First Claim
1. A method for establishing a route for an autonomous vehicle and controlling the vehicle, the method comprising:
- determining localisation information for the vehicle with respect to a first frame of reference by performing a perception process that includes receiving measurements at a measurement interval to localise the vehicle with respect to the first frame of reference, the first frame of reference being a frame of reference that is substantially fixed with respect to a current state of the vehicle;
determining localisation information for the vehicle with respect to a second frame of reference by performing a perception process that includes receiving signals at a signal interval rate to localise the vehicle with respect to the second frame of reference, the second frame of reference being a frame of reference that is substantially fixed with respect to an entity, the entity being different to the vehicle, and the vehicle being moveable with respect to the entity;
establishing a route for the vehicle with respect to the second frame of reference using the localisation information for the vehicle with respect to the second frame of reference;
performing a transformation of the route from the second frame of reference to the first frame of reference, thereby providing a transformed route;
determining a control route for the vehicle with respect to the first frame of reference using the localisation information for the vehicle with respect to the first frame of reference and the transformed route; and
controlling the vehicle to follow the control route as determined from the signal that has been most recently received to localise the vehicle with respect to the second frame of reference;
wherein the measurement interval is less than the signal interval.

Abstract
A method and apparatus for establishing a route for an autonomous vehicle, the method including: determining localization information for the vehicle with respect to a first frame of reference that is fixed with respect to a current state of the vehicle; determining localization information for the vehicle with respect to a second frame of reference that is fixed with respect to an entity (e.g. Earth), the vehicle being moveable with respect to the entity; establishing a route for the vehicle with respect to the second frame using the localization information for the vehicle with respect to the second frame; transforming the route from the second frame to the first frame; and determining a route for the vehicle with respect to the first frame using the localization information for the vehicle with respect to the first frame and the transformed route.

11. Apparatus for establishing a route for an autonomous vehicle and for controlling the vehicle, the apparatus comprising one or more processors programmed to:
-
determine localisation information for the vehicle with respect to a first frame of reference by performing a perception process that includes receiving measurements at a measurement interval to localise the vehicle with respect to the first frame of reference, the first frame of reference being a frame of reference that is substantially fixed with respect to a current state of the vehicle; determine localisation information for the vehicle with respect to a second frame of reference by performing a perception process that includes receiving signals at a signal interval to localise the vehicle with respect to the second frame of reference, the second frame of reference being a frame of reference that is substantially fixed with respect to an entity, the entity being different to the vehicle, and the vehicle being moveable with respect to the entity; establish a route for the vehicle with respect to the second frame of reference using the localisation information for the vehicle with respect to the second frame of reference; perform a transformation of the route from the second frame of reference to the first frame of reference, thereby providing a transformed route; determine a control route for the vehicle with respect to the first frame of reference using the localisation information for the vehicle with respect to the first frame of reference and the transformed route; and control the vehicle to follow the control route as determined from the signal that has been most recently received to localise the vehicle with respect to the second frame of reference; wherein the measurement interval is less than the signal interval. - View Dependent Claims (12)

13. A program or plurality of programs stored on a non-transitory machine readable storage medium, such that when executed by a computer system or one or more processors it/they cause the computer system or the one or more processors to operate in accordance with a method that comprises:
-
determining localisation information for the vehicle with respect to a first frame of reference by performing a perception process that includes receiving measurements at a measurement interval to localise the vehicle with respect to the first frame of reference, the first frame of reference being a frame of reference that is substantially fixed with respect to a current state of the vehicle; determining localisation information for the vehicle with respect to a second frame of reference by performing a perception process that includes receiving signals at a signal interval rate to localise the vehicle with respect to the second frame of reference, the second frame of reference being a frame of reference that is substantially fixed with respect to an entity, the entity being different to the vehicle, and the vehicle being moveable with respect to the entity; establishing a route for the vehicle with respect to the second frame of reference using the localisation information for the vehicle with respect to the second frame of reference; performing a transformation of the route from the second frame of reference to the first frame of reference, thereby providing a transformed route; determining a control route for the vehicle with respect to the first frame of reference using the localisation information for the vehicle with respect to the first frame of reference and the transformed route; and controlling the vehicle to follow the control route as determined from the signal that has been most recently received to localise the vehicle with respect to the second frame of reference; wherein the measurement interval is less than the signal interval.
