Abstract

A method for controlling an operating mode of a vehicle is presented. The method includes determining a current range of the vehicle while the vehicle is operating in a first operating mode. The method also includes determining a distance to a destination. The method further includes controlling the vehicle to operate in a second operating mode instead of the first operating mode when the range is less than the distance to the destination.

Claims (53)

1. A method for controlling an operating mode of a vehicle, comprising:

navigating to a destination in an autonomous operating mode based on receiving, from a user equipment (UE) associated with a customer, a reservation message that requests a ride to the destination, the reservation message further indicating customer information associated with the customer;

determining a first difference between a current range of the vehicle and a distance to the destination is less than a threshold range value, the threshold range value being greater than zero;

determining a manual operating range associated with a manual operating mode of the vehicle based on the first difference being less than the threshold range value;

determining a second difference between the manual operating range and the distance to the destination is greater than the threshold range value;

determining, via the customer information, whether the customer is authorized to operate the vehicle in a manual operating mode based on the second difference being greater than the threshold range value;

prompting the customer for a confirmation input to change to the manual operating mode if the customer is authorized to operate the vehicle in the manual operating mode; and

controlling the vehicle to autonomously navigate to a charging station based on:

the first difference being less than the threshold range value; and

a failure to receive the confirmation input or the customer being not authorized to operate the vehicle in the manual operating mode.

2. The method of claim 1 , further comprising:

determining a current resource level; and

determining a current resource use, in which the current range is based on the current resource level and the current resource use.

3. The method of claim 2 , in which:

the resource level comprises a current battery level; and

the current resource use comprises a current electrical use of the vehicle.

4. The method of claim 1 , in which the vehicle is operated by a human driver in the manual operating mode.

5. An apparatus for controlling an operating mode of a vehicle, the apparatus comprising:

a memory;

at least one processor coupled to the memory; and

instructions stored in the memory and operable, when executed by the at least one processor, to cause the apparatus to:

navigate to a destination in an autonomous operating mode based on receiving, from a user equipment (UE) associated with a customer, a reservation message that requests a ride to the destination, the reservation message further indicating customer information associated with the customer;

to determine a first difference between a current range of the vehicle and a distance to the destination is less than a threshold range value, the threshold range value being greater than zero;

to determine a manual operating range associated with a manual operating mode of the vehicle based on the first difference being less than the threshold range value;

to determine a second difference between the manual operating range and the distance to the destination is greater than the threshold range value;

to determine, via the customer information, whether the customer is authorized to operate the vehicle in a manual operating mode based on the second difference being greater than the threshold range value;

to prompt the customer for a confirmation input to change to the manual operating mode if the customer is authorized to operate the vehicle in the manual operating mode; and

to control the vehicle to autonomously navigate to a charging station based on:

the first difference being less than the threshold range value; and

a failure to receive the confirmation input or the customer being not authorized to operate the vehicle in the manual operating mode.

6. The apparatus of claim 5 , in which:

execution of the instructions further cause the apparatus:

to determine a current resource level; and

to determine a current resource use; and

the current range is based on the current resource level and the current resource use.

7. The apparatus of claim 6 , in which:

the resource level comprises a current battery level; and

the current resource use comprises a current electrical use of the vehicle.

8. The apparatus of claim 5 , in which the vehicle is operated by a human driver in the manual operating mode.

9. A non-transitory computer-readable medium having program code recorded thereon for controlling an operating mode of a vehicle, the program code executed by a processor and comprising:

program code to navigate to a destination in an autonomous operating mode based on receiving, from a user equipment (UE) associated with a customer, a reservation message that requests a ride to the destination, the reservation message further indicating customer information associated with the customer;

program code to determine a first difference between a current range of the vehicle and a distance to the destination is less than a threshold range value, the threshold range value being greater than zero;

program code to determine a manual operating range associated with a manual operating mode of the vehicle based on the first difference being less than the threshold range value;

program code to determine a second difference between the manual operating range and the distance to the destination is greater than the threshold range value;

program code to determine, via the customer information, whether the customer is authorized to operate the vehicle in a manual operating mode based on the second difference being greater than the threshold range value;

program code to prompt the customer for a confirmation input to change to the manual operating mode if the customer is authorized to operate the vehicle in the manual operating mode; and

program code to control the vehicle to autonomously navigate to a charging station based on:

the first difference being less than the threshold range value; and

a failure to receive the confirmation input or the customer being not authorized to operate the vehicle in the manual operating mode.

10. The non-transitory computer-readable medium of claim 9 , in which the program code further comprises:

program code to determine a current resource level; and

program code to determine a current resource use, in which the current range is based on the current resource level and the current resource use.

11. The non-transitory computer-readable medium of claim 9 , in which the vehicle is operated by a human driver in the manual operating mode.
