摘要： A driving assist method includes detecting positional information of a first vehicle, storing the detected positional information, detecting a curve along which the first vehicle travels in accordance with the stored positional information, generating curve information including a curvature of the curve at the detected curve, transmitting the generated curve information from the first vehicle after the vehicle passes the curve, receiving the curve information by a second vehicle, determining a timing to provide the curve information in accordance with the received curve information, and providing the curve information at the determined timing.

摘要： A vehicle-to-vehicle communication apparatus includes a host vehicle information storage unit, a receiver, a provisional information generator, and an output controller. Based on vehicle information received by the receiver, the provisional information generator regards narrow vehicles determined as satisfying predetermined conditions as a single provisional vehicle. One condition is that client vehicles and a host vehicle running on the lane of the same running direction include more than one narrow vehicle. Another condition is that no wide vehicle is in a region formed by line segments connecting the narrow vehicles with one another. The provisional information generator generates provisional information of the provisional vehicle from sets of vehicle information of the narrow vehicles which are regarded as the provisional vehicle. The output controller outputs the provisional information.
