Information retrieval arrangement
First Claim
1. An information retrieval arrangement for a host road vehicle comprising a driving aid system, the arrangement configured to retrieve information of at least one surrounding road vehicle independent from the host vehicle, surrounding the host vehicle, the arrangement comprising:
- a registration plate reading arrangement comprising a processor and configured to read registration plate information of the at least one surrounding vehicle;
an information retrieving unit comprising a processor and configured to retrieve from a database at least one dimension of the at least one surrounding vehicle, based on the read registration plate information, wherein the at least one dimension of the at least one surrounding vehicle is a physical dimension comprising at least one of a length, width or height of the at least one surrounding vehicle, wherein the at least one dimension is utilized by the driving aid system to perform and/or verify calculations of distance and/or relative speed to the at least one surrounding vehicle;
a surrounding vehicle monitoring unit configured to determine a perception angle of a surrounding vehicle, wherein the perception angle is determined from a perceived dimension of the surrounding vehicle; and
a calculating unit configured to calculate a distance to the surrounding vehicle using the perception angle of the surrounding vehicle and the at least one dimension of the surrounding vehicle retrieved from the database.

10. A method performed by an information retrieval arrangement of a host road vehicle for retrieving information of at least one surrounding road vehicle independent from the host vehicle, the host vehicle comprising a driving aid system, where the arrangement comprises a registration plate reading arrangement comprising a processor, an information retrieving unit comprising a processor, a surrounding vehicle monitoring unit, and a calculating unit, the method comprising:
-
reading registration plate information of the at least one surrounding vehicle, using the registration plate reading arrangement; retrieving from a database at least one dimension of the at least one surrounding vehicle, based on the read registration plate information, using the information retrieving unit, wherein the at least one dimension of the at least one surrounding vehicle is a physical dimension comprising at least one of a length, width or height of the at least one surrounding vehicle; utilizing the at least one dimension to perform and/or verify calculations of distance and/or relative speed to the at least one surrounding vehicle, using the driving aid system; determining a perception angle of a surrounding vehicle, using the surrounding vehicle monitoring unit, wherein the perception angle is determined from a perceived dimension of the surrounding vehicle; and calculating a distance to the surrounding vehicle, using the perception angle of the surrounding vehicle and at least one dimension of the surrounding vehicle retrieved from the database, using the calculating unit. - View Dependent Claims (11, 12, 13, 14, 15)
