In recent years, cars have evolved from purely mechanical to veritable cyber physical systems that generate large amounts of real-time data. These data are instrumental to the proper working of the vehicle itself, but make them amenable to a multitude of other uses. For instance, GPS information has recently been used for a large number of mobility studies in the academic community , , as well as to feed traffic apps such as Google Traffic and Waze. This use of vehicle data is already having a profound impact in science, industry, economy, and society at large. Now, imagine that instead of accessing one single source of vehicle-generated data (GPS), one can access the entire wealth of data exchanged on the controller area network (CAN) bus in near real time amounting to over 4000 signals sampled at high frequency, corresponding to a few gigabytes of data per hour. What would be the implications, opportunities, and challenges sparked by this transition?

People’s driving behavior is in!uenced by different human and environmental factors, and several attempts to characterize it have been proposed. Nowadays, the standardization of the CAN bus and the increase of the electronic components units in modern cars over a large availability of sensors data that make possible a more reliable and direct characterization of driving styles. In this work, we propose the concept of “Driving DNA” as a way of describing the complexity of driving behavior through a set of individual and easy-to-measure quantities. These quantities are responsible for some aspects of the driver’s behavior, just as – in the metaphor – genes are responsible for the tracts of an individual. The concept has been tested on a dataset collected from the CAN bus consisting of more than 2000 trips performed by 53 people, in a wide scenario of road types and open tra#c conditions. The Driving DNAs have been calculated for each person, and a graphical visualization of their comparison is provided.

Car safety tech is something that we got used a pretty while ago, but when it comes to ADAS (advanced driver assistance systems), the situation changes, as not everyone knows what this actually means. To get you more familiar with the topic, we will tell you that ADAS is made of various systems and features, which allow the driver to have essential information, and autotomize complicated or repetitive tasks. Then end goal of this advanced system is an overall increase in car safety for both the driver and his passengers and everyone else around. Since there are many versions of such systems, seeing how they actually relate to safety is not always the most simplest of tasks.
Parts of ADAS have been present for a while now, and many of them have over time, proven to be quite an improvement when it comes to driving experience or the road safety. Even though this system keeps changing and evolving every year, there are thirteen most important features you need to be familiar with next time you plan on buying a smarter than the average car.
Those features are:
In this article, we will talk about Adaptive cruise control, what comes with this system, what are the benefits, and if there are any cons.
Adaptive Cruise Control
This ADAS feature is the most handy when it comes to driving on the highway, where, otherwise, you are in charge of continuous monitoring of your cruise control systems if you want to stay safe. Now, the ACC comes as the next step in the car safety evolution, and allows automated speed management of your vehicle. Thanks to this system, your car is capable of automatically slowing down or picking up speed, all as a reaction to what is going on in front of you.
For example, if you are driving in a group of vehicles, and if the first one in line starts going slower, the ACC will match the speed of the first vehicle, on its own. When the vehicles in front of you, start going faster, the system will increase the speed of your car automatically.
Also worth mentioning is that most of ACC systems are made so that they shut off automatically, if the speed of your vehicle reaches a certain speed threshold, however, some systems stay active in stop and go type of driving as well.
Now, so far we have learned what advanced driver assistance system is, what different systems it includes, and presented the first one of them. To keep the story going, we decided to do a follow up article, where we will continue talking about the ACC, how it works, and what types there are.
Advanced Driver Assistance Systems (ADAS) built into New Zealand's new vehicles are becoming more and more evident. Most car manufacturers are beginning to roll out their higher end car models with some type of advanced driving assistance, and while this provides a future of safer cars and driving for those who can afford a new car, statistics show New Zealanders are twice as likely to buy an older second hand car without ADAS .
Roll on the app age
Distinctions between more affordable mobile app driver assist technology and car manufacturer built-in ADAS is becoming less obvious. The ability for mobile apps to perform as an effective ADAS creates a wide market opportunity for older vehicles and driving assistance. The product Safety Lens made by General Magic is one such ADAS that is functional and cost effective. It provides driver assist for risk in following distance, lane position, traffic sign recognition, pedestrian collision and congested traffic assist. Safety Lens works in day/night, dry and wet conditions making it a sophisticated app.
Review: General Magic iPhone Car Mount System Helps You Drive Safely
By Todd Bernhard on Thu, 02/16/2017
I have been a fan of General Magic since the Apple Newton days. But like the Newton, they went away for a while. Now they are back, with a successful Kickstarter campaign under their belt for a totally new product, Safety Lens ($99.99). Safety Lens is a combination magnetic car mount, magnetic iPhone case, and an intelligent app.
The case itself is pretty bare bones. It is clear plastic with four rare earth magnets on the back, strategically positioned to connect with four other magnets on the car mount. That car mount can be attached to the windshield, or, using the included adhesive disc, to the dashboard. The mount can accommodate the case in portrait or landscape mode, but you will want it in landscape. That lets it become an intelligent GPS device. It's intelligent because the Magic Earth Pro app can download maps for offline use (via in-app purchases) and leverage the iPhone's sensors and camera. This allows the app to alert you when your speed exceeds the posted limit or if you drift out of your lane, or if you are too close to the car in front of you.
Such features are available in high-end cars, often as part of a $1,000-plus package. Now, you can add this functionality for 90 percent of the cost. All that sensor activity is going to put a drain on your battery, so you will want to plug in the phone using a car charger. There is also Bluetooth integration so voice prompts are broadcast on your radio, as well as the Apple Watch. Like Apple Maps in iOS 10, the app recognizes where you are when you disconnect from Bluetooth so you can find your car when you return to the parking lot.
I would prefer that the case were more protective as it's not the case I would want to walk around with, but for driving purposes it's fine. Maybe a mount that accommodated a phone in a case would be a good fix. Also, you miss out on Siri integration, which would be nice because the phone is out of arm's reach when mounted. It would be nice to say "Hey Siri, I need directions to ..." which you can do now, but it will use Apple Maps, not the Magic Earth app.
I must admit the app has already corrected some of my bad habits. It warned me when I was drifting over the yellow line and if my speed was too aggressive. You can adjust the sensitivity of some alerts, so this could be a good accessory for parents to setup for their teenagers. Perhaps the best part is by having the phone just out of reach, there's less likelihood of using it for texting, etc.
If you are want a smart car, but are on a budget, for $100, General Magic can make your car smarter and safer.
