Abstract: A driver abnormality detection device is provided that detects an abnormality sign of a driver at a sufficiently earlier stage before driving actually becomes difficult. The detection device includes a control circuit configured to detect an abnormality sign of a driver based on visual line information from a visual line detector, driving operation information from a driving operation detector, and traveling environment information from a traveling environment information detector. The control circuit is configured to calculate a visual line abnormality degree, a driving operation abnormality degree, and a traveling risk of a vehicle. The control circuit is configured to combine the visual line abnormality degree, the driving operation abnormality degree, and the traveling risk to generate a comprehensive abnormality degree, and detect the abnormality sign of the driver when the comprehensive abnormality degree is a predetermined threshold value or greater.

Abstract: A vehicle gear-shifting control apparatus is equipped with an engine, a motor, an automatic transmission, a friction brake system, and a controller which executes regeneration control and gear-shifting control during deceleration of the vehicle with a braking force to front and rear wheels. The controller increases an input torque of an input shaft according to a downshift so that an accompanying acceleration fluctuation equals a target acceleration fluctuation. When the controller determines an oversteered state during the regeneration control and during a downshift, the controller increases the input torque so that a regenerative braking torque decreases while maintaining a regeneration operation of the motor and, at the same time, the controller causes the automatic transmission to perform the downshift in a state where an amount of increase of the input torque in accordance with the downshift has been increased compared to during a non-determination of the oversteered state.
