Japanese Patent JP7211260
Kind Code:
B2
Abstract:
To suppress fluctuation of bit length by a transmission section and a receiving section for transmitting and receiving a transmission signal.SOLUTION: A transceiver 7 of an ECU 1 includes a transmission section 11, a receiving section 13 and an adjustment section 15. The transmission section 11 changes the potential of a transmission signal in a transmission line 3 to a first level and a second level, according to a transmission signal TXD from a controller 5 changing to a high level and a low level. The receiving section 13 converts a transmission signal in the transmission line 3 into a reception signal RXD changing to a high level and a low level, and outputs the reception signal RXD to the controller 5. The adjustment section 15 measures pulse width of the transmission signal TXD, measures pulse width of the reception signal RXD corresponding to the pulse width of the measurement object, and on the basis of these measurement results, adjusts one or both of the waveform of transmission signal by the transmission section 11, and the waveform of the reception signal RXD by the receiving section 13, so that the difference of pulse width between the transmission signal TXD and the reception signal RXD is small.SELECTED DRAWING: Figure 1
