Home About Products Career Contact News Downloads A Swedish expert company focusing on innovative software solutions for vehicles NIRA Dynamics was founded in 2001 and is located in Mjärdevi Science Park in Linköping, Sweden, from where we support customers and partners worldwide. Technology NIRA Dynamics is developing unique sensor fusion based systems for different vehicle applications that utilize the potential in the sensor fusion idea to improve the performance, reduce the system cost and at the same time, increase the customer value. Through close collaborations with world-class research groups at Linköpings universitet, Sweden, and Chalmers University of Technology, Sweden, NIRA Dynamics is constantly in touch with the research frontier in these and other areas where sensor fusion and other types of signal processing are employed. Sensor Fusion Sensor fusion, or sensor data fusion, can be described as using information from several different physical sensors to compute new, virtual sensor signals. The virtual sensors can in principle be of two different types: Improved versions of physical sensor signals, or So-called ‘soft sensors’ or virtual sensors that have no direct physical counterpart. In both cases sensor fusion adds value, not cost. Vehicle Applications The illustration at the bottom of the page shows how the sensor fusion idea is applied to vehicles. To the left we have typical examples of different types of sensors available in modern passenger cars: Wheel speed sensors (ABS), yaw and/or roll rate gyros, accelerometers, GPS, and various engine (and powertrain) related signals. These signals are fed into a sensor integration unit, which merges the information from the different sensors and allows the computation of the virtual sensor signals. These, in turn, are used as inputs to various control systems, such as ESC and adaptive cruise control systems, or in a Human/Machine Interface (HMI), for example a display on the dashboard. Another important feature of a sensor fusion based solution is the increased ability to detect and isolate faulty sensors and to reconfigure the system to ensure at least a “limp home” functionality.
