どんどん活動の範囲を広げるGoogleが、今度は自動車で効率的な走行を実現するための Prediction API を発表しました。これは自動車をいつどこで運転したかというデータを収集し、分析することにより、運転時のエネルギー効率を最適化するというもの。パートナーであるフォードは、このAPIと同社自身の行動分析技術を組み合わせることで、出発時間に応じて目的地を予測するというようなことが可能になる、と説明しています。たとえば平日朝に車に乗り込めば、きっと会社に行くのだろうなとか。エネルギー効率に関していば、電気自動車専用ゾーンをハイブリッドカーで走行することになったとき、そういった条件をあらかじめ理解した上で電気 / ガソリンの利用を適切に切り替えるとか。いずれにせよ、こうした取り組みはまだ研究段階にあり、次はいかに運転データを保護していくかについて検討を行っていく予定。いわゆるスマートカーについて、自動車業界はさまざまな取り組みを行っていますが、Googleのような企業との連携が進めば、実現に向けてますます加速していきそうです。
Ford Developers Look to Use Google Prediction API to Optimize Energy Efficiency; Research Presented at Google I/O
• Ford is leveraging Google's new Prediction API to advance ongoing research in how predictive driver behavior could help optimize vehicle control systems and improve vehicle performance attributes such as fuel or hybrid-electric efficiency
• The Google Prediction API, which provides greater computation power, information storage and external data through cloud computing, can convert historical driving data – the where and when you drive – into useful real-time predictors
• Ford envisions the capability to empower vehicles to offer drivers smart guidance based on learned behaviors and a variety of captured data
DEARBORN, Mich., May 10, 2011 – Ford researchers are harnessing the power of cloud computing, analytics and Google innovation to identify technologies that could make tomorrow's vehicles smart enough to independently change how they perform to deliver optimal drivability and fuel efficiency.
Ford researchers are applying Google's new Prediction API to more than two years of their own predictive driver behavior research and analysis. The Google API can convert information such as historical driving data – where a driver has traveled and at what time of day for example – into useful real-time predictions, such as where a driver is headed at the time of departure.
"The Google Prediction API allows us to utilize information that an individual driver creates over time and make that information actionable," said Ryan McGee, technical expert, Vehicle Controls Architecture and Algorithm Design, Ford Research and Innovation. "Between Google Prediction and our own research, we are discovering ways to make information work for the driver and help deliver optimal vehicle performance."
How it works
Ford is hoping to use these types of cloud-stored data to enable a vehicle essentially to optimize itself and perform in the best manner determined by a predicted route.
This week, Ford researchers presented a conceptual case of how the Google Prediction API could alter the performance of a plug-in hybrid electric vehicle at the 2011 Google I/O developer conference. In this theoretical situation, here's how the technology could work:
• After a vehicle owner opts in to use the service, an encrypted driver data usage profile is built based on routes and time of travel. In essence, the system learns key information about how the driver is using the vehicle.
• Upon starting the vehicle, Google Prediction will use historical driving behavior to evaluate given the current time of day and location to develop a prediction of the most likely destination and how to optimize driving performance to and from that location.
• An on-board computer might say, "Good morning, are you going to work?" If the driver is in fact going to work, the response would be, "Yes," and then an optimized powertrain control strategy would be created for the trip. A predicted route of travel could include an area restricted to electric-only driving. Therefore, the plug-in hybrid could program itself to optimize energy usage over the total distance of the route in order to preserve enough battery power to switch to all-electric mode when traveling within the EV-only zone.
"Once the destination is confirmed, the vehicle would have instant access to a variety of real-time information so it can optimize its performance, even against factors that the driver may not be aware of, such as an EV-only zone," said McGee.
Because of the large amount of computing power necessary to make the predictions and optimizations, an off-board system that connects through the cloud is currently necessary.
Knowing that driver behavior and patterns correlate to overall fuel and energy efficiency during the vehicle ownership experience, Ford researchers are committed to increasing their understanding of driver behavior behind the wheel and to developing accurate protocols to predict it.
"Anticipating the driver's destination is just one way that Ford is investigating predicting driver behavior," said McGee. "This information can ultimately be used to optimize vehicle performance attributes such as fuel efficiency and driveability."
The Google Prediction API is one example of a technology that is helping Ford open doors to new predictive possibilities powered by the cloud.
"Ford already offers cloud-based services through Ford SYNC®, but those services thus far have been used for infotainment, navigation and real-time traffic purposes to empower the driver," said Johannes Kristinsson, system architect, Vehicle Controls Architecture and Algorithm Design, Ford Research and Innovation. "This technology has the potential to empower our vehicles to anticipate the driver's needs."
Work is now underway to study the feasibility of incorporating other variables such as driver style and habits into the optimization process so Ford can further optimize vehicle control systems, allowing car and driver to work together to maximize energy efficiency.
Integral to this next-step work is personal information security, an issue that is of the utmost importance to Ford. "We realize that the nature of this research includes the use of personal data and location awareness, something we are committed to protecting for our customers in everything we do," notes Kristinsson. "A key component of this project is looking at how to develop secure personal profiles that will ensure appropriate levels of protection and specific data use only by the driver and the vehicle to deliver the best driving experience.
"It's about pure customer benefit and creating individualized and optimized experiences – the right one for each person, vehicle and situation."
