While you’re still waiting on your refrigerator or your microwave to be as smart as your phone, the car in your garage is already ahead of the curve. If you own a vehicle made after 1996, you can connect to it with a simple device called an OBD-II adapter and find out your fuel efficiency, diagnose check engine lights, and gather a ton of other useful data.

当您还在等冰箱或微波炉等智能手机时，车库中的汽车已经超前了。如果您拥有1996年以后生产的汽车，则可以使用称为OBD-II适配器的简单设备连接该汽车，以查明燃油效率，诊断检查发动机灯并收集大量其他有用数据。

Most cars manufactured since the 80s have an on-board diagnostics (or OBD) computer inside. These computers allow mechanics and regulators to troubleshoot any computer-controlled parts of the car. From January 1st, 1996 onward, all cars sold within the US were required to have an OBD-II compatible port. This allows anyone with an adapter to read information from the car. You may have seen this when a technician checks your emissions.

自80年代以来制造的大多数汽车内部都装有车载诊断(或OBD)计算机。这些计算机使技工和调节员可以对汽车的任何计算机控制部件进行故障排除。从1996年1月1日起，所有在美国境内销售的汽车都必须具有与OBD-II兼容的端口。这样，任何拥有适配器的人都可以从汽车上读取信息。当技术人员检查您的排放物时，您可能已经看到了。

For the most part, OBD-II tools were only used by professionals to do things like figure out why you check engine light is on, or to make sure your car is meeting emission standards. However, OBD-II ports can be used to read a lot more helpful data. Recently, cheap Bluetooth adapters have made it possible for everyone to get access to that information.

在大多数情况下，OBD-II工具仅由专业人员用来做诸如弄清楚为什么检查引擎灯点亮或确保您的汽车符合排放标准之类的事情。但是，OBD-II端口可用于读取更多有用的数据。最近，便宜的蓝牙适配器使每个人都可以访问该信息。

您可以使用OBD-II适配器做什么 (What You Can Do With an OBD-II Adapter)

While this might all sound dry, everyday consumers can do a ton of cool stuff with even a cheap OBD-II adapter. You can buy a basic Bluetooth adapter for as little as $20, though there are more expensive ones that offer even more features. I own this one which is $22 on Amazon. With it, you can connect to apps like Dash (Android/iOS) and Torque (Android). It’s important to note that many of the cheaper Bluetooth adapters may drain the battery if they’re left plugged in. These should be okay as long as you drive your car every day (or if you’ll only plug it in when you want to diagnose a check engine light), but if you leave your car idle over the weekend, you may want a more high-end adapter.

虽然这可能所有的声音干，普通消费者可以做一吨的很酷的东西就算了，便宜的OBD-II适配器。您可以以低至20美元的价格购买基本的蓝牙适配器，尽管有更昂贵的适配器可以提供更多功能。我拥有这个，在亚马逊上是22美元。有了它，您可以连接到Dash( Android / iOS )和Torque( Android )等应用。重要的是要注意，许多便宜的蓝牙适配器如果插上电源，可能会耗尽电池。只要您每天开车(或者如果您只想在需要时才插上汽车)，这些适配器就可以了。诊断检查引擎灯)，但是如果您在周末闲置汽车，则可能需要更高端的适配器。

The more expensive whole-package OBD-II systems like Automatic ($80 for Lite, $130 for Pro, Android/iOS) come with adapters that connect to 3G networks, include GPS, and power-saving features, plus their own app. Depending on which adapter you get, you can do all kinds of things, including:

像Automatic这样较贵的整包OBD-II系统(Lite为80美元，Pro， Android / iOS为130美元)带有适配器，这些适配器可以连接3G网络，包括GPS和省电功能，以及自己的应用程序。根据获得的适配器，您可以执行各种操作，包括：

See how much your trips cost in gas. You probably know off the top of your head about how much it takes to fill up your tank. But how much does it take to drive to work? How much do you spend every time you drive across town to see a friend? Apps like Dash track how far you travel, compare that to the cost of gas in your area and how efficient your car is. For each trip, it can show you how much you spent to get there. It’s weirdly comforting to see that each trip to work costs $0.40.

看看您的旅行花费了多少汽油。 您可能完全不知道加满油箱需要多少费用。但是开车要花多少钱？每次开车穿过小镇去见朋友时，您花费多少？ Dash之类的应用程序可以跟踪您的行进距离，并将其与您所在地区的汽油成本以及您的汽车的效率进行比较。对于每次旅行，它都可以向您显示到达目的地的花费。奇怪的是，令人欣慰的是，每次上班旅行的成本为0.40美元。
Diagnose your check engine lights. The check engine light can mean any one of a hundred things are wrong, and you’ll never know until you go to your mechanic…unless you have an OBD-II adapter. Apps like Dash and Torque can give you a more specific error code. Sometimes the app can tell you exactly what that means, or you can Google it for more information. With this information, you can figure out whether you need to hurry to the mechanic right away, or if you just lost your gas cap.

诊断检查引擎指示灯。 检查引擎灯可能意味着一百个问题中的任何一个都不对，直到您去看机械师之前，您永远不会知道……除非您拥有OBD-II适配器。 Dash和Torque等应用可以为您提供更具体的错误代码。有时，该应用可以准确告诉您这是什么意思，或者您可以通过Google来获取更多信息。有了这些信息，您就可以确定是需要立即去找机械师，还是刚刚失去油门盖。
Remember where you parked your car. Basic adapters like the cheap ones listed above can connect to Dash and use your phone’s location to mark where you parked your car. When you leave, you can track it down from your phone. If you’re using Automatic Pro, it can locate your car even when it’s away from your phone. So, if a family member uses your car (or if it’s stolen), you can track exactly where it is from your phone.

