Vehicle communication device
First Claim
1. A vehicle communication device, comprising:
- a plurality of application units for performing inter-vehicle communication in accordance with a predetermined purpose;
a lower protocol unit for transmitting and receiving data between vehicles; and
a middleware unit intervening between said application units and said lower protocol unit, said middleware unit including;
a transfer service processing unit for delivering and receiving data to/from said application units and identifying a delivery destination of data received by said middleware unit;
a communication control service unit for performing a process to avoid congestion in said inter-vehicle communication and managing a port number for identifying said application units; and
a transmission/reception control processing unit for performing a transmitting and receiving control of said data, whereinsaid communication control service unit controls transmission power, transmission interval, and reception sensitivity transmission power in communication of its own vehicle in said process to avoid congestion based on application priority received for each of said application units, vehicle priority of said its own vehicle, and channel usage rate obtained from said lower protocol unit, andsaid communication control service unit exchanges said application priority, said vehicle priority, and said channel usage rate of said its own vehicle between said its own vehicle and said other vehicles, generates congestion avoiding control information including transmission power, transmission interval, and reception sensitivity required to set in said other vehicles, and transmits the congestion avoiding control information to said other vehicles, on the basis of said application priority, said vehicle priority, and said channel usage rate of said its own vehicle, and said application priority, said vehicle priority, and said channel usage rate of said other vehicles being received.

Abstract
A vehicle communication device for using a plurality of applications in an inter-vehicle communication, and performing a control to avoid congestion of its own vehicle and the other vehicles. There is a vehicle communication device including a plurality of application units for performing the inter-vehicle communication, a lower protocol unit for transmitting and receiving data between vehicles, and a middleware unit intervening between said application units and the lower protocol unit. The middleware unit includes a transfer service processing unit, a communication control service unit, and a transmission/reception control processing unit. The communication control service unit controls a congestion avoiding process of its own vehicle and other vehicles based on application priority received for each of the application units, priority for each vehicle, and channel usage rate obtained from the lower protocol unit.
