Wouldn’t it be cool if you could speak to your car and give it commands?
We remember our childhood in the last millennium where Michael Knight (David Hasselhoff) and his intelligent car Pontiac Trans Am named K.I.T.T. solved crime together.
Talking car is a dream of many car enthusiasts. Fortunately, due to AutoPi's features, you are able to obtain a talking car yourself easily.
It is possible to get audible alarms from your car and give it commands at the same time. Therefore, it can improve the driver experience, improve the efficiency and safety of the driver, as well as passengers.
Did you know? K.I.T.T. is short for Knight Industries Two Thousand
While we may not be able to have a meaningful conversation with our car just yet, it’s now a possibility to talk to your car and give it commands to execute.
We are here giving a short introduction to how this can be accomplished using the AutoPi.io system and Google Assistant.
With the Google Assistant, it will be like a K.I.T.T. voice software for your car, and thus the commands you give your vehicle once executed can feel like you are in Knight Rider.
Here's a demonstration of how you can talk to your car:
What is AutoPi?
AutoPi is a small device that plugs into the OBD-II
port of your car.
Once connected, the AutoPi device will automatically start working. It has 4G/LTE connectivity, so it is always connected to the Internet. It also comes with a lot of other features, one is continuous GPS tracking.
It comes with an advanced cloud management platform, that you can login to from any device. From here you can setup your system and do real-time tracking of your vehicle telematics.
What is Google Assistant?
Google Assistant is Google’s version of Siri (Apple) and Alexa (Amazon). It lets you interact with your device, through voice commands and has typically been used together with Android devices, where it comes integrated.
More technically, the “Assistants” works by processing the speech recorded on the device and translate them into something understandable by a machine and this can thereby be parsed and an action can be taken. A typical use case is:
- You: “OK Google. How is the weather in New York?”
- Assistant: “It’s 10 degrees and raining”
How to use Google Assistant and AutoPi together?
When Google introduced the Google Assistant SDK with a Python version, they must have thought of AutoPi, because the two things goes together perfectly.
- Speak a command using the USB microphone
- Send the recorded action to Google for parsing
- The device initiates the action, based on the result from Google
The flow between the systems is:
- User speaks a command.
- The K.I.T.T. Python application records and sends the spoken command to Google using the Assistant SDK.
- Google Cloud Platform translates the recorded speech into a text string.
- The text string is returned to the K.I.T.T. Python application, using the SDK.
- The K.I.T.T. Python application parses the text string and initiates the action found from the string, in this case the OBD subsystem.
- The OBD subsystem routine is triggered and it sends a command on the CAN bus through the OBD port. The command is to roll down the window.
- The window in the car is rolled down.
- The speaker subsystem routine is triggered. It sends the text to be spoken to Google to translate it into a sound file.
- Google returns the sound file.
- Speaker subsystem plays the sound file to the user.
- Great Success!
AutoPi was mentioned at the Google I/O 2017 conference in San Francisco. See the video below.

Many of our users prefer the DIY version of AutoPi and want to build their own ideas on top of that. Some of the most common ideas are building a Raspberry Pi touch screen carputer or car Wi-Fi hotspot.
You are more than welcome to do that and now you even have the chance to go get several steps ahead with our new developer kit, built exactly for this purpose. Get the developer kit here.
