DETROIT – Five innovation drivers are producing new competencies, technologies and competitors that will transform a brake-system value chain that has existed for decades.
These five innovation drivers will have a major impact on how vehicles operate and how automakers and brake-system suppliers do business. Cooperation is one of the models that will allow companies to survive in the new ecosystem, and in fact, traditional and new players already are cooperating in defining future vehicle architecture.
The five innovation drivers and their impact on automotive braking, include:
A cooperative model will have a major impact on a new ecosystem that is allowing suppliers to survive and to help define future vehicle architecture.
Electrification and Emissions Reduction
It’s difficult to have missed the industry push toward battery and fuel-cell vehicles. Vehicles of this type are increasingly attractive because they offer higher energy efficiency, lower emissions and greater energy diversity. Bloomberg projects that 24 percent of new car sales will be battery electric vehicles (BEVs) by 2030. As a driver for brake technology, electrification – along with emissions reduction – is helping increase adoption of electromechanical parking brakes and regenerative braking technologies. Low-drag solutions that reduce CO2 and optimize EV mileage, as well as reduce noise and brake dust, are major factors here. Some 50 percent of cars produced by 2028 will include electromechanical parking brakes, and 20 percent will feature EBB.
Autonomous vehicles will evolve over time through different automation levels (from L1 to L5) until 35 percent of new cars will be level 3+ by 2030. These vehicles will include automated emergency braking; redundancy in architecture; hardware and software robustness, and will use a systems approach to brake-by-wire solutions.
In short order, vehicle connectivity will move to Vehicle-to-Infrastructure (V2I) and Vehicle-to-Vehicle (V2V) technologies so that every car may know precisely where every other car is on the road. With this great burst in technology will come brake systems that are compatible with cyber security, as well as being connected to allow smart maintenance (pad wear sensors).
Emerging pay-per-use and shared mobility will evolve to include smartphone integration that can intuitively summon robocabs. Pay-per-use and shared mobility will earn 40 percent of automotive profits by the 2030 timeframe. Because robocabs will operate 24/7 in this new transportation world, braking systems will be engineered for increased durability with hardware optimized for easy maintenance, including pad replacement.
Current regulations and design trends will force a move to even stronger and lighter materials that will reduce vehicle weight without sacrificing passenger safety. Requirements for packaging optimization, weight reduction and increased brake performance will result in the use of aluminum in about 25 percent of all brake calipers by 2028.
To meet future requirements for performance, durability and weight reduction for braking systems by 2030, the industry will move to a true brake-by-wire smart brake concept, that will provide a dry (fluidless) solution with redundancy on all four wheels. These new systems will require a plug-and-play configuration that enables new chassis-function architectures.
