Abstract: An antenna cable noise suppression structure includes a plurality of antenna cables and a noise suppression member that has electrical conductivity and is electrically connected to each of outer conductors of two or more antenna cables. Further, the noise suppression member is electrically connected to an outer conductor of each antenna cable at a position at which a distance from an end of each antenna cable is equal to or less than one quarter of a wavelength calculated based on a frequency of a signal transmitted by each antenna cable. Further, the noise suppression member and the outer conductor that is electrically connected to the noise suppression member are grounded to a grounded portion.

Abstract: An in-vehicle system includes: an autonomous driving system device that is mounted in a vehicle and implements autonomous driving of the vehicle; an autonomous driving controller that is configured to control the autonomous driving system device to perform a control related to the autonomous driving of the vehicle; a first network that connects the autonomous driving system device and the autonomous driving controller with a protocol conversion unit interposed therebetween so as to perform communication with each other by using a plurality of different protocols; and a second network that connects the autonomous driving system device and the autonomous driving controller without the protocol conversion unit interposed therebetween so as to perform communication with each other by using a single protocol.

Abstract: An on-board system includes: a plurality of detectors provided to a vehicle; a controller configured to control an on-board instrument mounted on the vehicle based on detection information indicating a result of detection by each of the detectors; a detector hub interposed between each of the detectors and the controller in an intercommunicatable manner and configured to collect the detection information obtained by the detectors and transmit the collected detection information to the controller; a first network connecting the on-board instrument and the controller in an intercommunicatable manner; and a second network independent from the first network and connecting the detectors, the detector hub, and the controller in an intercommunicatable manner. As a result, the on-board system and the detector hub can achieve appropriate communication.
