Heavy-duty issues Top industry insiders provide their perspectives on critical issues such as sustainability, workforce development, and future growth at this year's Commercial Vehicle Engineering Congress and Exhibition. Autonomouse vehicles go off-highway Advances in sensors, CPUs, and software help in the druve to eliminate drivers. Power and precision Hydraulic motors and actuators evolve along two paths, both relying on advanced controls.

Top Technologies of 2009 The editors take a brief look back at the most significant innovations during the past year as voted on by readers. The big picture A holistic approach to hydraulics improves overall vehicle efficiency. Getting smart with electronics More chips, usually with more power and memory, are being deployed throughout off-highway equipment.

Software takes center stage Programs for hydraulics must combine reliability and flexibility. Technical Innovations Carraro launches concept variable transmission transaxle. Original Eqipment Case CE says new crawler dozer offers big performance, not weight.

For operators, a more quiet day at the office New materials that reduce weight and new strategies that control vibrations are finding their way into heavy equipment. The result is a bit more agility and efficiency.

Checking on safety As safety moves into the spotlight, many diagnostic techniques ensure that all the elements work reliably. Going green, quietly The emphasis on reduced emissions is not about to affect teh attention given to the desired levels of comfort and refinement in vehicles.

Metering hydraulic characteristics Multidimensional simulation is increasingly applied to the investigation of the fluid dynamics behavior of hydraulic components.

Applying emissions control strategies MTU Detroit Diesel comes clean about what it feels is its best path to Tier 4 Interim off-highway emissions compliance.

Still need steel? The use of ultra-high-strength steels is on the rise in a number of industries, including off-highway. But many alternatives are being considered, driven by the need of companies to be environmentally friendly.

Switching to new controls Hall-effect switches, LEDs transform cab interiors. Save the weight For efficiency improvements, the desire to reduce the mass of vehicle subsystems is far greater than the ability. As a result, off-highway suppliers must seek innovation and technological advances through other means.

Cleaner living A different approach to powertrain emissions testing is needed as the off-highway industry prepares to meet the challenges of forthcoming Tier 4 standards, both Interim and Final.

Clutch-application monitoring Fault monitors for off-highway equipment offer a means of minimizing the severity of transmission tie-ups.

What's wrong with me? Diagnostics systems provide more data to reduce downtime.

Developing next-generation biofuels Spurred by concerns over national security, future supplies of petroleum, and greenhouse gas emissions, many are looking for fuel from biological renewable sources. Control strategies take many paths I/O, EMC, and SIL are among the acronyms transforming controller development. Lean, green, and marine Following the lead set by road and air transportation, sea vessels are turning to increased amounts of composite materials in their construction.

The evolution of engineering via computer CAD has come a long way since the 1970s and '80s. Now with a price tag less that 10% of a 1980 system, CAD and its add-ons can tackle an ever-increasing range of tasks inculding automated engineering.

A good defense The latest military ground-vehicle navigation and communications give crews unprecedented situational awareness and on-the-move capability.

Lightweight, heavy-duty protection Next-generation military ground vehicles are being designed with materials that make them lighter for mobility while stronger to resist explosive impacts.
