Table 5 also lists the sensor system which provided each signal, shown in Fig. 19 through Fig. 22. The weather station (Fig. 21) was not tested in a wind tunnel to determine accuracy when used in non-static applications. Fig. 19. VBOX II Lite 26 Fig. 20. Air-Weigh Scale

J1939 Vehicle Data Bus Connector The SoMat eDAQ-lite data acquisition system shown in Fig. 23 was used to capture data from the sensors called out in Section 2.3.2. 2.3.5 Test Vehicles Fig. 23. SoMat EDAQ-lite DAS Schrader provided access to six 2005 Volvo VNL tractors, along with ten trailers <strong>for</strong> use in the FOT. These vehicles were instrumented with the DAS and sensor suite, and then continued in their normal vocational operations. A typical Schrader truck used in the FOT is shown in Fig. 24. 27
