An improved braking method and system for a vehicle equipped with an anti-lock brake system (ABS), a traction control or anti-slip regulation system (ASR) and one or more additional systems capable of effecting automatic braking of the vehicle independently of driver control, e.g., an adaptive cruise control system (ACC) or a rollover stability control system (RSC). Automatic braking takes place by admission of brake pressure to the drive axle. To detect a simultaneous braking demand of the driver, the wheel speeds of the non-driven axle or axles are compared with the wheel speeds of the drive axle or axles. If the wheel speeds of the non-driven axle(s) are less than the wheel speeds of the drive axle(s), or less than a vehicle reference speed, the brake pressure injected in response to driver demand is also fed to the brake cylinders of the wheels of the drive axle(s).

Vehicle braking method and system

The invention relates to an electric brake system for a motor vehicle wherein each wheel of the vehicle includes a brake actuator (,) assigned thereto. The invention also relates to a brake actuator for an electric brake system. During a braking operation, the brake linings (,and,) are pressed against the brake disc (,) with a pregiven braking force by a braking-force device (,) of the brake actuator (,). At least one of the brake actuators (,) includes a sensor with which an elastic deformation of the braking-force device (,) or the brake yoke (,) 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.

Electric brake system for a motor vehicle

The invention relates to an electric motor having a locking device and a brake actuator for an electric system which includes such an electric motor. The locking brake has a simple configuration and includes a conical ring which is mounted so as to be axially displaceable on the motor shaft of the electric motor of the brake actuator. In a first axial position, the conical ring (26) permits a rotation of the motor shaft (12) in both directions and, in a second axial position, the conical ring is in engagement with the motor shaft (12) and rotates with the latter. In the second axial position of the conical ring (26), a rotation of the motor shaft (12) in one rotational direction leads to the situation that the conical ring (26) is in engagement with the lock ring (24) of the brake actuator (2). The lock ring (24) is fixed so that it cannot rotate relative to the motor shaft (12). In contrast, a rotation of the motor shaft (12) in the other rotational direction leads to the situation that the contact engagement between the motor shaft (12) and the conical ring (26) and between the lock ring (24) and the conical ring (26) is released.

A valve which is formed by a face of a valve body and the outlet area of an opening in a counterpart is disclosed. An extension dipping into the opening to ensure smooth evolution of the beginning of opening operation is known. The opening behavior achieved in this manner is not sufficient for all applications. In order to further smooth the evolution of the beginning of the opening operation, a clearance fit is provided between the extension and the opening which is interrupted by a countersink in the extension or in the opening. The countersink is formed and placed in such a manner that it comprises the counterpart of the clearance fit and at least one inclined control edge and, thereby, an adjustable choke which can be controlled in series with the valve. The countersink can take the form of a groove. Valve arrangements for compressed-air systems in motor vehicles represent a special area of application for the invention.
