At last, cars talk to traffic lights to catch ‘green wave’

Published

Stop-and-go traffic in cities is annoying. By contrast, we are pleased when we have a “green wave” – but we catch them far too seldom, unfortunately. With the Traffic Light Information function, drivers are more in control. They drive more efficiently and are more relaxed because they know 250 meters ahead of a traffic light whether they will catch it on green. In the future, anonymized data from our cars can help to switch traffic lights in cities to better phases and to optimise the traffic flow.

In the USA, Audi customers have been using the “Time-to-Green” function for two years: if the driver will reach the lights on red, a countdown in the Audi virtual cockpit or head-up display counts the seconds to the next green phase. This service is now available at more than 5,000 intersections in the USA, for example in cities like Denver, Houston, Las Vegas, Los Angeles, Portland and Washington D.C. In the US capital alone, about 1,000 intersections are linked to the Traffic Light Information function.

Since February, Audi has offered a further function in North America. The purpose of this is especially to enable driving on the “green wave”. “Green Light Optimized Speed Advisory” (GLOSA) shows to the driver in the ideal speed for reaching the next traffic light on green.

Both Time-to-Green and GLOSA will be activated for the start of operation in Ingolstadt in selected Audi models. These include all Audi e-tron models and the A4, A6, A7, A8, Q3, Q7 and Q8 to be produced from mid-July (“model year 2020”). The prerequisite is the “Audi connect Navigation & Infotainment” package and the optional “camera-based traffic sign recognition”.

Why is this function becoming available in Europe two years later than in the USA? 

The challenges for the serial introduction of the service are much greater here than, for example, in the USA, where urban traffic light systems were planned over a large area and uniformly. In Europe, by contrast, the traffic infrastructure has developed more locally and decentrally – with a great variety of traffic technology. How quickly other cities are connected to this technology depends above all on whether data standards and interfaces get established and cities digitalise their traffic lights.

On this project, Audi is working with Traffic Technology Services (TTS). TTS prepares the raw data from city traffic management centres and transmits them to the Audi servers. From here, the information reaches the car via a fast Internet connection.

Audi is working to offer Traffic Light Information in further cities in Germany, Europe, Canada and the USA in the coming years. In the large east Chinese city of Wuxi, Audi and partners are testing networks between cars and traffic light systems in the context of a development project.

In future, Audi customers may be able to benefit from additional functions, for example when “green waves” are incorporated into the ideal route planning. It is also conceivable that Audi e-tron models, when cruising up to a red traffic light, will make increased used of braking energy in order to charge their batteries. Coupled with predictive adaptive cruise control (pACC), the cars could even brake automatically at red lights.

In the long term, urban traffic will benefit. When cars send anonymised data to the city, for example, traffic signals could operate more flexibly. Every driver knows the following situation: in the evening you wait at a red light – while no other car is to be seen far and wide. Networked traffic lights would then react according to demand. Drivers of other automotive brands will also profit from the development work that Audi is carrying out with Traffic Light Information – good news for cities, which are dependent on the anonymised data of large fleets to achieve the most efficient traffic management.

In future, V2I technologies like Traffic Light Information will facilitate automated driving. 

A city is one of the most complex environments for an autonomous car. Nevertheless, the vehicle has to be able to handle the situation, even in rain and snow. Data exchange with the traffic infrastructure can be highly relevant here.

Car buyers to start abandoning fuel-power by 2025

Car buyers in the United States and Europe expect electric vehicles to become a viable alternative to fuel-powered cars in the next five years.

Published

A new report outlining consumer expectations of battery electric vehicles (BEVs) and their viability as replacements for traditional fuel-powered cars or internal combustion engine (ICE) vehicles suggests a massive shift beginning in 2025.

The conclusion emerges from a report by human behaviour and analytics firm Escalent, entitled The Future of BEV: How to Capture the Hearts and Minds of Consumers. It reveals the intent of many consumers in the United States and Europe to abandon ICE vehicles altogether, citing the improved infrastructure and range of BEVs.

The Future of BEV gives auto and mobility manufacturers a strategic view of the benefits of their products in the eyes of consumers and highlights the areas of opportunity for automakers to push the innovation boundaries of BEVs to spur broad adoption of the technology.

“While most buyers don’t plan to choose BEVs over gasoline-powered cars within the next five years, consumers have told us there is a clear intention to take BEVs seriously in the five years that follow,” says Mark Carpenter, joint managing director of Escalent’s UK office. “However, manufacturers will need to tap into the emotional value of BEVs rather than just the rational and functional aspects to seize on that intent and inspire broader consumer adoption.”

