Sharing a bad experience with my 370Z

Jeffblue

interesting. an owner of a MT sports car has something flukey happen with drive by wire, he regains control of the car. the driver of a "safe family sedan" (toyota/lexus) has a similar throttle problem and .... they get killed.

glad your ok... and i'd be curious to know what they say caused this.

Brake pedal is supposed to kill the throttle, at least it does under normal circumstances. I guess the only way this could happen would be for the ECU to lose its mind. But obviously it was a case of temporary insanity if you were able to drive it to the dealer afterwards.

Sure your foot didn't slip off the brake onto the gas when you clipped the curb? I know they feel totally different but I've been known to fat foot it before where you are actually pressing the brake pedal and the accelerator at the same time.

the-truth

I am not certain I follow the logic of your question. If the ECU is supposed to override the throttle when or if the brake is depressed, how could pushing the brake pedal and accelerator at the same instant cause what happened to the origina poster? Would not this be the "lost mind" ECU scenario you were obviously being facetious about?

wheee!

Any chance it was the "magnetic" black paint colour??? Possible EMI issue here....

I seriously doubt fields from a power line are strong enough to do anything. They fall off as the square of the distance. In addition, there's more EMF from the ignition system of the car than anything else. The ECU is shielded from this. (H3ll, the car is basically a Faraday cage anyway - the insides are surrounded by the metal body.

In any case - a very close call. I'm glad you were not injured. The fact that this particular ECU was a bit flaky leads me to believe that the "re-set" did not completely solve the problem - maybe a hardware failure? I hope things get sorted quickly for you.

Doh - should have read the full thread - beat me to it!

I wouldn't be so quick to say that these issues are or aren't EMI related. Electric and magnetic fields are very complex. It usually isn't as easy as just saying that some particular unit is shielded by the body or some other means.

The car's body should do a good job shielding from electric fields but magnetic fields are a different issue. Thin sheet metal won't completely shield magnetic fields. Even though the ECU may be shielded the shielding doesn't prevent fields from being coupled onto wires entering or exiting the ECU.

Additionally, fields don't always fall off at at rate of 1/R^2. I work on some extremely high power equipment that was expected to produce fields that rolled off at a rate of 1/R^2 when in reality the measured results showed that the roll off was actually 1/R. The actual roll of of a field may be anywhere between 1/R to 1/R^4 depending on the source, location and the make up of the field.

With all that said I would tend to agree that it isn't likely that the problem is related to power lines but I would be looking closely at inter-compatibility issues with other electronics in the car. Either way it should be interesting to see how all of this plays out.

Sorry for being such an engineer.....

UPDATED! Link to damages. Rather than spam with 10 pictures.

Still waiting on reports from dealer, etc. I'll keep updated.

=( breaks my heart to see these pictures. but glad ur okay.

ouch glad to see ur ok

Sorry you had to experience this. Hopefully Nissan will stand up and do the right thing and not say it was "due to operator error". Good Luck!!

IDZRVIT

Nissan's fault? Hope the OP has insurance.

Hey, I posted in here and it was erased. Other people posted jokes. WTF?
