Tesla Inc (TSLA)

[boston745]

I should have said the lack of braking attempt coupled with max or near max accelerator pressure before crashing is example that there is something wrong inside the car. This is what the investigators noticed was common amongst the 5 cases that exhibited signs of electromagnetic interference. This is exactly what the Tesla taxi driver in Paris experienced with his Tesla as it sped off down the road injuring 20 people and killing 1.

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).
5). The drivers of the 5 accidents reported that the vehicle suddenly accelerated and the brake failed during the process of starting and could not be controlled. Besides, the drivers have long driving experience, and the bus drivers are all professional drivers.

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.
