Door een spanning verschil kan de auto anders reageren. Zie potentiële impact op de foto.
Twee van de beste onafhankelijke Tesla specialisten verklaren onafhankelijk van elkaar dat dit fysiek onmogelijk is door de manier waarop de systemen zijn ontworpen.
“Hughes doesn't believe a drop in the 12-volt rail voltage, as described in the petition, will cause a calibration error leading to an SUA event. The 12-volt rail is monitored by dozens of modules, which would log any low-voltage conditions. Hughes has personally analyzed logs resulting from SUA crashes and thinks a situation like the one described in Ronald Belt's petition is impossible. No log he examined suggests an associated 12-volt drop of any kind, and the NHHTSA had the same information when it decided to close the SUA investigation.
"Tesla's accelerator pedal power, while derived from the 12-volt system, is using two independent isolated 5-volt supplies," writes Hughes. "There is no way for a fault in that system to create the correct signals for full acceleration. It's not possible. If somehow the 12-volt system were so low it caused the isolated 5-volt supplies and their capacitors to drop below the expected voltages, that'd sag the entire curve of the dual sensors, leading to a pedal fault, not full acceleration."
Another known Tesla hacker, Green (@greentheonly), thinks that the claims in the paper should be easy to validate if anyone with a spare inverter controller PCB is willing to try. Still, this should be the first task on the NHTSA's experts' agenda. Hopefully, they will get to the bottom of this issue and clear the waters regarding Tesla's sudden unintended acceleration.”
In simpel Nederlands: een voltage drop kan nooit leiden tot acceleratie maar leidt tot een niet werkend pedaal.

Één van die experts is overigens Jason Hughes wiens website ik hier nu een keer of vier gedeeld heb met het advies om met hem contact op te nemen.
