Abstract: A target object position estimation method includes: obtaining frequency distributions representing frequency and intensity for two successive transmission waves; obtaining an intensity distribution representing an intensity on a cell of a combination of a distance relative to a position of a millimeter wave radar and a velocity; generating at least one ranging point by extracting at least one cell having a greater intensity than a predetermined threshold value in the intensity distribution; predicting a type of the target object to which the ranging point belongs; setting a change threshold value in a target area; generating a plurality of ranging points representing positions relative to the position of the millimeter wave radar based on a plurality of cells extracted from the target area and representing greater intensities than the change threshold value; and estimating the position of the target object relative to the position of the millimeter wave radar.

Abstract: Disclosed is a technique of notification control for a vehicle configured to execute automated driving. In the technique, a predetermined operation of the vehicle to be executed in an intersection is identified. A notification related to the predetermined operation is made during automated driving of the vehicle based on the identifying the predetermined operation. The notification prompts a driver of the vehicle to assist in passing the intersection.

Abstract: A semiconductor device includes a semiconductor element, an anisotropic graphite, a first bonding layer, an insulating member, a metal plate, a second bonding layer, and a third bonding layer. The semiconductor element has a chip shape. The anisotropic graphite has one surface to which the semiconductor element is disposed. A direction along the one surface is a c-axis direction of the anisotropic graphite. The first bonding layer bonds the semiconductor element to the one surface of the anisotropic graphite. The insulating member has a plate shape, is disposed across the anisotropic graphite from the semiconductor element, and insulates the anisotropic graphite. The metal plate is made of a metal material, has a plate shape, and is disposed between the anisotropic graphite and the insulating member. The second bonding layer bonds the anisotropic graphite and the metal plate. The third bonding layer bonds the metal plate and the insulating member.

Abstract: An information management system includes a vehicle and a center. The information management system manages information to be provided to an information utilizer from the center. The vehicle obtains external information by using a capture device recognizing a landmark, obtains location information expressing location of the vehicle, and transmits to the center, vehicle information including the external information and the location information. The center receives the vehicle information, obtains calibration information of the capture device by computation using the external information and the location information and a map information database, and records the external information and the location information and the calibration information.

Abstract: A signal processing device includes two to N pieces of AD converters provided independently of one another and each having at least one channel to which the sensor signal is input. The signal processing device is configured to calculate a current sum value as a sum of the N pieces of the converted signals corresponding to currents flowing in and out of the connection point with respect to the converted signals output from the AD converters and, when an absolute value of the current sum value is greater than a determination threshold, determine that any of channels of any of the AD converters is abnormal.
