Abstract: A vehicle-mounted display apparatus includes a substrate and a sheet-metal holder. The substrate has through-holes penetrating a substrate surface of the substrate. In contrast, the sheet-metal holder includes a guide portion extending upright from a main surface of the sheet-metal holder, and projections projecting from the main surface of the sheet-metal holder and configured to define the position of the substrate with respect to the guide portion by an engagement with the through-holes. In a manufacturing process of the vehicle-mounted display apparatus, the substrate abuts against the guide portion in a state in which the substrate surface is inclined with respect to the main surface of the sheet-metal holder. Subsequently, the substrate rotates about the guide portion until the substrate surface becomes substantially parallel to the main surface of the sheet-metal holder, causing the through-holes and the projections to engage each other.

Abstract: A vehicle control apparatus assists a braking operation by using negative pressure in a negative pressure chamber generated by rotation of an internal combustion engine, automatically stops or restarts the engine if a first or second condition is satisfied, respectively. The apparatus determines whether a braking operation is performed, detects the rotational speed of the engine and the negative pressure in the negative pressure chamber using a negative pressure sensor. When a state has continued over a predetermined time while no braking operation has been detected, and the rotational speed has been over a threshold, the apparatus temporarily determine whether the sensor is abnormal, based on the negative pressure. When the sensor has been temporarily determined abnormal for a predetermined number of times, the abnormality is certainly determined to inhibit automatic stopping of the engine. The predetermined time may be changed depending whether the state has continued.

Abstract: A mobile apparatus obtains a posted data set of a social networking service. The mobile apparatus generates an augmented reality image by superimposing, on a captured image, an icon representing a posted data set posted in an objective capturing range of a camera, based on a posted location of the posted data set, a vehicle location of a vehicle, and a direction of an optical axis of the camera. The mobile apparatus transmits the generated augmented reality image to a vehicle-mounted apparatus. The vehicle-mounted apparatus displays the received augmented reality image on a display. Thus a user who sees the vehicle-mounted apparatus can instinctively understand the posted location of the posted data set.
