03 Jun 2013TL;DR: In this article, a method/controller for operating a vehicle regenerative braking system by operating in a first braking mode, in which a generator braking torque of a generator is not zero and is equal to a first regenerative portion predefined for the first mode, is presented.
Abstract: A method/controller for operating a vehicle regenerative braking system by operating in a first braking mode, in which a generator braking torque of a generator is not zero and is equal to a first regenerative portion predefined for the first mode, and controlling the system out of the first mode into a second braking mode having a second regenerative portion, which is smaller than the first portion, so that brake fluid is pumped out of a storage volume of the system into at least one wheel brake cylinder and/or at least one brake circuit of the system via at least one brake fluid delivery mechanism; by activating the delivery mechanism via a setpoint delivery output variable, which is established/predefined for a setpoint brake pressure having a setpoint pressure rise which increases over time, so that an actual brake pressure having an actual pressure rise increase over time is built up.

TL;DR: 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.

TL;DR: A control circuit which permits a direct current motor to operate during traction or during braking in such a manner that energy can be either dissipated or recovered is described in this article, which embodies gradual, continuous, and reversible shifting from one form of braking action to another.

29 Jul 2010TL;DR: An integrated controller of semi-active suspension system and vehicle anti-lock Braking System (ABS) using a quarter-car model and a single wheel-car braking model is built on the basis of the sliding mode control theory as discussed by the authors.
Abstract: An Integrated Controller of semi-active suspension system and Vehicle Anti-lock Braking System (ABS) using a quarter-car model and a single wheel-car braking model is built on the basis of the sliding mode control theory. The adjusting of the suspension control system aims at improving suspension performance as well as the braking force while braking. The adjusting of the ABS aims at getting the optimal sliding rate of the wheel and advancing braking performance. SIMULINK software is used to verify the effectiveness of the integrated controller in the normal driving condition and the braking condition. The simulation results show that when in normal driving condition, the Body Acceleration, the Suspension Working Space and the Dynamic Tyre Displacement were effectively inhibited, and the vehicle's ride and comfort were significantly improved; While in braking condition, the integrated controller can not only effectively prevent the wheel being locked, significantly shortening the braking distance and braking time, but also can improve the vehicle's comfort. The integrated sliding mode controller shows good control performance.
