First Claim
1. A communication system for conducting wireless communication between a first vehicle and a second vehicle, comprising:
- a first communication unit disposed in the first vehicle including a first communication device connected to a first communication terminal;
a second communication unit disposed in the second vehicle including a second communication device connected to a second communication terminal;
a first workload information generating element disposed in the first communication unit, the first workload information generating element determines a first workload information based on a first planned travel route, a first driver'"'"'s current operation, and a correlation between the first planned travel route and the driver'"'"'s current operation;
a second workload information generating element disposed in the second communication unit, the second workload information generating element determines a second workload information based on a second planned travel route, a second driver'"'"'s current operation, and a correlation between the second planned travel route and the second driver'"'"'s current operation information;
a workload state determining element that determines whether a simultaneous low-load period has been received after the first communication unit generates a communication request, the simultaneous low-load period being the first workload information and the second workload information are lower than a predetermined level for a predetermined period of time; and
an incoming call notifying element that notifies the second driver of an incoming call only when the simultaneous low-load period has arrived, wherein when the communication request is transmitted from the first communication terminal to the second communication terminal, the first communication device permits the first communication terminal to transmit the first workload information, and the second communication device uses the workload state determining element to determine whether the simultaneous low-load period arrives, and uses the notifying element to notify the second driver of an incoming call on condition that the simultaneous low-load period has arrived.

Abstract
In a communication system for conducting wireless communication between communication units mounted in vehicles, workload information indicating a workload of a driver of each vehicle is generated. When a communication request for requesting communication is transmitted from the communication unit of a first vehicle, it is determined whether the workload of a driver of the first vehicle and the workload of a driver of a second vehicle are lower than a predetermined level. When the workload of the driver of the first vehicle and the workload of the driver of the second vehicle are determined lower than the predetermined level, an incoming call is notified to the driver of the second vehicle.
