Electric brake system for a motor vehicle

摘要

The invention relates to an electric brake system for a motor vehicle wherein each wheel of the vehicle includes a brake actuator (2) assigned thereto. The invention also relates to a brake actuator for an electric brake system. During a braking operation, the brake linings (20a and 20b) are pressed against the brake disc (30) with a pregiven braking force by a braking-force device (10) of the brake actuator (2). At least one of the brake actuators (2) includes a sensor with which an elastic deformation of the braking-force device (10) or the brake yoke (18) is measured. This elastic deformation occurs during a braking operation. The braking force is determined from the measured elastic deformation and this braking force is then available for the control of the brake system.
