Problems solved by technology

[0003] In the above-mentioned general driving control device, since the driving speed of the own vehicle is controlled according to the relative distance and speed of the vehicle in front, compared with an experienced driver, judging the states of a plurality of vehicles ahead to adjust the driving speed of the own vehicle. The speed of the vehicle is easily affected by the acceleration and deceleration of the vehicle directly in front, and sudden acceleration and deceleration will occur

Abstract

A travel controller (10) is provided with an intersection-stopped-vehicle-determining unit (12) and a vehicle-stop-position-prediction unit (13). The intersection-stopped-vehicle-determining unit determines, on the basis of: distance information acquired by a forward-vehicle detector (1), the distance information indicating the distance from the host vehicle to individual forward vehicles; and distance information acquired by a forward-intersection-distance-acquisition device (2), the distance information indicating the distance to an intersection ahead of the host vehicle, whether the forward vehicles are stopped vehicles that are stopped in an intersection. If it has been determined that a forward vehicle is a stopped vehicle, the vehicle-stop-position-prediction unit predicts the position at which the host vehicle will stop in the intersection on the basis of the distance information for the stopped vehicle.

Description

technical field [0001] The present invention relates to a travel control device having a function of tracking a vehicle ahead. Background technique [0002] A driving control technology called adaptive cruise is being put into practical use as follows: in a driving control device that automatically drives the vehicle at a speed set by the driver, sensors detect the distance between the vehicle and the vehicle ahead. When the distance between the vehicle and the vehicle in front is close to a certain extent, the speed of the vehicle is adjusted according to the speed of the vehicle in front. Recently, a travel control device has been put into use that not only adjusts the output of the power train but also controls the actuators, and has the function of stopping the host vehicle when the vehicle ahead slows down or stops. . [0003] In the above-mentioned general driving control device, since the driving speed of the own vehicle is controlled according to the relative dista...
