 101 , and step 202 is the same as the aforementioned step 102 , and will not be repeated here.

在步骤203之后，执行步骤204：当所述OBD电压不存在波动时，确定所述目标车辆的振动是否连续。After step 203, step 204 is executed: when there is no fluctuation in the OBD voltage, it is determined whether the vibration of the target vehicle is continuous.

在本发明的一个实施例中，确定目标车辆的振动是否连续，可以通过振动时长来确定，具体包括：In an embodiment of the present invention, determining whether the vibration of the target vehicle is continuous may be determined by the vibration duration, which specifically includes:

步骤2041：获取所述目标车辆的振动传感信息。Step 2041: Acquire vibration sensing information of the target vehicle.

还可以对振动传感信息进行滤波处理。The vibration sensing information can also be filtered.

步骤2042：根据所述振动传感信息确定所述目标车辆的振动时长。Step 2042: Determine the vibration duration of the target vehicle according to the vibration sensing information.

步骤2043：将所述振动时长与预设的时长阈值进行比较。Step 2043: Compare the vibration duration with a preset duration threshold.

步骤2044：在所述振动时长大于所述时长阈值时，确定所述目标车辆的振动连续。Step 2044: When the vibration duration is greater than the duration threshold, determine that the vibration of the target vehicle is continuous.

在本发明的再一个实施例中，可以通过结合振动时长及振动频率来判断振动是否连续，具体包括以下步骤：In yet another embodiment of the present invention, whether the vibration is continuous can be judged by combining the vibration duration and the vibration frequency, which specifically includes the following steps:

步骤2045：根据所述振动传感信息确定所述目标车辆在所述振动时长内的振动频率。Step 2045: Determine the vibration frequency of the target vehicle within the vibration duration according to the vibration sensing information.

步骤2046：将所述振动频率与预设的频率阈值进行比较。Step 2046: Compare the vibration frequency with a preset frequency threshold.

步骤2047：在所述振动频率大于所述频率阈值时，确定所述目标车辆的振动连续。Step 2047: When the vibration frequency is greater than the frequency threshold, determine that the vibration of the target vehicle is continuous.

在本发明的再一个实施例中，还可以采取结合目标车辆的振动时长以及在振动时长内的振动频率两者，综合进行目标车辆的振动是否连续的判断。即在目标车辆的振动时长大于所述时长阈值并且振动频率大于所述频率阈值时，确定目标车辆的振动连续。In yet another embodiment of the present invention, it is also possible to comprehensively judge whether the vibration of the target vehicle is continuous by combining both the vibration duration of the target vehicle and the vibration frequency within the vibration duration. That is, when the vibration duration of the target vehicle is greater than the duration threshold and the vibration frequency is greater than the frequency threshold, it is determined that the vibration of the target vehicle is continuous.

具体包括如下过程：Specifically, it includes the following processes:

获取所述目标车辆的振动传感信息。Acquire vibration sensing information of the target vehicle.

根据振动传感信息确定所述目标车辆的振动时长和振动频率。The vibration duration and vibration frequency of the target vehicle are determined according to the vibration sensing information.

将所述振动时长与预设的时长阈值进行比较，将所述振动频率与预设的频率阈值进行比较。The vibration duration is compared with a preset duration threshold, and the vibration frequency is compared with a preset frequency threshold.

在所述振动时长大于所述时长阈值并且所述振动频率大于所述频率阈值时，确定所述目标车辆的振动连续。When the vibration duration is greater than the duration threshold and the vibration frequency is greater than the frequency threshold, it is determined that the vibration of the target vehicle is continuous.

这样根据振动时长以及预设时长内的振动频率结合确定，可以确定检测到的振动是由于外力等因素引起的偶发且短暂的，还是与车辆启动时发动机的振动所造成的持续规律性振动不同。In this way, according to the combination of the vibration duration and the vibration frequency within the preset duration, it can be determined whether the detected vibration is occasional and short-lived due to factors such as external force, or is different from the continuous regular vibration caused by the vibration of the engine when the vehicle is started.

在步骤204之后，执行步骤205：若确定所述振动连续，获取所述目标车辆的OBD通讯数据。After step 204, step 205 is executed: if it is determined that the vibration is continuous, obtain the OBD communication data of the target vehicle.

在步骤205之后，执行步骤206，步骤206与前述步骤105相同，不再赘述。After step 205, step 206 is executed, and step 206 is the same as the aforementioned step 105, and will not be repeated.
