I do not like the sound of this, did the pedal go all the way to the floor at the reported here.My brake stopped working a few months ago. It was my foot accidentally touching the accelerator that did it.............:-(

I thought I would try something today.What surprises me is that the power is still applied to the motor when both pedals are pressed, I can see the motor overriding the brake if the brake pedal is only lightly pressed, very worrying.
I'm pretty sure that on my Prius the application of the brake, even lightly, would cut power to the motor and the ICE.
I'm shocked that it does not cut the power to the motor as soon as the brake pedal is even slightly pressed, that's such an obvious thing to put into the programming.What surprises me is that the power is still applied to the motor when both pedals are pressed, I can see the motor overriding the brake if the brake pedal is only lightly pressed, very worrying.

If you pull the parking brake switch up, the brakes will come on (as long as there isn't a fault that would stop it working). It basically throws everything on, it sounds hellish, but it does work.I dunno.... Sadly these days there's no manual brake handle to pull that you can use to stop the car!
This logic only applies when stationary …..Heath and safety has dictated for a long time now that the braking power of a car, must exceed the propulsion power that can be created by the car.
So, should there be a problem and the Go pedal / throttle pedal etc become stuck for some strange reason, then the brakes have to be stronger enough, to reduce the speed of the car, or it just becomes like a run away train.
This holding back of the force generated by the power unit of the car, by holding it stationary with more powerful brakes, is effectively how launch control is achieved.
Build and hold the power, hold it back with the brakes, then release the brakes !.
Fun, but not that good for your car or wallet when repeated on a regular basis.
This was probably regen braking being removed rather than acceleration as you went over the bump. If the car detects bumps regen is reduced presumably for stability as the wheels have lower grip at that moment. Our Leaf does this too.I was coming up to a roundabout and had my foot hovering above the accelerator and letting KERS do the braking. The road surface at the junction had recently been planed as it is due to be resurfaced. As I moved from the tarmac down to the planed surface the car jolted over the bump in the road. My foot must have made contact with the accelerator as the car picked up speed. Luckily I was able to manually brake but it was a bit of a shock.
Could also be the regen letting go as the wheel that was braking slid due to the differential being in the drive train, there's no ABS on regen. I used to get this with the Priuses.I experienced the following scenario last night.

I know that this probably is not what happened with the OP but I thought it was worth mentioning.
