Self-Driving Cars, Arriving One Bit At A Time

The concept of a car that makes all the decisions and drives itself has always been intriguing, and a distant look into the future of technology. But while we were dreaming of that future computer-controlled robot car, more and more intelligent sensors and computer assisted steering, braking, suspension and navigation have crept up on us.  By now, top-end luxury sedans are not exactly self-driving, but definitely
a collaboration between the car and driver.

The latest generation of the Mercedes S-Class is the best example out there in the market. It comes with a suite of features, some standard and others extra-price options, called Intelligent Drive.  This system can work wonders, spotting and distinguishing between humans and animals in the road ahead, sensing potholes, and using radar to read any anomalies in the movement of the car ahead and even the car in front of that.
It then takes command of suspension hydraulics, speed control, braking, and even the headlights to adapt to every variation that would normally be left to the driver's senses and reflexes.  The future isn't here yet, but it's close enough for us to get a good look at it.

Excerpt: "The truth is, autonomous cars have been arriving in bits and pieces for years. Bristling with sensors and microprocessors, cars — especially at the top end of the price spectrum — have long been lightening the driver’s workload and improving safety with features like parking assist, lane-departure warning, adaptive cruise control and various crash-avoidance technologies.

More bits of autonomous driving technology are arriving in the new model year.

'We’ve given the vehicles senses,' Ralf G. Herrtwich, director for driver assistance in the advanced engineering group of Daimler, the parent company of Mercedes-Benz, says in a video presentation for reporters. 'They can see and do so much more.'

The car Dr. Herrtwich speaks about is the 2014 Mercedes S-Class, which arrived at United States dealerships this month. The car makes a significant step toward the ability to drive autonomously, using many types of sensors to gather data about driving conditions, including a stereo camera that lets it 'see' by providing 3-D images, akin to human vision.

The new S-Class — an S550 and S63 AMG are first to arrive in the United States — offers a package of technologies, some of which are extra-cost options, that Mercedes calls Intelligent Drive. Among its many components are systems that can steer, brake, cover blind spots and watch for pedestrians and animals. One function monitors the road ahead to ensure that passengers are not jolted by potholes.

Dr. Herrtwich points out that the car’s computing power, in the form of processors and algorithms, is highly developed.

'Our Intelligent Drive Systems these days are capable of analyzing complex traffic situations, and they have developed an understanding for what to do,' he says.

It is a network of sensors that makes the analysis possible. Most perform multiple functions, generating data for a number of driver-assistance systems.

Included are numerous cameras, mounted front, rear and side. Among them are two forward-facing infrared cameras for night vision, and a stereo camera — actually two cameras in a single housing — that provides 3-D imaging crucial to the system’s decision-making powers."
