Abstract: A vehicle driving assistance system capable of providing a driver of a vehicle with appropriate driving assistance when the vehicle is approaching an intersection. If a traffic signal includes multiple aspects that are in accord with the directions of traffic movement at an intersection, an identifier determines whether an intended direction of movement (an intention to turn right or left) at the intersection has been received from a driver through an identifying device. If the identifier has received an intended direction of movement, an aspect (a right-turn or left-turn arrow aspect) for which assistance is provided through communication by a reporter is identified. The reporter then assists the right or left turn of the vehicle for the intersection in step S7. If the identifier does not receive an intended direction of movement from the driver, the reporter assists only a straight-ahead movement of the vehicle in step S7.

Abstract: The reception unit receives the traffic light information at least a transition between first and second light colors of a traffic light at an intersection and turn-on times of the first and the second light colors, using a wireless signal received from a server via a transceiver. A position acquisition unit acquires a position of a vehicle. A passing speed range calculation unit calculates a speed range in which the vehicle is allowed to pass through the intersection in accordance with light colors of the traffic light, based on the traffic light information and on the position of the vehicle. The messaging unit outputs a message of driving assistance information including suggestions for deceleration or a passage possibility through the traffic intersection. A vehicle behavior storing unit stores content of the message and a behavior of the vehicle corresponding to the content of the message in a behavior memorizing unit.

Abstract: In order to acquire echo sound information about a long-distance target, an active sonar comprises a fan beam transmitter, a fan beam receiver, a propagation path calculator, a path time calculator, and a horizontal distance calculator. The active sonar transmits a plurality of transmitted fan beams horizontally wide and vertically narrow, and the elevation angles of them are mutually deferent, and receives received fan beams vertically wide and horizontally narrow. The propagation path calculator calculates a propagation path of each of the transmitted fan beams based on the profile of medium and the elevation angle of the transmission. The path time calculator calculates a path time which is the time period from the transmission to the reception. The horizontal distance calculator calculates a horizontal distance from the active sonar to a generation source point of each echo sounds based on the propagation path and the path time.
