Development and validation of an advanced motorcycle riding simulator

This paper illustrates and discusses the main features of the motorcycle riding simulator designed and built at the University of Padua over recent years. The simulator has been developed for a variety of purposes: to develop and test electronic devices aimed at improving rider safety and vehicle performance (antilock braking systems, traction control systems, etc.), to investigate different design choices and parameter effects on vehicle dynamics, to train riders, and to study their behaviours in different scenarios (normal riding, dangerous situations, etc.). Within the simulator the rider sits on a motorcycle mock-up provided with all the inputs available on a real motorcycle (throttle, clutch, brakes, etc.). These controls are used as inputs for an advanced virtual motorcycle model which computes the real-time vehicle dynamics. With the aim of giving the rider a proper motion cue, a washout filter converts the motion of the virtual motorcycle into the proper motion of a five-degrees-of-freedom motorcycle mock-up. Finally the audiovisual cues are delivered with a 180° panel and 5.1 surround sound system. To validate the simulator, a specific protocol which includes both an objective evaluation and a subjective evaluation was designed and carried out. External devices such as advanced rider assistant systems, on-bike information systems, and human–machine interfaces can be easily integrated into the simulator by means of a standard controller area network.
