Abstract
The invention relates to an automatic charging system for charging a vehicle (i) for using an infrastructure delimited by a boundary (100) during a charging period Tc based on GNSS location with guaranteed performance, comprising:
- an onboard receiver wfth integrity guarantee or OBU (30) which, in addition to providing position information, provides additional information relating to the error that can be expected in said position consisting of a health flag (Healthy/Unhealthy), and an RPL or Radial Protection Level, i.e. the amount limiting the horizontal position error according to one direction and with a probability equal to a known value IRX,
- a detection module (70) determining that the vehicle is within the boundary at a moment when all the delimited points of a region comprised by a circle of radius RPL centered on said position are within the boundary, and
- a charging module (70) using the result of the detection module to determine that the vehicle has used the infrastructure during said charging period Tc. The invention also relates to a method of analysis and design of such charging system.