The study demonstrates a significant shift in consumers’ expectations that BEVs will become viable alternatives to—and competitors with—ICE vehicles over the coming decade. Though 70% of Americans plan to buy a gasoline-powered car within the next year, just 37% expect to make that same purchase in five to ten years. Similarly, while 50% of European consumers favour buying vehicles powered by gasoline and diesel in the near-term, that figure drops to just 23% in five to ten years.

At the same time, consumers on both sides of the Atlantic see BEV adoption rising to 36% in Europe and 16% in the US, with respondents also indicating intent to purchase hybrids and hydrogen-powered cars.

Infrastructure clearly continues to be one of the biggest barriers to adoption. While some work is being done in Europe as well as in the US, the data show there is a significant need for some players to take ownership if manufacturers want to move the needle on BEV adoption.

US and European consumers have stark differences in opinion as to which entities they believe are primarily responsible for providing BEV charging stations. American consumers consider carmakers (45%) the primary party responsible, followed by fuel companies, local government/transport authorities, and the national government in fourth. On the other hand, European consumers view the national government (29%) as the primary party responsible for providing BEV infrastructure, followed by carmakers, local government/transport authorities and fuel companies.

Mercedes brings older models to the connected world

The Mercedes Me Adapter is designed to bring older Mercedes Benz models into the connected world, allowing one to keep a close eye on the car via a smartphone. SEAN BACHER installs a unit

Published

on

In this day and age, just about any device, from speakers to TVs to alarm systems, can be connected and controlled via a smartphone.

In keeping with this trend, Daimler Chrysler has launched a Mercedes Me Adapter – a system designed to connect your car to your phone.

The Mercedes Me Adapter comprises a hardware and software component. The hardware is an adapter that is no bigger than a match box and plugs into the OBD2 diagnostics socket under the car’s steering wheel column. 

The software component is the Mercedes Me app, which can be downloaded for Android and iOS devices. (See downloading instructions at the end of the review.)

Setting up

Before you can start using the Mercedes Me Adapter, you need to download the app and begin the registration process. This includes setting up an account, inputting the vehicle’s VIN number, the year it was manufactured and the model name – among many other details. This information is sent to Daimler Chrysler. It is advisable to get this done before heading off to Mercedes to have the adapter installed, as it takes quite some time getting all the details in.

The next step is locating your nearest Merc dealer to get the adapter installed. You have to produce the registration papers and a copy of your ID – something Mercedes neglects to mention on its website, or anywhere else, for that matter.

What it does

The Mercedes Me Adapter is designed to show the car’s vital statistics on your mobile device. On the home screen, information like parking time, odometer reading and fuel level is displayed.

Below that is information about your most recent journeys, such as the distance, time taken, departure address and destination address. Your driving style is also indicated in percentage – taking into account acceleration, braking and coasting.

A Start Cockpit button displayed on the home screen includes a range of widgets offering additional information, including where your car is parked – right down to the address – as well as battery voltage, total driving time, distance and driver score since the adapter was installed. A variety of other widgets can be added to the screen, allowing for complete customisation.

Many users have have pointed out that that there is no real point to the adapter. However it does offer benefits. Firstly, your trips can be organised into personal and business categories and then exported into a spreadsheet for tax purposes. Secondly, you can keep a very close eye on your fuel consumption, as it automatically measures how many litres you put in each time you visit the garage and the cost (the cost per litre must be entered manually so it can work out total refuelling costs). This is also quite beneficial in terms of working out how much fuel you go through, without keeping all the pesky slips when it comes to claiming at the end of the month.

Probably the most important benefit is that it monitors the engine, electrical, transmission and gearbox, sending notifications as soon as any faults are detected. A perfect example was encountered on a recent trip I made to Pretoria. Upon arriving, I received a notification that I needed to check my engine, with the Mercedes roadside assist number blinking and ready for me to dial.

The notification did not even show up on the actual fault detection system, except for the faint glow of the orange engine light, which I would never have noticed in the bright light. I immediately took it Mercedes and they diagnosed it as an intermittent thermostat error, which they said is fine for now but that I have to keep an eye on the engine temperature.

Conclusion

The convenience of easily being able to export mileage for tax purposes and refuelling stops as well as being able to locate your car at anytime should be more than enough to qualify it as a pretty useful companion for your car.

Add to this the fact that it is completely free from Mercedes, and that makes it an absolute no-brainer. Should you not like it, simply unplug the adapter and uninstall the app. The only thing lost is half an hour while the Mercedes technician sets it up, ensures it is working and gives you a crash course on how to operate the app.

The adapter will only work in Mercedes Benz models from 2002 onwards. No warranties are lost, as the adapter does not increase the car’s performance and is a genuine Mercedes part.

2017 models and above do not need the adapter as everything is installed when the car is manufactured. All one needs to do is install the app and pair it with the car.
