System and method for road side equipment of interest selection for active safety applications

摘要

In one example, we describe a method and infrastructure for DSRC V2X (vehicle to infrastructure plus vehicle) system. In one example, some of connected vehicle applications require data from infrastructure road side equipment (RSE). Examples of such applications are road intersection safety application which mostly requires map and traffic signal phase data to perform the appropriate threat assessment. The examples given cover different dimensions of the above issue: (1) It provides methods of RSE of interest selection based solely on the derived relative geometric data between the host vehicle and the RSE's, in addition to some of the host vehicle data, such as heading. (2) It provides methods of RSE of interest selection when detailed map data is communicated or when some generic map data is available. (3) It provides methods of RSE of interest selection when other vehicles data is available. Other variations and cases are also given.

1. A method for selecting road side equipment for controlling vehicles in a highway or street, said method comprising:
a central computer receiving a total value which indicates number of road side equipment pieces that a first vehicle is able to receive data from; said central computer determining a type of data a first road side equipment piece transmits or supports; said central computer receiving a location of said first road side equipment piece from an input device; a certification device or module examining security validation of a certificate for said first road side equipment piece; said central computer receiving a location of said first vehicle; said central computer receiving dynamics information about said first vehicle; said central computer receiving a location of a second vehicle near said first vehicle from a location determination device or module; said central computer analyzing said total value which indicates number of road side equipment pieces that said first vehicle is able to receive data from, said type of data said first road side equipment piece transmits or supports, said location of said first road side equipment piece, said security validation of said certificate for said first road side equipment piece, said location of said first vehicle, said dynamics information about said first vehicle, and said location of said second vehicle near said first vehicle; and said central computer selecting said first road side equipment piece based on said analyzing step.
