Abstract: A control method for a vehicle includes: predicting a position of an eye point of an occupant after a state of a vehicle seat is changed based on amount of adjustment of an adjusting mechanism due to change in state of the vehicle seat; determining whether or not the predicted position of the eye point is located within a measurement range of a camera member installed to a steering member; and if it is determined that the predicted position of the eye point is not located within the measurement range of the camera member, moving the measurement range of the camera member toward the predicted position of the eye point synchronously with the steering member.

Abstract: A feeling monitoring system includes a facial image acquisition portion, a feeling information acquisition section, and a feeling display generation section. The facial image acquisition portion is capable of acquiring a facial image of an occupant individually sitting in each seating position of two or more seating positions in a vehicle. The feeling information acquisition section acquires feeling information representing the feeling of the occupant based on the facial image acquired from the facial image acquisition portion. The feeling display generation section generates a feeling display corresponding to the feeling information acquired by the feeling information acquisition section.

Abstract: A control method for a vehicle includes: predicting a position of an eye point of an occupant after a state of a vehicle seat is changed, based on amount of adjustment of an adjusting mechanism due to change in state of the vehicle seat; determining whether or not a display light reflected on a wind shield is passing through a predicted position of the eye point; and if it is determined that the display light reflected on the wind shield is not passing through the predicted position of the eye point, automatically operating a head-up display system or the adjusting mechanism so as to move one of a traveling path of the display light reflected on the wind shield and the eye point of the occupant toward the other.

Abstract: A current sensor includes: a magneto electric conversion element; and a magnetic field concentrating core applying a magnetic field caused by a measurement object current to the magneto electric conversion element. A planar shape of the magnetic field concentrating core perpendicular to a current flowing direction is a ring shape with a gap. The magneto electric conversion element is arranged in the gap. A part of a conductor for flowing the current is surrounded by the magnetic field concentrating core. The magnetic field concentrating core includes two first magnetic members and at least one second magnetic member, which are stacked alternately in the current flowing direction. Parts of the two first magnetic members adjacent to each other via the one second magnetic member are opposed to each other through a clearance or an insulator.

Abstract: A display device of the present invention is mounted on an automotive vehicle. An obstacle located in front of the vehicle is detected by a camera, and its features including speed, distance, size, etc. are analyzed by electronic circuits. An image showing the features of the front object is outputted from a liquid crystal panel. The outputted image is reflected on the windshield, displaying a virtual image to a driver. The virtual image is displayed in a form of a spot encircling the front obstacle seen through the windshield. The ways of displaying the encircling spot are variously changed according to a degree of collision danger that is determined according to a period in which the vehicle reaches the obstacle. For example, if the degree of collision danger is high, the spot is shown in red-orange color and/or with a high brightness. Thus, the driver easily recognizes the front obstacle in a high degree of collision danger.

Abstract: An information processing system for use in a vehicle includes a main body for various operations and a portable device in data communication with the main body. The portable device is installed in front of a seat, and has a speaker system for outputting an audible signal. A virtually created source of the audible signal whose location or direction relative to the driver and other occupants of the vehicle is identified by the information processing system. A sound field localization based on a data processing for the audible signal makes the sound signal heard from the identified direction. Perception of the audible signal from the virtually created source of the audible signal facilitates awareness of a surrounding environment of the vehicle.

Abstract: An output section, consisting of a pair of loudspeakers disposed adjacently to each other, is installed inside a seatback of a designated seat. Sound output surfaces of respective loudspeakers face a designated person sitting on the designated seat. It is hence easy to secure a required distance for obtaining clear acoustic image localization in accordance with the size of loudspeakers cooperatively constituting the output section.
