    Some of the research problems pertaining to cyclic combustion variability are reformulated from a perspective markedly different from the fluid dynamic and thermodynamic models which traditionally characterize this research: a system viewpoint is embraced to construct a stochastic model for the cylinder pressure process and the dynamics of the internal combustion engine. A deterministic model for ... View full abstract»

    A digital simulator for an automotive multiplexing system has been developed and tested. The basic architecture and logical flow and block diagrams are described. Some results of the simulation are given. The contention scheme was found to work successfully in the simulator, and the outputs were found to be ordered in the same manner as expected by the requirements of the protocol. The network tra...

    A contribution is made to the task of constructing a global model for the IC (internal combustion) engine. A robust submodel is formulated for the dynamics of the IC engine, where-in the engine is viewed as a system with input given by cylinder pressure and output corresponding to crankshaft angular acceleration and crankshaft torque. The formulation is well suited to closed-loop engine control an... View full abstract»

  • A beacon navigation method for autonomous vehicles

    Publication Year: 1989, Page(s):132 - 139

    A method for navigating autonomous vehicles is presented. Based on the three-point problem from land surveying, this navigational technique makes use of angular measurements between fixed beacon pairs. Extremely accurate position information can be obtained over a large area with simple trigonometric or analytic geometry calculations. Typical worst-case errors are of the order of 10 cm throughout ... View full abstract»

  • Magnetostrictive torque sensor performance-nonlinear analysis

    Publication Year: 1989, Page(s):159 - 167

    The effects on performance of magnetostrictive torque sensors due to nonlinear properties of magnetic materials are analyzed. A solution for the nonlinear problem is described. For constant magnetomotive force (constant current) excitation, nonlinear effects dramatically reduce the predicted output signal of the sensor from that computed using linear models. Saturation and the subsequent fall-off ... View full abstract»

    A forward-looking, relatively inexpensive, onboard automotive radar called cradar, that senses the highway environment of the vehicle is described. The radar measures the range, range rate, and bearing angle of roadway targets. The radar has a proposed angular spread of approximately 17° and a range of 5-100 m. It uses a unique front end, designed to provide maximum information from a single s... View full abstract»

    An efficient method of sensor diagnosis in electronically controlled IC engines is demonstrated. The approach taken is based on the failure detection and isolation (FDI) theory, and the resulting diagnostic systems can be implemented in on-board digital computers of passenger vehicles. The proposed diagnostic system, referred to as the binary phase detection filter (BPDF), uses a pair of failure-s... View full abstract»

    Research efforts have been made or are in progress on the application of machine vision to traffic monitoring and control. Of all the proposed systems, the wide-area detection system (WADS) appears to be the most reliable. However, limited field tests indicate that some malfunctions exist. Among these are false vehicle detection caused by sudden changes in road illumination and also by shadows or ... View full abstract»
