The brake system for motor vehicles has a brake pedal unit having a sensor, which has an intelligence of its own in the form of an electronic processing unit, which directly calculates actuating signals for brake actuators. Furthermore, the brake system has a central electronic control unit, which ascertains actuating signals for the actuators on the basis of an analog or digital signal of the mentioned sensor or of an additional sensor. The actuators have an intelligence of their own in the form of an electronic processing unit, which verifies whether the actuating signal coming from the central electronic control unit is valid. If this is the case, then the actuators are controlled by this signal, otherwise on the basis of the actuating signal calculated by the sensor.

Brake system and method for controlling a vehicle brake

A braking system for vehicles, including at least one first brake circuit, and at least one second brake circuit, in which the at least one first brake circuit and the at least one second brake circuit each have an electrical control circuit, which respectively has an electronic control unit and its own power supply device, and brake actuating devices which are activatable by the electronic control units, at least one of the brake actuating devices being activatable by more than one of the electronic control units, in which the brake circuits are electrically activatable via a foot brake valve, and the foot brake valve has two electrical braking transmitter devices which are each connected to the electronic control units so that they are DC-isolated.

Braking system for vehicles, in particular utility vehicles, comprising at least two separate electronic braking control circuits

An angle of rotation sensor includes at least one coil provided with windings and a magnetically conductive element which interacts with the coil is rotatable with a shaft for transmitting a detectable rotational movement, and whose different overlap degree with at least one magnetically conductive body depends on the rotational position thereof. The magnetically conductive element is located outside of a space surrounded by the coil in each rotational position thereof and the magnetically conductive body is U-shaped in such a way that two legs thereof form an intermediate space therebetween and a perpendicular cross web connecting them. The magnetically conductive body includes shaft bearings mounted on the end areas of the legs.

Angle of rotation sensor

A method of determining the angular position of the rotor of a brushless direct current motor having a stator with multi-phase windings, control circuitry that provides excitations switched after one another to the motor phases such that the excitations produce stator flux vectors lying in different directions in the full 360 electrical degree range, and a measurement circuit that delivers responses for the phase excitations is provided. The position is estimated by selecting the main excitation stator flux vector which results in the minimal inductivity shown by the measured response, and selecting the two other vectors in the previous and subsequent directions with respect to the direction of the main vector, and by computing the ratio between differences of measured responses for the selected stator flux vectors.
