Objective: The objective of this study is to investigate the intrusive feeling caused by a Lane Keeping Assistance System (LKAS) and measure it objectively through the sensor log data of a vehicle.
Background: LKAS, one of the Advanced Driver Assistance System (ADAS), directly intervenes in the steering wheel control to assist the driver to keep the lane. Due to the torque generated by the LKAS, the driver has a different and undesirable feeling from a usual situation, which can affect the driving experience. Nevertheless, the performance of the LKAS in most studies focused only on how well the system keeps the lane.
Method: Through an actual driving test using a test vehicle equipped with an LKAS, two ADAS experts and two human factor experts observed the intrusive feeling while collecting sensor log data at the same time. After the types of the intrusive feeling were classified, variables that could account for the feeling were derived. Then, this study compared the data collected from the vehicle with and without the intrusive feeling.
Results: Three types of the intrusive feeling were observed: abrupt lateral change, steering wheel vibration, and heavy steering. The lateral speed (LS), the high-pass filtered steering angle (FSA), and the interrupt torque (IT) were then derived as the variables that could explain each feeling, respectively. It is found that the patterns of the derived variables are different in driving with and without the intrusive feeling.
Conclusion and Application: The intrusive feeling found in this study can be used as a performance index in the development stage of the LKAS. It will be helpful to systematically reduce the intrusive feeling.
