Car Diagnostics With A Raspberry PI - DIY Smart Car (Part 3)
Рет қаралды 307,680
6 жыл бұрынShhh...can you hear it? Your car is talking. It's saying "Make me smart, please". It also says things like "I'm going 50 km/hr" or "My wheels are spinning at 3200 RPM", classic stuff like that. In order to hear all the cool stuff your car has to say, you need to connect to it's OBDII port, which all US cars made after 1996 have. Then we can just connect it to a Raspberry Pi and add it to our ever growing smart car!

You know this is a very cool idea and information. :D It would be interesting to also use a LED grid to setup a HUD to reflect off of your windshield so you could see your KPH or MPH so you wouldn't have to look down at the dash. Another nifty thing would be to see if you could also add in a dash cam type system so you could record stuff as you are driving so you have proof of what happened in front of you if you got into a accident plus encode the MPH/KPH and other vehicle features into the overlay when it is being recorded so you could show if you were using your turn signals, hit your breaks, or other things that might be useful. :D I could think of so many nifty things you could do on this project. :D Maybe some current sensors on your head lights and other external lights so you know when they are working or need replacing. :D

Hi, fantastic video! Do you think its possible to be able to access dealer specific things like the air bag module, or abs module, steering module, etc, etc,and pull off and reset codes for these too or even calibrate or reprogram options? Basically anything that is programmerble from the manufacturer? Just curious. I guess alot of these require inside knowledge.

Torque on Android is an excellent off-the-shelf solution that will connect to bluetooth OBD2 readers. Add Torque's overlay to the camera feed from your last video and get a maybe get a cool dashcam. Of course, there are dashcam apps too. Or, wait... Hopefully I'm not spoiling your video for a few weeks away... OBD2 overlay on dashcam and backup cam recorded and displayed on the Raspberry Pi.

When I got my Chevy Volt in 2012, I put an OBD2 bluetooth adapter on it to see what data I could read from the car using some phone apps. It worked for a few days and then my car would not start. I removed the adapter and got it to start, but it had created several faults that had to be cleared at the dealership. Apparently the increase in traffic on the network interferes with the module communications. This happens on several other Chevy models also. Be careful. BTW, I also have a Honda Odyssey, which requires a special OBD adapter, so you can't just buy any adapter for it.

@adubs. 6 жыл бұрын
The calculation is usually done from injector duty cycle and MAF. AFAIK only a few manufacturers use the fuel level to aid in calculation. Even then there are a ton of discrepancies, like tire wear, changes in fuel density, injector flow tolerance, etc. My point was there is a way to monitor this information via OBDII. A cheap bluetooth setup as shown connected to an android running the torque app will show you. Though its probably still far more accurate to plot the data yourself at the pump.

From there I would have this same set control door locks and other features in the car. I would end up installing sensors everywhere to monitor things a little better. It would also remind me about maintenance..... God I could go on forever... I do believe this would need a more powerful computer along with endless serial input
