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.

Driving assistance system for vehicle

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 S. 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 S

Vehicle driving assistance system

After determination of from which side, right or left, a second vehicle is approaching, a position of a collision point is determined, a position of a stop point is set from the determined collision point, and a warning is given at a position and timing of a warning point which is set to allow a first vehicle to stop before the set stop point.
