Ebrake safety

[TLstylin]

Just a random question regarding the ebrake in my 2013 audi s5. The ebrake button is easily accessed by driver or front passenger.

If I'm going 60 mph or something like that and someone accidentally tugs on it will my car suddenly jerk out of control to a stop in the middle of the highway?

I tested the ebrake when going around 3 mph coming to a red light and it abruptly stopped the car.

From what I've heard, pulling the ebrake on the highway will cause emergency braking bring the car to a complete controlled stop, but you have to keep pulling the switch. If you let go of the switch then it releases the brake at higher speeds.

From an Audi website:

Electromechanical parking brake


The electromechanical parking brake comprises the parking brake, starting-off aid and emergency braking functions.

It's activated by pulling a lever on the centre console, which replaces the conventional handbrake lever. When you drive off – provided the driver's seat belt is fastened – the parking brake is released automatically.

The control unit for the electromechanical parking brake determines the selected gear, accelerator position, engine speed, torque, direction of travel and the vehicle’s angle of inclination. It uses this information to prevent the vehicle from rolling back when starting on an incline.

The brake can only be released manually if the foot brake is depressed at the same time. In the event of an emergency braking manoeuvre with the parking brake, the vehicle can be braked considerably more effectively than with a conventional handbrake because the system communicates with the anti-lock braking system (ABS) and electronic brake force distribution (EBD) via the electronic stabilisation programme (ESP).

This is correct, I've tested it when I went ice driving (on a frozen lake), and the car did not spin out of control, and if I let go of the switch, it released the brakes. It will also re-engage all traction control, and take you out of sport mode (if that's where the car settings were configured)

Also, the car won't immediately start braking if you pull it at speed - you have to hold it for a second.
