Method and apparatus for assisting forward collision avoidance based on driving environment

An apparatus for forward collision avoiding assist, the apparatus comprising:

• a driving environment information collector configured to collect driving environment information of a vehicle by using at least one of GPS or V2X communication;
• a front object information acquirer configured to detect at least one front object positioned in front of the vehicle and acquire front object information of the at least one front object using at least one of a camera or a radar;
• a driving trajectory generator configured to generate a driving trajectory of the vehicle based on motion information on the vehicle, the motion information obtained from at least one sensor mounted on the vehicle;
• a candidate object selector configured to select a candidate object from the at least one front object based on the driving environment information and the front object information;
• a target object determiner configured to determine a target object based on information of the candidate object and the driving trajectory of the vehicle;
• and
• a controller configured to control a brake system included in the vehicle based on a risk of collision between the vehicle and the target object,
• wherein the driving environment information comprises a type of road on which the vehicle is traveling,
• wherein the candidate object selector is further configured to acquire an expected object type suitable for the type of road on which the vehicle is traveling from a reference table, the reference table includes information on at least one expected object type corresponding to each road type among a plurality of road types road, and to select, from the reference table, an object corresponding to the expected object type as the candidate object,
• wherein the candidate object selector is further configured to identify a front object that is not selected as the candidate object, as a possibly misrecognized object, to cross-check again whether the at least one sensor has misrecognized the possibly misrecognized object, and to determine whether to select the possibly misrecognized object as the candidate object according to a result of the cross-checking, and
• wherein the target object determiner is further configured to classify a plurality of candidate objects by each object type, and to determine multiple target objects by each object type by determining each candidate object for each object type positioned in the driving trajectory of the vehicle.

A non-transitory computer-readable recording medium having instructions stored therein, wherein the instructions, when executed by a computer, cause the computer to execute the following operations:

• collecting driving environment information of a vehicle;
• detecting at least one front object positioned in front of the vehicle and acquiring front object information of the at least one front object;
• generating a driving trajectory of the vehicle based on motion information of the vehicle;
• selecting a candidate object from the at least one front object based on the driving environment information and the front object information;
• determining a target object based on information of the candidate object and the driving trajectory of the vehicle;
• and
• controlling a brake system included in the vehicle based on a risk of collision between the vehicle and the target object,
• wherein the driving environment information comprises a type of road on which the vehicle is traveling,
• wherein the selecting comprises:
• acquiring an expected object type suitable for the type of road on which the vehicle is traveling from a reference table, the reference table includes information on at least one expected object type corresponding to each road type among a plurality of road types;
• selecting, from the reference table, an object corresponding to the expected object type as the candidate object;
• and
• identifying a front object that is not selected as the candidate object, as a possibly misrecognized object,
• cross-checking again whether a sensor has misrecognized the possibly misrecognized object;
• and
• determining whether to select the possibly misrecognized object as the candidate object according to a result of the cross-checking, and
• wherein the determining a target object comprises:
• classifying a plurality of candidate objects by each object type;
• and
• determining multiple target objects by each object type by determining each candidate object for each object type positioned in the driving trajectory of the vehicle.
