Data science at advance auto parts
Devon Shackle and Lori? And two other folks on
Obd ii
Obd originated in the sixties
These codes are DTCS. They are accessible through a port on the drivers side under the dash.
Obd hacking first attempt
Car Porsche? If you can get one Obd cable to raspberry pi to Pyobd to jupyter to Notebook to data (to is - >)
Request all the commands the vehicle supports For c in connection.suppoerted_commands
Huge amounts of data in the car
Garrett from dragos. Director of telemetry
Raspberry pi to inter tubes to s3 buckets to elastic search to kibana
Showed real time hrv cam bus
Lambda function parses out the data and normalizes it. Then pumps it to elasticseaech
Then kibana gauges
Blake is in a Camaro outside. Data is federally mandated but it can vary wildly from one manufacturer to another
Q&a
How do you make sense of the data? Pyodb does a lot of the help in translating
Can you write back to the car? Clearing codes. It's a rabbit hole going back.
Whats the latency like? They used quarter second., can be lower if you want to do something specific. But quarter second is the lowest for getting all the data all the time
Is there any security? Just physical access
Is it possible to ddos the ecu? We don't know.
