This work presents a study on the braking style and its implications on motorcycle stability. First, a simplified motorcycle model is used for highlighting basic phenomena which occur during braking and for developing an ideal braking strategy. Then, braking maneuvers are analyzed using a detailed multi-body model, which takes into account all relevant characteristics of a motorcycle, such as geometry, mass and inertia distribution, non-linear suspension and tire properties. Simulations are repeated for dry and wet road conditions, showing that the correct braking style should change as the adherence conditions change, according to the suggestions given by the simplified model. Finally, stability analysis is carried out for different speeds, deceleration rates and braking styles, showing that a correct braking balance may significantly improves vehicle stability.read more

Decision logic of an active braking system for powered two wheelers
TL;DR: In this paper, the authors report on the design of the decision logic for deploying a PTW autonomous braking system in case of an imminent collision, and the feasibility of the autonomous deceleration is demonstrated by an experimental study conducted with the EC-funded Powered Two Wheeler Integrated Safety (PISa) test bike.

Emergency braking performance of motorcycle riders: skill identification in a real-life perception-action task designed for training purposes

TL;DR: The results indicate that PTW rider performance may be assessed in a reliable and objective way using the combination of vehicle kinematics and human performance measures and indicate the lack of correlation of both years of riding experience and overall riding skill with an objective measure of emergency braking performance such as effective deceleration.

The Stability and Control of Motorcycles
TL;DR: In this article, mathematical models of a motorcycle and rider dependent on three alternative assumptions concerning the tyre behaviour were developed. Stability characteristics deduced from them are compared, and m... and m...
Stability and control of motorcycles
TL;DR: In this paper, the authors developed a mathematical model of a MOTORCYCLE and a RIDER with three alternative assumptions concerning the treetrain behavior of the vehicle. But the main conclusion is that the FIXED control CHARACTERISTICS of the MOTOR CYCLE are not of primary importance, and the STEADY state response to STEERING TORQUE is of secondary importance.
