APPARATUS AND METHOD FOR ASSISTING LANE CHANGE

摘要

PURPOSE: A lane change auxiliary device and a method are provided to improve not only an alarm for a dangerous situation when a driver changes a lane but also the safety and convenience of the driver with a steering torque and accelerating force auxiliary. CONSTITUTION: A lane change auxiliary device comprises a distant sensor(10) sensing the distance from a vehicle of a front rear side direction; an alarming unit(12) which generates a warning sound; an auxiliary engine torque generating unit(14) which generates an engine torque assisting the deceleration or the acceleration of a vehicle speed; and a control unit(18) receiving a turn signal and maintaining a headway gap if a vehicle access from a rear side direction by a signal from the distant sensor and operating the alarming unit, receiving the turn signal and decelerating while changing the lane by driving the auxiliary engine torque generating unit if the vehicle exists in a front side direction by the signal from the distant sensor.
