We are looking to conduct research into automotive technology and were wondering if there exists some device/rig that can help in measuring vehicle parameters to establish ground truth. We would like to outfit a couple of vehicles with these sensors like that could give us accurate measures of distance, speed, fuel level, fuel consumption, etc.
Eg. wheel encoders could give us distance and speed.
Where can I get more information about this? How do the car manufacturers do this testing? Would we have to approach the manufacturers themselves to get the data?
Thank you for your help!
