Sensor assembly for a vehicle and multi-circuit braking system having redundant control and rotation rate information communication

A multi-circuit braking system for a vehicle, the multi-circuit braking system comprising:

• a plurality of wheel brakes each arranged on a vehicle wheel of the vehicle;
• a sensor assembly configured to detect at least one physical variable of corresponding wheels that is at least one of rpm-dependent and rotational-speed-dependent;
• a primary controller configured to analyze rotation rate information ascertained for each of the respective vehicle wheels to perform first braking functions of the vehicle;
• a secondary controller configured to analyze the rotation rate information ascertained for each of the respective vehicle wheels to perform second braking functions of the vehicle;
• and
• wherein the sensor assembly includes (i) a rotation rate sensor for each vehicle wheel of the vehicle, each of the rotation rate sensors being configured detect the at least one physical variable of the respective vehicle wheel, the physical variable being used to the ascertain rotation rate information for the respective vehicle wheel and (ii) a respective controller corresponding to each of the respective vehicle wheels, each of the respective controllers being directly connected to the corresponding rotation rate sensor of the respective vehicle wheel and being configured to receive a sensor signal from the corresponding rotation rate sensor and determine the rotation rate information for the respective vehicle wheel from the sensor signal, each of the respective controllers being configured to provide the rotation rate information to a central network over a databus for distribution in the vehicle, each of the respective controllers being configured to provide the rotation rate information directly to the primary controller and the secondary controller via a point-to-point connection,
• wherein at least two of the respective controllers corresponding to the respective vehicle wheels are each electrically connected via an electrical connection to a corresponding actuator of an electric parking brake configured to carry out a parking brake function, the parking brake function being activated in the at least two of the respective controllers corresponding to the respective vehicle wheels via sensor data which is transmitted over the central network and the databus to the at least two of the respective controllers corresponding to the respective vehicle wheels.
