Abstract

A brake system includes an electric brake force generator for braking a wheel of a vehicle by a driving force of an electric motor. A problem determination device is provided in which the problem determination device sends an electrical signal to the electric motor such that the electric motor rotates in a direction opposite that of the direction of rotation to generate a brake force. If a rotation of the electric motor is not detected, then the problem determination device determines that a problem has occurred.
