Vehicles with wrong tire pressure cause accidents and consume excess energy. Tire Pressure Monitoring Systems (TPMS) were developed to prevent these issues. The first passenger vehicle to adopt tire-pressure monitoring was the Porsche 959 in 1986 and today it is becoming a legal requirement in more and more countries. Car manufacturers have been introducing different TPNS systems more or less voluntarily but in the United States, as of 2008 and the European Union, as of 2012, all new passenger car models released must be equipped with a TPMS. Similar laws are on their way in Asia-Pacific.
Inspiring examples: Tire Pressure Monitoring Systems – TPMS
TPMS are definitely complex from an engineering, communication and product point of view and the combined investment, including equipment in garages and motor vehicle inspection sites, the sensors in the tires and the receiving part of the in-car system is very big. The National Highway Traffic Safety Administration (NHTSA) in the US estimates that 660 fatalities and 33,000 injuries each year are attributable to crashes caused by underinflated tires (Bob Ulrich, Editor, at Modern Tire Dealer) so it seems like well working TPMS can help save lives, money and the planet. But every system like this is always a potential hacker target and Rutgers University and the University of South Carolina released a joint study some years ago indicating that they had succeeded to hack a car through the TPMS.
In any case, this is a typical M2M application – it’s been around for years, many of us have them, they are not SIM-based and they deliver on the three M2M promises: safety, sustainability and efficiency.
