A Comprehensive Review of Electronically Controlled Implement Architectures for Mobile Machinery Using Secondary Control

Abstract

Transmission architectures for drive and implement functions in mobile machinery are currently diverting. On the one hand new market requirements, as alternative energy sources, impact the system design, and so do direct or indirect market drivers as efficiency, controllability, predictability, and driver comfort. On the other hand, the ability to electronically control components in alternative ways enable new architectures as well. The persons in charge of the machine design must find the balance between considering the new demands and relying on known building blocks to reduce risks and safeguard valuable resources. To help the decision making, an overview of new and promising architectures is presented, utilizing secondary control approaches for drive and work functions. These architectures target to recover kinetic energy, reduce throttling losses, and operate components in their sweet spot. Decisive criteria for the shown architectures are their maturity, degree of fulfilment of the market demands, minimized risk criteria via proven sub-components and feasibility of handling the transmission variants for varying market demands.
