I could see this coming years ago. DBW has its glitches... A test pilot crashed an Airbus plane because of similar glitches!
When I first got my (manual shift) Nitro, I was goofing around and revved the throttle ~3 times, each time pressing a little further, just to hear the new Magnaflow. On the ~3rd time the revs continued to climb (or at least stay high) AFTER my foot was off the throttle! It was climbing or holding @4000rpm all on its own... Luckily, I had the clutch out, but it was still unnerving. I somehow sensed what was happening (in my driveway) and simply turned the key off --B4 it started bouncing the needle off the limiter! And NO, a floormat wasn't involved. On restart, it was fine... :SHOCKED:
Gee, I can't wait for SBW Steer-By-Wire. ZERO mechanical linkage to the tires. Like that?! :thk:
And it is coming our way... So, as an Engineer, how would YOU design the failsafe or default for a spurious input signal?
