In an onboard gateway apparatus, when data is received from one network, the received data is stored in the buffer. The buffer includes a first storage area for storing data in the order of priority of an identifier (ID) attached to the data and a second storage area for storing data in the order in which the data is received. A control means stores the received data in one of the first and second storage areas based on the attached identifier, and sends the data to another network in accordance with the priority of the ID of the data. As to data passing through the first storage area, sending in the order of priority is ensured. As to data passing through the second storage area, sending in the order in which the data is received is ensured.

Vehicle onboard gateway apparatus

A starter drive device which drives a starter motor by, upon actuation of a starter switch, turning a starter relay ON and OFF via an electronic control device, wherein the electronic control device includes: an interface circuit; a power source control circuit; a calculation device and a delay circuit; a buffer; an addition circuit; a latch circuit; a first pull up circuit; a second pull up circuit; and wherein, if the power source control circuit has detected a drop of voltage of the power source when the starter motor is being driven, along with stopping the calculation device, the buffer disconnects the calculation device from the latch circuit, and controls the starter relay by operating the driver circuit via the latch circuit based upon the signals from the interface circuit and the second pull up circuit.
