“…To reproduce urban scenarios, the AB is tested in curves with low velocities (25–40 km/h) and small lean angles (20–30°) (see Table 1 ). Nowadays there are no field experiments with AB activation in curves, although some applications in curves on real accidents have been studied via numerical simulations [14] . However, even if the potential benefits of MAEB in cornering are few and still not clear, it is nevertheless important to study the behavior of riders in the event AB activation during leaning.…”

Autonomous Emergency Braking (AEB) was proved to be an effective and reliable technology in reducing serious consequences of road vehicles crashes. However, the feasibility in terms of end-users’ acceptability for the AEB for motorcycles (MAEB) still has to be evaluated. So far, only Automatic Braking (AB) activations in straight-line motion and decelerations up to 2 m/s 2 were tested with common riders. This paper presents a procedure which provides comprehensive support for the design of new experiments to further investigate the feasibility of MAEB among end-users. Additionally, this method can be used as a reference for designing tests for other advanced rider assistance systems. A comprehensive literature review was carried out to investigate previous findings related to MAEB. After that, a series of pilot tests using an automatic braking device on an instrumented motorcycle were performed. The specifications for new AB experiments were defined (in terms of test conditions, participants requirements, safety measures, test vehicles and instrumentation). A test protocol was defined to test the system in different riding conditions and with different AB working parameters. A proposal for the data analysis was presented.

“…Although this research topic has been covered extensively, they refer exclusively to two-track vehicles. A relevant exception to this is the publication of Savino et al (2013). This article, based on an estimation method proposed by Tanelli et al (2009), addresses the road-grip potential estimation of a motorcycle during a braking manoeuvre along a straight path with a linear basis function for the tyre characteristics.…”

“…It is reasonable to assume that the excitation level in the longitudinal direction is higher than in the lateral direction for an everyday use case. Therefore the chosen driving manoeuvre is similar to that used by Savino et al (2013).…”

The tyre-road contact is the only connection of a motorcycle with the ground and has therefore a decisive influence on its longitudinal and lateral dynamics. Due to this fact, knowledge of the tyre-road friction potential can contribute to performance improvements of current motorcycle systems as Anti-Lock Braking System (ABS), Traction Control System (TCS), Stability Control System and may also be required for the development of further functions of an Advanced Driver Assistance System (ADAS). Basically, the road-grip estimation methods can be classified into cause-based and effect-based identification methods. Former are based on the identified environmental conditions such as the temperature, rain detection, and water or snow detection on the roadway to infer a change of the grip conditions. This can also be done predictively within certain limits, but usually only allows the classification of the grip conditions. The latter uses the effects of the current tyre-road contact conditions on the tyre/motorcycle dynamic behaviour to estimate the maximum friction potential. In this case, real-time capable models are required, which represent, in addition to the dynamic behaviour of the motorcycle, also the tyre forces and torques appropriately.
