Continental has revealed two new tyre technology concepts that will make for even greater road safety and comfort in the future.
The two systems enable continuous monitoring of the tyre’s condition, as well as situation-matched adaptation of tyre performance characteristics to prevailing road conditions. The technologies, called ContiSense and ContiAdapt, made their debut at the recent 2017 Frankfurt Motor Show (IAA).
ContiSense is based on the development of electrically conductive rubber compounds that enable electric signals to be sent from a sensor in the tyre to a receiver in the car. Rubber-based sensors continuously monitor both tread depth and temperature. If the measured values are above or below predefined limits, the system at once alerts the driver.
If anything penetrates the tread, a circuit in the tyre is closed, also triggering an immediate warning for the driver – faster than the systems used to date, which only warn the driver when the tyre pressure has already begun to fall.
In the future, the ContiSense system will feature additional sensors that can also be utilised individually. Thus, information about the road surface, such as its temperature or the presence of snow, can be “felt” by the tyre and passed on to the driver. The data can be transmitted to the vehicle electronics, or via Bluetooth to a smartphone.
ContiAdapt combines micro-compressors integrated into the wheel to adjust the tyre pressure with a variable-width rim. The system can thus modify the size of the contact patch, which under different road conditions is a decisive factor for both safety and comfort.
Four different combinations allow perfect adaptation to wet, uneven, slippery and normal conditions. For example, a smaller contact patch combined with high tyre pressure make for low rolling resistance and energy-efficient driving on smooth, dry roads. By contrast, the combination of a larger contact patch with lower tyre pressure delivers ideal grip on slippery roads.
The system also permits very low tyre pressures of below 1 bar to be set, to help ease the vehicle out of a parking space in deep snow, for example, or to traverse a dangerous stretch of black ice.
ContiSense and ContiAdapt are joined by a concept tyre that enables the benefits of both systems to be fully leveraged. The tyre design features three different tread zones for driving on wet, slippery or dry surfaces.
Depending on the tyre pressure and rim width, different tread zones are activated and the concept tyre adopts the required “footprint” in each case. In this way, the tyre characteristics adapt to the prevailing road conditions or driver preferences.
Continental considers both these tyre technology concepts promising solutions for the mobility of the future as tyres are adapted to meet the needs of automated driving and electrification.
Low rolling resistance, for example, makes it possible for electric cars to cover greater distances on a single charge. At the same time, the tyres can be adapted to suit the driver’s personal preferences, or in response to sudden changes in the weather.
These concepts are the logical next step in the future-oriented development of the REDI sensor, brought to market by Continental in 2014, which was instrumental in establishing smart communication between vehicle and tyre.
The new tyre technology concepts follow on from two established mobility technologies: ContiSeal, for the automatic sealing of punctures, and ContiSilent, for a tangible reduction in tyre/road noise.
Able to draw on more than a century of experience in tyre technology and with in-house expertise in the fields of vehicle electronics and automotive IT, Continental is systematically aligning its products with the future requirements of autonomous driving and electric mobility while bolstering its drive towards Vision Zero – an initiative that aimed at achieving zero fatalities, zero injuries and zero accidents.
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
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.)
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.
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.

LHI is coming to save your car from hazards
Local Hazard Information will give drivers advance warning of potential dangers lurking around the corner
There are many times when knowing what is around the corner could be useful. But for drivers that knowledge could be critical. Now, thanks to Ford’s new connected car technology, it is also a reality.
Local Hazard Information (LHI) marks a significant step on the journey towards a connected transport infrastructure by helping drivers prepare for and potentially avoid dangers on the road. When drivers ahead encounter sudden tailbacks, accidents or spilled loads, the driver behind – and possibly out of sight – is given advance warning. This could also apply to everything from freak hailstorms, to sudden flooding, or even landslides.
The triggers for the system come from what is happening in the cars ahead. It could be that airbags have been activated, hazard warning lights are flashing, or windscreen wipers are in operation. Previous traffic incident alert systems have relied on drivers to input information in order to generate alerts. LHI works autonomously, without the need for any driver interaction, to generate information and issue warnings.
Hazards are only displayed – via the dashboard display – if the incident is likely to impact on the driver’s journey. LHI is designed to be more beneficial to drivers than hazard information from current radio broadcasting systems, which often deliver notifications not relevant to them.
Already featuring as standard and free of charge for the first year on the new Ford Puma, LHI technology is being rolled out across more than 80 per cent of Ford’s passenger vehicle line-up by the end of this year. Crucially, the benefit will not be limited only to those travelling in Ford vehicles. Information sent can be used to alert drivers of other manufacturers’ vehicles, and vice-versa.
“What makes Local Hazard Information different is that it is the cars that are connected – via the Internet of Things. There is no reliance on third party apps. This is a significant step forward. Warnings are specific, relevant and tailored to try to help improve your specific journey.” Joerg Beyer, executive director, Engineering, Ford of Europe
How it works
Sensors monitor activities including emergency braking, fog lights and traction control to detect adverse weather or road conditions. Data from these activities is then computed to determine the hazard location and whether a traffic incident has occurred.
The vehicle automatically provides updates through a secure connection to “the cloud” using the Ford Pass Connect modem. Ford’s technology partner HERE Technologies operates the central cloud-based platform that collates information from multiple vehicle brands, governed by a business-to-business agreement.
The more cars are connected to the network, the greater the efficiency of the system. When many vehicles generate the same warning, others in the vicinity receive incident information from the cloud via the cellular network, enabling drivers to reduce speed or take appropriate action.
Additional information is sourced from public authority incident databases and traffic reports to provide drivers with further advance warnings including approaching vehicles driving on the wrong side of the carriageway, animals or people in the road ahead, and roadworks.
The on-board modem will be connected at the time of vehicle delivery. Customers may choose to opt in/opt out of certain data sharing.
