Sabre Engineering awarded SBIR grant from the US Department of Defense.

For immediate release

February 2, 2004 

Sabre Engineering, Inc. today announced the Phase I award of a Department of Defense, Special Operations Command (USSOCOM) SBIR program entitled, “Development of a Family of Modular Light Tactical Wheeled Vehicles.”  The program’s objective is to develop a new core vehicle design concept that will support a multitude of tactical roles while being lighter in weight and readily adaptable both in manufacturing and in the field.  This new design will be air-transportable in the CV-22 Osprey while maintaining a high payload capacity.

This fast paced six month program builds on Sabre Engineering’s experience in the design and manufacture of specialty hybrid electrical vehicles and components.  This new design and accompanying manufacturing method will provide the Department of Defense a vehicle that is swift to produce in any quantity while providing a cost effective and adaptable platform for future combat roles.

“The fact that the US Department of Defense has awarded this grant is very gratifying and provides a clear indication of the importance that the military and SOCOM in particular are placing on new innovative vehicle designs and manufacturing methods,” said Robert W. Schmitz, Chief Executive Officer at Sabre Engineering, Inc.  “Sabre Engineering’s enabling technology is a real breakthrough for the design and manufacture of modular interchangeable components that will greatly reduce the logistical demands on the SOCOM fleet of combat vehicles.”

This project is an integral part of Sabre Engineering’s mission of providing vehicle systems and components that improve the function and reduce the operational cost of advanced hybrid electric vehicles from transit buses to highly specialized designs.  Its systems are currently used on vehicles that are transporting 55,000 passengers daily in 24x7 operations.

Sabre Engineering CEO Robert W. Schmitz - Interviewed on Live TV

Sabre Engineering's CEO, Robert W. Schmitz, was interviewed on Live TV by Denver KWGN Channel 2 News about the Denver 16th street mall shuttle buses.  As the one responsible for directing the engineering and design effort as well as being the author of the unique hybrid control system, Robert was interviewed live on the mall by news anchor Ms. Natalie Tysdal, where they discussed the design and operational efficiency of the worlds largest fleet of operating hybrid buses. 

These large (45') hybrid buses each pollute less than 1/60th that of a conventional diesel bus, while carrying twice the number of riders.  In other terms each bus carries 116 passengers while polluting less than a small car.  The technology developed for this achievement and specifically the advanced adaptive control system designed by Robert has been granted four US patents for its innovation.

The shuttle's design and operation has received numerous awards and accolades for its positive role in providing fast clean transportation on the 1.5 mile route that interconnects the primary bus and light rail routes inside Denver, with the hybrids transporting upwards of 55,000 riders each day in a seven day per week cycle.  The shuttles serve the open air 16th. street Mall route while providing a clean environment for businesses to operate downtown.

     Patent Abstracts    


US Patent 6,622,804 - September 23, 2003
Inventor: Schmitz, Robert W.,   et al.
Title: Hybrid electric vehicle and method of selectively operating the hybrid electric vehicle.

US Patent office published Abstract

A series type hybrid electric vehicle that controls an internal combustion engine, generator, and electric motor for reducing the load applied to the internal combustion engine when the internal combustion engine is restarted, lowers the thermal stresses to the internal combustion engine when the engine is turned off and is able to remove excess fuel when turning off the internal combustion engine.


US Patent 6,573,675 - June 3rd, 2003
Inventor: Schmitz, Robert W.,   et al.
Title: Method and apparatus for adaptive energy control of hybrid electric vehicle propulsion.

US Patent office published Abstract

A series type hybrid electric vehicle and method including a generator set having an internal combustion engine and a generator, a battery array and at least one electric motor includes a controller for controlling propulsion of the vehicle. The controller generates a second signal having a value proportional to the value of a first signal, indicative of user demand, and indicative of a demand of the at least one electric motor, determines if the value of the first signal is larger than the value of the second signal, increases the value of a command signal to the at least one electric motor, if the value of the first signal is not larger than the value of the second signal, and decreases the value of the command signal, if the value of the first signal is larger than the value of the second signal.


US Patent 6,483,198 - November 19, 2002
Inventor: Schmitz, Robert W.,   et al.
Title: Hybrid electric vehicle having a selective zero emission mode, and method of selectively operating the zero emission mode

US Patent office published Abstract

A series type hybrid electric vehicle that controls an internal combustion engine, generator, and electric motor for zero emissions within a zero emission zone. As the vehicle approaches the zero emission zone, the internal combustion engine and generator increase the electrical charge of the battery array to a predetermined level. The internal combustion engine and generator are eventually turned off to prevent emissions from entering the zero emission zone. As the vehicle leaves the zero emission zone, the internal combustion engine and generator are warmed to a predetermined level for a full capacity operation. When the internal combustion engine and generator reach the predetermined level, they operate at full capacity to bring the electrical charge of the battery array to a predetermined electrical level.


US Patent 6,333,620  - December 25, 2001
Inventor: Schmitz, Robert W.,   et al.
Title: Method and apparatus for adaptively controlling a state of charge of a battery array of a series type hybrid electric vehicle.

US Patent office published Abstract

A series type hybrid electric vehicle including a generator set having an internal combustion engine and a generator, a battery array and at least one electric motor includes a controller for maintaining a state of charge of the battery array within a control limit. A controller of the vehicle determines if the vehicle is in one of a plurality of forward driving modes, compares a state of charge of the battery array to an upper control limit associated with a forward driving mode, decreases generated by the generator, if the state of charge is equal to or greater than the associated upper control limit, and increases the power generated by the generator, if the state of charge is less than the associated upper control limit. A method of controlling the state of charge of the battery array includes determining if the vehicle is in one of a plurality of forward driving modes, comparing a state of charge of the battery array to an upper control limit associated with a forward driving mode, decreasing the power generated by the generator, if the state of charge is equal to or greater than the associated upper control limit, and increasing the power generated by the generator, if the state of charge is less than the associated upper control limit.
