Abstract

A drive assist system for a vehicle includes: a driving environment recognizer that recognizes driving environment information including a lane marking line and vehicles; a front vehicle extractor that extracts a front vehicle based on the driving environment information; A first driving state classifier that classifies a driving state of the vehicle as one of a first steady driving state, a first lane changing state, and a first target lane driving state, based on lateral movement information of the vehicle and relative position information of the vehicle to the lane marking line; and a second driving state classifier classifies a driving state of the front vehicle as one of a second steady driving state, a second lane changing state, and a second target lane driving state, based on lateral movement information of the front vehicle and relative position information of the front vehicle to the lane marking line.

Claims3

Dependent claims

A drive assist system configured to be applied to a vehicle, the drive assist system comprising:

a driving environment recognizer configured to recognize information on a driving environment including a lane marking line and one or more vehicles driving on a road, the lane marking line being a line defining a lane on the road;
a front vehicle extractor configured to extract, as a front vehicle, one of the one or more vehicles that is driving in front of the vehicle to which the drive assist system is configured to be applied, based on the information on the driving environment;
a first driving state classifier configured to classify a driving state of the vehicle to which the drive assist system is configured to be applied as one of a first steady driving state, a first lane changing state, and a first target lane driving state, based on information on a movement of the vehicle in a lateral direction and information on a relative position of the vehicle to the lane marking line, the first steady driving state being a state in which the vehicle is steadily driving in the lane, the first lane changing state being a state in which the vehicle is changing the lane in the first steady driving state to a target lane adjacent to the lane, the first target lane driving state being a state in which the vehicle is driving in the target lane;
and
a second driving state classifier configured to classify a driving state of the front vehicle as one of a second steady driving state, a second lane changing state, and a second target lane driving state, based on information on a movement of the front vehicle in the lateral direction and information on a relative position of the front vehicle to the lane marking line, the second steady driving state being a state in which the front vehicle is steadily driving in the lane, the second lane changing state being a state in which the front vehicle is changing the lane in the second steady driving state to the target lane adjacent to the lane, the second target lane driving state being a state in which the front vehicle is driving in the target lane.

A drive assist system configured to be applied to a vehicle, the drive assist system comprising:

a driving environment recognition unit comprising a sensor configured to recognize information on a driving environment including a lane marking line and one or more vehicles driving on a road, the lane marking line being a line defining a lane on the road;
and
a processor configured to
extract, as a front vehicle, one of the one or more vehicles that is driving in front of the vehicle to which the drive assist system is configured to be applied, based on the information on the driving environment,
classify a driving state of the vehicle to which the drive assist system is configured to be applied as one of a first steady driving state, a first lane changing state, and a first target lane driving state, based on information on a movement of the vehicle in a lateral direction and information on a relative position of the vehicle to the lane marking line, the first steady driving state being a state in which the vehicle is steadily driving in the lane, the first lane changing state being a state in which the vehicle is changing the lane in the first steady driving state to a target lane adjacent to the lane, the first target lane driving state being a state in which the vehicle is driving in the target lane, and
classify a driving state of the front vehicle as one of a second steady driving state, a second lane changing state, and a second target lane driving state, based on information on a movement of the front vehicle in the lateral direction and information on a relative position of the front vehicle to the lane marking line, the second steady driving state being a state in which the front vehicle is steadily driving in the lane, the second lane changing state being a state in which the front vehicle is changing the lane in the second steady driving state to the target lane adjacent to the lane, the second target lane driving state being a state in which the front vehicle is driving in the target lane.
