The purpose of lane keep assist (LKA) is: A. To warn the driver if moving out of a lane
B. Used with adaptive cruise control to self-drive the vehicle without driver input or control
C. To use the electric power steering to keep the vehicle within the lane
D. Both A and C
The correct answer is D. Both A and C.
Lane Keep Assist (LKA) primarily serves two functions: it warns the driver if they begin to move out of their lane (Option A) and actively assists by using electric power steering to help keep the vehicle centered within the lane markers (Option C). Therefore, both A and C accurately describe the purpose of LKA.
