Vehicle driving supporting device

Abstract

The invention discloses a vehicle driving supporting device which can make an excellent action with the stable precision and executes the automatic braking control stably when the vehicle loses a control object in a big pitching movement, and needs big compensation to the front information so as to avoid the collision with the front control object. According to the invention, when the pitching angle theta p is bigger than a preset threshold theta pc, the vehicle driving supporting device can judge the collision possibility between the control object and the vehicle (1) at least according to the control object driving information which is previously detected. When the judgment indicates that the control object has the collision possibility with the vehicle (1), the automatic braking control takes effect.

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 there is a high possibility of a collision between a host vehicle and a control object such as a vehicle in front, various methods have been proposed to prevent the collision by performing automatic braking control separated from the driver's brake operation. Such 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...

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.
