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).
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.
The most common cause of Natural EMI includes:
Lightning
Solar Magnetic Storms
Earth’s Magnetic Field Flux
Cosmic Radiation
A driver lost control of a car in White Plains, veered onto a sidewalk and crashed into a tree and small apartment building, leaving two people inside the vehicle dead.
The incident occurred around 9:10 a.m. near 295 Battle Ave., according to Public Safety Commissioner David Chong.
The vehicle, believed to be a Tesla, exploded on impact, causing a fire in the building and significant damage.
When computers go wrong, we tend to assume it's just some software hiccup, a bit of bad programming. But ionising radiation, including rays of protons blasted towards us by the sun, can also be the cause. These incidents, called single-event upsets, are rare and it can be impossible to be sure that cosmic rays were involved in a specific malfunction because they leave no trace behind them.
And yet they have been singled out as the possible culprits behind numerous extraordinary cases of computer failure. From a vote-counting machine that added thousands of non-existent votes to a candidate's tally, to a commercial airliner that suddenly dropped hundreds of feet mid-flight, injuring dozens of passengers
Plus, since giant ejections from the sun can sometimes send huge waves of particles towards Earth, what's called space weather, an unnerving prospect looms: we could see much more disruption to computers than we're used to during a massive geomagnetic storm in the future
Tesla argues it had no control in the crash and death which were "caused by a superseding and/or intervening force."
I'm begging all of you to NEVER get in a Tesla as long as you live. It started accelerating on its own in a parking garage and my dad lost all control of the car and we ran into a wall at 40 mph. Most horrifying experience of my life.
Jain is one of tens of thousands of Tesla owners who have experienced premature failures of suspension or steering parts, according to a Reuters review of thousands of Tesla documents. The chronic failures, many in relatively new vehicles, date back at least seven years and stretch across Tesla’s model lineup and across the globe, from China to the United States to Europe, according to the records and interviews with more than 20 customers and nine former Tesla managers or service technicians.
