 Powertrain Controls
SwRI’s Powertrain Controls Section excels in the
areas of powertrain and vehicle controls and supports the automotive industry in
a broad range of efforts including real-time modeling for diesel, gasoline and
natural gas engines and control of combustion and exhaust treatment systems.
Capabilities of the staff include full-authority control and limited-authority
control; on-board diagnostics; control of automated manual transmission; control
of electric, hydraulic and fuel cell hybrid powertrains; and design and
production of custom electronic hardware. SwRI’s experienced technical staff
have developed solutions for a number of complicated and challenging problems
including meeting 2010 heavy-duty emission standard with minimal engine-out NOx;
meeting OBD-II regulation for light-duty diesel passenger vehicle; achieving
seamless transient operation of engines with multiple combustion modes; and
achieving high-speed and safe autonomous vehicle operation. SwRI's powertrain
control systems expertise has also been put to work in the area of high volume
production powertrain electronic control unit (ECU) design, development, and
testing.
Powerful and cost effective rapid prototyping systems
(SwRI's RPECS, or commercially available dSPACE, LabVIEW, openECU etc.) are used
for applications ranging from single-cylinder engine control through integrated
hybrid vehicle control. Rapid prototyping control has been successfully applied,
for example, to demonstrate U.S. Tier-II Bin-5 compliant diesel vehicle using
alternative combustion and a 4-way catalyst; to control a free-piston engine in
four-stroke mode; and to control advanced combustion concept engines (gasoline
and diesel) in demonstration vehicles.
