Software development has progressed to a state where the engineer needs to input only base information and the result is provided by an appropriate program. This is excellent for time savings within the industry but a complaint by many senior engineers is that new recruits can readily operate the programs but rarely understand the fundamentals driving that program. As such they are not able to modify, develop or “tune” it to suit the differing needs of a company and indeed “add to” or move towards optimizing a brake design. More important is that there is a blind faith in the answer with little recognition of potential issues – NVH being at the forefront of many braking problems.
This presentation will consider the important aspects of brake design – brake sizing, load transfer & brake balance, electronic braking distribution (EBD), ABS, thermal aspects& NVH. There will be consideration given towards electric braking including energy recovery systems. It is expected that a case study of a tractor/semi-trailer will serve to demonstrate the difficulties of brake design when the load magnitude and position is generally unknown. Such situations demand a common approach (a standard) but this tends to existing problems not being addressed – trailer slew, jackknifing and rollover.
The process of vehicle emission reduction had a long time only the engine in focus. With the new emissions standards, the engine emissions are lower than the emissions generated by abrasion of tires and brakes. Consequently, R & D now turn to the brake missions. In many places now objectified measurement standards for brake particle emissions will be developed.
An analytical approach evolves from the boundary layer dynamics of brake pads, which reveals more and more the central role of wear for the emergence of friction and emission dynamics.
The talk will concentrate on European activities in measurement and show some new research activities in emission generation by friction in brakes.
Friction materials generally may contain up to 20 different ingredients. Considering that each raw material has its intrinsic variability, the effects that the variability can generate on the final product are evident if there are no well defined strict tolerances on the characteristics under control.
The ingredients used for the preparation of friction material (NAO or Low Met or Semi Met) can be divided in few categories: binders, metals, fibers, fillers, abrasives and lubricants. Tolerances are defined based on laboratory analysis and technical papers of the suppliers. Each ingredient has a specific role and can modify the characteristics of the final product. Density, porosity and compressibility can be influenced by phenolic resin variability, while friction level can be modified by different lubricant / abrasives ratio.
Mechanical strength depends on fiber type and content (metallic, inorganic and organic). The control of the incoming batch of raw materials is mandatory to maintain under control all the characteristics of the friction material and prevent issues in the market.
We need the brake in vehicle to bring it to a halt, or to reduce speed while travelling. While the concept is rather simple, what happens in the real world is a totally different story. Philosophically, we allow human to operate road vehicle (“the machine”) without so much restrictions or control as in the aviation industry or even in maritime. Humans are weak when they are exposed to power (speeding over the limit), easily get distracted, and being too optimistic and over confident. All these bad qualities in the road safety system originating from human have made the system not sustainably safe. The inventions on braking technologies today are actually responding to the above mentioned problems, and this includes the idea to have autonomous vehicle. The available technologies are centered on the effort to overcome the weaknesses of human beings, e.g. to assist drivers to brake on time, to estimate and reduce headway distance, etc. It is predicted that in the (near?) future, humans do not need to drive a vehicle; hence, the future of braking technologies should no longer consider human factors in the entire design.
Brake friction materials are being developed for safety and durability , and now more and more concerns are being expressed regarding NVH. Car users always blame friction materials manufacturers when these issues occur. For addressing all of these concerns, not only friction materials need to be improved, but brake repairs and maintenance are also main causes of many brake concerns. This panel discussion will provide some of the case studies by aftermarket leaders in each specific region which might have different braking behaviors and different concerns in order to explain how brake repair services can affect brake performance.

One of the most important latest technological changes in global automotive industry is the development of Electric Vehicles. The technical advantages of electric vehicles include greatly reduced petroleum use, reduced exhaust emissions and reduced air pollution. Electric vehicle population is increasing rapidly with growing demand globally and worldwide government support. The panel discussion will provide information about electric vehicle trends globally and electric vehicle braking concepts. Some of the major car makers will update their electric vehicle policy.
