Development of a Vehicle Drive Shaft Telemetry System 2016-01-0410

Historically, driveshaft torque data has been obtained using slip rings. Slip rings, however, are expensive, and require time-intensive driveshaft modifications for proper installation. In addition, the time and expense involved in field servicing units is prohibitive. For these reasons, AISIN Technical Center of America (ATCA) investigated a viable telemetry solution. At the onset of this development activity, existing torque telemetry solutions had their own issues. In particular, they did not offer the same data resolution as slip rings, they lacked sufficient battery life for long-term, real-world testing applications, and they suffered from data drop-outs. ATCA worked with TECAT Performance Systems to develop a torque telemetry solution that addressed all of these issues. This paper presents the development activity involved, alongside real-world measurement data showing the results of both the slip ring and telemetry solutions.
