I am sure the Nissan engineers have figured out the response characteristics of the wired steering systems vs. the mechanical one so the driver will notice little change when the backup / redundant system takes over. But the situation described by @Ian McMillan above does bring up an important issue. It would be nice to know more about this.
I like the idea of compensating for cross-winds; but experience in the aircraft industry (which uses triple-redundancy) has shown that unless fly-by-wire has some means of being very quickly by-passed when the voting circuit makes a mistake, you can find yourself in real trouble real quick. Split-second timing can be vital, can be life-and-death... I still feel the butterflies there
Drones are, in essence, flying autonomous vehicles. Pros and cons surrounding drones today might well foreshadow the debate over the development of self-driving cars. In the context of a strongly regulated aviation industry, "self-flying" drones pose a fresh challenge. How safe is it to fly drones in different environments? Should drones be required for visual line of sight – as are piloted airplanes? Join EE Times' Junko Yoshida as she moderates a panel of drone experts.
