Abstract
Systems and methods for controlling a vehicle based on driver engagement are disclosed. In one embodiment, a method of controlling a vehicle includes determining, using driver data from one or more driver sensors, a driver state estimation of a driver of the vehicle, determining, using environment data from one or more environmental sensors, one or more environment anomalies within an environment of the vehicle, and determining an anomaly category for at least one of the one or more environment anomalies. The method further includes, based on the driver state estimation and one or more anomaly categories, selecting a failure mode, based on the failure mode, selecting at least one failsafe action, and determining an operation of the vehicle in accordance with the failure mode.
Claims20
A method of controlling a vehicle, the method comprising:
- determining, using driver data from one or more driver sensors, a driver state estimation of a driver of the vehicle;
- determining, using environment data from one or more environmental sensors, one or more environment anomalies within an environment of the vehicle;
- determining an anomaly category for at least one of the one or more environment anomalies;
- based on the driver state estimation and one or more anomaly categories, selecting a failure mode;
- based on the failure mode, selecting at least one failsafe action;
- and
- determining an operation of the vehicle in accordance with the failure mode.
A system for controlling a vehicle, the system comprising:
- one or more driver sensors for producing driver data;
- one or more environmental sensors for producing environment data;
- one or more processors;
- and
- non-transitory memory storing computer-readable instructions that, when executed by the one or more processors, causes the one or more processors to:
- receive the driver data from the one or more driver sensors;
- receive the environmental data from the one or more environmental sensors;
- determine, using the driver data, a driver state estimation of a driver of the vehicle;
- determine, using the environment data, one or more environment anomalies within an environment of the vehicle;
- determine an anomaly category for at least one of the one or more environment anomalies;
- based on the driver state estimation and one or more anomaly categories, select a failure mode;
- based on the failure mode, select at least one failsafe action;
- and
- determine an operation of the vehicle in accordance with the failure mode.
