Modern computerized car require a secure-by-design platform. And that’s just what we’ve come up with.

Quite a lot of folks seem to think that the automobile of the 21st century is a mechanical device. Sure, it has added electronics for this and that, some more than others, but still, at the end of the day – it’s a work of mechanical engineering: chassis, engine, wheels, steering wheel, pedals… The electronics – ‘computers’ even – merely help all the mechanical stuff out. They must do – after all, dashboards these days are a sea of digital displays, with hardly any analog dials to be seen.

Well, let me tell you straight: it ain’t so!

A car today is basically a specialized computer – a ‘cyber-brain’, controlling the mechanics-and-electrics we traditionally associate with the word ‘car’ – the engine, the brakes, the turn indicators, the windscreen wipers, the air conditioner, and in fact everything else.

For example: in the past the handbrake was 100% mechanical. You’d wrench it up – with your ‘hand’ (imagine?!), and it would make a kind of grating noise as you did. Today you press a button. 0% mechanics. 100% computer controlled. And it’s like that with almost everything.

Now, most folks think that a driver-less car is a computer that drives the car. But if there’s a human behind the wheel of a new car today, then it’s the human doing the driving (not a computer), ‘of course, silly!’

Here I go again…: that ain’t so either!

With most modern cars today, the only difference between those that drive themselves and those which are driven by a human, is that in the latter case the human controls the onboard computers. While in the former – the computers all over the car are controlled by another, main, central, very smart computer, developed by companies like Google, Yandex, Baidu and Cognitive Technologies. This computer is given the destination, it observes everything going on around it and then decides how to navigate its way to the destination, at what speed, by which route, and so on based on mega-smart algorithms, updated by the nano-second.

A short history of the digitalization of motor vehicles

So when did this move from mechanics to digital start?

Some experts in the field reckon the computerization of the auto industry began in 1955 – when Chrysler started offering a transistor radio as an optional extra on one of its models. Others, perhaps thinking that a radio isn’t really an automotive feature, reckon it was the introduction of electronic ignition, ABS, or electronic engine-control systems that ushered in automobile-computerization (by Pontiac, Chrysler and GM in 1963, 1971 and 1979, respectively).

No matter when it started, what followed was for sure more of the same: more electronics; then things started becoming more digital – and the line between the two blured. But I consider the start of the digital revolution in automotive technologies as February 1986, when, at the Society of Automotive
Engineers convention, the company Robert Bosch GmbH presented to the world its digital network protocol for communication among the electronic components of a car – CAN (controller area network). And you have to give those Bosch guys their due: still today this protocol is fully relevant – used in practically every vehicle the world over!

The Bosch boys gave us various types of CAN buses (low-speed, high-speed, FD-CAN), while today there’s FlexRay (transmission), LIN (low-speed bus), optical MOST (multimedia), and finally, on-board Ethernet (today – 100mbps; in the future – up to 1gbps). When cars are designed these days, various communications protocols are applied. There’s drive by wire (electrical systems instead of mechanical linkages), which has brought us: electronic gas pedals, electronic brake pedals (used by Toyota, Ford and GM in their hybrid and electro-mobiles since 1998), electronic handbrakes, electronic gearboxes, and electronic steering (first used by Infinity in its Q50 in 2014).
