Pedestrian Warning System

Sun Dec 06, 2015 8:36 pm

I read that an "engine sound" audio is supposed to be plainly heard in front of the slowly moving car, to warn pedestrians about the oncoming EV.

As a driver, with windows open, I can't hear anything like this when moving the car slowly forward or backward. People standing by car can't hear it either.

Am I missing a switch setting?

The warning is a "beep, beep beep" sound and is unmissable.
There is no way to turn this off on my car (2015 model) other than by disconnecting the little speaker under the front right bumper.
To search for more details use the term VESS (virtual engine sound system).

My 2016 EV+ (US market) only beeps when in reverse. In both reverse and forward there is a sound I can't describe, sort of like a random growling. The speaker on mine is under the front left fender. I have found some people can't hear it but then their hearing isn't the greatest either.

I've heard it law that all EV's have these sounds at low speeds in US, is this correct?

Not yet, the politicians are still wasting money on getting the law passed. The thing is that some ICEs are just as quiet but they won't have to have the noise maker.

good point. honestly I would not mind at low speed if it made the electric motor "wer' rather than something that sounds like old breakpad on a rusty rotor in my opinion.

I guess I am thankful I do not sound like a forklift or delivery truck backing up.

The sound is not loud in our 16, and it is a very odd sort of chime, not your typical back-up beep. It seems pretty worthless to me, it is not loud enough to really alert anybody if there are any other noises in the environment at all and its not the type of sound that really grabs people's attention.

How often do you hear an ICE in a noisy parking lot start to back up? I rarely do any more. There is too much ambient noise to hear the more modern ICEs. This is what is so ludicrous about requiring a noise maker for EVs. It doesn't matter if you can't hear it, you most likely can't hear and equivalent ICE in the same situation any way.

The comments on the "engine sound" seem to mixed; some have it , some don't ?

I don't have it when moving slowly forward (1-5 mph).

I tried to find a speaker under either front fender. I can't see any items from below, because of closed areas. I was able to see some of the fender cavity looking down from the motor compartment. Looked like a speaker in the front right fender cavity.

I'll check with the dealer when I take it in to fix the 2 recalls.

I did some work recently studying how the blind navigate. The blind are able to hear even quiet engine noise and rely on that when crossing streets. The introduction of hybrids led to a potential problem that they couldn't always hear a car approaching at slow speeds. I don't know if any accidents occurred because of this but it was a concern. I recall some blind advocacy organizations campaigned for adding sounds to hybrid and electric cars. This might be the genesis of this feature.
