Abstract

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.

Claims (56)

1. A method for navigating a self-driving vehicle comprising a vehicle processor, the method comprising operating the vehicle processor 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, wherein the prospective vehicle navigation mode comprises a fixed path mode in which the vehicle follows guiding infrastructure installed in the operating environment;

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;

wherein the vehicle further comprises a vehicle drive system and at least one detection sensor for monitoring objects surrounding the vehicle, and adjusting the one or more vehicle attributes comprises one or more of:

decreasing a detection range of the at least one detection sensor; and

controlling the vehicle drive system to increase a travelling speed of the vehicle.

2. The method of claim 1 , wherein in the fixed path mode of operation, the vehicle processor is operable to:

detect, via at least one vehicle sensor coupled to the vehicle processor, a termination point of the guiding infrastructure; and

in response to detecting the termination point, perform at least one of an emergency stop, a controlled stop, or changing to a free form mode.

3. The method claim 1 , wherein a trigger condition associated with the fixed path mode comprises one or more of:

detecting guiding infrastructure in proximity of the vehicle; and

receiving, via a vehicle communication interface coupled to the vehicle processor, a command to follow guiding infrastructure from a fleet management system.

4. The method of claim 1 , wherein the prospective vehicle navigation mode comprises a free form mode of operation in which the vehicle follows one or more of:

waypoints defined in an electronic map of the operating environment; and

a virtual line path defined in an electronic map of the operating environment.

5. The method of claim 1 , wherein a trigger condition of the one or more trigger conditions comprises one or more of:

detecting, via a vehicle sensor coupled to the vehicle processor, an indicator for changing the vehicle navigation mode; and

arriving at a waypoint location defined in an electronic map.

6. The method of claim 5 , wherein the indicator comprises at least one of a physical marker installed in the operating environment, a frequency signal indicator, or an optical signal.

7. The method of claim 1 , wherein after detecting the trigger condition, the method further comprises operating the vehicle processor to:

determine whether to respond to the detected trigger condition based on satisfaction of a response condition, otherwise ignore the detected trigger condition.

8. The method of claim 7 , wherein the response condition comprises one or more of:

determining that the prospective vehicle navigation mode is different than the initial vehicle navigation mode; and

determining that the detected trigger condition applies to a vehicle type associated with the self-driving vehicle.

9. A system for navigating a self-driving vehicle comprising a vehicle processor, the 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, wherein the prospective vehicle navigation mode comprises a fixed path mode in which the vehicle follows guiding infrastructure installed in the operating environment;

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;

wherein the vehicle further comprises a vehicle drive system and at least one detection sensor for monitoring objects surrounding the vehicle, and adjusting the one or more vehicle attributes comprises one or more of:

decreasing a detection range of the at least one detection sensor; and

controlling the vehicle drive system to increase a travelling speed of the vehicle.

10. The system of claim 9 , wherein in the fixed path mode of operation, the vehicle processor is further operable to:

detect, via at least one vehicle sensor coupled to the vehicle processor, a termination point of the guiding infrastructure; and

in response to detecting the termination point, perform at least one of an emergency stop, a controlled stop, or changing to a free form mode.

11. The system of claim 9 , wherein a trigger condition associated with the fixed path mode comprises one or more of:

detecting guiding infrastructure in proximity of the vehicle; and

receiving, via a vehicle communication interface coupled to the vehicle processor, a command to follow guiding infrastructure from a fleet-management system.

12. The system of claim 9 , wherein the prospective vehicle navigation mode comprises a free form mode of operation in which the vehicle follows one or more of:

waypoints defined in an electronic map of the operating environment; and

a virtual line path defined in an electronic map of the operating environment.

13. The system of claim 9 , wherein a trigger condition of the one or more trigger conditions comprises one or more of:

detecting, via a vehicle sensor coupled to the vehicle processor, an indicator for changing the vehicle navigation mode; and

arriving at a waypoint location defined in an electronic map.

14. The system of claim 13 , wherein the indicator comprises at least one of a physical marker installed in the operating environment, a frequency signal indicator, or an optical signal.

15. The system of claim 9 , wherein after detecting the trigger condition, the vehicle processor is further operable to:

determine whether to respond to the detected trigger condition based on satisfaction of a response condition, otherwise ignore the detected trigger condition.

16. The system of claim 15 , wherein the response condition comprises one or more of:

determining that the prospective vehicle navigation mode is different than the initial vehicle navigation mode; and

determining that the detected trigger condition applies to a vehicle type associated with the self-driving vehicle.
