Patent Images
1. A vehicle communication system comprising:
- a host vehicle two way communication device configured to conduct short range communications in a host vehicle broadcast area surrounding a host vehicle equipped with the vehicle communication system;
an omni-directional antenna operatively coupled to the host vehicle two way communication device to conduct short range communications in the host vehicle broadcast area surrounding the host vehicle;
a bi-directional antenna operatively coupled to the host vehicle two way communication device to conduct short range communications in the broadcast area surrounding the host vehicle;
a vehicle positioning component configured to determine a host vehicle position of the host vehicle;
a vehicle map component including road data with roads being classified by at least one of a road segment attribute; and
a vehicle broadcast power modulating component configured to selectively vary broadcast power of the omni-directional antenna and broadcast power of the bi-directional antenna based on the road segment attribute of a road on which the host vehicle is traveling on as determined by the vehicle positioning component.

Abstract
A vehicle communication system is provide with a host vehicle two way communication device, an omni-directional antenna, a bi-directional antenna, a vehicle positioning component, a vehicle map component and at least one of a vehicle broadcast power modulating component and a bidirectional antenna aiming component. The vehicle map component includes road data with roads being classified by at least one of a road segment attribute. The vehicle broadcast power modulating component selectively varies broadcast power of the omni-directional antenna and broadcast power of the bi-directional antenna based on a road segment attribute of a road on which the host vehicle is traveling on as determined by the vehicle positioning component. The bi-directional antenna aiming component aims the bi-directional antenna based on at least one of traffic information received by the communication device and the road segment attribute of the road on which the host vehicle is traveling on.
