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.

How cars can stop flu
The car of the future could help win the battle against superbugs – according to Jaguar Land Rover. Future models could help stop the spread of colds and flu thanks to innovative ultraviolet light technology (UV-C) borrowed from the medical industry, where it has been used for more than 70 years.
By integrating UV-C, Jaguar Land Rover believes it could help to stop bacteria and harmful viruses, known as pathogens, from surviving in the cabin. UV-C is currently widely used for disinfecting water, filtering air and sterilising surfaces by utilising wavelengths of light between 200 – 280 nanometres.
Exposing pathogens to UV-C within the air conditioning system breaks down the molecular structure of the DNA, neutralising them. Clean air is then released into the cabin. The technology could even help in the fight against drug-resistant superbugs.
Jaguar Land Rover is exploring UV-C technology as part of its vision to create a tranquil sanctuary inside each of its luxury vehicles. The manufacturer is piloting a wide range of driver and passenger wellbeing features, as it looks towards a self-driving future.
Dr Steve Iley, Jaguar Land Rover chief medical officer, said: “The average motorist spends as much as 300 hours per year behind the wheel. There is a clear opportunity to better utilise cars for administering preventative healthcare.”
“The implementation of individual wellbeing measures as part of our ‘tranquil sanctuary’ research promises to not only improve quality of life for our customers but in this case, offers clear advantages in reducing pathogen spread – protecting the overall population from the threat of disease; particularly as we move towards shared mobility solutions.”
Jaguar Land Rover is already actively seeking to neutralise pathogens in its latest generation Heating, Ventilation and Air Conditioning (HVAC) systems, available across the range including the all-electric Jaguar I-PACE and Range Rover Sport. The current Four-zone Climate Control and Cabin Air Ionisation system works by using high voltage to create trillions of nano-sized negatively charged particles (ions) coated in water molecules. These ions deactivate pathogens, forming larger particles which are removed from the air as they are brought back into the filter. As well as combatting pathogens, the ions also act upon odour molecules and allergens in a similar way.
Dr Iley said: “In the colder months infections are spread more easily, it’s reassuring to know that in your car at least, you can be confident that harmful pathogens are being neutralised.”
Recent medical trials* suggest the use of UV-C could be even more effective as it has been shown to cut the transmission of four major superbugs by up to 30%. Researchers focused on four drug-resistant organisms: MRSA, vancomycin-resistant enterococci (VRE), C. difficile and Acinetobacter.
Immunology expert, Dr. Hellmut Münch, CEO at Medical Enzyme Research Association, said: “The rise of superbugs and allergens is one of the largest threats we face as a species today. Investment in immunology is vital in ensuring that our immune systems stay ahead of the race against microorganisms, which are evolving far quicker than traditional pharmaceuticals can keep pace with. It is important that we continue to take an innovative look at how we can adapt our environment to help prevent the spread of the most harmful pathogens – which is why this research is paramount.”
