Abstract: To effectively determining whether the driver is in the specific state according to the use of the driving assistance device, provided is a driver monitoring device which is applied to a vehicle having a driving assistance device configured to execute a predetermined driving assistance control for assisting the driving of a driver. The driver monitoring device comprising a driver state acquisition unit configured to acquire a state of the driver; and a driver state determination unit configured to determine that the driver is in a specific state when the state of the driver acquired by the driver state acquisition unit satisfies a predetermined condition. The driver state determination unit is configured to relaxes the predetermined condition when the driving assistance device is executing the driving assistance control, as compared with a case where the driving assistance device is not executing the driving assistance control.

Abstract: A driving assist apparatus includes at least one electronic control unit. The at least one electronic control unit is configured to: detect a first object and assist a collision avoidance between a vehicle and the first object existing in a traveling direction of the vehicle; determine whether a first condition that a predetermined number or more of physical objects are detected is satisfied; determine whether a second condition that the vehicle travels at a predetermined speed or lower is satisfied; determine whether a third condition that a predetermined number or more of turning operations of a steering wheel of the vehicle are performed in a predetermined time is satisfied; and determine that a road on which the vehicle is traveling is a crowded environment road, based on a determination that all of the first to third conditions are satisfied.
