Driving Support Devices for Vehicles

Abstract

PROBLEM TO BE SOLVED: To stably perform automatic braking control by which a collision with a front side control object is avoided with as much stable precision as possible and good response even if occurrence of a large pitching motion to a vehicle results in the situation that the sight of the control target is lost or front information should significantly be corrected. SOLUTION: When a pitching angle θp is larger than a threshold θpc to be preset, the possibility of a collision of the control subject with a self-vehicle 1 is determined on the basis of the running information of the control target detected at least previously. When it is determined that there is the possibility of a collision of the control subject with the self-vehicle 1, braking control by the intervention of the automatic brake is performed.

Description

technical field [0001] The present invention relates to driving of a vehicle that prevents collisions by performing braking control that intervenes in automatic braking that is separated from the driver's braking operation when there is a high possibility of a collision between the own vehicle and a control object such as a vehicle in front support device. Background technique [0002] In recent years, when the host vehicle (host vehicle) is likely to collide with the control object such as the vehicle in front, various methods of preventing the collision by performing automatic braking control separated from the driver's braking operation have been proposed. The automatic brake control device, and to be applied in the industry. For example, Japanese Patent Application Laid-Open No. 2009-262701 (hereinafter referred to as Patent Document 1) discloses a technology of an automatic braking control device that intervenes in automatic braking. The control object in front of the...

Problems solved by technology

[0004] However, when the camera cannot capture the front image due to the large pitching motion of the vehicle, even with the technology of using the pitch angle to compensate as disclosed in the above-mentioned patent document 2, it is impossible to obtain the relative position of the control object. distance, so there is a hidden danger of not being able to perform automatic braking control

In addition, even if the front image can be captured with a camera, it takes time for calculation and processing for compensation, so there is a possibility that a very accurate value cannot be obtained.
