Tesla Inc (TSLA)

[boston745]

Interesting theres been little geomagnetic activity lately and no news of Teslas going out of control. Interesting how these two things correlate. Its almost as if geomagnetic activity, particularly on the surface of the earth, causes Tesla and other EVs to go out of control...

Tesla's EM radiation problem

This problem explains why when there is more solar & geomagnetic activity, there are more out of control Tesla events. When the sun & earths magnetic activity are low, all things seem quiet from the out of control accident front. While Teslas go out of control when the geomagnetic field has been disturbed, takes days for storms energy to subside, they do not always seem to make the news everytime theres geomagnetic activity. This is because a Tesla has to be in the wrong place at the wrong time where the soils conductivity allows for a build up of EM fields that can then induce these incidents. More EVs out there on the roads, the higher the probability that this becomes more 1:1 ratio. Meaning for every geomagnetic disturbance, a number of EVs will go out of control in such a way that it could make the news. However more often the EM interference causes minor computer glitching that people on the Tesla Motor Club complain about. Understand that im not even factoring in cosmic rays which occur all the time, because there is no way to connect the data to cosmic rays.

How Teslas data recorder fails to record the commands by their drivers giving investigators the wrong impression

New information received by the NHTSA shows that sudden unintended acceleration events with Tesla EVs were real and not driver errors. The report explains in detail what caused the cars to accelerate even when the accelerator pedal was not pressed.

What's worse is that the incorrectly increased sensor signals will be sent via the CAN bus to the vehicle logs, causing Tesla and NHTSA to conclude that the driver caused the sudden increase in torque by stepping on the accelerator pedal. But in this case, the sudden acceleration was caused not by the driver stepping on the accelerator pedal but by a random superposition of a negative-going voltage spike (which is about 100 microseconds long), and the sampling time of the analog-to-digital converter (which is about 10 microseconds long). This random superposition explains the low occurrence rate of sudden acceleration in Tesla vehicles

As posted previously this new petition will likely be dismissed as I don't think Teslas SUA problem is easily fixed as Dr. Belt suggests. Furthermore, Tesla is aware of its SUA problem, trying to fix it, and hasnt managed to yet.

What can cause the random negative voltage spikes is from induced currents from Electromagnetic Interference. E3 wave (which is similar to conditions during a geostorm) causes voltage depression in power lines and it seems in Tesla system as well. Like regulators at a substation, Tesla system seems to try to make up for this voltage depression causing voltage spikes leading to SUA and logs recording high accelerator pressure even though the driver hasn't touched the accelerator. This is explained a bit better in the following scientific study.


Proof Electromagnetic radiation is causing EVs to go out of control and spontaneously combust.

4). Among the data records during the accidents according to the background data of the crashed vehicles or the data of on-vehicle terminals, the position values of most accelerator pedals were very high(99%) while the values of brake pedals were 0% or only non-zero in very limited moments (see Fig. 1 and Fig. 2).

Continued very high accelerator pressure with no braking is how you differentiate SUA from pedal misapplication.

In  recent  years,  there  have  been  numerous  out-of-control  accidents  of  electric  vehicles.

Occasional fault of electronic control unit caused by  electromagnetic interference

External  electromagnetic  interference  refers  to  that  caused  by electromagnetic  radiation  of  various  electrical  facilities  including  the  high  voltage  transmission  line, broadcasting  TV  devices  and  radio  communication  equipment  as  well  as  natural  phenomena  such  as lightning.

Electromagnetic  wave  interferes  the  electric  control  system  of  automobile  through  wiring  harness and  car  body to  make  it  hard  to  perform  or  even  send  wrong  instructions leading  to  wrong  actions  of various  actuators,  affecting  the  safety,  reliability  and  stability  of  automobile  driving.  The electromagnetic  interference  affects  the  automobile  electronic  control  system  mainly  in  two  ways:  one is  to  affect  the  input  signal  of  the  sensor  of  the  electronic  control  system,  causing  distortion  and resulting  in  electric  control  signal  where  the  ECU  output  does  not  match  the  driver's  intention,  which leads  to  the  wrong  operation  of  the  actuator;  the  other  is  to  interfere  the  ECU  output  signal  to  result  in its deviation,  misleading the operation of  the actuator.
