In any brake system of an automobile or passenger vehicle, an increase in Master/Wheel cylinder diameter ratio leads to an increase in brake efficiency. This paper focuses on Master/Wheel cylinder diameter effect on the brake efficiency. A VISUAL BASIC computer code was developed for computation of Master/Wheel cylinder diameter ratio corresponding to break efficiency. Aided by the developed so...

Rear-end collisions and distraction are major concerns and basic research in cognitive psychology concerning attention in visual search is applicable to these problems. It is proposed that using yellow tail lamps will result in faster reaction times and fewer errors than current tail lamp coloring (red) in detecting brake lamps (red) in a "worst case" scenario where brake lamp onset, lamp inten...

Standard incandescent brake lamps have a relatively slow rise time. It takes approximately a quarter of a second for them to reach 90% of asymptotic light output, causing potential delays in responses by following drivers. The present study evaluated reaction times to brake signals from standard incandescent brake lamps and from three alternative brake lamps with substantially faster rise times...

Rear-end collisions and distraction are major concerns in automotive transportation. This study investigated the conspicuity of current rear automobile lighting (red brake and red tail lamps) compared to a proposed arrangement (red brake lamps with yellow tail lamps) in a task where participants only had time to perform one saccade and fixation (200ms) to identify the presence or absence of bra...

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...

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...

There are several kinds of metrics should be handled by the brake system of hybrid electric vehicles such as fuel economy, performance and safety. The optimal control of the HEV brake system will be solved by a modelbased approach. Based on the developed vehicle model, a two phase approach is proposed for the coordinated control of the HEV brake system. A high level sliding mode controller is a...

The paper includes the second part of an investigation of the braking process of railway vehicles, dealing with the temperature distribution of a brake block in various load cases and the FE analysis of the phenomenon of thermal elastic deformation. Thermal expansion calculations pointed out to the fact that in case of the contact area, the radius of the operating surface of the brake block inc...

Brakes and tires are the major contributors for catastrophic failure of ground vehicles. Braking system is the utmost important besides tire to ensure the safety of users and vehicle. Ensuring good condition of brake lining is very crucial to ensure the efficiency of the braking system, where, the worn off brake lining not only endangers life but also damages the entire brake associated parts s...
