  • Patent number: 9166910
    Abstract: A first receiver receives an activation signal from a first network and gives the activation signal to an input side of a second transmitter via a first connection line; thereby, the activation signal is sent out via the second transmitter to a second network. Thus, the activation signal is not directly transmitted from the first network to the second network; instead, the activation signal is transmitted by using conversion functions of the first receiver and the second transmitter. This configuration can prevent occurrence of distortion or attenuation in the activation signal. The activation signal from the first network thus enables ECUs belonging to the second network to be activated certainly without delay.
