Abstract

Systems, methods, and non-transitory computer-readable media can determine a trajectory for a vehicle, the trajectory associated with a predicted path to be traveled by the vehicle. A power optimization plan is generated for the vehicle based on the trajectory. One or more power management settings are modified based on the power optimization plan.

First claim

What is claimed is:

1. A computer-implemented method comprising:
determining, by a computing system of a vehicle, a detected change in an environment external to the vehicle based on sensor data of the environment captured by one or more sensors of the vehicle while the vehicle is operating under one or more power management settings;
generating, by the computing system of the vehicle, a trajectory for the vehicle in the environment, wherein the trajectory is generated using the detected change in the environment that is based on the sensor data;
generating, by the computing system of the vehicle, a power optimization plan for the vehicle based on the trajectory; and
modifying, by the computing system of the vehicle, the one or more power management settings based on the power optimization plan.

2. The computer-implemented method of claim 1 , wherein the modifying the one or more power management settings comprises engaging or disengaging at least one of: a gas engine, an electric motor, or a magnetic regenerative brake on the vehicle.

3. The computer-implemented method of claim 2 , wherein the trajectory comprises a plurality of positions to be traveled by the vehicle and the one or more power management settings are modified along one or more positions of the plurality of positions.

4. The computer-implemented method of claim 1 , wherein the detected change includes an obstacle and the generating the trajectory for the vehicle is generated to avoid the obstacle.

5. The computer-implemented method of claim 1 , wherein the trajectory comprises:
a plurality of positions defining a predicted path to be traveled by the vehicle,
a predicted velocity for the vehicle for each position of the plurality of positions, and
a predicted acceleration for the vehicle for each position of the plurality of positions, wherein the predicted velocity for the vehicle for at least one position of the plurality of positions and the predicted acceleration for at least one position of the plurality of positions correspond to an updated velocity and an updated acceleration with respect to an original velocity and an original acceleration of an original predicted path.

6. The computer-implemented method of claim 5 , wherein the trajectory further comprises a time interval for the vehicle for each position of the plurality of positions and the time interval for the vehicle for at least one position of the plurality of positions corresponds to an updated time interval with respect to an original time interval of the original predicted path.

7. The computer-implemented method of claim 1 , further comprising determining a route to be taken by the vehicle, wherein the generating the power optimization plan for the vehicle comprises generating the power optimization plan for the vehicle based on the trajectory and the route.

8. The computer-implemented method of claim 7 , wherein the route comprises a plurality of positions, and the power optimization plan comprises a power management determination to be applied at a particular position of the plurality of positions.

9. The computer-implemented method of claim 1 , further comprising identifying semantic map information for the trajectory to be taken by the vehicle, wherein the generating the power optimization plan for the vehicle comprises generating the power optimization plan for the vehicle based on the trajectory and the semantic map information.

10. The computer-implemented method of claim 1 , further comprising:
modifying the trajectory for the vehicle based on the power optimization plan.

11. A system of a vehicle comprising:
at least one processor; and
a memory storing instructions that, when executed by the at least one processor, cause the at least one processor to perform:

generating a trajectory for the vehicle in the environment, wherein the trajectory is generated using the detected change in the environment that is based on the sensor data;
generating a power optimization plan for the vehicle based on the trajectory; and
modifying the one or more power management settings based on the power optimization plan.

12. The system of claim 11 , wherein the modifying the one or more power management settings comprises engaging or disengaging at least one of: a gas engine, an electric motor, or a magnetic regenerative brake on the vehicle.

13. The system of claim 12 , wherein the trajectory comprises a plurality of positions to be traveled by the vehicle and the one or more power management settings are modified along one or more positions of the plurality of positions.

14. The system of claim 11 , wherein the detected change includes an obstacle and the generating the trajectory for the vehicle is generated to avoid the obstacle.

15. The system of claim 11 , wherein the trajectory comprises:
a plurality of positions defining a predicted path to be traveled by the vehicle,
a predicted velocity for the vehicle for each position of the plurality of positions, and
a predicted acceleration for the vehicle for each position of the plurality of positions, wherein the predicted velocity for the vehicle for at least one position of the plurality of positions and the predicted acceleration for at least one position of the plurality of positions correspond to an updated velocity and an updated acceleration with respect to an original velocity and an original acceleration of an original predicted path.

16. A non-transitory computer-readable storage medium including instructions that, when executed by at least one processor of a computing system of a vehicle, cause the computing system of the vehicle to perform a method comprising:
