The ECU Just Needs Software Code Added to Ignore the SHORTED Pedal Conditions
Being a software programmer, I am shocked that a large company selling millions of products each year would not have this software code that only acts on acceptable data from the various input devices, such as an acceleration pedal.
This is like having a program running that is supposed to only act on input digits (0 through 9) and blows up every time a letter (A through Z) or some other symbol (@, #, &, etc.) is typed in. A competent programmer will put code that ignores all the other non-numerical data, which will prevent these accidental program blowups, especially if it is a matter of saving lives going out of control at 120 MPH.
It's a little more involved than that. The unit has to be able to be put into a degraded mode. How should the ECU respond to a dead short? Leave the operator stranded on the highway? That wouldn't go over too big either.
You are a software programmer right? So tell me please why the mouse cursor on my monitor begins to move a little every time my cell phone is ringing ( it happens about 3-4 seconds befor my cell rings in case if the cellphone is about 1-2 miters from the computer) That is what they are talking about. Interferense with the law voltage equipment.
Code review based on limited information and making poor decisions. Programmers like this are a dime a dozen and you can outsource their easy job on the drop of a dime. Better programmers are well just more intelligent, that's the biggest thing.
Latchup is a term used in the realm of integrated circuits (ICs) to describe a particular type of short circuit which can occur in an improperly designed circuit. More specifically it is the inadvertent creation of a low-impedance path between the power supply rails of a MOSFET circuit, triggering a parasitic structure which disrupts proper functioning of the part and possibly even leading to its destruction due to overcurrent.
