Pirelli has invented a Tyre that can talk to your car
It’s not just new track-ready hypercars and bruising German super saloons that’ve made their debut at the 2018 Geneva Motor Show. Pirelli has a new tyre. In other news, Greggs has a new pasty.
We jest. Normally we wouldn’t bring you updates on new tyres, but we’ll make an exception for Pirelli’s ‘Cyber Car’ technology. You’ve heard of phones, thermostats and even entire cars connected to the Internet of Things. Soon, your tyre will be too, if Pirelli has anything to do with it.
The idea of the cyber car – more accurately the cyber tyre – is that each tyre contains a sensor that records not just internal pressure, like regular tyre pressure monitors, but temperature, vertical load, wear and location. Now, Pirelli already has a similar system called Connesso, which then relays this data back to the driver via a smartphone app. But the Cyber Car goes further by taking the human out of the equation and just talking directly to the car itself, and loading data to the cloud.
Why’s that useful? Well, for a start, the tyre can recognise when it’s cold, and likely to be slippery, and tell the car’s stability control and ABS to switch to a winter setting. Fine. But a car’s thermostat can do the same job. The tyre can go further, though. If it knows the vertical load going through it – and the pressure – it can work out the circumference of the tyre. This helps the car itself give a more accurate range indication – especially in electric cars, where the battery range can fluctuate wildly if tyres aren’t in good condition.
