Vehicle course estimation device

摘要

A vehicle course estimation device which includes: a direction indicator sensor which detects an operating state of a direction indicator of a vehicle; a distance detection section which detects a distance between the vehicle and an intersection located at a travel direction side of the vehicle; a reference speed calculation section which calculates a reference speed, which is a speed for the vehicle to arrive at the intersection after a predetermined time, on the basis of the distance between the vehicle and the intersection located at the travel direction side of the vehicle, which has been detected by the distance detection section, when an operation of the direction indicator is detected by the direction indicator sensor; and a course estimation section which estimates a course of the vehicle on the basis of a speed of the vehicle with respect to the reference speed calculated by the reference speed calculation section.

1. A vehicle course estimation device comprising:
direction indicator detection means for detecting an operating state of a direction indicator of a vehicle; distance detection means for detecting a distance between the vehicle and an intersection located at a travel direction side of the vehicle; reference speed calculation means for calculating a reference speed, which is a speed for the vehicle to arrive at the intersection after a predetermined time, on the basis of the distance between the vehicle and the intersection located at the travel direction side of the vehicle, which has been detected by the distance detection means, when an operation of the direction indicator is detected by the direction indicator detection means; course estimation means for estimating a course of the vehicle on the basis of a speed of the vehicle with respect to the reference speed calculated by the reference speed calculation means; and vehicle control means for automatically controlling a travel of the vehicle based upon the estimated course of the vehicle, wherein when the operation of the direction indicator is detected by the direction indicator detection means, the reference speed calculation means calculates the reference speed on the basis of the distance between the vehicle and the intersection located at the travel direction side of the vehicle, which has been detected by the distance detection means, and a fixed time set in advance as the predetermined time.
