Devices that are connected to each other by shorter distances, such as an audio switch 35 and an audio unit 21, the audio switch 35 and a volume control switch 41, a selector switch 43, and an audio mute switch 45 of a left handlebar switch unit 24, and a leveling unit 19 and a meter switch 32, a navigation panel switch 36, and an operation switch 46 of the left handlebar switch unit 24, communicate with each other by way of serial communications. Control units and vehicle-mounted devices which are connected to each other by longer distances, such as a TPMS unit 23, an FIECU 22, and a meter M, and the meter M, a leveling unit 19, a smart unit 23A, and an RVS unit 23B, communicate with each other via a CAN. |

1. A communication control system, comprising:
at least one vehicle-mounted device; at least one control unit configured to control the at least one vehicle-mounted device, wherein said at least one vehicle-mounted device and said at least one control unit comprise vehicle-mounted devices and control units which are connected to each other by a first distance for serial communications with each other, and vehicle-mounted devices and control units which are connected to each other by a second distance for communications with each other via a controller area network (CAN), wherein the first distance is less than the second distance; and a plurality of CAN control units disposed in a meter and belonging to the CAN, each of the CAN control units having different communication rates, wherein said vehicle-mounted devices and said control units are connected to said CAN control units and assigned to respective groups handled by said CAN control units, respectively, depending on the different communication rates, wherein said vehicle-mounted devices and control units, which are connected to each other by the first distance for serial communications with each other, comprise a leveling unit and audio unit that function as hubs, wherein the vehicle-mounted devices and control units, which are connected to each other by the first distance for serial communications with each other, have a lower communication rate of between 75 and 175 Kbps than the vehicle-mounted devices and control units, which are connected to each other by the second distance for communication via the CAN and have a higher communication rate of between 450 and 550 Kbps, wherein said vehicle-mounted devices and control units, which function as hubs, comprise respective line control devices connected to each other, and one of said vehicle-mounted devices and control units which function as hubs comprises a CAN control unit for connection to said CAN, wherein said vehicle-mounted devices and said control units which are mounted on the vehicle comprise at least one of a navigation device, an audio device, a meter device, an engine control device, and a control unit of a smart key device, wherein said vehicle comprises a two-wheeled vehicle or a three-wheeled vehicle, and wherein said one of said vehicle-mounted devices and control units which functions as hubs that comprises a CAN control unit for connection to said CAN and a line control device for communicating between hubs independent of the CAN control unit, is directly connected to one of another said vehicle-mounted devices and control units which function as hubs that does not comprise a CAN control unit for connection to said CAN. |
