An apparatus for message notification displays a message to be known to a driver of a vehicle on a display disposed in front of a driver's seat on which the driver is sitting, when a change in environment around the vehicle causing the driver to turn his/her attention forward, an action of the vehicle that the driver can sense, or operation by the driver of a vehicle-mounted device in a front area of the vehicle is detected, in the case where travel of the vehicle is controlled in autonomous driving mode in which driving operation by the driver is unnecessary, and where a looking direction of the driver is not a direction related to the driving operation.

Apparatus and method for message notification

An other-vehicle detection apparatus includes: a sound source device mounted on a first vehicle and configured to output a non-audible region sound of a predetermined frequency range set in advance; a sound collection device mounted on the first vehicle and configured to collect sound information around the first vehicle; and a distinction device configured to distinguish a second vehicle based on a non-audible region sound included in the sound information collected by the sound collection device of the first vehicle.

Other-vehicle detection apparatus, driving assistance apparatus, and other-vehicle detection method

An approaching vehicle detection apparatus includes: a sound information detection unit configured to detect sound information around an own vehicle; a sound source detection unit configured to detect a sound source around the own vehicle based on the detected sound information; an approaching vehicle determination unit configured to determine whether the sound source is a vehicle approaching the own vehicle; and a vehicle state changing unit configured to change a vehicle state of the own vehicle to a vehicle state where the own vehicle sound is able to be suppressed when the own vehicle sound generated from the own vehicle is able to be suppressed by changing the vehicle state of the own vehicle.

Approaching vehicle detection apparatus and drive assist system

To provide a vehicle information transmitting device capable of resolving the bothersome that occurs when the light is strong. According to the present embodiment, a plurality of light sourcesis arranged in an array form of plural rows or plural columns in the light source panelso that light can be irradiated in a horizontal direction (right and left direction) and vertical direction (height direction, up and down direction). The light source panelincludes a diffusion plateand a shaft memberfor entirely or partially adjusting the transmitting degree (blurring degree of light) of the light of the light sourcein association with the arrangement position of the light source, and a plurality of springsthat plays the role of a fail safe for maintaining the distance between the light sourceand the diffusion platein a maximum state at the time of malfunctioning.

Vehicle information transmitting device

To provide a driving assistance apparatus that can detect an intersection at which driving assistance is required with a high degree of precision so that the driving assistance can be provided more appropriately, a driving assistance apparatusincludes: a vehicle speed acquisition unitthat obtains information indicating a vehicle speed of a vehicle; an assistance condition determination unitthat determines whether or not an assistance activation condition, which is a condition for providing a driver of the vehiclewith driving assistance, is satisfied on the basis of whether or not a vehicle speed V obtained by the vehicle speed acquisition unitis equal to or lower than a reference vehicle speed V1, and on the basis of information relating to an intersection or a preceding vehicle in front of the vehicle; and an assistance execution unitthat executes, as the driving assistance, assistance including at least one of warning issuance to the driver, braking control, and steering control when the assistance condition determination unitdetermines that the assistance activation condition is satisfied.

Driving assistance apparatus

Disclosed is a blind spot display device which enables a driver to check the image of a blind spot area at required timing and can prevent the visual distraction of the driver due to display of unnecessary images, ensuring that the driver is sufficiently attentive during driving. On the basis of the traveling state of a vehicle estimated by a traveling state estimation section, a right display and a left display switch display and non-display of the image of the blind spot area, and the right attention drawing section or the left attention drawing section corresponding to the display displaying the image draws the attention of the driver. On the basis of the traveling state, the image is displayed only when necessary, and is not displayed when unnecessary.

Blind spot display device and driving support device

There is provided a drinking level detecting system and a drinking level detecting method capable of improving the detection accuracy of the drinking level by allowing a third person to correct the drinking level of a driver. In a system or method which detects the drinking level of a driver of a vehicle, the drinking level of the driver is detected by an alcohol detector or the like, and the detection result is corrected by a third person other than the driver when there is an error in the detection result. Accordingly, even when the drinking level detected by the alcohol detector or the like is incorrect, the drinking level can be corrected after ensuring reliability by the determination by the third person.

Drinking level detecting system and drinking level detecting method

An object detecting device scans an image captured by a camera from one side close to the vehicle to the other side remote from the vehicle for detection of an obstacle through pattern matching, so that an obstacle that is close to the vehicle and is likely to collide with the vehicle can be detected in a short time. Thus, the driver is informed of the presence of an obstacle having a high risk of collision, earlier than other obstacles located ahead of the vehicle.

Vehicle-installed obstacle detecting system and method using image capturing and scanning

When it is determined that a head light is turned on, the sunset time is calculated. Thus, the frequency of calculating the sunset time is significantly decreased as compared with that of continuously calculating the sunset time, thereby reducing the processing load. Further, as compared with the case where the sunset time is calculated regardless of the time of lighting on, the calculated sunset time can evaluate the time of lighting on appropriately.

Information processing apparatus

An image display apparatus includes a camera, a laser radar, a depression angle correction calculation device, a three-dimensional object detection device, and a viewpoint conversion device, which are installed in a vehicle. The laser radar detects changes in the condition of a road surface with respect to the camera. The depression angle correction calculation device adds a correction angle to a depression angle of the camera. The viewpoint conversion device reduces the correction angle if the change in road surface condition detected by the laser radar is due to a three-dimensional object detected by the three-dimensional object detection device.
