Emergency vehicle braking using closed-loop pulsing

A technique controls an electric brake of a vehicle. The technique involves continuously providing power to the electric brake of the vehicle to continuously disengage the electric brake and allow the vehicle to move. The technique further involves, while power is continuously provided to the electric brake and the vehicle is moving, sensing a fault condition.
