Abstract

This invention intends to reduce a time difference in information collection time as much as possible in a vehicle installed network system for collecting information on distributed positions within a vehicle. According to this invention, information on a measurement result by a sensor (23) at a time point after a previously-defined time elapses since a specified signal transmitted regularly is received is held in a sensor data storage register (49) on a network (21) installed within a vehicle, capable of broadcasting, achieved according to a communication method in which a transmission right is supplied regularly, and the information is transmitted at a time point when the transmission right is obtained on the network (21). In the vehicle installed network system for collecting information on the distributed positions within the vehicle, the time difference in the information collection time can be reduced as much as possible.

Claims

1. A communication control apparatus which holds predetermined information at a time point after a previously-defined time elapses since a specified signal transmitted regularly is received on a network installed within a vehicle, capable of broadcasting, and achieved according to a communication method in which a transmission right is supplied regularly, and transmits the information at a time point when the transmission right is obtained on said network.

2. The communication control apparatus according to claim 1, wherein said predetermined information is information from a sensor.

3. The communication control apparatus according to claim 1, wherein

previously-defined time information which is a timing for collecting said predetermined information is capable of being changed by including time specifying information in the specified signal.

4. The communication control apparatus according to claim 1, wherein

ID information which increases cyclically at every transmission is included in the specified signal, said received ID information and said predetermined information are simultaneously transmitted from an information transmission side, and a host memory address which stores said transmitted predetermined information is changed based on said ID information on an information collection side.

5. The communication control apparatus according to claim 2, wherein

previously-defined time information which is a timing for collecting said predetermined information is capable of being changed by including time specifying information in the specified signal.

6. The communication control apparatus according to claim 2, wherein ID information which increases cyclically at every transmission is included in the specified signal, said received ID information and said predetermined information are simultaneously transmitted from an information transmission side, and a host memory address which stores said transmitted predetermined information is changed based on said ID information on an information collection side.

7. The communication control apparatus according to claim 3, wherein

ID information which increases cyclically at every transmission is included in the specified signal, said received ID information and said predetermined information are simultaneously transmitted from an information transmission side, and a host memory address which stores said transmitted predetermined information is changed based on said ID information on an information collection side.

8. The communication control apparatus according to claim 5, wherein

ID information which increases cyclically at every transmission is included in the specified signal, said received ID information and said predetermined information are simultaneously transmitted from an information transmission side, and a host memory address which stores said transmitted predetermined information is changed based on said ID information on an information collection side.
