Abstract
A heartbeat sensor obtains a heartbeat of a driver. A concentration level computing unit estimates a concentration level of the driver at a time later than a timing of obtaining the heartbeat by the heartbeat sensor, on the basis of the heartbeat obtained by the heartbeat sensor. A state determining unit controls driving assistance for a vehicle on the basis of a comparison of the concentration level of the driver estimated by the concentration level computing unit with a target concentration level of the driver that is set in association with a position or an environment in which the vehicle driven by the driver is predicted to travel.

17. A driving assistance device comprising:
-
a biometric information obtaining unit configured to obtain biometric information of a driver; a driver state estimating unit configured to estimate, on the basis of the biometric information obtained by the biometric information obtaining unit, a state of the driver at a time later than a timing of obtaining the biometric information by the biometric information obtaining unit; and a control unit configured to control driving assistance of a vehicle on the basis of a comparison of the state of the driver estimated by the driver state estimating unit with a condition for the state of the driver that is set in association with any one of a position and an environment in which the vehicle driven by the driver is predicted to travel, wherein the state of the driver is a concentration level of the driver; and wherein the driver state estimating unit, on the basis of the biometric information obtained by the biometric information obtaining unit, estimates a tendency of the concentration level of the driver to decrease over time. - View Dependent Claims (18, 19, 20, 21, 22, 23, 24, 25)
