A processing apparatus is a processing apparatus for a vehicle provided with a control processing unit that executes control processing for controlling an operation of an electronic device by executing a first program, and includes: an update determination unit that determines whether or not to update the first program; and a stop determination unit that determines whether or not running of the vehicle is stopped if the update determination unit makes a determination to update the first program, and, if the stop determination unit determines that running of the vehicle is stopped, the control processing unit executes the control processing by executing a second program, and a data amount of the second program is smaller than a data amount of the first program.

Processing apparatus and processing method

In a relay device, a transmitting/receiving unit of an ECU relay receives data. A first counter value is incremented if an amount of data received by the transmitting/receiving unit per unit time exceeds a first threshold. A second counter value is incremented if the amount of data received by the transmitting/receiving unit per unit time exceeds a second threshold. The second threshold is greater than the first threshold. A control unit of a bus relay repeatedly monitors the first counter value. If the first counter value is incremented, the control unit shortens a cycle with which the second counter value is monitored.

Receiving device, monitor and computer program

A communication system includes: a receiving device configured to receive data, and repeatedly set a time range; and a transmitting device configured to repeatedly transmit data to the receiving device at a first time interval, and change a transmission interval at which data is transmitted to the receiving device to a second time interval, which is different from the first time interval, if the number of pieces of data received by the receiving device within the time range is 2 or more.

Communication system, receiving device, transmission interval change method, and computer program

Provided is a program updating device, program updating system, and a program updating method for updating a program without imposing a load on a user. A program updating device ('PUD') includes a communication unit transmitting/receiving information to/from an in-vehicle device operating on a software program, the PUD transmitting update information of a software program from the communication unit to execute update processing, further including: a determination unit configured to determine whether an operation switch of a vehicle has been switched from an on-state to an off-state; a state control unit configured to, if it is determined that the operation switch has been switched to the off-state, instruct to transition to a driving-prohibition state and hold an ignition-on state; and an update processing unit configured to start update processing based on the update information after confirming of a state is made.

Program updating device, program updating system and program updating method

In a communication system, ECUs are connected to a bus. A relay apparatus receives data that was transmitted by one of the ECUs via the bus, and determines, based on the content of the reception, whether or not the power supply from a battery to a transmission source that transmitted the data is to be cut off. If the relay apparatus determines that the power supply to the transmission source is to be cut off, the relay apparatus cuts off the power supply from the battery to the transmission source.

Power supply control apparatus, communication system, and power supply control method

Provided is a small and inexpensive vehicle-mounted apparatus including a first vehicle-mounted device and a second vehicle-mounted device, a small and inexpensive relay apparatus including a first relay device and a second relay device, and computer programs executed by the vehicle-mounted apparatus and the relay apparatus. A relay apparatus includes a first relay device that executes a process in accordance with a first control program and a second relay device that executes a process in accordance with a second control program. A Hardwar Security Module (HSM) of the first relay device verifies the second control program. The second vehicle-mounted device computes associated data pertaining to the second control program. The HSM verifies the second control program by determining whether or not the associated data computed by the second relay device matches reference data.

Vehicle-mounted apparatus, relay apparatus and computer program

A method of manufacturing an optical module includes the steps of applying the invisible light onto the resin member and the optical device, observing, with use of a camera, a part of the resin member located at the optical fiber coupling plane and an image formed at the optical fiber coupling plane by the optical device active layer while applying the invisible light onto the resin member and the optical device, aligning positions of the resin member and the circuit board with respect to each other while observing the part of the resin member located at the optical fiber coupling plane and the image formed at the optical fiber coupling plane, and fixing the resin member to the circuit board while maintaining the aligned positions of the resin member and the circuit board.
