Real road vehicle tests are time consuming, laborious, and costly, and involve several safety concerns. Road vehicle motion simulators (RVMS) could assist with vehicle testing, and eliminate or reduce the difficulties traditionally associated with conducting vehicle tests. However, such simulators must exhibit a high level of fidelity and accuracy in order to provide realistic and reliable outcomes. In this paper, we review existing RVMS and discuss each of the major RVMS subsystems related to the research and development of vehicle dynamics. The possibility of utilising motion simulators to conduct ride and handling test scenarios is also investigated.

“…Thus, we distinguished two different cases (with and without rider), we used the static method presented in section (3), each scenario being tested once without the rider then with rider. With the measurements of the vertical forces it is possible to calculate the values of the parameters a, b and h by equation (5). Table I presents experimental test carried out on the scooter of the laboratory .…”

“…The objective of our research is to study motorcycle turning, the development of active riding assistances and preventive safety systems that can warn riders upstream of hazardous driving situations to ensure acceptable levels of comfort and safety, taking into account the infrastructure and the near environment [3] [4]. In this perspective, measures aiming to reduce vulnerable riders accidents should be studied, taking into account the fact that PTWv have a specific dynamic behavior that will sometimes lead to greater control difficulties [5].…”

The paper aims to identify model's parameters of powered two-wheeled vehicles (PTWv) allowing us to simulate and interpret its lateral dynamics. The motorcycle motion is identified in order to conduct a preliminary study of simulated behavior of the vehicle while riding. An algebraic identification method for continuous-time linear system is used to obtain an accurate model of the motorcycle under the steering inputs persistent condition, vehicle dynamics tools are mainly used to simulate the different responses and to compare the identified parameters using the BikeSim software. The validation of this model is investigated using data measurement in order to confirm the accuracy of the parameters estimation.

“…Although the 6-DOF Stewart hexapod is a de facto standard, this device is not always required to achieve a good immersive experience and in many cases it may be unaffordable. In fact, recent approaches (Arioui et al, 2009;Dingxuan et al, 2001;Nehaoua et al, 2008) focus on radically different strategies based on the use of limited-DOF mechanisms that both maintain the inherent advantages of PM while providing other advantages in terms of cost reduction in manufacturing and simpler mechanical design. This reduction in cost has motivated this research work.…”

Motion generation systems are becoming increasingly important in certain Virtual Reality (VR) applications, such as vehicle simulators. This paper deals with the analysis of the Inverse Kinematics (IK) and the reachable workspace of a three-degrees-of-freedom (3-DOF) parallel manipulator, proposing different transformations and optimizations in order to simplify its use with Motion Cueing Algorithms (MCA) for self-motion generation in VR simulators. The proposed analysis and improvements are performed on a 3-DOF heave-pitch-roll manipulator with rotational motors, commonly used for low-cost motion-based commercial simulators. The analysis has been empirically validated against a real 3-DOF parallel manipulator in our labs using an optical tracking system. The described approach can be applied to any kind of 3-DOF parallel manipulator, or even to 6-DOF parallel manipulators. Moreover, the analysis includes objective measures (safe zones) on the workspace volume that can provide a simple but efficient way of comparing the kinematic capabilities of different kinds of motion platforms for this particular application. IntroductionHuman-computer interactions can be really complex in simulation systems where a believable motion generation is needed for the fulfilment of the simulation goals. The use of motion platforms to add inertial cues can significantly enhance the user immersion in the simulator, provided the system is properly tuned (Casas et al., 2016;Nahon and Reid, 1990;Reid and Nahon, 1986). The understanding of motion platforms' behavior and functioning is necessary to design effective and immersive experiences with this kind of simulators. In this regard, there are several works in the literature focused on the analysis of the behavior of several motion mechanisms with different features. However, it is hard to find research works focused on the peculiarities of the usage of motion platforms for motion generation in real-time vehicle simulation, which is the main target of this contribution.One of the most important features of motion platforms when used in vehicle simulators is the amount of linear and angular displacement the device is able to provide over the different axes. These features are crucial since they can affect the physical validity of the simulator (Reymond and Kemeny, 2000) and enhance/reduce the magnitude distortion (Sinacori, 1977) of the generated perceptual cues. In consequence, they condition the experience of the simulators' users (Casas et al., 2015). These features are generally known in the literature as the workspace. This workspace can be expressed in terms of a Cartesian space or in terms of the amount of degrees-of-freedom (DOF) the manipulator is able to reach. For motion simulation, it is much more interesting to analyze it in terms of DOF-space due to the fact that motion platforms are usually designed based on the DOF, rather than in absolute positions.The goal of these motion platforms is to provide the user with the most suitable perception of driving/piloting the...
