Lane keeping under cognitive distractions: performance and mechanisms
… while driving often reduce the variability of lane position. However, data do not make clear whether smaller lane variability should be interpreted as a performance loss, indicating rigidified or unresponsive steering response to external stimuli, or a performance improvement in lane-keeping, …

Modeling and Simulation of Lane Keeping Support System Using Hybrid Petri Nets
… thesis is to develop, analyze and simulate a lane keeping support system using an HPN model. Chapter 1 includes a brief summary of the specific ADAS used, lane departure warning and lane keeping assist systems and then related work on PNs is mentioned. Chapter 2 provides a background on Petri …

Safety of Self-driving Cars: A Case Study on Lane Keeping Systems
… specifications during the whole delay. We use a lane keeping system as a small but representative case study to evaluate our approach. We utilize an end-to-end neural network as a typical implementation of such a lane keeping system. Our shield supervises those outputs of the neural network and …

Integrating Collision Avoidance, Lane Keeping, and Cruise Control With an Optimal Controller and Fuzzy Controller
… presents collision avoidance integrated with lane keeping and adaptive cruise control for a car. Collision avoidance is the ability to avoid obstacles that are in the vehicle's path, without causing damage to the obstacle or car. There are three types of collision avoidance controllers, …

Development of a strategy model of the driver
… postulated for describing driver behavior in the lane-keeping task, To verify the appropriateness of this class of models, 10 student subjects were chosen to be modeled. Each subject performed the lane-keeping task in a highway driving simulator for five minutes. Each subject's time histories of …

Fleetwide Models of Lane Departure Warning and Prevention Systems in the United States
… In response, automakers have been developing lane departure active safety systems to alert drivers to impending departures. These lane departure warning (LDW) and lane departure prevention (LDP) systems have great potential to reduce the frequency and mitigate the severity of serious lane and …

Haptic Interface for Non-Visual Steering
… small curves and that it can improve a driver's lane keeping ability when combined with visual feedback. We improved our interface to identify whether this allows for blind steering with no visual feedback by users who are blind. We conducted a user study with an adapted version of our interface …

Lane departure avoidance system
… to reduce the number of accidents. Focusing on lane departure, a leading cause of crashes involving fatalities, we examine a lane-keeping system proposed by Minoiu Enache et al.They proposed a switched linear feedback (LMI) controller and provided two switching laws, which limit driver torque …

Aging and the Effects of Conversation With a Passenger of a Caller on Simulated Driving Performance
… a driving simulator. The results showed better lane keeping and more stable velocity control when drivers conversed with their partner compared to driving only. Drivers also showed faster average velocity under single-task than under dual-task conditions. Older drivers showed evidence of …

A unified framework for trajectory planning, threat assessment, and semi-autonomous control of passenger vehicles
… driver. Various maneuvers are tested, including lane-keeping, hazard avoidance, and multiple hazard avoidance and show that this framework capable of maintaining vehicle stability while semi-autonomously avoiding road hazards and conceding significant control to the human driver.

Comparison of a computer generated display and a simulated motion picture display in driving simulation
… subject. The first four minutes consisted of a lane keeping task under combinations of simulated straight road, curved road, and lateral and longitudinal wind gust conditions. In the fifth and sixth minute, subjects were instructed to perform lane change maneuvers. However, in the fifth minute, …

Investigating and Characterising the Impact of Vehicle Interfaces on Situation Awareness
… Supporting the DRA, while successful for Lane-keeping, did not operate as intended. Drivers were not able to adequately use concurrent feedback due to not achieving a skilled level of behaviour. Finally, increased awareness impacted how a driver manages their attention. Drivers acted more …

Methodology development and evaluation of automotive LiDAR performance in rain
… (ADAS) offered in modern vehicles. Features like lane-keeping assistance, adaptive cruise control, and emergency braking rely on sensors to capture environmental data. However, sensor performance degrades in adverse weather conditions. For instance, light detection and ranging (LiDAR) sensors are …

The Distracted Driver: Modeling the Impact of Information Bandwidth, in -Vehicle Task Priority, and Spatial -Separation on Driver Performance and Attention Allocation
… the relative contribution of ambient vision to lane keeping performance with two different IVT displays locations (i.e., scans to the road were prohibited). We also examined the impact of increasing wind turbulence (bandwidth) on visual scanning behavior. Experiment 2a revisited the impact of …

The Effects of System Transparency and Reliability on Drivers' Perception and Performance Towards Intelligent Agents in Level 3 Automated Vehicles
… transparency influenced drivers' takeover time, lane keeping, and jerk. The high-reliability agent was associated with the higher perception of system accuracy and response speed, and longer takeover time than the low-reliability agent. Participants in T2 transparency showed higher cognitive …

Advanced Driver Assistance Systems and Older Drivers – Mobility, Perception, and Safety
… of ADAS presence on older drivers' safety. When lane keeping assist (LKA) was engaged, lower high longitudinal deceleration was observed than when LKA was not engaged, indicating that older drivers tended to apply less aggressive braking when using LKA. Over several weeks of exposure to vehicles …
