Do not try this at home, you might hurt your car. This was done to test 7N0 radar's ability to prevent a low speed impact.
Testing was performed with a tractor pulling a sled (pallet) with cardboard boxes stuffed with balloons. The face of the boxes were wrapped in 2 layers of aluminum foil so the radar would detect them as if it were a moving vehicle.
Recording was done with SavvyCAN software and Tactrix OpenPort 2.0 as a passthru device connected to the powertrainCAN. While retrofitting the EPB I added an OBD2 port under the driver's seat for the recording ability.
