In order to decide where to exit blood vessels and enter tissues, leukocytes roll along endothelial surfaces. Recent studies suggest that an 'automatic braking system' (ABS), involving selectin cell-adhesion molecules, enables leukocytes to roll at a fairly constant velocity despite large variations in blood flow rate.

There exist several problems in the control of brake systems including the development of control logic for antilock braking systems (ABS) and “base-braking.” Here, we study the base-braking control problem where we seek to develop a controller that can ensure that the braking torque commanded by the driver will be achieved. In particular, we develop a “fuzzy model reference learning controller...

In the past four Years, Road Traffic Injuries (RTI) ranked fourth among the leading cause of death. Nearly 1.3 million people die every year on the world’s roads and 20 to 50 million people suffer non-fatal injuries, with many sustaining a disability as a result of their injury. However, active safety systems like ABS (Anti−lock Braking System) and ESP (Electronic Stability Program) offer possi...

A general optimal control problem for ABS is formulated and analyzed, with the elimination of excessive slip and reduction of braking distance taken into account. Analytical formulas for singular optimal solutions are derived. These results are applied to a simple laboratory model of ABS. The results of simulations are compared with those obtained by a gain-scheduling approach. Copyright © 2005...

An antilock braking system (ABS) can ensure that the wheels are not locked during process which is an important to safety of braking. Regenerative also a crucial for hybrid vehicles and helps improve cruising range car. As such, coordinated control ABS research direction. This paper researches regenerative in vehicle based on composite structure motor (CSM-HEV). Firstly, two new modes engine-mo...

In this paper we derive a new dynamic friction force model for the longitudinal road/tire interaction for wheeled ground vehicles. The model is based on a dynamic friction model developed previously for contact-point friction problems, called the LuGre model [7]. By assuming a contact patch between the tire and the ground we develop a partial differential equation for the distribution of the fr...

We propose a simple rubber friction law, which can be used, for example, in models of tire (and vehicle) dynamics. The friction law is tested by comparing numerical results to the full rubber friction theory (Persson 2006 J. Phys.: Condens. Matter 18 7789). Good agreement is found between the two theories. We describe a two-dimensional (2D) tire model which combines the rubber friction model wi...

A literature review of advanced technology braking systems and vehicle stability control systems available or under development around the world was undertaken. Literature on the range of devices available as well as their likely effectiveness in preventing crashes and injuries was sought from a range of scientific and engineering sources for the review. In addition, an analysis was also perfor...

Control Systems such as Anti Lock Brake Systems (ABS) and Traction Control Systems (TCS) are vastly used in most vehicles as to enhance the safety of the systems. These systems have many virtues on controlling the dynamics of vehicles, but they only control the longitudinal dynamics of the vehicle directly and the lateral dynamics of vehicle is not controlled because they do not receive any fee...

In this paper, an antilock–antiskid braking system controller, which has been designed for stability enhancement of vehicles during braking and turning, is presented. Using available signals, a novel structure is proposed for vehicle stability improvement for critical driving conditions such as braking on slippery or μ-split road surfaces. In conventional vehicles, undesired lane changes may oc...
