Abstract: A driving assistance device for a vehicle includes: an assistance processing portion that executes a notification of a possibility of a host vehicle intersecting with an other vehicle based on host vehicle information including information that provides an estimation of a travelling course of the host vehicle and an other vehicle information including information that provides an estimation of a travelling course of the other vehicle and acquired by wireless communication; and a map acquisition portion that acquires map data including data that specifies a circular intersection. The host vehicle information includes a position of the host vehicle. The assistance processing portion prevents the notification based on the circular intersection, which is disposed in front of the host vehicle in the travelling course of the host vehicle, according to at least the host vehicle information and the map data acquired by the map acquisition portion.

Abstract: An in-vehicle apparatus installed in a first vehicle. The in-vehicle apparatus includes a first distance sensor measuring a distance to an object based on time to receive a reflection wave of an electro-magnetic transmission wave from the object after a transmission of the electro-magnetic transmission wave, with the first distance sensor being an electro-magnetic wave sensor. The in-vehicle apparatus also includes an inclination angle sensor that senses a first vehicle inclination angle representative of an inclination angle of the first vehicle that includes the first distance sensor, a radio communicator that receives a second vehicle inclination angle transmitted from a second vehicle that leads the first vehicle, an angle difference calculator that calculates an angle difference between the first vehicle inclination angle and the second vehicle inclination angle, and a processor that performs a preset operation based on the distance measured by the first distance sensor.

Abstract: A driving assistance apparatus in a subject vehicle includes a driving assistance section. A subject-vehicle estimated trajectory is estimated as a subsequent traveling trajectory from a current position and a traveling orientation of the subject vehicle. A neighboring-vehicle estimated trajectory is estimated as a subsequent traveling trajectory of a neighboring vehicle by acquiring trajectory estimation information. A determination area is designated to include a crossing point included in the subject-vehicle estimated trajectory and the neighboring-vehicle estimated trajectory. It is determined whether the determination area includes an intersection node in road map information. A first driving assistance level is used when the determination area does not include the intersection node; the first driving assistance level is smaller in driving assistance than a second driving assistance level used when the determination area includes the intersection node.

Abstract: A vehicle-mounted device includes an interference determination unit and a sensor control unit. The interference determination unit determines whether an interference state where a first electromagnetic wave ranging sensor equipped to a first vehicle may receive a second transmission wave transmitted from a second electromagnetic wave sensor equipped to a second vehicle is present, based on transmission time frame information received by a first wireless communication device equipped to the first vehicle, and reception duration information indicating a reception duration during which a first electromagnetic wave ranging sensor equipped to the first vehicle may receive a first reflected wave. The sensor control unit controls transmission timing for transmitting the first transmission wave from the first electromagnetic wave ranging sensor and a reception duration, and changes the transmission timing and the reception duration to avoid the interference state, when the interference determination unit determines that the interference state is present.
