    A cost-effective, mixed technology process has been developed that extends the operating range of bipolar integrated circuits into the power integrated circuit regime. The process simultaneously produces CMOS (complementary metal-oxide-semiconductor) logic with a PNP vertical power device. The combination can withstand transients in excess of 85 V and jump start (24 V) and reverse polarity conditi... View full abstract»

    Requirements on instrumentation for automotive navigation systems are discussed, and liquid crystal display (LCD) equipment developed for this purpose is described. A direct multiplexed full-color LCD having 320*200 trio dots was developed and applied to a graphic display unit. Through the use of the newly developed COG (chip-on-glass) technology, a small and thin display module was realized. A ro... View full abstract»

    A dual-processor controller has been developed for evaluating advanced automotive control algorithms. The controller is architectured around a general-purpose microcontroller and a digital signal processor. The main goal of the design is efficient computation of mathematically oriented algorithms with the ability to interface with sensors and actuators. The effectiveness of the system architecture...

    The author describes a technique for linearization of analog signals produced by typical sensors in modern vehicle applications. With this technique, arbitrary linearization functions can be selected simply. The proposed digital linearization method overcomes many of the pitfalls of traditional linearization methods, at the expense of some additional hardware and more stringent requirements on the...

    Multiprocessor-based real-time control is discussed. A multiprocessor architecture is presented for the dynamic control of various engine, body, ride, and safety parameters. This architecture is extended to complex vehicles. Control of static body parameters is implemented by using a single-bit serial bus. Dynamic parameters such as the fuel/air mixture and spark timing are controlled by monitorin... View full abstract»

    The authors discuss the application of detection filters to the diagnosis of sensor and actuator failures in automotive control systems. The detection filter is the embodiment of a model-based failure detection and isolation (FDI) methodology, which utilizes analytical redundancy within a dynamical system (e.g. engine/controller) to isolate the cause and location of abnormal behavior (i.e. failure...

    A fuzzy logic controller with a built-in function for self-tuning of control characteristics has been applied to an automatic speed control device (ASCD) to create a robust system for production vehicles. Fuzzy logic is used to predict drivers' individual preferences for control characteristics when the vehicle speed is controlled to a set level by the ASCD system. The results are then reflected i...

    Two methodologies for designing a longitudinal controller for an automated vehicle are presented and compared. The first, parameter scheduling, involves a linearization of vehicle dynamics about a number of operating points, and the specification of an observer/controller compensator for each of those points. The second emphasizes an explicit accounting for nonlinearities in the selection of a non... View full abstract»
