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 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 and reduce the system cost. 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
- Soft sensors that have no direct physical counterpart among the sensors used.
In both cases sensor fusion adds value not cost.
Vehicle Applications
Below an illustration of how the sensor fusion ideas may be applied to vehicles. To the left we have different types of sensors available in a modern high-end car: 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, may be used as inputs to various control systems, such as anti-spin systems and adaptive cruise control systems, or in some Human/Machine Interface (HMI), for example a display on the dashboard. Another important feature of a sensor fusion based solution is the increased possibilities to detect and isolate faulty sensors and to reconfigure the system to achieve “limp home” functionality.
