Seat control device, state estimation device, and non-transitory computer-readable medium

A non-transitory computer-readable medium storing a seat control program for a subject vehicle equipped with a driver monitor to monitor a driver's state, the seat control program configured to control a state of a driver's seat on which a driver is to be seated, the seat control program comprising instructions configured to, when executed by a processor, cause the processor to:

• grasp whether the subject vehicle travels under an automated driving control that does not oblige the driver to monitor surroundings;
• implement a control of a reclining state of the driver's seat when the subject vehicle travels under the automated driving control, such that the driver is included in a detection range of the driver monitor;
• implement the control of the reclining state of the driver's seat, when a transition schedule from the automated driving control to a driving assistance control that obliges the driver to monitor the surroundings is grasped and the driver is not included in the detection range of the driver monitor;
• and
• request posture improvement to the driver such that the driver is included in the detection range of the driver monitor when the transition schedule from the automated driving control to the driving assistance control is not grasped;
• and
• subsequently implement the control of the reclining state of the driver's seat, when the driver is not included in the detection range of the driver monitor.

A state estimation device for a subject vehicle configured to travel under an automated driving control that does not oblige a driver to monitor surroundings, the state estimation device configured to estimate a driver's state and comprising:

• a monitoring state grasping unit configured to grasp, based on a driver captured image acquired by capturing a detection range defined to include at least a head of the driver seated on a driver's seat,
• head information, which relates to a shape of a head in the driver captured image, and
• face information, which relates to parts of a face in the driver captured image;
• and
• a driver state estimation unit configured to, estimate the driver's state by combining the head information and the face information;
• wherein the driver state estimation unit is configured to change weighting of the head information and the face information in estimating of the driver's state between a case in which the vehicle travels under a driving assistance control that obliges the driver to monitor surroundings, and a case in which the subject vehicle travels under the automated driving control.
