US 12,715,475 B1 · Limiting vehicular operation with a faulted component

Abstract

Techniques for enabling operation of a vehicle in one or more different operational states after detecting a fault associated with a component of the vehicle are described herein. A vehicle computing system can monitor components of the vehicle and identify a fault associated with a component. Based on the fault, the vehicle computing system can identify a degraded operational state for the vehicle including one or more limitations or constraints on operation of the vehicle, such as limited speed, acceleration, direction of travel, and/or the like. The vehicle computing system can additionally determine a threshold time period, distance, or range for operating the vehicle in the degraded operational state. The vehicle computing system can cause the vehicle to be controlled according to the limitation(s) or constraint(s) for a time period, distance, or range that is equal to or less than the associated threshold.

Dependent claims

A method comprising:

receiving data associated with a fault of a component of a vehicle operating in an environment;
identifying a degraded state of operation of the vehicle based at least in part on the fault, wherein the degraded state of operation includes a constraint on the operation of the vehicle;
and
causing the vehicle to be controlled based at least in part on the degraded state of operation by:
sending, from a primary controller of the vehicle with a first safety rating, and to a component of the vehicle with a second safety rating that is equal to or less than the first safety rating, an instruction to apply the constraint to vehicle control considerations;
and
applying the constraint to the operation of the vehicle while the vehicle is controlled.

One or more non-transitory computer-readable media storing instructions that, when executed, cause one or more processors to perform operations comprising:

receiving data associated with a fault of a component of a vehicle operating in an environment;
identifying a degraded state of operation of the vehicle based at least in part on the fault, wherein the degraded state of operation includes a constraint on the operation of the vehicle;
and
causing the vehicle to be controlled based at least in part on the degraded state of operation by:
sending, from a primary controller of the vehicle with a first safety rating, and to a component of the vehicle with a second safety rating that is equal to or less than the first safety rating, an instruction to apply the constraint to vehicle control considerations;
and
applying the constraint to the operation of the vehicle while the vehicle is controlled.

A system comprising:

one or more processors;
and
memory storing processor-executable instructions that, when executed by the one or more processors, configure the system to:
receive data associated with a fault of a component of a vehicle operating in an environment;
identify a degraded state of operation of the vehicle based at least in part on the fault, wherein the degraded state of operation includes a constraint on the operation of the vehicle;
and
cause the vehicle to be controlled based at least in part on the degraded state of operation by:
sending, from a primary controller of the vehicle with a first safety rating, and to a component of the vehicle with a second safety rating that is equal to or less than the first safety rating, an instruction to apply the constraint to vehicle control considerations;
and
applying the constraint to the operation of the vehicle while the vehicle is controlled.
