      <title>INVESTIGATING RAILWAY OPERATING SEQUENCES WITH THE AID OF SIMULATION MODEL SIMU V</title>
      <link>https://trid.trb.org/View/271312</link>
      <description><![CDATA[SIMU V in the FORTRAN programming language is a programming system used in the computer of Lower Saxony's regional computing center for the simulation of the sequence of operations in tracked transport systems.  The usefulness of the simulation model, with which sequences both in complex passenger stations and in networks of a size up to 500 track-kilometers can be represented, has been shown in many applications in the dimensioning of new transport installations and in the evaluation of planning variants. In addition to the main SIMU V model components, the authors also describe the S5-SUCHE programming system for dialog-oriented data preparation and management on a microcomputer.

      <title>LONGITUDINAL AND LATERAL VEHICLE CONTROL SETUP IN THE FLEXIBLE LOW-COST AUTOMATED SCALED HIGHWAY (FLASH) LABORATORY</title>
      <link>https://trid.trb.org/View/463687</link>
      <description><![CDATA[This paper describes the setup for longitudinal and lateral control experiments in the flexible low-cost automated scaled highway (FLASH) laboratory being developed at Virginia Tech. The laboratory is a proposed 1/15th scale hardware working model of Automated Highway Systems (AHS), and is being designed to conduct many experiments as part of a four block evaluation methodology for AHS.  The vehicles are equipped with ultrasonic sensors for longitudinal guidance and infrared sensors for lateral guidance. They are controlled by HC11 microprocessor boards, and have wireless two way communication infrastructure for vehicle-highway communication.]]></description>

      <title>MORE ELECTRONICS IN DETROIT'S 1985 MODELS</title>
      <link>https://trid.trb.org/View/215773</link>
      <description><![CDATA[After years of experience with electronic devices and systems in cars, automobile manufacturers are moving toward a more mature, integrated-systems approach to design.  In some 1985 cars microprocessors communicate with each other, sharing input data, to provide more precise control of car functions.  Single instruments are programmed to give multiple readouts.  And instruments, on-board diagnostics, and navigational systems are designed to share one overall display.  The paper reviews the innovations in 1985 cars giving particular attention to systems integration, travel aid systems, improved diagnostics aid servicing, engine control, load leveling suspensions, advanced displays, and new electronic antilock braking systems.]]></description>

      <title>MICROCOMPUTERS ASSIST CONTROL OF TRACTION VEHICLES AND PASSENGER COACHES</title>
      <link>https://trid.trb.org/View/218302</link>
      <description><![CDATA[BBC's new generation of programmable, modular control equipment for traction vehicles were created to meet a whole series of important requirements brought about by important developments in the traction field.  Functions at the train and vehicle control levels are performed by a single-board computer which is programmed in a user-friendly language made up of function blocks.  The control functions at the drive control level are performed by highly integrated single-chip computers.  The authors explain the advantages to the user of BBC's new generation of programmable, modular control systems.]]></description>

      <description><![CDATA[Sweden's Saab-Scania has developed a computer-aided gear-changing system that allows the driver considerable operational control.  A microprocessor advises the driver when to change gears.  It then suggests a suitable ratio. The transmission is shifted via 3 actuators of the type normally used on Scania's manual splitter or range units.]]></description>

      <title>DETROIT ZEROS IN ON SAFETY AND EFFICIENCY</title>
      <link>https://trid.trb.org/View/211658</link>
      <description><![CDATA[Ford's anti-lock brake system is considered which is available on special Lincoln Mark VII and Continental models.  The system features four wheel mounted speed sensors which send signals to a central microprocessor.  The microprocessor compares the rotational speeds of all four sensors.  If one wheel starts to slow down more rapidly than the others during braking, indicating potential wheel lock, the computer signals the appropriate hydraulic braking circuit to pulse the braking pressure to that wheel or axle.]]></description>

      <title>USE OF A MICROCOMPUTER IN AN ELECTRONIC FUEL GAGE MODULE</title>
      <link>https://trid.trb.org/View/161630</link>
      <description><![CDATA[The electronic fuel gage being used in the 1980 Mark/Lincoln/Thunderbird/Cougar XR7 has minimal basic system logic requirements.  However, by incorporating a microcomputer, it was possible to reduce the cost and complexity of other components in the module.  As the design and development of the electronic fuel gage progressed, the need surfaced for additional features that had not been identified at the beginning of the program.  The microcomputer provided the flexibility to add these features and still meet the cost and timing constraints of the program.]]></description>

      <title>NEW SHIFT IN ON-BOARD COMPUTERS</title>
      <link>https://trid.trb.org/View/208956</link>
      <description><![CDATA[Electronically-controlled automatic transmissions are described that have replaced video arcade instrument panels in many Japanese cars.  The automatic transmission's control system consists of an electronic assembly and a number of transducers which supply electrical signals for an electronic circuit.  That circuit mixes these signals and performs a calculation in response to a predetermined algorithm, which commands two valves that provide the interface between the electronic control system and the hydraulic/mechanical system of the transmission.  The electronic circuit is organized around a microprocessor.]]></description>

      <description><![CDATA[Hitachi has been developing a motor voltage regulator (MVR) having such new functions as self-check, failure memory, and monitoring by adopting direct digital control (DDC) using microprocessors in order to make electric locomotives more reliable, maintainable, and controllable.  Improvements of control characteristics are reported in a bench test of a prototype MVR with DDC for ac electric locomotives (continuous rated output: 3000 kw).]]></description>

      <title>MICROPROCESSOR CONTROLS ENGINE AND TRANSMISSION</title>
      <link>https://trid.trb.org/View/201763</link>
      <description><![CDATA[A microprocessor-based engine and transmission control system has been developed; its major characteristic is that many functions covered by hardware previously are not processed by software via a newly developed high speed microprocessor.  This unit has been used with 2.0-, 2.8-, and 4.0-L gasoline engines and a 2.4-L turbocharged diesel. The same engine control unit satisfies different requirements of each engine via software modification, and uses the fewest input/output interface changes and least additional memory possible.]]></description>
