NIRA Dynamics AB is a Swedish company focusing on research and development of signal processing and control systems for the automotive industry. It supplies automotive original equipment manufacturers (OEMs) and suppliers in Europe, North America, Latin America, and Asia with its products and systems. In January 2012, the number of vehicles equipped with NIRA's main product, TPI, exceeded the benchmark of 2,000,000.[1]


NIRA was founded in 2001 and is located at Mjärdevi Science Park in Linköping, Sweden.

During the early period, NIRA Dynamics developed the first two of its products: the anti-spin system NSC and a positioning system MAP.

NSC received the Volvo Technology Award and until 2004 was featured in the Volvo S40 and V40 models under the name DSA (Dynamic Stability Assistance).[2] Since 2007, NSC is in series production and featured in a line of motorcycles from one of the world leading motorcycle manufacturers.

In 2008, NIRA was presented the European Automotive Chassis Product of the Year Award by Frost & Sullivan for its product TPI.[3]

At present, NIRA has a next development being ready to become a product: the data logger with the prototype name T-Recs Box.

NIRA Dynamics holds an ISO 9001:2000 certificate stating that it has efficient and structured processes and tools to manage collaborative development projects in international environments.

Technology and products[edit]

NIRA Dynamics' core product is its Tire Pressure Indicator (TPI), an indirect tire-pressure monitoring system (TPMS) capable of detecting underinflation simultaneously in up to four tires. At the moment, TPI is installed in several Audi models (the A1, A3, A4, A5, A6, A7, A8, Q3, Q5, Q7, and TT); several Volkswagen models (Polo, Golf, Jetta, Beetle, Scirocco, Passat, Tiguan, Touran, and Sharan); several SEAT and Skoda models; as well as the Chery Arrizo 7 and the MG 3. The system meets the American FMVSS 138 and the European ECE R-64 regulations on tire pressure monitoring systems.[4] TPI is a software component that uses wheel vibration resonance measurement to estimate tire pressure from the signals of the wheel speed sensors that are part of the anti-lock braking system (ABS) and electronic stability control system (ESC). It is active after five minutes of calibration, after which it becomes self-learning. TPI does not require any in-wheel pressure sensors and RF (radio frequency) components. The Audi TT series was the first to be equipped with TPI, in 2006. The Audi A4 and A5 models followed the next year.[5] TPI can be fit into different electronic stability control hardware hosts, including those of Continental AG, Robert Bosch GmbH, and TRW Automotive.

NIRA Dynamics is developing sensor fusion based systems for different vehicle applications. Sensor fusion or sensor data fusion is the use of information from several different physical sensors to compute new virtual sensor signals. The virtual sensors can be of two different types: improved versions of physical sensor signals, or soft sensors that have no direct physical counterpart among the sensors used.

TPI Light is a product for vehicles with built-in anti-lock braking system (which is standard in most cars) but no electronic stability control system (which is not standard, particularly in emerging markets).
