WOW Pre-Collision System Activated

I had much the same thing happen to me a while back. It's an amazing system, isn't it?

 

The system really is incredible. My 17 Prius prevented me from rear-ending a truck after traffic slowed from 70 to 30. I was braking as hard as I could but the car decided I wasn't applying enough force and braked even harder. Glad the system worked for you as well. It just paid for itself.

 

Impressive. You were lucky the driver behind you didn't hit you while doing her same as you (looking over their shoulder for a gap, and accelerating). Or were they in a recent model Toyota too?

The sooner we get all cars communicating with each other the better. Until someone hacks the system of course.

 

If you watch the Energy Monitor when braking, it shows increased recharge. This is because when you hit the brakes, it actually increases recharge rate before it hits the mechanical brakes thus saving the wear and tear on the brake pads. This is the reason why the brakes and pads almost never need to be replaced.

I've seen the BRAKE message myself come on twice since owning my 2017 due to drivers not knowing where they were going.

 

I think that's the last thing you'd want to be looking at in an emergency braking situation. It would all be over so fast anyway.

 

I wonder if there is a maximum that the system will brake when the driver applies force to the pedal, but maybe PCS will exceed that if it senses that a crash is imminent. Perhaps combining maximum regen and maximum friction braking at the same time, of course modulated by ABS.

 

Obviously don't do it when you are in traffic or in an emergency situation. Gotta take the time to notice the behavior of the vehicle when driving it under various conditions to know what is normal and not normal, and what the car's on-board computers do.

 

Pity it has no way of attenuating the persistent nagging lecture from the passenger seat area as well.


Edit: regarding post #1

 

You didn't get the optional muzzle?

 

LOL. I was really referring to the last sentence from OP in #1

 

Awesome! Glad the PCS saved you and yours. Mine has activated too, possibly preventing an accident. The computer reacts faster and more precisely than a human being.

Those comments of "regen braking" are rather superfluous. I'm absolutely sure the "friction brakes" -vastly- out-power the regen braking, and both are limited by tire traction anyway, as already posted. In other words, the Prius doesn't need regen braking in an emergency situation, whether or not it uses it.

 

Regen is antithetical to emergency braking anyway. The skid control system and ABS want to micromanage each wheel in that situation. Since regen is applied centrally from within the HSD, rather than at each wheel like brake pads, it would work against that effort.

 

In my 2010 one would have to be dead to not notice PCS retracting the seat belts. They release after a few seconds.

Perhaps the Cone of Silence is only offered in DC's region and the ejector seat in England.

What?

 

Not on my PCS - it beeped at me this morning, I was in a line of traffic and about to slip through a gap - but the seat belt didn't retract. I've had it apply the brakes, but don't recall it retracting my belt.

Yes, a Cone of (relative) Silence, quietest car I've had.
