Mercedes-Benz may have branded the Smart Car, but Ford is trying hard to lay its own claim to that title.

The US automaker is announcing an energy-efficiency feature for its plug-in vehicles where the vehicle's GPS system helps it "learn" common routes, and ways to save fuel.

Called EV+, Ford's new feature combines the GPS data with certain algorithms to program powertrains to use its limited electric power most appropriately. For instance, the closer the vehicle is to a frequent destination, the more the vehicle is directed to operate in electric-only mode. In other words, if you're about to arrive home and there's juice in the pack, the car shifts into electric mode. The patent-pending feature is available on Ford's Fusion and C-Max hybrids as well as its C-Max Energi and Fusion Energi plug-in hybrids. Check out Ford's press release below.

Ford must be hoping advancements like this more than compensate for what Plug In Cars notes are some design shortcomings when it comes to storage capacity for the automaker's new plug-in vehicles. The C-Max gives up about 20 percent of its storage space (compared to the hybrid version) and the Focus Electric EV's storage space is a whopping 40 percent less than the conventional Focus.

Last month, Ford more than doubled it's October 2011 alt-fuel sales, selling a monthly-record of 118 Focus Electrics and recording its first sales of the C-Max Energi PHEV.

Ford Hybrid's EV+ Feature Learns and Automatically Adjusts Powertrain to Deliver More Electric-Only Driving

Patent-pending EV+ allows vehicles to learn frequent destinations and as a result, changes the way power is used in vehicles such as C-MAX Energi plug-in hybrid and Fusion Hybrid
Leveraging GPS data from Ford SYNC®, Ford engineers developed a proprietary, predictive software algorithm that automatically adjusts powertrain controls based on location to deliver more electric-only driving
New Ford innovations have led to a 50-fold increase in hybrid patents to nearly 500, which have helped the automaker's lineup of electrified vehicles set benchmarks in areas such as fuel economy, performance and range

DEARBORN, Mich., Nov. 8, 2012 – Ford is taking the smarts and performance of its electrified vehicle lineup to a whole new level with EV+, a patent-pending feature that actually helps vehicles learn frequent destinations, and delivers to hybrid drivers what they love – more driving time in electric-only mode.

EV+ is part of SmartGauge® and is a standard feature on the Ford plug-in hybrids, C-MAX Energi and Fusion Energi, along with the hybrid versions of Fusion and C-MAX.

"We know from our research that hybrid drivers want to drive as often as they can in electric-only mode, especially near their home or frequently visited locations," said Kevin Layden, Ford director of Electrification Programs and Engineering. "EV+ not only delivers that capability, but also demonstrates how Ford puts customer needs and wants above everything else."

EV+ combines the built-in GPS of Ford SYNC® with proprietary software algorithms developed by Ford engineers to learn frequent destinations.

Once frequent destinations have been learned – such as your home parking location – EV+ adjusts how the electric power stored in the vehicle's high-voltage battery is used to power the vehicle. If EV+ determines the vehicle is nearing a frequent destination, it has the capability to remain in electric-only mode.

"We already have a GPS unit in every Ford with SYNC, so really it was just a matter of tapping into that the right way," said Layden. "This is one of the first examples of how we're looking to make the car smarter, by leveraging on board data to provide features and services that add value to the driving experience."

EV+ joins a growing list of roughly 500 hybrid-specific patents Ford has accumulated in the last 20 years. Patents include everything from the leaves on the cluster screen of SmartGauge and the hands-free liftgate of the C-MAX Hybrid and C-MAX Energi to an available EV-only mode button that allows customers to access electric power on-demand.

Enhancing performance
EV+ was developed by two Ford employees: Ken Frederick, HEV powertrain calibration engineer, and Matt Smith, product design engineer. They are the authors of the patent application that was recently published by the U.S. Patent & Trademark Office.

