Abstract: An information providing apparatus includes a traffic information database and a data processing device. The data processing device detects, based on the traffic information data, an impediment event. The data processing device extracts the impediment event potentially encountered by an assisted vehicle. The data processing device calculates, based on the traffic information data, a certainty level of the impediment event. The data processing device provides a driver of the assisted vehicle with a straightforward notification regarding the impediment event potentially encountered by the assisted vehicle and having the certainty level equal to or higher than a straightforward notification threshold. The data processing device provides the driver with an euphemistic notification, which is different from the straightforward notification, regarding the impediment event potentially encountered by the assisted vehicle and having the certainty level less than the straightforward notification threshold.

Abstract: A vehicle speed control device performs vehicle speed control for controlling the vehicle speed of a host vehicle so that the vehicle speed of the host vehicle becomes a preset vehicle speed that is set in advance when a preceding vehicle traveling ahead of the host vehicle is not detected and for controlling the vehicle speed of the host vehicle so that the host vehicle follows the preceding vehicle when the preceding vehicle is detected. The vehicle speed control device determines whether the host vehicle is positioned in an acceleration-control-inhibited area based on the position detected by a position detection unit and, when the preceding vehicle is not detected and a position determination unit determines that the host vehicle is positioned in the acceleration-control-inhibited area, the vehicle speed control device performs acceleration-control-inhibition vehicle speed control of the host vehicle.

This vehicle control device is provided with a distribution calculation unit and a vehicle behavior prediction unit. The distribution calculation unit determines, on the basis of driving condition information that has been collected, probability distributions for when deceleration behavior occurs and does not occur. The vehicle behavior prediction unit determines the relative positional relationships between the driving speed and acceleration of vehicles ahead with respect to the probability distributions, and, on the basis of the relative positional relationships that have been determined, predicts the behavior of a vehicle that is subject to prediction.
