A battery control device includes: a charging/discharging control unit; an outside air temperature acquiring unit; and a state-of-charge upper limit setting unit setting a state-of-charge upper limit which is an upper limit of the management range of the state of charge when the acquired outside air temperature is lower than a predetermined air temperature to a low-temperature state-of-charge upper limit which is lower than the state-of-charge upper limit when the outside air temperature is higher than the predetermined air temperature. The battery control device further includes a state-of-charge lower limit setting unit setting a state-of-charge lower limit when the acquired outside air temperature is lower than the predetermined air temperature to a low-temperature state-of-charge lower limit which is lower than the state-of-charge lower limit when the outside air temperature is higher than the predetermined air temperature.

An iris detection device includes a candidate detection unit, a candidate narrowing-down unit, and an iris specifying unit. The candidate detection unit detects circular regions as iris candidates from images captured by an infrared camera. The candidate narrowing-down unit narrows down the detected iris candidates into a predetermined number of iris candidates with use of data items of images of surroundings of each of the iris candidates. The iris specifying unit specifies one of the predetermined number of iris candidates obtained by the narrowing-down as an iris by matching between gradients of a contour of each of the predetermined number of iris candidates and iris templates.

A parking assistance apparatus mounted on a vehicle includes a display processor that displays an image on a right-side display disposed on a right side with respect to a driver, and displays an image on a left-side display disposed on a left side with respect to the driver located in the interior of the vehicle, and a calculator that recognizes boundary lines of a parking area located in the rear of the vehicle, and specifies a gap in a vehicle width direction between the vehicle and one of the boundary lines on each of the left side and the right side to determine a leftward off-center or a rightward off-center. The display processor displays a vehicle off-center image indicating a result determined by the calculator on each of the right-side display and the left-side display together with the image captured.

A driving support apparatus includes an image acquisition that acquires a captured image, a calculator that calculates distance and relative speed between a subject vehicle and a following vehicle, and distances and relative speeds between following vehicles; an evaluator that evaluates a degree of risk caused when the subject vehicle changes a lane to the adjacent lane with respect to the following vehicles on a basis of the distances and the relative speeds; and a display controller that creates support information on the degree of risk associated with a lane change in association with road sections based on positions at which the following vehicles are present, and displays a support image in which a created support information is superimposed on the captured image at a corresponding position on the display portion.

A laser sensor is located close to a rotation axis of a vehicle door and configured to emit a laser beam to a surface of the vehicle door and accept reflected light reflected from an obstacle for scanning a scanning plane shifted in a door-opening direction, in which the vehicle door is openable. A determination section determines whether an obstacle, which is possible to make contact with the vehicle door, exists in the door-opening direction of the vehicle door, based on a result of emission and acceptance of the laser beam of the laser sensor. An opening regulating section regulates an opening of the vehicle door in response to determination of the determination section that the obstacle exists.

An automatic locking system for vehicles includes an electronic control unit. If it is determined that an electronic key is not located in a communication area of an inside-cabin transmitter, the control unit determines whether or not the electronic key is located nearby. As a result, if the electronic key is determined as being located nearby, followed later by a determination that the electronic key is not located nearby, comparison history is stored in a memory. If it is determined that comparison history is stored in the memory and four entry-and-exit doors are closed, the four entry-and-exit doors are locked.

A distance measuring sensor is arranged to a vehicle door, and measures a distance to an object in a direction corresponding to a scanning angle. A memory stores a standard angle and a comparison distance corresponding to the scanning angle. A distance-shortest scanning angle is defined by the shortest value of the measured distance. When the distance-shortest scanning angle is different from the standard angle, the scanning angle is corrected. The object is determined to be an obstacle having a possibility to contact with the door, when the measured distance is equal to or shorter than a corrected comparison distance corresponding to the corrected scanning angle.

Obstacle detecting device

A laser sensor projects laser light in the downward direction. If the laser sensor does not receive any laser light reflected by an obstacle or the ground, it is determined that the obstacle is present in the direction of projection of the laser light. It is thus possible to detect the presence of the obstacle, which will at least affect the opening of the vehicle door.
