The vibrations which are applied on the driver during car ride can be source of low ride comfort. The vibrations can (in dependency on their intensity, frequency and duration) decrease driver attention, can be source of driver's fatigue, or even can be source of various diseases (especially backbone diseases). Seating is therefore designed with regard to lowering of such a negative vibrations. There are developed methods of measurement of ride comfort, for comparing of vibrations effects on different seats. The ride comfort is measured with 3 axial digital MEMS accelerometers. An accelerator sensor should be positioned in the center of seat, beneath the hip joints of driver. The driver should sit on the seat by the standard way. For the real-time measurement the cRIO platform of National Instruments (Austin, Texas, USA) is used. The cRIO consist of two parts, the RT (Real-Time) controller (NI cRIO 9014) and the box (NI cRIO 9104). The box is programmed by FPGA (Field Programmable Gate Array).
