    Considers the synthesis and analysis of a robust controller for autonomous lateral control of a vehicle. The controller is designed using the LMI-based design approach of a gain scheduled H∞ controller. System modeling for gain scheduling and controller synthesis steps are detailed.

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (328 KB)

    Estimation methods of the driving state (position, velocity, acceleration) and the lane displacement of forward vehicles are proposed. The lane displacement denotes the lateral displacement from the host vehicle's running lane. The driving state of each vehicle is estimated using Kalman filter; and it is corrected in the case that the estimation error becomes large, which means the acceleration ch... View full abstract»

    Publication Year: 1997, Page(s):183 - 188
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (484 KB)

    The Metropolitan Expressway Public Corporation has studied the establishment of a new telephone system which receives the designation of an origin (entrance) and destination (exit point) by a user through a telephone and provides information only related to the zone that the driver will actually use. A simulation was then developed to compare the new system to the one in current use in terms of th... View full abstract»

    Knowledge of an automobile driver's intended actions (e.g., to turn, change lanes, etc.) could facilitate the integration of intelligent vehicle systems with the driver. The actions can be inferred from the driver's control actions as he/she prepares to execute an action. Actions are modeled as a sequence of internal mental states, each with a characteristic pattern of driver control behavior. By ... View full abstract»

  • Taxi despatch: a fuzzy rule approach

    Cited by:  Papers (4)
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (280 KB)

    The problem of taxi despatch from a pool of taxies, either waiting at the taxi stand or plying free in the city is addressed. Calls for taxies may emanate from different parts of the city. The taxi stand operator is aware about the status (i.e. waiting, busy, free) and position of all taxies associated with the taxi stand at any time. While despatching the taxi for a call, the operator should cons... View full abstract»

  • Vehicle matching using color

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (532 KB)

    We describe a vehicle matching algorithm, which is part of our AutoColor traffic monitoring system, that can identify the same vehicle at different camera sites using color information only. This work is challenging since vehicle color varies with daylight illumination which is unpredictable. We present a novel color matching approach that takes advantage of road color variation to model changes i... View full abstract»

    The Michigan Offroad Sensor Fusing Experimental Testbed (MOSFET) is an autonomous vehicle designed to navigate an unknown terrain which includes obstacles, lanes, and other traditional roadside obstructions. In order to gather data about the world around it, MOSFET is equipped with several heterogeneous sensors. These sensors include one forward-looking camera used for obstacle detection and lane ...

    Deals with analysis of the dynamic behavior and collective rule organization in a motor vehicle traffic model on a non-signal street. In the non-global information and operating model, we analyze how individual agents affect the “rule” which exists as a common knowledge in the city, and investigate a process of rule organization. Experimental results imply that the rule organization pr... View full abstract»

    This paper describes algorithms of path generation and lateral control of an automated vehicle with a vision system for autonomous navigation and lane-change manoeuvres. The vision system detects reference lines along which the vehicle is guided. The lateral control consists of steps of reference line detection, path generation, and lateral control calculation. A coefficient of a cubic curve that ... View full abstract»

    Cited by:  Papers (13)  |  Patents (1)
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (408 KB)

    A traffic sensing technique is described which utilizes a microphone array to detect the sound waves generated by the road vehicles. The detected sounds are then digitized and processed by an on-site computer using a correlation based algorithm, which extracts key data reflecting the road traffic conditions, e.g. the speed and density of vehicles on the road, automatically on-site. In comparison w... View full abstract»

    This paper presents the hardware and software architecture and the system requirements, design and measurements of a 24 GHz radar sensor for collision avoidance applications. The radar uses FMCW modulation and time/frequency channelization to attain interference tolerance with other radars. The millimeter wave module was fabricated from GaAs PHEMT MMICs developed during the program. The MMICs and ... View full abstract»

  • Using order statistics for object tracking

    Publication Year: 1997, Page(s):712 - 716
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (584 KB)

    We propose a new model free approach to object tracking. It is based on the estimation of the location and scale parameter of a feature distribution by using asymptotic properties of order statistics. The basic distribution considered is the distribution of the coordinates of some kind of low level localized features, e.g. edges. A robust and real time tracking behavior is achieved by the algorith... View full abstract»

    This paper presents a way to design a lateral controller for an automated vehicle using information gained through image processing with the control objective being to stay on a desired path. Two possible ways to obtain the information necessary for lateral control by image processing are presented, one based on pixel intensity summation and the other on vanishing point calculations.

    This paper discusses the role of dedicated lanes in the automated highway system (AHS). Dedicated lanes are defined and compared with mixed traffic lanes. Discussion of the safety of dedicated lanes includes a look at obstacles in the right-of-way. Additional topics discussed in this article include: increased throughput on dedicated lanes, interchange issues, simulations findings, the affect of d... View full abstract»

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (400 KB)

    To optimize the performance and reduce the emission levels of an internal combustion engine one needs some measurements of the combustion process duality. We propose two artificial neural network models which use the ionization current for estimation of the position of the pressure peak and the air-fuel ratio. The pressure peak position model produces estimates on a cycle-by-cycle basis for each o... View full abstract»
