This electric brake device includes: a brake rotor, a friction member, a friction member operator, an electric motor, and a controller which controls, by controlling the electric motor, a braking force generated as a result of contact between the friction member and the brake rotor. The electric brake device includes a vehicle speed estimator which estimates the speed of the vehicle having the electric brake device mounted thereon. The controller includes a power limiter which limits the power that drives the electric motor. When an estimated vehicle speed, which is the speed of the vehicle estimated by the vehicle speed estimator, is in a determined low-speed range, the power limiter limits the power in accordance with a condition that has been determined such that the maximum power consumption of the electric brake device decreases in accordance with decrease in the estimated vehicle speed.

A driver assistance system has an emergency stop function for a motor vehicle. The motor vehicle has an electric parking brake. A parking-brake operating element is used to activate the electric parking brake. The driver assistance system is designed to activate an emergency stop function in accordance with the actuation of the parking-brake operating element and, as part of the emergency stop function, to perform an autonomous emergency stop driving maneuver for the emergency stopping of the vehicle. The driver assistance system is characterized in that the driver assistance system is designed to activate the emergency stop function only in response to an end of the actuation of the parking-brake operating element.

Systems and methods are provided testing a vehicle braking system. The method includes determining a nominal brake system parameter of the brake system during a braking operation. A first testing brake operation is performed and a first brake system parameter is determined based on the first testing brake operation.
