Abstract: An on-board update apparatus includes: a communication unit configured to communicate with a first on-board apparatus including a storage unit that stores a program in a rewritable manner and a second on-board apparatus including a sensor that performs detection of a person present around a vehicle and configured to transmit a detection result indicating presence or absence of a person around the vehicle; and a processing unit configured to obtain an update program for updating the program stored in the storage unit from outside, and execute update processing of the program stored in the storage unit using the obtained update program, wherein the processing unit executes update processing of the program stored in the storage unit using the update program, when it is determined that no person is present around the vehicle based on the detection result received through the communication unit.

Abstract: A vehicle-mounted device determination system capable of determining validity of a vehicle-mounted device, and an information collecting device are provided.

Abstract: Provided is a vehicle-mounted relay device that can suppress failures in reading/writing of data due to electric power shortage. The vehicle-mounted relay device determines whether or not reading/writing of data is possible based on the required amount of stored power in the electric power storage device and the remaining amount of stored power in the electric power storage device needed to read/write the data. If the remaining amount of stored power is equal to or greater than the required amount of stored power, there is no risk that the remaining amount of stored power in the electric power storage device may run short before the reading/writing of the data ends. Accordingly, if it is determined that reading/writing of the data is possible, the vehicle-mounted relay device causes an ECU, which is a vehicle-mounted control device, to start reading/writing the data.

Abstract: An in-vehicle communication system and an in-vehicle relay apparatus that can perform relaying between multiple in-vehicle networks if a new in-vehicle device is connected to a said in-vehicle network, and that can prevent, if an improper in-vehicle device is connected to the in-vehicle network, the entire system from being adversely affected by the improper in-vehicle device. The in-vehicle relay apparatus that relays information between the multiple in-vehicle networks has stored therein relay destination determination information necessary to determine a relay destination of information. If a new in-vehicle device is connected to any one of the in-vehicle networks, an acquiring unit communicates with a communication device to obtain updated relay destination determination information, a determination unit determines if the updated relay destination determination information is legitimate, and an updating unit updates the relay destination determination information of the in-vehicle relay apparatus.
