Geometric imperfections on brake rotor surface are well-known for causing periodic variations in brake torque during braking. This leads to brake judder, where vibrations are felt in the brake pedal, vehicle floor and/or steering wheel. Existing solutions to address judder often involve multiple phases of component design, extensive testing and improvement of manufacturing procedures, leading t...

This paper presents the design of a model-based supervision and diagnosis system for hydraulic and future electro-hydraulic passenger car braking systems. A state space model of the braking system has been derived, which allows calculation of the individual wheel brake cylinder pressures as well as the amount of brake fluid consumed due to faults in the braking system. Based on this model, a re...

Hydraulic brakes in automobiles play a vital role for the safety on the road; therefore vital components in the brake system should be monitored through condition monitoring techniques. Condition monitoring of brake components can be carried out by using the vibration characteristics. The vibration signals for the different fault conditions of the brake were acquired from the fabricated hydraul...

The unique concept of the Self-energising Electro-Hydraulic Brake (SEHB) uses the vehicles kinetic energy as independent brake booster by the principle of self-energisation. This paper presents a new approach for controller synthesis of SEHB using the method of input-output linearisation on basis of a complexity reduced model. Once the control design is achieved, the developed controller is ver...

Electro-mechanical braking systems (see [9], References), also referred to as brake by-wire, replace conventional hydraulic braking systems with a completely “dry” electrical component system. This occurs by replacing conventional actuators with electric motor-driven units. This move to electronic control eliminates many of the manufacturing, maintenance, and environmental concerns associated w...

Brake-by-wire is a frontier technology that will allow many braking functions to switch to electronic actuation. Its deployment will lead to more effective and safe braking systems, elimination of hydraulic technology, release of space and reduction of maintenance. Design and implementation of brake-by-wire systems has recently attracted interest from researchers in automotive and control engin...

Reducing start and stop time without destroying the pavement surface is important in enhancing productivity of double-drum roller and compact quality of asphalt pavement, but it is difficult in confirming the maximum brake deceleration or start acceleration of double-drum roller. Dynamic analysis is used in studying these questions, and a mathematic model of double-drum roller is established, b...

. In this paper we describe the development and verification of software for an automotive Brake-by-Wire System. This is a new brake system without mechanical or hydraulic backup. The system is based on a time-triggered communication architecture. The central control computer in this distributed system, called Brake-by-Wire Manager, is a redundant design in order to tolerate any single failure....

This paper describes an approach of how to estimate the vehicle velocity using additional sensors provided by the brake-by-wire actuators. The advantage of brake-by-wire actuators such as the electro-hydraulic (EHB) and the electro-mechanical brake (EMB) is that the caliper pressure or the clamping force, respectively, are known. Wheel speed, vehicle acceleration, and caliper pressure or clampi...

This paper deals with the design of a brake caliper pressure controller for a conventional ABS/ESC system and the experimental validation of its tracking performances. The analysis of the hydraulic plant, carried out in Part I of this two-part study, is here utilized to develop the control algorithm for ABS digital electro-hydraulic valves. The control strategy is based on a Feedforward (FF) an...
