摘要:
An electronic communication unit which is in the form of a sensor and/or actuator unit, including at least a first status information processing module having a status memory unit which stores status information for the communication unit in the form of a status data item (stat), wherein the first status information processing module further includes a masking memory unit connected to the status memory unit and also a status processing element connected to the masking memory unit, wherein the first status information processing module is designed such that at least one status information item from the status data item (stat) is selected by the masking memory unit and the resultant selective status data item (sel-stat) is processed by the status processing element such that the output of the latter provides a short status data item (k-stat) which has a shorter data word length than the selective status data item (sel-stat).
摘要:
Disclosed herein is a communication system having at least one first and a second communication unit, wherein the first communication unit has a counter memory unit which stores a counter value (MSG_CNT), wherein the first communication unit is designed such that at least the occurrence of a first defined communication event prompts the counter value in the counter memory unit to be changed in at least one defined first manner, wherein at least the occurrence of a defined reference event is followed by the counter value in the counter memory unit being changed in at least one defined second manner, wherein at least in the course of a second defined communication event the first communication unit transmits the current counter value in the counter memory unit directly or indirectly to the second communication unit.
摘要:
An electronic communication system including at least first and a second communication units (master, slave) which are connected to one another by means of at least one first data line, wherein the communication system has a data transmission protocol which is designed such that at least one defined communication process comprises the transmission of a synchronization packet (frame sync) and/or of an identification packet (ID) and/or a command packet (CMD) and/or of an address packet (ADDR) from the first communication unit (master) to at least the second communication unit (slave) via at least the first data line.
摘要:
The invention relates to a circuit arrangement of a circuit of an electrically controlled brake force booster, including a first and a second line that supply two potentials to the connections of the actuator, an electronically actuated first switch provided in the first line, a control device that switches the first switch with a first, preferably pulse-width modulated, control signal, and an electronically actuated second switch provided in the second line, wherein the control circuit switches the second switch with a second control signal. A process for testing this circuit arrangement includes the step of testing at least one potential on at least one connection of the actuator when both switches are open.
