Abstract: A peripheral image display device is configured to: acquire wheel speeds of a vehicle; determine a slip state or a non-slip state of a wheel of the vehicle based on the acquired wheel speeds; acquire multiple camera images from respective cameras; store, as a past image, the camera image indicating a range in a traveling direction of the vehicle; generate a peripheral image indicating a periphery of the vehicle by synthesizing the camera images, display the peripheral image on a display. In the non-slip state, the peripheral image display device displays a transparent image showing, in a transparent manner, a portion under a floor of the vehicle using the past image selected based on current wheel speeds is. In the slip state, the peripheral image display device deactivates the display of the transparent image.

Abstract: A visual line detection device according to an embodiment includes a detection unit, an acquisition unit, a determination unit, a calculation unit, and a calibration unit. The detection unit detects a visual line direction of a driver in a vehicle. The acquisition unit acquires a running state of the vehicle. The determination unit determines whether or not the running state acquired by the acquisition unit is a gazing state where the driver is gazing at a particular position. The calculation unit calculates a representative value for a detection result of the detection unit in a case where the determination unit determines that the running state is the gazing state. The calibration unit executes calibration for detection of the visual line direction by the detection unit in such a manner that the representative value calculated by the calculation unit is a reference thereof.

Abstract: A vehicle theft detection device includes an inclination detection unit and an operation control unit. The inclination detection unit detects an inclination of a vehicle. The operation control unit detects theft using an output of the inclination detection unit. If it is determined that the vehicle is in a situation where the vehicle will sway during parking, the operation control unit reports information concerning setting of security to a user.

Abstract: An airbag apparatus includes a controller, a prediction unit, and a sampling-period control unit. The controller conducts sampling of acceleration values output from a plurality of acceleration sensors disposed on a vehicle and controls inflation of an airbag based on the sampled acceleration values. The prediction unit predicts a collision direction in which collision with another vehicle would occur. When the prediction unit predicts the collision direction, the sampling-period control unit shortens a sampling period for the acceleration sensor disposed in the predicted collision direction in comparison with sampling period for the other acceleration sensors. After the sampling-period control unit shortens the sampling period, the controller determines whether or not to inflate the airbag, based on the sampled acceleration values output from the acceleration sensor disposed in the predicted collision direction.
