METHOD AND DEVICE FOR SYNCHRONIZING A CONTROL UNIT AND AT LEAST ONE ASSIGNED PERIPHERAL UNIT

摘要

In a method for synchronizing a control unit and at least one peripheral unit having actuators and/or sensors, the control unit and the peripheral unit exchange data with each other via a serial interface. The control unit transmits data to the at least one peripheral unit which is processed in the peripheral unit for the operation of the actuators and/or sensors, and at least one synchronization character is transmitted from the control unit to the peripheral unit for the synchronization. In this context, the synchronization character is appended by the control unit to a first data sequence of a data stream to be transmitted from the control unit to the peripheral unit, and the transmission of a second data sequence to be transmitted after the first data sequence is delayed in time on the part of the control unit, so that the second data sequence is transmitted by the control unit to the peripheral unit following the synchronization character.

1. A method for synchronizing a control unit and at least one peripheral unit having actuators and/or sensors, the control unit and the peripheral unit adapted to exchange data with each other via a serial interface, comprising:
transmitting, from the control unit to the peripheral unit, data for operation of the actuators and/or sensors, and at least one synchronization character for synchronization; wherein the transmitting includes:
appending, by the control unit, the synchronization character to a first data sequence of a first data stream to be transmitted from the control unit to the peripheral unit;delaying in time by the control unit, transmission of a second data sequence to be transmitted after the first data sequence, so that the second data sequence is transmitted by the control unit to the peripheral unit following the synchronization character.
