A method for automatic stop comprises: acquiring a target distance correction value, wherein the target distance correction value is determined according to a historical parking error value before a target moment, and the target moment is the time when the target distance correction value is stored; correcting an acquired target distance value according to the target distance correction value, so as to obtain a corrected target distance value, wherein the target distance value is the value of the distance between the current position of a vehicle and a target parking position; and according to the corrected target distance value, executing the present instance of automatic parking. An automatic parking apparatus may be used to carry out such a method.

A positive train control may comprise a plurality of different sensors coupled to a processor that determines whether there is an anomaly of a track way, and if there is, provides an alert and/or a train control action. The plural sensors may include a visual imager, an infrared imager, a radar, a doppler radar, a laser sensor, a laser ranging device, an acoustic sensor, and/or an acoustic ranging device. Data from the plural sensors is geo-tagged and time tagged. Some embodiments of the train control employ track monitors, switch monitors and/or wayside monitors, and some employ locating devices such as GPS and inertial devices.

A system and method for virtual block stick circuits is presented. The present disclosure implements specialized algorithms adapted to determine the true status of a virtual block based on multiple inputs from different perspectives. In one embodiment, the system can use the far house perspective of that virtual track segment and the PTC hazard for the near virtual track segment directly adjacent to the near house uses the near house perspective of that virtual track segment. For the middle virtual track segments, the near house perspectives of the middle virtual track segments are held ‘TRUE’ if they are already ‘TRUE’ when the train first enters the block, using stick circuits for the near house perspective of the middle track circuits. The vital application can then indicate the true state of the virtual track segment as occupied (FALSE), to protect the train from trains that follow.

An inspection system for inspecting the track of an amusement ride with at least one rail. A vehicle is provided that is designed to ride along the track. The vehicle supports cameras. The cameras are positioned in unobstructed areas. The cameras image the rail from different angles as the vehicle rides along the track. The images recorded by the cameras are reviewed to identify any defect or issue with the rail or its supporting framework that may impact from the safety of the ride.

There is provided an automatic train operation system which can stop a train precisely at a stop target position without worsening ride quality even with the control system being a discrete system. The automatic train operation system comprises a relative distance measuring device to acquire information about a relative distance of the train relative to a stop position of a station to output average distance information that is the average of relative distances and a brake control device. The brake control device includes a sensor information holding unit to hold speed information and position information detected by sensors to output; a correction amount computing unit to compute a specifying value correction amount to output; and an instruction planning unit to compute a deceleration specifying value based on the specifying value correction amount and sensor information.
