Will Fly-by-Wire Systems Transform Vehicles Beyond Airplanes?

The advancements in technology have significantly reshaped the industry, particularly in the realm of self-driving vehicles. While Tesla and Waymo are leading the charge towards autonomous driving, the question remains: will the fly-by-wire systems from aviation eventually become standard in other types of vehicles? This innovative technology, first pioneered for aeroplanes, is now poised to revolutionize the automotive industry.

Current Use of Fly-by-Wire in Modern Vehicles

Nearly all modern cars are already incorporating fly-by-wire systems, primarily through electronic gearboxes and braking mechanisms. The gas pedal, in particular, has long been replaced with an electronic actuator, reducing the need for mechanical connections. Similarly, fluid or electronic power steering has replaced the traditional mechanical steering system, enhancing driver convenience while maintaining safety.

Future Possibilities in Advanced Vehicles

As we look towards the future, the integration of fly-by-wire systems in self-driving cars and trucks is anticipated to be even more advanced. Unlike simple electronic actuation, these systems use sophisticated algorithms to take into account various factors such as vehicle speed, road friction, spring compression, throttle position, weight, temperature, and wheel speeds to determine optimal actuator settings. This level of complexity is already seen in some models from luxury brands like BMW, Mercedes, and Audi.

Challenges and Considerations

While the technological advancements are promising, there are several challenges that need to be addressed. The US Navy's experience with fly-by-wire in warships highlights the potential for accidents, with the USS Fitzgerald and USS Jackson colliding in 2017 and 2018, respectively. This has led to a reevaluation of the design, emphasizing the importance of tactile responses.

Furthermore, the adoption of fly-by-wire systems in motor vehicles would require significant changes in regulations and licensing. For instance, drivers might need to obtain multiple licenses, or a similar system to that of pilots, where there would be specific certifications required for different types of control systems. This could lead to a more stringent approach towards licensing and safety, reducing the risk of accidents caused by drivers operating without the proper qualifications.

The Vision for the Future

The vision for the future of fly-by-wire systems in vehicles is ambitious. Imagine a cockpit similar to that of an F-16 or F-18, complete with ejection seats for added safety. The control systems could be designed with T-Bar mechanisms like those in battle tanks or levers like those on bulldozers or lawn mowers. For those who are not accustomed to such systems, there could be an easy transition through a process similar to obtaining a pilot's license, where a license can be swiped like an ATM card to unlock the vehicle's systems.

The road to achieving this vision is complex and fraught with challenges. However, with the right design and implementation, such systems could revolutionize the driving experience, providing a safer, more efficient, and more responsive interface for the driver.

Conclusion

The future of fly-by-wire systems in vehicles is not just a possibility; it is a necessity for the advancement of self-driving technology. With the appropriate design and regulatory framework, we can expect to see significant changes in the way we interact with our vehicles, making them safer and more reliable.
