System and method for performing autonomous emergency braking

Abstract

A system and method for performing autonomous emergency braking (AEB) is disclosed. The AEB system includes a front lateral detection sensor, a vehicle dynamics sensor, and an electronic control unit(ECU). The front lateral detection sensor detects a distance and a relative speed between a host vehicle and a peripheral object, or transmits peripheral images of the host vehicle to the ECU. The vehicle dynamics sensor detects a driving speed of the host vehicle, and transmits the detected driving speed to the ECU. The ECU receives detection signals from the front lateral detection sensor and the vehicle dynamics sensor, and increases a size of an AEB control available region and an AEB control available speed when at least one leading moving object or at least one external object is presentin longitudinal and latitudinal directions of a forward region of the host vehicle and the host vehicle is unable to perform steering avoidance capable of preventing collision with the leading movingobject or the external object. Accordingly, even when several leading vehicles are present not only in longitudinal and latitudinal directions of a forward region of the host vehicle and the host vehicle is unable to perform steering avoidance, the possibility of collision between the host vehicle and the leading vehicles can be reduced.

Description

technical field [0001] The present invention relates to the automatic emergency braking system and method based on the judgment of the surrounding conditions, and more specifically, to the following automatic emergency braking system and method based on the judgment of the surrounding conditions: judging whether steering avoidance is possible according to the surrounding conditions, thereby By adjusting the area and speed where AEB control can be performed, usability can be expanded. Background technique [0002] In general, the automatic emergency braking (AEB, Autonomous Emergency Braking) system of the vehicle is used as a vehicle to detect a leading (leading, leading) moving body (including a movable device such as a car) in front of the vehicle while the vehicle is running. When dangerous obstacles such as pedestrians, moving people, sidewalks, guardrails, curbstones, etc. are located around the road such as static facilities) and other dangerous obstacles, according to...

Problems solved by technology

For this, if image 3 As shown, there are also multiple preceding vehicles in the longitudinal and lateral directions in front of the vehicle, so, as Figure 4 In the case where steering avoidance cannot be performed as shown, there is a restriction that it is difficult to achieve collision avoidance