When engaged, EV+ uses onboard GPS equipment and predictive software algorithms written by Frederick and Smith to learn the latitude and longitude of a vehicle and identify locations that are visited on a frequent basis, such as home and work. The feature can be disabled and the data erased at the push of a button.

When the feature identifies frequent destinations, the way electric power is used changes. Specifically, when within a radius of 1/8 mile, or 200 meters, of a frequent stop, the vehicle has increased capability to stay in electric-only mode, the internal combustion engine stays off, and an "EV+" light appears on the dashboard.

"One of Ford's biggest strengths is the quality of our controls and calibration. We do all of that work in-house and it shows when we deliver a feature like EV+," said Rob Iorio, Ford Electrified Propulsion Systems Manager. "No other automaker seamlessly integrates global positioning and propulsion system control as we have with EV+."

Big data, big challenge
Originally, the plan was to develop a way for vehicles to collect and digest vast amounts of information to predict and adjust to different driving demands.

"We wanted a vehicle to perform in a certain way when it hit a certain spot," said Smith.

The team quickly discovered that collecting and analyzing the vast amounts of data needed to make such predictions would require an immense hardware and software system – one that would demand too many resources, both in terms of initial development and inside each vehicle.

A breakthrough came, say Smith and Frederick, when they developed a way to reach their goal without the need to collect and store droves of information. Instead, their answer was to engineer a way to analyze incoming GPS information and control distribution of a vehicle's power based on those data.

"We realized that harnessing data already available was the way we could achieve our goal of improving the entire hybrid vehicle driving experience," said Frederick. "Once we had access to the data, we applied machine learning principles to predict frequently visited locations that would determine what powertrain controls should be applied to achieve our goal."

Every new Ford with SYNC has GPS equipment built into the SYNCmodule.

Ford's award-winning SYNC communications and entertainment system enables voice-activated communication through a driver's mobile phone and interaction with the car's audio system. Among its many features and options, SYNC provides location-based services, such as turn-by-turn directions, and now shares GPS coordinates with EV+.

Additionally, SYNC uses GPS to relay information about vehicle location to emergency personnel in the event of an accident through 911 Assist® when the feature is properly activated.

      It should use the GPS navigation to provide "eco" routes that are less hilly or where average speeds are lower but the route is shorter.

        It actually does that already. You can select Fastest Route, Shortest Distance, and Eco Route :)

      i knew about what empty means in a HEV battery pack, but I didn't think about the engine warm up phase, that's a good point. Still, this is a much more important feature in a PHEV where you've got many kWhs of gas that you can displace by filling up on electrons from the grid.

      Will it use the built in GPS navigation system? The maps in my 11 month old Ford S-Max are already somewhat outdated, and updating it is very expensive. Moreover, it has no live traffic information like my TomTom has. It does use traffic info received via FM radio signals (TMC, common in Europe), but that is for the highways / autobahn only and not the local roads. As a consequence, I hardly use the built in sat-nav. Would be great if they adress these issues in one go; trying to save fuel while missing a new highway exit misses the point.

        That's the problem with any built in nav system.

          I think it depends on how much you spend on the car... The nav system in the Model S looks amazing.

          @fefifofum Tesla uses Google Maps pulling from a cellular data connection, so no, there is no updating involved.

          I'm sure the Tesla requires updates just like the Ford.

      I don't understand why you'd want this in a non-plug-in hybrid. Arriving at home with an empty pack in a PHEV means you burned as little gas as possible, giving you the chance to fill up on the plug. Arriving at home with an empty pack in an HEV just means your engine will have to make up for it next time it starts up, and if anything, might lead to quicker aging of the battery if it hangs out at a lowish SOC for too much of the time.

        An "empty" pack in a Prius isn't technically empty. I believe the SOC is at something like 40% when the gauge says empty. But it makes sense to use up as much battery as possible during the trip because the engine will have to come on anyways when the car starts back up to bring it back to proper operating temperature. Better to have it charging the battery and warming up than just having it warm up and do nothing else.

        Yes, this should be more an Energi feature, the hybrid with a plug.
