A vehicle power supply system includes a first secondary battery, a second secondary battery whose output voltage is lower than that of the first secondary battery, a power conversion device configured to convert an input AC voltage into a DC voltage and output the DC voltage, a battery pack configured to receive the DC power output from the power conversion device and charge the first secondary battery, DC/DC converters configured to step down an input DC voltage to output the stepped-down DC voltage, and a power control unit configured to control the battery pack. The first secondary battery is connected to input ports of the DC/DC converters via the battery pack. An output port of the DC/DC converter is connected to a video media control unit, and the DC/DC converter is provided separately from the video media control unit. An output port of the DC/DC converter is connected to the second secondary battery.

Vehicle power supply system

An external environment recognition device includes: a plurality of external environment recognition sensors each having an information detection unit that detects information of an object outside a vehicle, the plurality of external environment recognition sensors being arranged such that a detection range of the information detection unit includes an overlapping region where at least part of the detection range of the information detection unit overlaps with at least part of the detection range of another one of the information detection units; and a synchronous processing unit that extracts identical objects in the overlapping region from detection results of the external environment recognition sensors, and performs synchronous processing to synchronize the plurality of external environment recognition sensors if there is a deviation in position between the identical objects in the overlapping region.

Outside environment recognition device

In a device () for recognizing an external environment of a moving body, an image processing unit () generates image data indicating the external environment of the moving body. Using this image data, object data indicating an object around the moving body is generated. At an occurrence of a predetermined event, a control unit () records the generated object data in a recording device (), whereas the image processing unit () records, in another recording device (), the image data corresponding to the object data recorded in the recording device (). The time information generation unit () adds the same time information to the recorded object data and image data.

External environment recognition apparatus for mobile body

A vehicle information display deviceincludes: an environment determination unit () that predicts an occurrence of a backward movement of a vehicle based on an output from an environment information acquisition unit, an image processing unit () that receives an image captured by a camera and generates an image to be displayed on a display screen, and a display switching unit that switches a display of a monitor screen provided in a vehicle in accordance with a traveling status of the vehicle. When the environment determination unit () predicts an occurrence of a backward movement, the image processing unit () starts image processing for the backward movement in advance, and When the user performs the backward movement operation, the output image from the image processing unit is displayed on the display screen.

On-vehicle information display device

A vehicle control device includes a plurality of IC units, while maintaining the operational reliability. The vehicle control device includes an IC unit for performing image processing on outputs from cameras; an IC unit for performing recognition processing of an external environment of the vehicle; and an IC unit for performing judgment processing for cruise control of the vehicle. A control flow is provided so as to allow the IC unit to transmit a control signal to the IC units and. The control flow is provided separately from a data flow configured to transmit the output from the cameras, the image data, and the external environment data.

Vehicle control device

A vehicle control device includes: a signal processing IC unit that outputs image processing data; a recognition processing IC unit that performs recognition processing of the external environment of a vehicle to output external environment data obtained through the recognition processing; a judgment processing IC unit that performs judgment processing for cruise control of the vehicle; a power management unit capable of controlling an on or off state of a recognition function of the external environment of the vehicle in the recognition processing IC unit according to the conditions of the vehicle; and a bypass path for enabling data communications from the signal processing IC unit to the judgment processing IC unit without performing the recognition processing of the external environment of the vehicle by the recognition processing IC unit.

A signal processing IC unit performs image processing with respect to an output from a camera. A recognition processing IC unit performs recognition processing based on the output from the signal processing IC unit. A control IC unit outputs a control signal based on the output from the recognition processing IC unit. A first terminal is electrically connected to the recognition processing IC unit. A second terminal is electrically connected to the control IC unit. The signal processing IC unit, the recognition processing IC unit, and the control IC unit are disposed on a board. The first terminal and the second terminal are provided on an edge portion of the board.
