Abstract: A map update system includes a map data storage unit storing therein map data. The map update system acquires a position of a road marking painted on a surface of a road. The map update system acquires a determination value to be subjected to determination of blurring of the road marking based on at least either of measurement information on the road marking and analysis information analyzing the measurement information. The map update system compares the determination value to a reference value and acquires blur information indicating a degree of blurring of the road marking. The map update system reflects the blur information in the map data.

Abstract: A virtual image is superimposed on a foreground scenery of an occupant. It is determined whether a road condition, for associating a display position of the virtual image with a position of an object in the foreground scenery with respect to a road on which the vehicle travels, is satisfied. The virtual image is generated as a superposing virtual image that presents information by associating the display position with the position of the object when the road condition is satisfied. At least a part of the virtual image is generated as a non-superimposing virtual image that presents the information without associating the display position with the position of the object when the road condition is not satisfied.

The virtual image is generated in a first display mode based on the high-precision map information when the high-precision map information can be acquired. The virtual image is generated in a second display mode different from the first display mode based on the low-precision map information when the high-precision map information cannot be acquired.

Abstract: A communication device capable of detecting transmission of an improper message to a network. A CAN controller in the gateway transmits and receives a message attached with a priority level (ID) to/from an ECU through a communication line, and counts, by the consecutive block number counter, the number of transmitted messages that are consecutively blocked as a result of arbitration processing as the number of consecutive blocks and stores the number as the number of allowed blocks into an allowed block number table in the storage unit in association with a priority level attached to the message received at the communication line. Every time a message is received, the controller compares the number of consecutive blocks with the number of allowed blocks for this message, and detects abnormality if the number of consecutive blocks is larger than the number of allowed blocks.

Abstract: In a communication system, an in-vehicle relay device relays data between ECUs, which are each connected to a communication line in a vehicle, by communicating with each of the ECUs. Data received by a communication device from a server outside the vehicle is input to an out-of-vehicle relay device. Data to be transmitted by the communication device to the server is output to the communication device by the out-of-vehicle relay device. The out-of-vehicle relay device relays data between the server and the ECUs by passing data to and from the in-vehicle relay device. The out-of-vehicle relay device outputs, to the in-vehicle relay device, data input to the out-of-vehicle relay device, or associated data that is associated with data that was output. The in-vehicle relay device determines whether the relaying performed by the out-of-vehicle relay device is to be suspended, based on associated data output by the out-of-vehicle relay device.
