Abstract

Abstract This invention relates to a method of automatic vehicle operation which fulfills multi-dimensional performance indices by presetting the weight for power consumption, the weight for the riding confort, and the like. The modifying running time relative to the standard running time to be spent between two stations, the allowable power consumption relative to the standard power consumption to be spent for the standard running between two stations, and the degree of improvement of riding confort for the standard running between two stations are set prior to the departure from a station so as to determine control parameters to be used for divided regions of distance between two stations, and the speed of the vehicle between two stations is controlled using the selected control parameters.

Claims Analysis

Total Claims: 11
Claim 1
Independent Claim 80 words
A method for automatic operation of a vehicle in which predetermined control parameters are used to control the operation of a vehicle between two stations, wherein a plurality of sets of control parameters are prepared, performance indices reflecting the result of running of said vehicle when each of said control parameters is used for divided regions of distance between two stations are obtained, and a control parameter used in each region is determined by setting said performance indices in advance.
Claim 2
Independent Claim 80 words
A method for automatic operation of a vehicle in which predetermined control parameters are used to control the operation of a vehicle between two stations, wherein a plurality of sets of control parameters are prepared, performance indices reflecting the result of running of said vehicle when each of said control parameters is used for divided regions of distance between two stations are obtained, and a control parameter used in each region is determined by setting said performance indices in advance.
Claim 3
Dependent Claim 29 words
A method of automatic vehicle operation according to claim 1, wherein said performance indices include running conditions such as running time between two stations, power consumption, and riding confort.
Claim 4
Dependent Claim 43 words
A method of automatic vehicle operation according to claim 1, wherein said performance indices are set by operating switches (7, 8 and 9) provided on said vehicle or transmitted from a computer (6) in a central operation command office through a communication line.
Claim 5
Dependent Claim 43 words
A method of automatic vehicle operation according to claim 2, wherein said performance indices are set by operating switches (7, 8 and 9) provided on said vehicle or transmitted from a computer (6) in a central operation command office through a communication line.
Claim 6
Independent Claim 148 words
A method of automatic train operation of a train between stations using predetermined control parameters with one or more ground markers placed between stations, comprising a first step of recording the train speed, residual running time and scheduled power consumption after the train has passed each of said ground markers on a schedule of minimum running time; a second step of recording the increased value of running time and decreased value of power consumption in case the lower target train speed is lowered when the train passes each of said ground markers; and a step of determining, when the train passes each of said ground markers, a lower target train speed which demands the least power consumption and satisfies a target running time to be spent until the train reaches an arriving station, said target running time being preset before the train has started from a departing station.
Claim 7
Independent Claim 148 words
A method of automatic train operation of a train between stations using predetermined control parameters with one or more ground markers placed between stations, comprising a first step of recording the train speed, residual running time and scheduled power consumption after the train has passed each of said ground markers on a schedule of minimum running time; a second step of recording the increased value of running time and decreased value of power consumption in case the lower target train speed is lowered when the train passes each of said ground markers; and a step of determining, when the train passes each of said ground markers, a lower target train speed which demands the least power consumption and satisfies a target running time to be spent until the train reaches an arriving station, said target running time being preset before the train has started from a departing station.
Claim 8
Dependent Claim 65 words
A method of automatic train operation according to claim 5, wherein said lower target train speed is determined by first setting a lower target power consumption with reference to a table of potential energy possessed by the train in correspondence to a running distance from the departing station, and next by subtracting a current potential energy of the train from said lower target power consumption.
Claim 9
Dependent Claim 47 words
A method of automatic train operation according to claim 5 or 6, wherein said increased running time and decreased power consumption are recorded in a plurality of columns of table with priority levels appended thereto, so that a column of table is selected on a proirity basis.
Claim 10
Dependent Claim 42 words
A method of automatic train operation according to claim 5, 6 or 7, wherein said ground markers placed between stations is substituted by positional information which is derived from a running distance measured since the train has started from the departing station.
Claim 11
Dependent Claim 54 words
A method of automatic train operation according to claim 5, 6, 7 or 8, wherein said lower target speed or lower target power consumption is determined based on a target power consumption or the combination of a target power consumption and target running time instead of being determined solely from the target running time.
