Abstract: A reset signal control apparatus outputs a reset signal to a microcomputer to restrict a malfunction of the microcomputer when the microcomputer is started. The reset signal control apparatus outputs the reset signal to the microcomputer at least until a clock signal provided by an oscillation circuit and based on which the microcomputer operates is stabilized. The reset signal control apparatus includes a power supply section, a measuring section, and an output ending section. The power supply section supplies a power to the oscillation circuit and the microcomputer. The measuring section measures a consumption current of the oscillation circuit and the microcomputer. The output ending section determines that the clock signal provided by the oscillation circuit is stabilized and ends an output of the reset signal to the microcomputer when the consumption current becomes equal to or higher than a predetermined threshold value.

Abstract: When an ECU serving as a communication node is under sleep mode, a switch portion in a transceiver connects a data transmit port of a microcomputer to a memory controller. The microcomputer sends, to the memory controller, a code write-in request for writing a code while outputting a write data that is written as the code. The data transmit port, which is to output a communication data, is commonly used in order to output the write-in request and the write data; this suppresses the increase in the number of connection lines between the microcomputer and the transceiver and the increase in the number of ports of the microcomputer.

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.

Abstract: A communication system having a plurality of communication nodes connected by a communication bus is provided. The system allows at least one non-periodical data message to have a higher priority order than a periodical data message that is transmitted in response to a periodically-transmitted reference message from a master node ECU. In such a manner, a transmission of an urgent non-periodical data message has a higher priority than a transmission of the periodical data message. As a result, a wait time before a start of a transmission of the non-periodical data message is reduced.
