SYSTEM AND METHOD FOR MANAGING THE POSITION OF AN AUTONOMOUS VEHICLE
A method for managing the position of a vehicle includes estimating first positions of the vehicle at various times, measuring second positions of the vehicle at these same various times, in the case of a discrepancy between the first and second positions, considering the first positions as current positions of the vehicle at these various times, incrementing a counter when a discrepancy exists between a first position and a second position at the same time, and when the counter reaches a threshold value, placing the vehicle in a safe mode.

13 . A method for managing a position of a vehicle, comprising:
estimating first positions of the vehicle at various times,
measuring second positions of the vehicle at the various times,
when there is a discrepancy between the first and second positions, considering the first positions as current positions of the vehicle at the various times,
incrementing a counter when a discrepancy exists between the first position and the second position at a same time, and
when the counter reaches a threshold value, placing the vehicle in a safe mode.
14 . The method as claimed in claim 13 , wherein the estimating comprises:
combining a longitudinal model and a lateral model of the vehicle in a closed loop so as to calculate subsequent safety states of the vehicle, and
generating safety states of the vehicle.
15 . The method as claimed in claim 14 , further comprising:
storing the safety states of the vehicle.
16 . The method as claimed in claim 13 , further comprising:
producing a synthesis data system to compensate for single or multiple errors in an automated location system of a location system.
17 . The method as claimed in claim 13 , wherein the estimating comprises:
combining a longitudinal model and a lateral model of the vehicle in a closed loop so as to calculate subsequent positions of the vehicle, and
generating safety positions of the vehicle.
18 . The method as claimed in claim 17 , further comprising:
storing the safety positions of the vehicle.
19 . The method as claimed in claim 17 , further comprising:
determining an accuracy ellipse obtained from the safety positions.
20 . The method as claimed in claim 19 , wherein the estimating comprises determining a first, estimated position of the vehicle from the accuracy ellipse, by converging the safety positions.
21 . The method as claimed in claim 20 , further comprising:
comparing a second position with respect to the accuracy ellipse, and
determining that there is a discrepancy when the second position is outside the accuracy ellipse.
22 . A system for managing the position of a vehicle comprising:
means for implementing the method as claimed in claim 13 .
23 . The system as claimed in claim 22 , the system comprising:
an element configured to indicate an error in an automated location system; and
an element configured to activate an emergency braking maneuver when there is an error in the automated location system.
24 . A motor vehicle, comprising:
the system as claimed in claim 22 .
25 . A non-transitory computer data storage medium on which is stored a computer program that, when executed by a computer, causes the computer to execute the method as claimed in claim 13 .
