Vehicle seat

Filed:2018-06-13Pub:2022-04-12
Applicant:TS TECH CO., LTD.

Provided is a vehicle seat that detects an alertness level of the driver, urges the driver to be alert, and permits the transition from autonomous driving to manual driving when the driver is alert enough for the manual driving. A vehicle seat ( 1 ) configured to be mounted on a vehicle ( 3 ) provided with a vehicle control device ( 5 ) that can be selectively switched from autonomous driving to manual driving comprises: a seat body ( 7 ) configured to support a driver; a seat control unit ( 10 ) configured to communicate with the vehicle control device; an alertness level sensor ( 8 ) provided on the seat body for detecting an alertness level of the driver; and a rousing unit ( 9 ) provided on the seat body for providing a stimulus for urging the driver to be roused, wherein the seat control unit is configured to detect the alertness level of the driver according to a signal from the alertness level sensor upon receiving a start signal that is produced by the vehicle control device when a transition from the autonomous driving to the manual driving is to be initiated, to activate the rousing unit when the alertness level is lower than a first alertness level threshold value, and to permit the vehicle control device to perform the transition from the autonomous driving to the manual driving when the alertness level is equal to or higher than the first alertness level threshold value.
