Abstract: A method of setting a clutch control reference value includes monitoring the pressure of a clutch while a controller applies test current having a predetermined amplitude and frequency to a solenoid valve in the manner of gradually reducing the magnitude of the test current from a predetermined entry value, applying, when the amplitude of the pressure of the clutch starts to change, predetermined checking current, the checking current vertically oscillating based on the magnitude of current when the amplitude of the pressure of the clutch starts to change as a central value, and determining a volumetric kiss point (VKP) by comparing the amplitude of the pressure of the clutch according to application of the checking current with a predetermined reference range.

Abstract: A method for extracting a get-on-and-off place where a vehicle may stop, which is performed by an operation server, includes, extracting vehicle road sections accessible by foot, filtering the extracted road sections by excluding a road section in which stopping of the vehicle is not permitted under traffic regulations, from the extracted road sections, selecting n quantity of virtual get-on-and-off places allowing getting on-and-off from the filtered roads, determining the walking time from each in all points of the service area to closest get-on-and-off place point, setting a longest time among walking times of all points of the service area, as a maximum walking time, and select a predetermined quantity of virtual get-on-and-off places from among the n quantity of virtual get-on-and-off places such that the selected maximum walking time is minimum, where the quantity k may be a natural number smaller than number n.

Abstract: A server for providing a passenger transportation service, may include a registered location database configured to store position information and image information related to each of previously registered get-on-and-off locations, a registered location management module configured to receive image data photographed from vehicles providing passenger transportation service during running and additional information including position information related to each of the image data, and update the image information based on the additional information by use of the image data, and a service providing module configured to, upon receiving a service provision request including position information and destination information related to a user from a user terminal, select a get-on location and a get-off location from among the get-on-and-off locations based on the position information and the destination information related to the user, and transmit get-on-and-off information including image data of the get-on location to the user terminal.
