Design and validation of a multi-body model of a front suspension bicycle and a passive rider for braking dynamics investigations
TLDR
In this article, the authors present a Multi-Body Model (MBM) of a front suspension bicycle and a passive rider, which can be used as a virtual representation of the plant for the model-based design process of the BDA.Abstract:
The global spread of Electric Bicycles (EBs) is increasing more and more. In addition to supporting the ease of cycling, the electric energy available can also be used for innovative braking control systems. The project BikeSafe picks up on this idea and aims at developing an active Braking Dynamics Assistance system (BDA) for EBs equipped with hydraulic brakes. A simulation model taking into account all substantial braking dynamics influences is necessary for the model-based design of the BDA. This paper presents a Multi-Body Model (MBM) of a front suspension bicycle and a passive rider. This MBM has been experimentally validated for in-plane braking dynamics using road tests. It has real-time ability and can therefore be used as a virtual representation of the plant for the model-based design process of the BDA.read more

A Multibody System Approach for the Systematic Development of a Closed-Chain Kinematic Model for Two-Wheeled Vehicles
TL;DR: The kinematic model developed in this work is general and, therefore, it is suitable for describing the complex geometry of the motion of both bicycles and motorcycles and compares favorably with those found in the literature about vehicle kinematics and contact geometry.

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.
