New Generation Transmission Controls

Posted on January 31, 2013

Allison Transmission announced that its 5th Generation electronic controls for its transmissions are now available. The new controls have been designed to match the new generation of global vehicle electrical-electronic architectures and for easy integration during the vehicle assembly process. The new controls are designed to provide optimal shift strategies for productivity and efficiency, while still addressing varying OEM and operator requirements.

5th Generation controls incorporate enhanced programming and a new bump lever selector design. Allison said it also focused on upgrading transmission control module (TCM) hardware and software for faster, more precise processing capabilities. Embedded in the 5th Generation control module is a new inclinometer, which enhances vehicle productivity and efficiency in stop-start operations, the company said. 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, Allison said.

The new controls also provide two additional acceleration levels, enhancing Vehicle Acceleration Control (VAC), which Allison said allows for a greater ability to improve fuel economy by controlling engine fueling and moderating aggressive driving practices. Specific 5th Generation electronic controls features will be rolled out throughout 2013, the company said.
