Drive control device for vehicle and drive control method

Abstract

This drive control device (10) controls the drive of the present vehicle on the basis of a predicted course which is a prediction value of a drive course of the present vehicle. The drive control device (10) compares the movement trajectory of a preceding vehicle and the position of a stationary object provided along the road, and determines whether or not the movement trajectory is along the shape of the road. The movement trajectory is found valid if it is determined that the movement trajectory is along the shape of the road, and the movement trajectory is found invalid if it is determined that the movement trajectory is not along the shape of the road. The predicted course of the present vehicle is calculated on the basis of the valid movement trajectory.

Description

technical field [0001] The present disclosure relates to travel control of a vehicle, and in particular, to a travel control technique for controlling travel of a host vehicle based on a predicted route of the host vehicle. Background technique [0002] As one of vehicle driving assistance controls, following control is known in which a vehicle in front traveling in the same lane as the vehicle performs follow-up control in which a vehicle in front follows the vehicle in front of the vehicle. In such follow-up control, it is important to accurately specify, for example, a vehicle traveling in the same lane as the own vehicle from among vehicles ahead detected by a sensor, a camera, or the like. Therefore, conventionally, the future traveling route of the host vehicle is obtained by calculation, and the vehicle ahead that exists on the future traveling route is set as the object of the follow-up control. In addition, various methods of calculating the future travel route of ...

AI Technical Summary

Problems solved by technology

[0004] In the above-mentioned Patent Document 1, it is not assumed that the vehicle ahead unexpectedly changes lanes and leaves the lane. When such a situation occurs, the calculation accuracy of the route prediction of the own vehicle may decrease.

In addition, since the movement trajectory of the vehicle in front can only be obtained in the inter-vehicle section from the own vehicle to the vehicle in front, there is concern that the prediction of the future travel route will be limited.
