    Abstract: A vehicle includes running wheels traveling on traveling road surfaces of tracks; a pair of position detection parts disposed at an interval in a width direction that output signals by detecting a distance from measured objects; a control unit controlling the amount of steering of the running wheels according to the signals from the position detection parts; and a steering mechanism steering the running wheels via the control unit. Each of the position detection parts outputs a signal having characteristics such that the output increases as the distance from the measured objects increases while an output change ratio is decreased in a range wherein the distance from the measured objects is not less than a predetermined value, and is configured such that, when the distance between one position detection part and the measured object is decreased, the distance between the other position detection part and the measured object is increased.

    Abstract: A railway safety critical application system substitutes commercial off-the-shelf (COTS) hardware and/or software for railway-domain specific product components, yet is validated to conform to railway safety critical system failure-free standards. The safety critical system uses a pair of tasks executed on a controller of a COTS personal computer or within a virtual environment with asymmetric communications capability. Both tasks receive and verify safety critical systems input message data and security code integrity and separately generate output data responsive to the input message. The first task has sole capability to send complete safety critical system output messages, but only the second task has the capability of generating the output security code. A failure of any of systems hardware, software or processing capability results failure to transmit a safety critical system output message or an output message that cannot be verified by other safety critical systems.
