Abstract
Systems and methods for preventing an autonomous vehicle from transitioning from an autonomous driving mode to a manual driving mode based on a risk model. The system includes a memory that stores instructions for executing processes for preventing the autonomous vehicle from transitioning the autonomous driving mode to the manual driving mode from based on a risk model. The system also includes a processor configured to execute the instructions. The instructions cause the processor to receive physiological data from a sensor, generate a risk assessment profile based on the physiological data, control an operating mode of the autonomous vehicle based on the risk assessment profile.
Claims20
An automated driving (AD) system comprising:
- a memory that stores instructions for executing processes for preventing an autonomous vehicle from transitioning from an autonomous driving mode to a manual driving mode based on a risk model;
- and
- a processor configured to execute the instructions, wherein the instructions cause the processor to:
- receive physiological data from a sensor,
- generate a risk assessment profile based on the physiological data, and
- control an operating mode of the autonomous vehicle based on the risk assessment profile.
A method comprising:
- receiving physiological data from a sensor;
- and
- controlling an operating mode of the autonomous vehicle based on a risk assessment profile and the physiological data.
A non-transitory computer-readable storage medium containing executable computer program code, the code comprising instructions configured to cause a processor to:
- receive physiological data from a plurality of sensors including an electroencephalograph (EEG) sensors and a camera, the physiological data comprising brainwave activity measured by the EEG sensor and eye movement of the driver monitored by the camera;
- generate a risk assessment profile based on the physiological data, wherein to generate the risk assessment profile, the code further comprises instructions configured to cause the processor to:
- determine a baseline brainwave activity of a driver of the autonomous vehicle,
- compare current brainwave activity of the driver to the baseline activity to determine a mental state of the driver, and
- determine whether the driver is at risk of unsafe driving based on a combination of the mental state of the driver and the eye movement;
- and
- control an operating mode of the autonomous vehicle based on the risk assessment profile by preventing the autonomous vehicle from transitioning from an autonomous driving mode to a manual driving mode when the combination of the mental state and eye movement indicates that the driver is at risk of unsafe driving.
