Vehicle-to-vehicle communication device and method of controlling the same
First Claim
1. A vehicle-to-vehicle communication device installed on a subject vehicle and organized with one or more vehicle-to-vehicle communication devices as a system, the vehicle-to-vehicle communication device comprising:
- a detection means for detecting first information of the subject vehicle and each of surrounding vehicles around the subject vehicle;
a communication means for receiving second information of surrounding vehicles from another vehicle-to-vehicle communication device;
a report means for reporting various kinds of information;
a signal-processing means for processing the first information of the subject vehicle and of the another communication device and for making the report means report the information of the subject vehicle and each of the surrounding vehicles; and
a map data retrieval means for retrieving map data;
wherein the detection means detects information of positions of the subject vehicle and each of the surrounding vehicles,wherein the report means includes a display means for displaying the various kinds of information as an image,wherein the signal-processing means processes and determines the position of the subject vehicle and the positions of each of the surrounding vehicles based on the information from the detection means of the vehicle-to-vehicle communication devices on the subject vehicle and other vehicles,wherein the signal-processing means controls the display means to display representation of the subject vehicle and each of the surrounding vehicles in an image of the map data when the image is processed by the signal-processing means with the map data retrieved by the map data retrieval means, andwherein the signal-processing means prioritizes the information of positions of the vehicles from plural information sources, when plural sources are available, with accuracy weighting of the sources in processes of position estimation of the vehicles.

Abstract
A vehicle-to-vehicle communication device installed on a subject vehicle includes a detection function, a transmission function, a report function and a signal-processing function to display position information of surrounding vehicles as well as the subject vehicle. In a process of displaying the position information of the vehicles, the device communicates with the devices installed on other vehicles within a reach of the communication function to reflect the position information of the surrounding vehicles including vehicles not equipped with the device.

12. A vehicle-to-vehicle communication device installed on a subject vehicle and organized with one or more vehicle-to-vehicle communication devices as a system, the vehicle-to-vehicle communication device comprising:
-
a detection means for detecting first information of the subject vehicle and each of surrounding vehicles around the subject vehicle; a communication means for receiving second information of surrounding vehicles from another vehicle-to-vehicle communication device; a report means for reporting various kinds of information; a signal-processing means for processing the first information of the subject vehicle and of the another communication device and for making the report means report the information of the subject vehicle and each of the surrounding vehicles; and a map data retrieval means for retrieving map data; wherein the detection means detects information of positions of the subject vehicle and each of the surrounding vehicles, wherein the report means includes a display means for displaying the various kinds of information as an image, wherein the signal-processing means processes and determines the position of the subject vehicle and the positions of each of the surrounding vehicles based on the information from the detection means of the vehicle-to-vehicle communication devices on the subject vehicle and other vehicles, wherein the signal-processing means controls the display means to display representation of the subject vehicle and each of the surrounding vehicles in an image of the map data when the image is processed by the signal-processing means with the map data retrieved by the map data retrieval means, and wherein the signal-processing means determines a type of the representation of each vehicle in the image of the map data based on a condition whether or not each vehicle is equipped with the device.

13. A method of controlling a vehicle-to-vehicle communication comprising the steps of:
-
detecting first vehicle information by a first vehicle; receiving second vehicle information detected by a second vehicle; processing the first vehicle information with the second vehicle information to prepare a report; making the report available to an operator of the first vehicle; retrieving map data; combining the first vehicle information and the second vehicle information with the map data; and displaying the report by an image representing the map data, the first vehicle information and the second vehicle information, wherein the first vehicle information includes vehicle position and related information of the first vehicle and each of surrounding vehicles around the first vehicle, wherein the report includes each of the surrounding vehicles whether equipped with the device, and wherein the step of combining the first vehicle information and the second vehicle information with the map data comprises choosing representations of the vehicles based on an equipment of the device on the vehicles. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21, 22)
