It's not a gas pedal... not a throttle.. what is it?

So, I'm at a loss as to what to call the right side pedal.

I used to call it a gas pedal, but that doesn't make sense in an EV. I've seen some call it a throttle, but while it does have an electronic linkage to a throttle body in a ICE car, there's no such thing in an EV. I also don't think "accelerator (pedal)" works, because I use the same pedal to slow down in 1 pedal mode. I've seen some here call it a "go pedal", but that doesn't work for the same reason that "accelerator" doesn't.

So far, the best I've come up with is the "NotGas" pedal, but labeling something by describing what it isn't seems wrong. It's also a "NotVolume" pedal, a "NotHorn" pedal, etc.

What is it called? A "battery pedal"?

The throttle is the part that throttles electricity from the battery to the motor. The pedal you speak of is part of the throttle assembly. I am fine calling my right pedal, the "throttle" (as opposed to NotGas, wow!).

Since most of us do one pedal driving, go pedal is just wrong. Along that same line, accelerator seems like a fine alternative to throttle because the pedal controls both positive and negative acceleration.

This. Same discussion decades ago with diesels -- not a "gas" pedal and not a "throttle."

However, there were a lot of people who called it a "go pedal."

According to the GM 2023 Bolt owner's manual:
"One-Pedal Driving
With One-Pedal Driving, the accelerator
pedal is used to control the deceleration of
the vehicle to a complete stop.
Completely lifting off the accelerator pedal
results in aggressive deceleration. Partially
lifting off the accelerator pedal allows the
deceleration of the vehicle to be adjusted as
desired."
So they call it an accelerator pedal.
But we all know it really is a variable resistor lever, otherwise known as a compound potentiometer.
I like the phrase "Warp Speed Lever".

Technically both pedals are the Accelerator.

There is no such thing as deceleration. There is only positive or negative acceleration. But most people can't grasp that concept so fake words are invented.

I vote for the Electron Pedal. As that is clearly the right pedal. It either uses or creates electrons and brake clearly indicates what the other one is for.

In that case, both pedals are electron pedals. The pedal commonly called the "brake" pedal also does regen before applying friction brakes...

I guess I'm somewhat old-school from when the left pedal directly connected to the brakes and the right pedal directly connected to the throttle.

It's kind of comical how a modern car trying to simulate the controls of a former generation machine can cause confusion. I wonder how much money EV car makers could save if they abandoned old-school control schemes and just made the controls appropriate for the machine. In that case, the left pedal would be 100% friction brakes and the right pedal would be 100% power or regen.

Must have an engineering mind like mine, since I've wasted time thinking about this. Throttle really doesn't make complete sense in modern ICE either since it's all drive by wire. The pedal position is read by a potentiometer, and that "suggests" to the ECU how much power is called for, and it decides the throttle opening and fuel rate. More of a power request pedal.

As others mentioned, acceleration is any change in speed or direction. Going around a corner is acceleration even if the same speed is maintained. Strangely, we don't call the steering wheel an accelerator.

I think I'm going to stick with the "NotGas" pedal for two reasons: First, it gives it some relation to the "gas pedal" ICE cars have, and second to distinguish it from the "gas pedal" that ICE cars have. :)

Otherwise, I'll have to use "the acceleration/regeneration/power control pedal." (Using the common meaning of acceleration instead of the technically correct one.)

I'm so glad GM didn't try to simulate a clutch in these cars. :D

Accelerator works the best (in my mind). However I have no problem with gas pedal either. Communication is the meeting of meanings so if someone calls it a gas pedal I understand what is meant and do not need to correct them.

After reading all this I believe that this will become a dilemma for the country music song writers in the near future.
I'm sticking with gas pedal because I like saying....hey give it some more gas. It sounds weird to say...hey give it some more electricity.

Another interesting quirk is that no car ever had a "gas" pedal, except perhaps a hydrogen or natural gas powered vehicle. Even then it would have been a potentiometer pedal that the ECU reads to determine how much gas to meter out.

We use "gas" as a shortened version of gasoline, but it's a liquid, not a gas.

So gas pedal never made sense at any time. I'd probably still call it the gas pedal in a hydrogen car though since it provides the input for gas flow.

What is the opposite of Acceleration? One hint, it is not deceleration. Because that is not a thing.
There's no such thing as "cold" or "dark" either, but we still know what people are talking about. Nobody says, "gee, the rate of photon radiation has decreased by orders of magnitude". They just say it's dark out.

An accelerator works for me but perhaps speed controller would be better for those who wish to be more precise, (then necessary).😂
