ABSTRACT:
TECHNICAL FIELD
The present invention relates to powertrain testing systems which utilize shared memory to acquire data from and send data to nodes within a network in real time for the purpose of powertrain development.
BACKGROUND ART
Powertrain testing systems are well represented in the prior art. In the typical powertrain testing system, multiple test subsystems are employed to adjust powertrain operating setpoints, acquire powertrain performance data, and control test facility equipment. Typical subsystems in the test room include data acquisition, facility control, combustion analysis and a powertrain control module (PCM) interface.
Recent developments in powertrain testing require test site subsystem integration. Test site integration is typically achieved by providing Local Area Network (LAN) access. Standardized off-line data transfer protocols are used to transfer the data between network nodes over serial or ethernet based architectures. While industry standards have been developed for these architectures they do not support high speed, real-time and deterministic-type operation.
In addition, such off-line integration arrangements cannot effectively combine, time align, and process test facility data from various pieces of powertrain test subsystems. Thus, a need exists for a test-site integrated powertrain testing system capable of deterministic real-time data transfer for powertrain development.
SUMMARY OF THE INVENTION
Accordingly, it is an objective of the present invention to provide a system and method for powertrain testing by integrating all test site subsystems to communicate in real time.
In carrying out the above object and other objects and features of the present invention, a high speed real-time data acquisition computer network is utilized for powertrain testing. The computer network includes a plurality of computer nodes for monitoring and adjustably controlling the powertrain and applied load for acquiring data relating to powertrain performance. A shared memory is connected to the plurality of computer nodes for receiving in real time the data generated by each of the plurality of computer nodes. An integrating computer node is connected to the shared memory for receiving in real time data and is arranged to send different commands to the plurality of computer nodes as part of a powertrain testing process. The integrating computer node performs powertrain testing calculations to integrate in real time generated powertrain data.
The above objects, features and advantages of the present invention will be appreciated by one of ordinary skill in the art from the following detailed description of the best modes for carrying out the invention when taken in conjunction with the accompanying drawings.
