A program update system includes a vehicle including a first and second electronic device, and a program transmission device. The program transmission device is configured to communicate with the vehicle and transmit a program for the first electronic device and a program for the second electronic device to the vehicle. The program transmission device transmits an update program for a first electronic device to a second electronic device. The program transmission device transmits a program in a state before the update for backup. The second electronic device updates the program for the first electronic device based on the update program. The second electronic device stores the program in the state before the update.

Program update system, program transmission device, and program transmission method

A communication control system includes a memory and a processor coupled to the memory. The processor is configured to according to an instruction from an external device, perform processing related to changing a network setting on a communication device, after the processing has been executed, determine whether or not communication of the communication device matches a specific communication condition, and notify an error to the external device in a case in which determination has been made that the communication of the communication device does not match the specific communication condition.

Communication control system and communication control method

A program update system includes a vehicle including a first and second electronic devices, and a program transmission device. The program transmission device is configured to communicate with the vehicle and transmit a program for the first electronic device and a program for the second electronic device to the vehicle. The program transmission device transmits an update program for a first electronic device to a second electronic device. The program transmission device transmits a program in a state before the update for backup. The second electronic device updates the program for the first electronic device based on the update program. The second electronic device stores the program in the state before the update.

An in-vehicle control device includes a vehicle-side communication unit installed on a vehicle and communicating with at least an information processing device external to the vehicle, and a first processor. The first processor is configured to: receive an installation request for an application program from the information processing device; in a case in which the installation request has been received, notify the information processing device of a rule defining whether or not a communication frame received at the vehicle-side communication unit is unauthorized and of equipment information related to optional equipment of the vehicle; acquire the application program and a rule that has been updated based on the notified rule and the equipment information from the information processing device; and, in a case in which the updated rule has been acquired, update the rule to the updated rule.

At this time, a communication line load transmission interval deciding unit selects a transmission interval from the load of the bus. An instrument load transmission interval deciding unit selects a transmission interval from the processing loads of at least one of the vehicle on-board instrument and the gateway. A delivery control unit compares the transmission interval selected by the communication line load transmission interval deciding unit with the transmission interval selected by the instrument load transmission interval deciding unit, and performs control so that the divided updating data is delivered at transmission intervals which are equal to or greater than the longer of these transmission intervals.
