X-by-wire, or drive-by-wire system is the use for electro-mechanical technology in cars, to replace mechanical linkages. Electric components are used in sensors, batteries, actuators, fuel injections, etc., and a combination of these components with human-machine interfaces to reduce the time taken to perform certain functions. This technology helps in replacing traditional components such as steering column, intermediate shafts, pumps, hoses and others from the vehicle.
There are different types of X-by-wire technologies in the marketplace like Throttle-by-wire Systems, Brake-by-wire Systems, Steer-by-wire Systems and Park-by-wire Systems. At present these x-by-wire technologies are implemented separately in the engine control, braking or steering system. The X-by-wire technology has been in use in aerospace and is now finding its applications in automotive. One of the major factors which is helping the automotive manufacturers to incorporate this feature in vehicles is availability of variety if semiconductor ICs that are cheap and can meet the cost targets to provide control, power and communications required for these systems.
Reduction of mechanical parts replaced by electrical systems also contributes in making vehicles lightweight, thereby improving fuel efficiency of cars, a condition that has been mandatory in most developed and several developing countries in the world. It is clear that going forward, as these technologies become more efficient and affordable, and fuel efficiency laws become comprehensive and stringent globally, the market for X-by-wire systems is bound to grow. The car manufacturers who will implement this would also enjoy a substantial per vehicle cost savings to boot. The X-by-wire global market is worth US$ XX.XX bn in 2015, and is expected to reach US$ XX.XX bn by 2020, at a CAGR of X.X%.
Some of the vendors mentioned in the report are Nissan, Peugeot, Audi, RLP Engineering and TRW.
Increasing focus on fuel efficiency, advancements in research maximizing the marginal time savings by substituting mechanical linkages with electrical ones, decrease in cost as the systems become mainstream gradually, and some other factors drive the X-by-wire market globally.
High cost of systems and associated components, ongoing research, insufficient stress on fuel efficiencies in several developing economies across the world, and inadequate adoption of fuel efficiencies in countries with laws in place are some of the bottlenecks of the X-by-wire global market.
