Automotive Grade Linux might save your life

A standard Linux-based software platform for the connected car would be huge, and at this point could even be a life-saving development.

Automotive Grade Linux is a collaborative open source project developing a common, Linux-based software stack for the connected car. The community’s first open source software release is now available for download, bringing the industry one step closer to realizing the benefits of open automotive innovation.

Recent Windows-based dashboards (for example the Nissan Leaf) are an abomination only slightly less dangerous than even-more-hideous automaker proprietary dashboards (for example the Toyota Prius Plug-in). With all the data that exists about the dangers of distracted driving, and state legislatures passing draconian laws against texting behind the wheel, why is it legal for auto vendors to create these potentially lethal user interfaces? How can a pure touch-screen interface, that must be visually examined to be used, possibly be less dangerous than texting while driving? I can drop or ignore a smartphone, or just turn the bloody thing off, but I am forced to interact with my dashboard!

A step in the right direction is to open up the dashboard software ecosystem, so sane designs have an opportunity to compete for driver approval. After all, you can’t expect the same people who designed backwards fake stickshifts (as commonly found in Nissans and Toyotas) to create a good user interface; these people have already demonstrated that they aren’t capable of understanding the task, much less reaching the goal. But a robust community of Open Source hackers would allow the computerized automotive dashboard to progress in the same way that automobile clubs, hot rod enthusiasts, and similar communities have driven innovation historically in the rest of the car industry – by finding more alternatives, and demonstrating them in action.

For every good design there will probably need to be a lot of bad ones. Let’s stop limiting ourselves to the bad (are you listening, Ford?) and start working on a dashboard that’s less likely to kill people.

Toyota linear generator

Crankless linear motors are not new, but haven’t been very successful historically. Not only are they more difficult to engineer than crankshaft engines, they also haven’t generally been as useful because what we’ve needed has usually been rotating forces, like for example to drive wheels and generators.

But Toyota has wedded the linear motor with a linear generator that reminds me of the (awful, don’t buy one) shake-light and adapted it to power generation for series hybrid vehicles, where it makes a suprising amount of sense.

A series hybrid is one where only the electric motor ever powers the wheels directly; the fuel-burning engine runs a generator to provide electricity rather than motive power. A parallel hybrid is one where the fueled engine and the electric motor are both always driving the wheels. The Prius is neither, which is why the Prius was such a gamechanger for hybrid vehicle technology.

Other researchers have noted the ability of modern fuel injection systems to compensate for most of the traditional problems of crankless linear engines, and built multi-fuel versions.
