SwRI Information

Home

Southwest Research Institute (SwRI) motorcycle technology engineers develop robust engine control systems that balance the often conflicting requirements of performance, fuel economy, and emissions.

SwRI has developed a full-authority engine controller, composed of industry proven components, that provides:

• Real-time, model-based control

• Diagnostic functions

• Classic control

• Adaptive learn algorithms

• Advanced signal processing

• 700-MHz PC with real-time (QNX)

• 1-million gate Xilinx FPGA for engine synchronicity and output control

• 16-channel analog input card 6-channel analog output card

• Graphical display and control via a Linux laptop

Customization is available to add more analog and digital inputs and outputs, custom control algorithms, high-speed digital processing, CAN communications, and high-speed data acquisition.

On-Vehicle Data Acquisition

SwRI engineers use advanced on-vehicle data acquisition systems to assist in the testing, development, and analysis of motorcycles. Each system is designed with the most advanced technology in acquisition hardware and software platforms and allows high speed data sampling of all pertinent on-road data, including:

• Suspension travel

• Suspension rates

• Vibration of multiple body components

• Noise 

• Vehicle Speed, acceleration, and braking performance

• Multiple intake, exhaust, engine and transmission temperatures

• Exhaust pressures

• Intake pressures

• Clutch and shifter force

• Brake forces and temperatures

• Lean angle

• Throttle position

• Fuel flow

• Combustion analysis

• Cylinder pressure

• Peak pressure and location

• Location of peak pressure

• Heat release

• Ignition delay

At SwRI, we are always striving to offer the best services possible to our clients. This motorcycle technology information represents only a small portion of how SwRI can assist your company with motorcycle testing, research, and development. For a more comprehensive review of our capabilities, please contact Charles Roberts, Ph.D., at croberts@swri.org or (210) 522-5521 to arrange a tour of our complete facilities. We look forward to seeing you in San Antonio.
