SYSTEMS AND METHODS FOR OPERATING ONE OR MORE SELF-DRIVING VEHICLES
The various embodiments described herein generally relate to systems and methods for operating one or more self-driving vehicles. In some embodiments, the self-driving vehicles may include a vehicle processor being operable to: control the vehicle to navigate an operating environment in an initial vehicle navigation mode; monitor for one or more trigger conditions indicating a possible change for the vehicle navigation mode; detect a trigger condition; determine a prospective vehicle navigation mode associated with the detected trigger condition; determine whether to change from the initial vehicle navigation mode to the prospective vehicle navigation mode; and in response to determining to change from the initial vehicle navigation mode to the prospective vehicle navigation mode, adjust one or more vehicle attributes corresponding to the prospective vehicle navigation mode, otherwise continue to operate the vehicle in the initial vehicle navigation mode.
1 . A method for updating an electronic map of a facility using a self-driving vehicle comprising a vehicle processor and at least one vehicle sensor, the method comprising operating the vehicle processor to:
operate a vehicle drive system to navigate the vehicle inside of the facility;
receive sensor data, using the at least one vehicle sensor, in respect of a presence or an absence of guiding infrastructure in the facility;
compare the received sensor data to information stored in the electronic map;
determine a discrepancy between the received sensor data and the electronic map in respect of the guiding infrastructure; and
update the electronic map based on the determined discrepancy.
2 . The method of claim 1 , further comprising operating the vehicle processor to:
determine a location of the vehicle relative to the electronic map; and
update the electronic map at the location.
3 . The method of claim 1 , wherein the at least one vehicle sensor comprises at least one of a light detection and ranging (LiDAR) sensor, a visual sensor, or a magnetic tape sensor.
4 . The method of claim 2 , wherein operating the vehicle processor to determine the discrepancy comprises operating the vehicle processor to determine that the electronic map does not include a representation of guiding infrastructure detected by the vehicle at the location, and
wherein operating the vehicle processor to update the electronic map comprises operating the vehicle processor to add a representation of the guiding infrastructure into the electronic map at the location.
5 . The method of claim 4 , wherein adding the representation into the electronic map, comprises adding one or more graph nodes into the electronic map corresponding to the detected guiding infrastructure.
6 . The method of claim 5 , wherein each graph node comprises data in respect of one or more of:
a pose orientation of the vehicle at the location;
a time-stamp indicating when the discrepancy was detected; or
one or more sensor measurements by the at least one vehicle sensor.
7 . The method of claim 1 , wherein the electronic map is stored on a vehicle memory.
8 . The method of claim 1 , further comprising transmitting an updated electronic map to the fleet management system.
9 . A system for updating an electronic map of a facility using a self-driving vehicle, the system comprising a vehicle processor and at least one vehicle sensor, the vehicle processor being operable to:
operate a vehicle drive system to navigate the vehicle inside of the facility;
receive sensor data, using the at least one vehicle sensor, in respect of a presence or an absence of guiding infrastructure in the facility;
compare the received sensor data to information stored in the electronic map;
determine a discrepancy between the received sensor data and the electronic map in respect of the guiding infrastructure; and
update the electronic map based on the determined discrepancy.
10 . The system of claim 9 , wherein the vehicle processor is further operable to:
determine a location of the vehicle relative to the electronic map; and
update the electronic map at the location.
11 . The system of claim 9 , wherein the at least one vehicle sensor comprises at least one of a light detection and ranging (LiDAR) sensor, a visual sensor, or a magnetic tape sensor.
12 . The system of claim 10 , wherein the vehicle processor being operable to determine the discrepancy comprises the vehicle processor being operable to determine that the electronic map does not include a representation of guiding infrastructure detected by the vehicle at the location, and
wherein the vehicle processor being operable to update the electronic map comprises the vehicle processor being operable to add a representation of the guiding infrastructure into the electronic map at the location.
13 . The system of claim 12 , wherein adding the representation into the electronic map, comprises adding one or more graph nodes into the electronic map corresponding to the detected guiding infrastructure.
14 . The system of claim 13 , wherein each graph node comprises data in respect of one or more of:
a pose orientation of the vehicle at the location;
a time-stamp indicating when the discrepancy was detected; or
one or more sensor measurements by the at least one vehicle sensor.
15 . The system of claim 9 , wherein the electronic map is stored on a vehicle memory.
16 . The system of claim 9 , wherein the vehicle processor is further operable to transmit an updated electronic map to the fleet management system.
