Allison’s New Controls Focus on Fuel Economy

Flexible, providing optimal shift strategies, the new controls are designed to adhere to varying OEM and operator requirements.

Allison Transmission announced today that their 5th Generation electronic controls are now available to all OEM customers.

The controls have been designed to match the new generation of global vehicle electrical-electronic architectures, Allison said, allowing for easy integration during the vehicle assembly process. The controls are flexible, providing optimal shift strategies while still adhering to varying OEM and operator requirements.

Enhanced programming and a new bump lever gear-selector design are new. Allsion engineers, the company said, focused on upgrading TCM hardware and software for faster, more precise processing capabilities.

There’s a new inclinometer embedded in the control module, which, the company explained, 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,” Allison said, “resulting in further reductions in fuel consumption.”

There are two additional acceleration levels, Allison said, that enhance Vehicle Acceleration Control (VAC) allowing for a greater ability to improve fuel economy by controlling engine fueling and moderating aggressive driving practices.
