evasive steering maneuver definition

In (b) 17 drivers attempted to achieve maximum velocity, around a wet skid-pad while trying to retain control of the Astra. We describe initial steps in the design of a haptic shared control system for obstacle avoidance in unmanned aerial vehicle (UAV) teleoperation.

Chapter 7); the work that will be presented in this thesis revealed that steering support near the vehicle’s handling limits can reduce the drivers’ mental and physical demand and can potentially promote safety. [online] Available: http://www.nissan-global.com/EN/ Those computers and electronic devices may employ various volatile and/or non-volatile memories including non-transitory computer-readable medium with an executable program stored thereon including various code or executable instructions able to be performed by the computer or processor, where the memory and/or computer-readable medium may include all forms and types of memory and other computer-readable media.

Many such systems generate torques using a simplified and constant lane-keeping model based on a look-ahead controller, without accounting for individual differences. Chapter 7 is divided into two parts (A, B). However, for large inertia vehicles such as trucks, such strategies which involve engine/transmission or brake control, may likely prove inadequate for avoiding collisions with vehicles on either side or with animals. in an area where a driving stability control, such as a yaw moment control, for example according to, By controlling the rear axle steering of the motor vehicle. If the system detects a MyKey, the system will automatically turn on and default to alert mode. Also, we propose the kinesthetic feedback on the game framework and implement a realistic game in serious game using this proposed framework. Exploring the above statement, the goal of this study is to develop and evaluate a haptic steering support when driving near the vehicle’s handling limits (Haptic Support Near the Limits; HSNL). The foregoing discussion disclosed and describes merely exemplary embodiments of the present invention.

The driving simulator and the real vehicle tests led to the conclusion that haptic support assisted the test subjects to drive closer to the designated path while achieving effectively the same speed. In the interface design of the proposed collision avoidance system proposed in this article, the human-machine issues complicating task automation were avoided by adopting a human-centered approach. The analysis accounted for the driving performance and effort along with the subjective ratings of comfort, safety, control and workload. This paper proposes a haptic assistance system that provides momentary steering wheel torque to help the driver choose the steering direction for avoiding collision with a pedestrian.

Chapter 5 has been divided into three parts (A, B, C), all related to real vehicle testing. The drivers were instructed to achieve maximum velocity through corners while receiving haptic steering feedback cues related to the vehicle's cornering potentials. During normal car-following situations, the haptic feedback (HF) cues were sufficient to reduce control activity and improve car-following performance. © 2008-2020 ResearchGate GmbH. ... Another promising solution for object avoidance is to use continuous force feedback on the steering wheel, an approach that may work both when the driver touches and when the driver releases the steering wheel. A haptic gas pedal feedback system is developed that provides car-following information via haptic cues from the gas pedal.

The concepts of adaptive automation and human machine cooperation suggest that the authority of the automation should be adapted in real time according to the situation.

Developing a feel for symbiotic driving - Establishing haptic shared control as adaptive, individualized interaction between driver and highly-automated car

It is a feedback process to get solutions of the parameters for a given vehicle load.

In order to investigate the effectiveness of the system, we conducted an experiment with a medium fidelity driving simulator.

However, the haptic guidance system resulted in a relatively large increase in steering forces, which could also be a disadvantage for elderly drivers. Finally, to facilitate design choices for other applications, we propose a hierarchical framework for shared control that links the shared control literature with traded control, co-operative control, and other human–automation interaction methods. A four wheel vehicle model with nonlinear tire characteristics is introduced and the steady-state drifting conditions are solved numerically to derive the corresponding control inputs.

This milestone-oriented approach can be divided into seven steps: i) Study the state-of-the-art driver support systems and identify the potential space for improvement. The human may express his control intentions in a way that either overrides the automation or conforms to it. This system can serve as an intuitive 'manual override' function in case of HSC system malfunction. Six TORs were provided per session, warning the participants about a stationary vehicle that had to be avoided by changing lane left or right. In conclusion, shared control for RDP is effective, although more research needs to be conducted regarding the human response in situations where the relationship between the steering wheel angle and the front wheels' steering angle is altered while driving.

Two cases are studied: 1) the JND in perceiving the stiffness of manipulators with various masses; 2) the JND in perceiving the damping of a combined mass-spring-damper system with varying stiffness and mass.

and the boundary conditions are defined as: 19.

Content within this document reflects the latest research and original equipment manufacturer (OEM) activity as of June 2013. The effect of false alarms on human trust in warning systems and on credibility of warnings could be considerable even for low false alarm rates.

Nuclear accident recovery, deep water operations, and remote satellite servicing are just three examples.

We hypothesized that the absence of essential visual information from the environment critical to lateral control of the vehicle - either near or far visual information - could adequately be compensated for by haptic guidance on the steering wheel. all-wheel steering characterised by means varying the ratio between the steering angles of the steered wheels, Steering linkage; Stub axles or their mountings for individually-pivoted wheels, e.g. In previous research we did on haptic shared control, we used a simple 2-parameter lane keeping controller to generate guidance torques [4], [5]. N.D. Lerner, D.K. In this paper, we proposed a game framework that applied the haptic device to the game for efficient conveyance of the tactile sensation and it is based on the input and output in the 3D. If the vehicle 62 is in autonomous driving, then the algorithm provides lane centering and path generation as described above at box 126, and if the vehicle 62 is being manually driven, then the algorithm calculates the predicted vehicle path 94 as discussed above at box 128. A sequence of driving tasks has been carried out in a driving simulator.

With shared control, the driver receives continuous force feedback on the gas pedal or steering wheel, so that human and machine conduct the driving task simultaneously. Haptic shared control systems aim to guide drivers during steering using guidance torques. Il est donc nécessaire d’intégrer dès la conception du système automatisé de conduite, la problématique des interactions avec le conducteur en réglant les problèmes de partage de tâche et de degré de liberté, d’autorité et de niveau d’automatisation du système. ... with everyone competing with one another to maneuver for better spots to see the race.

The invention relates to a method for performing an evasive maneuver in front of a surrounding object with which the vehicle is on a collision course.

DOT HS 808 533. This report introduces an optimal preview control algorithm which utilizes preview information pertaining to road curvature as well as superelevation angle for vehicle lateral control purposes.

The results of an experiment with a medium fidelity driving simulator show that the proposed system is effective to reduce the number of crashes that the original one can not prevent. We also conceptually describe how the proposed controller can motivate a driver steering support drifting interface in the by-wire sense. The haptic shared control had a significant influence on the measured steering torque, but limited effect on the steering wheel angle and the vehicle path.

DBW prevented road departure and reduced mental workload, but lead to inadvertent human-initiated counter-steering.

On the basis of weighting the frequency response magnitude of mechanical properties, we performed model identification that fit the experimental observations, and extended the JND laws for the two testing cases.

As will be well understood by those skilled in the art, the several and various steps and processes discussed herein to describe the invention may be referring to operations performed by a computer, a processor or other electronic calculating device that manipulate and/or transform data using electrical phenomenon. Their steering activity was reduced and smoother. ... Mulder et al.

We present a driving-simulator experiment which evaluated various steering interfaces of a road-departure prevention (RDP) system in an emergency situation.

The system that determines the correcting steering input is a RDP controller based on the driver's inputs. The feedforward preview control action significantly improves tracking performance while maintaining a small closed loop bandwidth so ride quality is not impaired.