记住您的车停在哪里。 上面列出的廉价适配器之类的基本适配器可以连接到Dash，并使用手机的位置标记您的停车位。离开时，您可以通过手机对其进行跟踪。如果您使用的是Automatic Pro，即使它不在手机旁，它也可以找到您的汽车。因此，如果家人使用您的汽车(或者被盗)，则可以通过手机准确地跟踪汽车的位置。
Get help from emergency services. This one alone may justify the cost of Automatic Pro. This adapter can detect when you’ve been in a severe car crash. An operator will then call your phone and ask if you need assistance. If you say yes (or if you don’t respond), they’ll call emergency services for you and send them to your location, which Automatic can also see. Their operators will also stay on the phone with you until emergency services arrive.

从紧急服务获得帮助。 仅此一项就可以证明Automatic Pro的成本是合理的。该适配器可以检测出您何时发生了严重的车祸。然后，接线员会打您的电话，询问您是否需要帮助。如果您说“是”(或者您没有回应)，他们将为您呼叫紧急服务并将其发送到您的位置，“自动”也可以看到。他们的接线员还将与您保持联系，直到紧急服务到达。
Connect to IFTTT, Alexa, and other smart apps. As if these tools weren’t powerful enough on their own, you can pair them with your host of other smart home gadgets through IFTTT. There are IFTTT channels for both Dash and Automatic that let you log check engine lights, turn your lights on when you get home (or turn them off when you leave), or send your partner a message when you leave for work. Automatic can also connect to Alexa so you can ask where your car is or whether you need to get gas.

连接到IFTTT，Alexa和其他智能应用程序。 好像这些工具本身不够强大，您可以通过IFTTT将它们与其他智能家居小工具配对。仪表板和自动仪表板都有IFTTT通道，可让您记录检查发动机灯，回家时打开灯(或离开时关闭灯)或在下班时向伴侣发送消息。自动也可以连接到Alexa，因此您可以询问您的汽车在哪里或是否需要加油。

That’s a lot of power for a basic diagnostic system from the mid 90s. If you want to add your car to your arsenal of smart home gadgets, you don’t need an expensive head unit or a brand new car. The cheaper Bluetooth adapters are an easy way to get started if you just want to dip your toes in, though Automatic offers a lot of benefits that you don’t get from generic OBD-II adapters.

从90年代中期开始，对于基本诊断系统而言，这具有很大的优势。如果要将汽车添加到智能家居小工具库中，则不需要昂贵的主机或全新汽车。便宜的蓝牙适配器是您入门的一种简便方法，尽管“自动”功能提供了许多普通OBD-II适配器无法获得的好处。

如何开始使用OBD-II适配器 (How to Get Started With Your OBD-II Adapter)

Once you’ve decided which type of adapter you want to use, you’ll need to plug it into your car. The OBD-II port on your car looks like this.

确定要使用哪种适配器后，需要将其插入汽车。您汽车上的OBD-II端口看起来像这样。

The port may be in different places depending on your model of car, but it’s legally required to be within two feet of the steering wheel. Usually, it’s just underneath the wheel, or near the fuse panel. Once you find it, plug the adapter in like so.

根据您的汽车型号，端口可能位于不同的位置，但是法律上要求端口在方向盘两英尺以内。通常，它就在车轮下方或保险丝面板附近。一旦找到它，就像这样插入适配器。

Next, open up your phone. Most adapters will use Bluetooth, so you’ll have to pair it to your phone. This process may be slightly different for each phone, but we’ve detailed the process for most devices here. Start by heading to your Bluetooth settings.

接下来，打开手机。大多数适配器将使用蓝牙，因此您必须将其与手机配对。每个电话的此过程可能略有不同，但是我们在此处详细介绍了大多数设备的过程。首先前往您的蓝牙设置。

Find the OBD-II adapter in the list of devices and tap on it.

在设备列表中找到OBD-II适配器，然后点击它。

You’ll then be asked to enter in the four-digit PIN for your adapter. You can find this in the instructions that came with your adapter, but as the prompt says, it’s usually 0000 or 1234. Once you’ve entered the PIN, tap OK.

然后，将要求您输入适配器的四位数PIN。您可以在适配器随附的说明中找到它，但是如提示所示，通常为0000或1234。输入PIN后，点击“确定”。

You should now see your adapter in your list of devices.

现在，您应该在设备列表中看到适配器。

You can now open up your various OBD-II apps we mentioned earlier connect to your car. We recommend Dash in particular for logging information about your car and tracking your trips. Automatic Pro will have a different set up process, since it uses 3G to track your car rather than Bluetooth, but Automatic Lite should work just like any other Bluetooth adapter.

现在，您可以打开我们前面提到的连接到汽车的各种OBD-II应用程序。我们特别推荐Dash ，用于记录有关您的汽车的信息并跟踪您的行程。由于Automatic Pro使用3G而不是蓝牙来跟踪您的汽车，因此Automatic Pro的设置过程会有所不同，但是Automatic Lite应与任何其他蓝牙适配器一样工作。
