Abstract: A driving assistance control apparatus for a vehicle includes an acquiring unit and a control unit. The acquiring unit acquires a detected traveling environment of the vehicle. Using the acquired traveling environment, and in response to a preceding vehicle being present near a road edge and no obstacle being present between the road edge and the preceding vehicle, the control unit causes a driving assisting unit to perform driving assistance in which the preceding vehicle is tracked.

Abstract: A transmission control device, which drives multiple antennas having different transmission ranges, includes: a genuine transmission control unit that transmits, from a genuine transmission antenna with use of a carrier wave, a genuine code for activating a portable device; and an inversion transmission control unit that transmits, from an inversion transmission antenna with use of a carrier wave, an inversion code including at least partial inverted genuine code concurrently with a transmission of the genuine code from the genuine transmission antenna. The inversion transmission antenna has a transmission range which does not overlap with a transmission range of the genuine transmission antenna.

Abstract: A vehicle control apparatus is mounted in a vehicle and controls the vehicle. The vehicle control apparatus detects an obstacle that is present inside a grade crossing that intersects a traveling course of the vehicle, using a detection result of a sensor that is mounted in the vehicle. The vehicle control apparatus identifies a position and size of the obstacle using a detection result of the vehicle control apparatus, and calculates a clearance in a direction that intersects the traveling course when the vehicle crosses the grade crossing, using the identified position and size of the obstacle. The vehicle control apparatus determines whether the vehicle is able to pass through the grade crossing based on the calculated clearance.

Abstract: A transmission control device is used in an authentication system. The authentication system enables control of an authentication target based on authentication established by verification via wireless communication between the authentication target and a portable device carried by a user. The transmission control device outputs a drive current to a transmission antenna to cause the transmission antenna to transmit a signal having a predetermined frequency band. The transmission control device adjusts the output drive current. The transmission control device detects a current flowing through the transmission antenna.

Abstract: A transmission control device that drives multiple antennas having different transmission ranges controls a genuine transmission antenna among the multiple antennas to transmit, with use of a carrier wave, a genuine code for activating a portable device and a noise determination purpose burst signal for determining a noise in the portable device after the transmission of the genuine code, and controls each antenna of a remaining antenna group, which includes remaining antennas except the genuine transmission antenna, to transmit the noise determination purpose burst signal at a transmission time point, which is set different from one another and shifted from a transmission time point of the noise determination purpose burst signal from the genuine transmission antenna. The transmission ranges of the multiple antennas including the genuine transmission antenna are set to not have a common area.

Abstract: A driving assistance device includes a lane change detection unit, a lane identification unit, a first space determination unit, an operation control unit. The lane identification unit identifies an original lane and a destination lane by using a detection result obtained by a boundary detection unit that detects a first boundary and a second boundary. The first boundary is a boundary between the original lane and the destination lane, and the second boundary is a boundary that defines the original lane and is located on a side opposite to the first boundary. When it is detected that the own vehicle is scheduled to perform a lane change and it is determined that the passable space is present, the operation control unit causes the own vehicle to perform a lateral movement operation before the lane change is performed. The lateral movement operation causes the own vehicle to approach the destination lane.

Abstract: A communication system includes a master node and a slave node connected to the master node via a bus. The master node transmits a header including identification information assigned to a designated function in accordance with a schedule preset individually for the designated function. The slave node has a plurality of functions for each of which a response different from each other is transmitted. The slave node returns the response related to the designated function upon receipt of the header when the designated function assigned with the identification information included in the header is one of the plurality of functions of the slave node.

Abstract: In an apparatus for assisting a turn of a vehicle at an intersection, a turn-signal state detection unit is configured to detect an operating state of a turn signal of the vehicle. A road information detection unit is configured to detect road information that is information regarding a road on which the vehicle is traveling. A determination unit is configured to, using at least one of the detected operating state of the turn signal and the detected road information, determine whether or not the vehicle will make a turn at the intersection.
