METHOD FOR THE TRANSMISSION OF DATA USING SELF-DIAGNOSTIC PULSE WIDTH MODULATION |
摘要 |
Disclosed is a method for transmitting data between a master control unit and a slave control unit. According to said method, the master control unit (4) outputs a pulse width-modulated signal (7) at an output terminal (HI_LO_BUS) in order to transmit the same to the slave control unit (5) via a bus (6). The inventive method is characterized by the following steps:-the slave control unit (5) generates an acknowledgement signal at periodic acknowledgement intervals (TQuitt);-the slave control unit (5) influences the pulse width-modulated signal (7) transmitted on the bus (6) during the acknowledgement interval (TQuitt);-the master control unit (4) detects the influenced pulse width-modulated signal (7), the pulse width-modulated signal (7) output at the output signal terminal (HI_LO_BUS) being read back at an input signal terminal (Read_Back_Bus) of the master control unit (4).
