allow <strong>for</strong> sustained testing such as that which will be required in the Field Testing. Interior runs<br />

will not interfere with cargo movement or be susceptible to damage from cargo or loading<br />

machinery. Exterior runs will be protected from the environment and damage from impact and<br />

tractor articulation. An external enclosed raceway (conduit) is expected to be the best method.<br />

Cabling will pass to and from the conduit via protrusions in the side of the trailer.<br />

Tractor cable runs to and from sensors will be routed in a manner to allow <strong>for</strong> sustained testing<br />

and occupant safety. Consideration will be given to shielding these cables from engine/exhaust<br />

heat and damage from objects thrown from the roadway. Cable runs will have<br />

termination/inspection points to allow <strong>for</strong> trouble shooting without cable removal.<br />

The DAS will be shock mounted in the tractor cab using vehicle vibration dampening mounts or<br />

equivalent.<br />

3.6 Sensor/DAS Verification and Calibration<br />

All sensors, cabling, and the DAS will be verified <strong>for</strong> operation and calibrated after the initial<br />

integration. This verification (pre-Pilot Testing) will take place at the Eaton Proving Grounds in<br />

Marshall, MI.<br />

4.0 PILOT TEST<br />

Pilot Testing will take place over a three-month period and will involve testing the instrumented<br />

tractor-trailer in a loaded condition. Various routes will be driven to collect data similar to what<br />

will be required in the Field Test.<br />

4.1 HVDC Daily Log Sheet<br />

Each day, during the pre-trip inspection, the Test Engineer will initial an HVDC Daily Log Sheet<br />

(Figure 4.1). The names of the driver and Test Engineer will be recorded along with the day’s<br />

date. Tire pressure <strong>for</strong> each tire will be also be recorded (see Section 4.3) prior to driving.<br />

During the days driving, fuel purchase and mileage at fuel purchase will be recorded along with<br />

vehicle weight (be<strong>for</strong>e and after fueling). If desired the driver can list his “miles driven per<br />

state” to fulfill his logbook requirement. Additionally, the Test Engineer can use the HVDC<br />

Daily Log Sheet as a Checklist <strong>for</strong> daily and periodic events.<br />
