Driving assistance apparatus and driving assistance method
First Claim
1. A driving assistance apparatus comprising:
- a first detecting unit configured to monitor the front area of the vehicle, the left and right front areas of the vehicle, and both lateral areas of the vehicle in order to thereby detect an object by using one or more cameras and one or more radars;
an estimating unit configured to track one or more objects that are detected in at least one of the front area, the left and right front areas, or both of the lateral areas in order to thereby estimate a movement of each of the tracked objects;
a selecting unit configured to select a target object from the one or more objects based on conditions for estimating the movement of each of the tracked objects; and
a determining unit configured tocalculate the time to collision (TTC) with the target object, anddetermine whether or not a risk of collision with a rear object is occurred based on the conditions and the calculated time to collision such that the vehicle is controlled considering the rear object, wherein the risk of collision is determined to be one of three separated levels based on the calculated time to collision;
wherein the driving assistance apparatus controls either or both of a braking device and a steering device of the vehicle based on the determination that the risk of collision with a rear object is occurred by further comprising;
a first controller configured to partially control the braking device of the vehicle when the risk of collision with the target object corresponds to Level 2;
a second detecting unit configured to monitor the rear of the vehicle in order to thereby detect the rear object when the risk of collision with the target object corresponds to Level 3, which is higher in risk than Level 2; and
a second controller configured to control the braking device or the steering device based on whether or not the rear object is detected.

Abstract
A driving assistance apparatus including: a first detecting unit that monitors around areas of the vehicle to detect an object; an estimating unit that tracks objects detected in at least one area among the around areas, to estimate the movement of the object; a selecting unit that selects a target object from the objects based on the estimated movement condition; a determining unit that calculates the time to collision (TTC) with the target object, and determines a level of collision risk based on the TTC; a first controller that controls a braking device if the risk corresponds to Level 2; a second detecting unit that monitors the rear of the vehicle to detect a rear object if the risk corresponds to Level 3; and a second controller that controls the braking device or a steering device based on the rear object detection.

16. A driving assistance method comprising:
-
a first detecting operation of monitoring the front area of the vehicle, the left and right front areas of the vehicle, and both lateral areas of the vehicle in order to thereby detect an object by using one or more cameras and one or more radars; an estimating operation of tracking one or more objects that are detected in at least one of the front area, the left and right front areas, or both of the lateral areas in order to thereby estimate a movement of each of the tracked objects; a selecting operation of selecting a target object from the one or more objects based on conditions for estimating the movement of each of the tracked objects; and a determining operation of calculating the time to collision (TTC) with the target object and determining whether or not a risk of collision with a rear object is occurred based on the conditions and the calculated time to collision such that the vehicle is controlled considering the rear object, wherein the risk of collision is determined to be one of three separated levels based on the time to collision; wherein the driving assistance method controls either or both of a braking device and a steering device of the vehicle based on the determination that the risk of collision with a rear object is occurred by further comprising; a first control operation of partially controlling the braking device of the vehicle when the risk of collision with the target object corresponds to Level 2; a second detecting operation of monitoring the rear area of the vehicle in order to thereby detect the rear object when the risk of collision with the target object corresponds to Level 3 in which the risk of collision with the target object is higher in risk than that of Level 2; and a second control operation of controlling the braking device or the steering device based on whether or not the rear object is detected. - View Dependent Claims (17, 18, 19)
