Demonstrators

There are three riding simulators and eight PTW of all different kinds available to install different ARAS, OBIS and HMI systems. Different ARAS, OBIS and HMI systems will be installed on the bikes and simulators in order to test and demonstrate their function in different kinds of motorcycles and in different scenarios. Moreover the potential of a full integration between ARAS and OBIS will be demonstrated on one large motorcycle which will be able to carry all the components of the ARAS / OBIS and HMI.

Simulators tests will be made using the UNI PADOVA (Padova, Italy), INRETS (Paris, France) and CERTH (Thessaloniki, Greece) riding simulators.

Riding Simulator in Padova

UNIPD posses a top of the range motorcycle riding simulator designed and developed at DIMEG (Dept. of Innovation in Mechanics and Management). On the simulator the rider sits on a motorcycle mock-up and operates on the throttle position, brakes, the clutch and gearshift lever like in a real bike, moreover the handlebar and footpads are sensorized and the rider control actions are transferred to the software which simulates the motorcycle dynamics. The simulate motorcycle motion is finally used to simulate the riding experience by generating a proper motion and audiovisual cues.

The motion cues is achieved by means of five active degrees-of-freedom: lateral displacement (±0.3 m at ±2 m/s), roll and yaw rotations (±0.3 rad at ±2 rad/s), pitch and steer rotation (±0.12 rad at ±0.2 rad/s). As it is well know that it is physically impossible to reproduce accelerations like in real riding, a wash-out filter is used to convert the motion of the virtual bike into the motion of the constrained mock-up. The position of yaw, roll and pitch axis have been accurately selected for a better riding experience. Moreover, this specific mechanical architecture allows to dynamically change the position of yaw and roll axis during virtual riding. the visual systems consists in a projection system that project the scenario on three widescreens of size 1.5x2 m2 placed in front of the rider with a 180° horizontal field. A 5.1 surround system provides the generation of the environment sounds all around the rider, e.g. by reproducing the sound of a real engine according to the engine spin rate.

On the simulator the rider interacts in a virtual scenario with several multimedia contents: vocal messages, text, graphics (rendered through the 3D engine used for the visual system) and sound generation. Moreover the core engine has custom functions and objects so that it is possible to allow traffic management, scene environment management, vehicle control and feedback, multimedia component control, etc. From the practical point of view, this means that it is possible to ride the simulator among other vehicles (motorcycles, cars, trucks), traffic lights and pedestrian which behave according to the programmer rule. In particular it is possible to simulate dangerous situations. This virtual environment is based on the ECA-FAROS technology. The modular architecture of the simulator software makes the connection to different scenarios based on different technologies possible. The UNIPD riding simulator is able to reproduce the most important vehicle dynamics: motorcycle counter-steering, capsize, weave and wobble instabilities, wheeling, skidding, etc.

Within SAFERIDER project, the UNIPD simulator has been employed for the technical development in a safe and reliable environment for ARAS functions such as the Curve Warning (CW), Frontal Collision Warning (FCW) and Intersection Support (IS). Curve Warning (CW) and Intersection Support (IS) function have been also tested with final users, by using three different HMI systems: the navigation and route guidance display, the haptic (vibrating) glove, and the haptic throttle. Each HMI selection has been tested in two different configurations, one designed for rider acceptance and the other designed for high effectiveness of the warnings.

The INRETS motorcycle simulator is based on a real motorcycle frame with fully functional commodos, throttle, brakes and gear shifting devices. This motorcycle frame is mounted on a motion base. The motion base has actuators allowing movements in roll, pitch (tilt) and yaw (all ± 15°). An additional actuator allows linear movement of the handlebars towards or away from the rider over a range of approximately ± 15cm. This allows to cue some of the effects of accelerating or braking: pull on the grips in the former case, push on the grips in the latter. Finally, force-feedback can be applied on the handlebars via a motor operating directly on the steering column.

Motion cues of the INRETS motorcycle simulator

The INRETS motorcycle simulator uses the INRETS SIM² simulator architecture. This architecture is based on the use of the ARCHISIM multi-actors traffic simulation model. Using this architecture, driving simulators can participate to a traffic simulation. Each simulator which participates to the simulation is considered as one of the actor of the simulated traffic situation. A simulator can be as complex as needed by the application. The human can move in the virtual world using either a joystick, a game steering wheel, a simplified motorcycle mock-up or a full motorcycle. One can use a dynamic motion base. The visual rendering is achieved using either screen or monitors. The rendered field of view can be up to 360°.

Two ARAS will be tested on the INRETS’ simulator : the Lane Change Support (LCS) and the Frontal Collision Warning (FCW).

The LCS tests will be carried out with four HMI systems: the navigation and route guidance display (VD), the mirror with visual attractor (VAM), the accoustic signal tone (AA) and the smart helmet (THL).

The FCW tests will be carried out with three HMI systems: the navigation and route guidance display (VD), the accoustic signal tone (AA) and the smart helmet (THL).
