System takes control of the pedals leaving the driver to steer

Walk up to most people and ask what they think of when the name Porsche is uttered and many will immediately think 911 and racing. Porsche is getting further and further from its pure sports car roots even though it still makes some of the best sports cars around. Most of the Porsche models sold today aren't the sports cars the company currently makes (911, Boxster, Cayman), but larger vehicles like the Panamera sedan/hatchback, and Cayenne crossover.

While performance remains a priority for Porsche, the company is looking into ways to make all of its vehicles safer and more efficient. Part of the investigation into efficiency and safety is a new system that takes adaptive cruise control a lot further than simply being able to slow down a vehicle in emergency situations.

The new system Porsche is working on is called ACC InnoDrive and it completely removes the driver's feet from the pedals. The car learns the route the driver takes complete with estimates of the speed limit, curves, and elevation changes and then translates that into data the car uses to completely control the pedals.

The goal is to create a car that constantly monitors speed, throttle, and other aspects for a smooth and comfortable ride that optimizes efficiency. Autoblog was able to take a ride in a prototype Porsche Panamera S that is equipped with the system. The hardware to make the ACC InnoDrive function is a second ECU in the trunk of the car that gathers additional data. 

Autoblog says that allowing the car to take over the pedals completely was unnerving in some parts, but the system performance flawlessly.

ACC InnoDrive has three modes: Comfort, Dynamic, and Off. The Dynamic mode is where the pedals are taken over by the car. Apparently, the system will bring your car to a complete stop, slow for curves, and knows the speed limit so you just have to steer. The system is expected to be production-ready in about three years and of course will be optional. InnoDrive is expected to be offered on most Porsche vehicles, including its sports cars.

Porsche did note that its system would not touch the steering wheel. It feels the hands-on aspect of steering is integral to the Porsche experience.

What about foot down on brake? I'm not worried about my normal driving patterns. I'm worried about someone else swerving in front of me and my fully automated system being unable to adjust. Sure, I can steer, but I would want full control of the gas and brakes at that point. Many drivers instinctively handle issues on the road, like deer jumping out, or stuff flying off the back of a truck. Computers should be better, but I have yet to see one that actually is.

I'd be shocked if foot on the break wasn't a method to instantly switch back to manual speed control.

Working daily with computers and humans, I can tell you that I've come to trust the machines to do their job a lot more than the humans.

Ok, but do you trust the machine to take your place, and take over for your experience?

I think a machine is much more reliable for specialized tasks like this one.

Obviously they need some method of disabling computer control just in case, but I'd trust computers more than I'd trust the average person to pay attention to the road, especially with how popular texting and internet browsing on phones have become.

Exactly a few well placed ultrasound sensors in your car and you could detect all incoming objects and the computer would do a much better job choosing what to do and faster.
For instance if a deer jumps into the road chances are you will not see it coming, with sensors the computer could be aware if it and warn you or takeover and do what needed to reduce the risks of an accident!

From reading this brief synopsis, it seems as if the pedals are still there and the InnoDrive needs you to drive the route at least once before the car can do it.

It is a nice idea, not relying on GPS and maps that could be wrong, and a computer that knows the upcoming terrain can probably drive more efficiently than a person.

And with all other Cruise Control Systems there will be the disclaimer that the driver should still pay attention and be prepared for the dynamic situations that arise while driving.

It will work ok where you have long drives with no intersections. I wonder what it does when you come to the places you have to stop and wait for crossing traffic, or things like rail crossings? Those are variables it just can't learn and are part of many peoples daily commutes.

What'll be really interesting to see (from a legal perspective) is what happens the first time a pedestrian is struck and killed by one of these things... Is it Porsche's fault or the "drivers"?

Morally I'd say the driver, considering they are the one who pressed the button and took their eyes off the road. That being said, in America it's usually whomever has the deepest pockets..
