The 2012 Virginia Tech Formula SAE car. learning how to use the torque telemetry system more effectively and build signal processing and drivetrain design/optimization algorithms around it,” said West. “The data acquired with the telemetry system will feed into our designs, shifting, drivetrain analysis, traction and launch control programs, and tuning of torque bias ratios in the differential. We’ll use that data to feed forward to the 2013 design, closing the loop between design, analysis, fabrication, and test.” In 2012, the VT Formula SAE team finished 12th overall in acceleration, 7th on the skid pad, 23rd overall in autocross. The team finished 43rd overall (out of 105), despite being black-flagged for a nonworking taillight (disabled by inadvertently toggling a software switch during a tuning of the automatic shifting control) in the endurance event. During the first 10 laps on the endurance course, the VT car used just 2 oz of fuel. “We look forward to doing better next year, thanks to better data to close the design loop,” said West.

The data collection system. are going through the drivetrain, and we can only do that through a torque telemetry system with a transmitter and full torsional bridge on one of the half-shafts,” said Collamer. “We have learned a lot about actual loads in our drivetrain, including the transitions associated with shifting and the torque profile for different events,” said West. “The Accumetrics telemetry system helps [us] see how the real-world measurements agree—or don’t agree—with our software simulations.” VT’s 2012 Formula SAE car now becomes a laboratory for the VT students. “The 2012 car will see a continuing extensive test program that involves
