Controller area network (CAN) communication device
First Claim
1. A controller area network (CAN) communication device formed such that a plurality of nodes are connected to communication channels in a controller area network, each of the nodes comprising:
- transmission/reception means for transmitting and receiving data including a CAN-ID field formed of bits containing function information;
ID-setting means for setting predetermined function information to the bits of the CAN-ID field contained in the data transmitted from the transmission/reception means; and
ID-analyzing means for analyzing the predetermined function information set in the CAN-ID field included in the data when the data containing the predetermined function information set by the ID-setting means has been received by the transmission/reception means, whereinthe ID-setting means groups the predetermined function information in units of a predetermined function, assigns a data-transmission priority, assigns a general function group ID, and assigns a communication category code ID used to identify a communication content to each item of the grouped predetermined function information to be set to part of the bits of the CAN-ID field.

Abstract
Provided is a control area network (CAN) communication device formed such that a plurality of nodes are connected to communication channels in the CAN. Each of the nodes includes a transmitting/receiving unit for transmitting and receiving data including a CAN-ID field formed of bits containing function information, an ID-setting unit for setting predetermined function information to the bits of the CAN-ID field contained in the data transmitted from the transmission/reception unit, and an ID-analyzing unit for analyzing the predetermined function information set in the CAN-ID field. The ID-setting unit groups the predetermined function information in units of a predetermined function, assigns a data-transmission priority, assigns a general function group ID, and assigns a communication category code ID used to identify a communication content to each item of the grouped predetermined function information to be set to part of the bits of the CAN-ID field.
