Abstract
An in-vehicle communication system includes a control unit which locates coupling points of each one of active speaker units to in-vehicle network. The plurality of the active speaker units includes a plurality of acoustic characteristics set data and programs for determining their own addresses. The respective active speaker units thus can be coupled to in-vehicle network without changing their software, and acoustic characteristics values in response to their coupling points in the vehicle can be established.
Claims8
An in-vehicle communication system comprising:
- a plurality of active speaker units, a control unit, and a given in-vehicle network to which the active speaker units and the control unit are coupled,
- wherein the control unit includes:
- a program for locating coupling points of respective active speaker units at the in-vehicle network;
- and
- a program for notifying the speaker units of their coupling points at the vehicle through a given method,
- wherein the plurality of active speaker units includes:
- a plurality of acoustic characteristics set data;
- a program for determining and setting acoustic characteristics set values based on the coupling points;
- a group address common to the active speaker units;
- and
- a program for implementing communications between the active speaker units, determining tentative addresses recognizable between the active speaker units through a given method, and storing the tentative addresses as their own addresses.
