Patent ID: 8626415

Claim:
An electronic brake system ( 50 ) for motor vehicles ( 60 ), comprising at least one wheel brake ( 7 , 8 , 9 , 10 ) which can be activated by an electromechanical actuator ( 11 , 12 ), wherein a first electronic open-loop or closed-loop control unit (WCU) ( 18 , 19 , 20 ), in which a data processing program for performing open-loop or closed-loop control of the electromechanical actuator ( 11 , 12 ) is executed, is assigned to the electromechanical actuator ( 11 , 12 ), and a CAN (Controller Area Network) databus with which the electronic first open-loop or closed-loop control unit (WCU) ( 18 , 19 , 20 ) which is assigned to the electromechanical actuator ( 11 , 12 ) is connected to at least one second central electronic or electrohydraulic open-loop or closed-loop control unit ( 5 ), the loop time of the data processing program for performing open-loop or closed-loop control of the electromechanical actuator ( 11 , 12 ) is configured to be changed via the databus, wherein the first electronic open-loop or closed-loop control unit (WCU) ( 18 , 19 , 20 ) which is assigned to the electromechanical actuator ( 11 , 12 ) includes means for adapting the loop time of the data processing program for performing the open-loop or closed-loop control of the electromechanical actuator ( 11 , 12 ) to the arrival of messages which have a time stamp and are received via the databus, wherein the first electronic open-loop or closed-loop control unit (WCU) ( 18 , 19 , 20 ) is configured to adapt the loop time after comparing an arrival time of a message having a time stamp with a predetermined arrival time window of the loop time of the data processing program in the first electronic open-loop or closed-loop control unit (WCU) ( 18 , 19 , 20 ) associated with the electromechanical actuator.
