Operation support system, sending device, and receiving device
First Claim
1. An operation support system comprising a sending device and a receiving device,the sending device including:
- a situation information acquisition unit configured to acquire information on a situation around the sending device as situation information;
a first communication unit configured to communicate with the receiving device; and
a first control unit configured tomanage a clock time,add clock time information to identify a true clock time, which is associated with the acquired situation information, to the acquired situation information to compose communication information, andcause the first communication unit to transmit the composed communication information to the receiving device, andthe receiving device including;
a notifying unit configured to give notification of information;
a second communication unit configured to communicate with the sending device to receive the communication information from the sending device; and
a second control unit configured tomanage a clock time,make an estimation of situation information at a current clock time from the situation information contained in the received communication information, based on an elapsed time from the true clock time identified by the clock time information contained in the received communication information, andcause the notifying unit to give notification of the estimated situation information.

Abstract
When a map screen is displayed in a navigation system of a subject vehicle, a position of any other vehicle is estimated and is displayed in the map screen. Influence of delay due to the following is eliminated or reduced: time consumed in processing in a navigation system of the other vehicle; time consumed in communication between the navigation system of the other vehicle and the navigation system of the subject vehicle; time from when the navigation system of the subject vehicle receives communication information to when it generates information to be notified; and the like. In cases where the influence of delay is taken into account, as mentioned above, accuracy of a notified position of the other vehicle is enhanced. Thus, an accurate operation support system is provided to minimize occurrence of errors.

13. A method used for an operation support system including a sending device and a receiving device, the method comprising:
-
acquiring information on a situation around the sending device as situation information; managing a clock time in the sending device; adding clock time information to identify a true clock time, which is associated with the acquired situation information, to the acquired situation information to compose communication information; transmitting the composed communication information from the sending device to the receiving device; receiving the communication information in the receiving device; managing a clock time in the receiving device; making an estimation of situation information at a current clock time from the situation information contained in the received communication information, based on an elapsed time from the true clock time identified by the clock time information contained in the received communication information; and giving notification of the estimated situation information.
