OSCILLATION REDUCTION UNIT FOR A BUS SYSTEM, AND METHOD FOR REDUCING AN OSCILLATION INCLINATION WHEN TRANSITIONING BETWEEN DIFFERENT BIT STATES

摘要

The invention relates to an oscillation reduction unit (15; 150; 1500) for a bus system (1) and to a method for reducing an oscillation inclination when transitioning between different bit states. The oscillation reduction unit (15; 150; 1500) has two transistors (151, 152) which are arranged anti-serially between a first bus wire (41) of a bus (40) of the bus system (1) and a second bus wire (41) of the bus (40), wherein an exclusive collision-free access of a participant station (10, 20, 30) to the bus (40) of the bus system (1) is at least temporarily ensured in the bus system (1), and a time control block (142) for switching the two transistors (151, 152). The time control block (142) is designed to switch on the two transistors (151, 152) while a signal (CAN_H, CAN_L) on the first and/or second bus wire (41, 42) and/or a transmission signal (TxD), from which the signals on the first and/or second bus wire (41, 42) are generated, changes from a dominant state (402) to a recessive state (41), and the time control block (142) is also designed to switch off the two transistors (151, 152) if the signal (CAN_H, CAN_L) on the first and/or second bus wire (41, 42) and/or the transmission signal (TxD) is/are switched to the recessive state (401).
