    The technical issues that the Advanced Vehicle Control Systems (AVCS) Committee of the Intelligent Vehicle Highway Society (IVHS) of America has identified as necessary to improve the performance of the surface transportation system are discussed. AVCSs represent the application of sensors, computers, and electromechanical actuators to provide drivers with warnings of hazards, assistance in controlling their vehicles, or fully automated control of vehicle motions. The constraints under which AVCS enabling technologies must be brought to maturity, such as cost, reliability, fault tolerance, and environmental hardening, combined with the basic performance requirements, are outlined. The enabling technologies for AVCS, subdivided into categories of sensors, communication, computation, electromechanical actuators, software and systems technologies, and special tools and facilities, are discussed. AVCS target products are reviewed.<> View full abstract»

    An onboard autonomous intelligent cruise control system which controls a vehicle's speed according to the driver's desire and the speed of and distance to the preceding vehicle is discussed. The system offers a one-directional short-range system for vehicle-vehicle and roadside-vehicle communication and considerations for recommended speed, limits, and traffic signals. It is a potential key element in linking and integrating the driver-vehicle-infrastructure in future intelligent transportation systems. Two field trials undertaken to determine the feasibility of the system are described.<> View full abstract»

    The activities of the European Prometheus project's PRO-CHIP research groups, which have studied the problem of improving automotive electronic reliability while respecting the specifications of low-cost, high-volume production, light weight, compactness, and short time-to-market imposed by the automotive industry, are reviewed. The reliability problems most frequently encountered by electronic devices for automotive applications, including failure mechanisms due to the package or to the assembling technology, different kinds of electrical overstress, electrostatic discharge, electromagnetic interference, breakdown and burnout of power devices, and failure mechanisms accelerated by high temperatures and high current densities, and the procedures the manufacturers use to evaluate and improve the reliability of their products are discussed.<> View full abstract»

    The performance and architecture of a high dynamic range camera (HDRC) chip and the conceptional advantages for its adaptation to image processing systems in traffic environments are discussed. The HDRC chip was developed with 64*64 pixels using a standard digital 1.2- mu m CMOS technology. It is shown that the implementation proves the functionality and indicates the system performance of a highly dynamic range camera is feasible.<> View full abstract»

    A solution to autonomous lateral vehicle guidance using a neurocontroller that can learn from measured human-driving data without knowledge of the physical car parameters is discussed. Simulations and practical tests confirm that a small-size feedforward autonomous neural network (21 neurons) can learn to steer a vehicle at high speeds only from looking at human-driving examples. In this way, the network learns the total closed-loop behavior, including the nonlinear dynamics of the vehicle and the driver's individual driving style. The main result of practical investigations is that the neutral controller trained on human-driving examples exhibits an aperiodic behavior that does not vanish at higher speeds (tests performed up to 130 km/h) and produces fewer lateral deviations than the linear state controller.<> View full abstract»
