Abstract
An in-vehicle relay device includes a controller that is connected to a plurality of electronic controllers mounted on a vehicle via a communication line to relay data transmitted to the communication line. The controller transfers a specific request to the electronic controllers that are transmission targets of the specific request upon receiving the specific request from an external tool connected to a vehicle. The controller sets a communication cycle based on the number of the electronic controllers and a load of a communication line. The controller transfers response data received within a prescribed time to the external tool for each communication cycle upon receiving the response data to the specific request from the electronic controllers.
Claims8
