A vehicular actuation system installed in a vehicle includes an actuation device that includes an operation member manipulated by a vehicle occupant. The system also includes a detecting unit for detecting a three-dimensional image in an operational area of a predetermined range about the operation member. The system also includes a control unit that determines based on the detected three-dimensional image whether or not a palm or back of a hand of the vehicle occupant is present in the operational area. The control unit operates the actuation device when the palm or back of the hand of the vehicle occupant is present in the operational area. The system includes a first operation mode in which the operation member is directly manipulated by the hand of the vehicle occupant to operate the actuation device and a second operation mode in which the actuation device is operated by the control unit.

Vehicular actuation system

An occupant information detection system for detecting information related to a vehicle occupant on a vehicle seat includes an image detecting section facing a vehicle seat area taking a three-dimensional image, an information extraction processing section extracting information related to a three-dimensional surface profile of a detected object on a vehicle seat based on the three-dimensional image, a conversion processing section converting the extracted information into numerical coordinates of a predetermined coordinate system, and a computation processing section deriving a computed value by subtracting an average of first and second coordinate components from a third coordinate component. The system also includes a determination processing section determining the concave-convex shape of a line segment formed by the arbitrary points and the middle point based on the computed value.

Occupant information detection system

An occupant detection apparatus can include a photographing device disposed to face to a vehicle rear seat for taking three-dimensional images; an information extracting section which extracts image information corresponding to an upper area of a seat of the rear seat from three-dimensional images taken by the photographing device; a division processing section which divides information extracted by the information extracting section into areas relating to respective sitting areas for occupants sitting in the rear seat; and a derivation processing section which derives, with regard to histogram showing frequency distribution of picture elements relative to distances from the photographing device, a first histogram corresponding to image information divided by the division processing section and also derives a difference histogram by deriving a second histogram from the derived first histogram, and thus derives information about each rear-seat occupant in each sitting area of said vehicle rear seat based on the difference histogram.

Occupant detection apparatus

An object detecting system, which is installed in a vehicle, uses a camera comprising an optical lens, a distance measuring image chip, and an illumination device to detect information about an object occupying a vehicle seat. The illumination device is sectioned into a plurality of illuminants, such as a first illuminant and a second illuminant, so that the light emitting modes of the illuminants are controlled to be changed individually.

Object detecting system

An object detecting system includes a plurality of photographing mechanisms that are used to detect information about objects inside and outside a vehicle. An object detecting system is installed in a vehicle and comprises a first camera and a second camera to obtain information about objects inside and outside the vehicle. They system further includes a controller for conducting controls to detect information about an object and an electrical power unit to supply electrical power from a vehicle battery to the respective cameras. At least one of the controller and the electrical power unit is shared by the first camera and the second camera.

A technology is provided which is effective for precisely detecting information about a vehicle occupant in a vehicle seat. In one form, an occupant restraint system to be installed in a vehicle is adapted to associate occupant surface profile information relating to a specific body region of a vehicle occupant, which is obtained by a camera for obtaining an image relating to a single view point, with previously stored body information so as to derive body information about the vehicle occupant and varies the occupant restraining mode of an occupant restraint device according to the derived body information.

Occupant information detection system, occupant restraint system, and vehicle

An object detecting system, which is installed in a vehicle, uses a camera comprising an optical lens, a distance measuring image chip, and an illumination device to detect information about an object occupying a vehicle seat. The light emitting mode of a first illuminant and a second illuminant of the illumination device is controlled in such a manner that the quantity of incident light onto the distance measuring image chip is equalized to respective portions in the focusing area.

A seat weight measuring device reduces the temperature difference generated between the resistances of measuring gauges, even when a sudden ambient temperature change occurs. Heat due to ambient temperature is transferred through a column. As a washer interposed between a sensor plate and a nut and a washer interposed between the sensor plate and the column are composed of a material having low heat conductivity and providing electrical insulation, the heat transferred through the column is prevented from being transferred to the sensor plate by the washers. Accordingly, even when the ambient temperature changes suddenly, the temperature difference between the resistances of the strain gauges is reduced. Moreover, the washers provide electrical insulation between the sensor plate and the column.
