Allison Transmission unveils 5th generation electronic transmission controls

Updated Jan 23, 2013

Allison Transmission has introduced its 5th Generation Electronic Controls, which the company says emphasize enhanced fuel economy.

This latest generation of electronic controls includes upgraded Transmission Control Module (TCM) hardware and software and a new integral inclinometer, among many other features, which Allison says will deliver enhanced fuel economy and vehicle performance with easy OEM integration. These improvements have been designed to match the new generation of global vehicle electrical-electronic architectures and for easy integration during the vehicle assembly process. The result, Allison says, are electronic controls that are flexible, while providing optimal shift strategies for industry-leading productivity and efficiency, while still addressing varying OEM and operator requirements.

The company says the 5th Generation controls feature enhanced programming and a brand new bump lever selector design. Allison engineers also focused on upgrading TCM hardware and software for faster, more precise processing capabilities.

Embedded in the 5th Generation control module is a new inclinometer, which Allison says enhances vehicle productivity and efficiency in stop-start operations. The inclinometer’s precision and responsiveness improve Load Based Shift Scheduling (LBSS) performance as the automatic selection between economy and performance shift schedules is faster and more accurate, resulting in further reductions in fuel consumption. Additionally, this new generation of electronic controls provides two additional acceleration levels, enhancing Vehicle Acceleration Control (VAC) to allow for an even greater ability to improve fuel economy by controlling engine fueling and moderating aggressive driving practices.

“The combination of Allison Transmission’s Continuous Power Technology and the latest 5th Generation electronic controls is the best way to provide our customers with enhanced fuel economy as well as improved vehicle performance, fleet productivity and efficiency ,” said Steve Spurlin, Executive Director of Application Engineering and Vehicle Integration for Allison Transmission.

Specific 5th Generation electronic controls features will be rolled out throughout 2013.
