Maxim that wheel diameter table 401 storage cart wheel diameter may change and minimum value (being respectively maximum wheel diameter, minimum wheel diameter).These values are that the basis is predetermined with the statistical value of the wheel diameter that obtains according to experiment or the wheel diameter that rule of thumb obtains.The location information of the vehicle that speed protection mode table 402 storage is present, with stop position target information 108 cooresponding speed protection modes 105.Because speed protection mode 105 is determined uniquely according to the location information of present vehicle and the relation of stop position information 108 and vehicle performance, so according to present position information and stop position target information 108 concern preliminary evaluation speed protection mode 105, and be stored in the speed protection mode table 402.
In online location management portion 301, calculate vehicle 101 at line position.In Fig. 5, be illustrated in the structure of line position management department 301.Online location management portion 301 is made of position, front calculating part 501 and train length's calculating part 502.
In the position calculation that the is in advance portion 501, according to the revolution of the wheel that transmits by speed test section 202 and the wheel diameter table 401 of DB304 is extracted out in the car maximum wheel diameter and minimum wheel diameter, revolution is carried out integration and tries to achieve operating range, calculate the position, front of vehicle 101.At this moment, operating range is to be starting point with the location information that transmitted by at the moment ground installation 102, is undertaken by the revolution to after this wheel that the principal value of integral addition tries to achieve.The information of ground installation 102 is by transmitting to online location management portion 301 as communication unit 204 in the car of antenna with as the acceptance division 206 of demodulation section.Because the operating range that calculates is corresponding with the position that the position is set that has wheel, so with it and overhanging (overhang) addition till from the wheel to the front and try to achieve the position, front.The integrated value of maximum wheel diameter Rmax, wheel revolutions is Nr, the overhanging D of being if make, and then can represent the position, front with following formula.
Position, front=Rmax π Nr+D
Though calculated the position, front in the present embodiment, this is because speed protection mode 105 is the higher limits with the cooresponding speed in position, front, by different as the train position of system's GPRS with the position of speed protection mode 105 cooresponding trains.
Position, front calculating part 501, when transmitting the location information of ground installation 102 by acceptance division 206, the location information of abandoning calculating so far adopts the location information of ground installation 102 and the new value of overhanging addition as the position, front.
In train length's calculating part 502, tail behind the imagination growth train is handled.Fig. 6 represents to increase tail behind the train and makes the concept map of the processing that train length increases.According to the present invention, owing to use the maximum wheel diameter to calculate the position, front, the actual position of vehicle 101 is compared with respect to the direct of travel continued presence in the front with the grasp position of online location management portion 301.Therefore, under the situation of the speed limit zone 601 that has bending etc., front in speed limit zone 601, formation speed protection mode 105 makes speed is slowed down, but end in speed limit zone 601, be positioned at than the more close front of actual position then allow again and quicken if judge place by restricted areas, produce the possibility of running counter to speed limit.
At this, in train length's calculating part 502, with the actual location information that obtains the back tail of vehicle 101 of the corresponding calculating of operating range of the location information of coming to receive, the distance of itself and this position, front is managed as train length since at the moment ground installation 102.If it is X that order comes the operating range of the location information that free ground installation 102 at the moment receives, make the maximum wheel diameter is Rmax, make that minimum wheel diameter is Rmin, then can enough following formulas represent to obtain the distance error of the back tail of vehicle 101.
Distance error=X (Rmax-Rmin)/Rmax
By being worth with train length's addition tail behind the imagination growth vehicle, the operation that can observe speed limit zone 601.
Promptly, based on maximum wheel diameter and minimum wheel diameter, calculate the maximum distance error of operating range with the operating range of reality of the grasp of ground Train Control portion, with above-mentioned maximum distance error and the train length's addition that calculates, by use addition train length carry out Train Control, can imagination increase tail behind the vehicle, the operation that can observe speed limit zone 601.The rear end addition of maximum distance error that calculates at this moment, and train.
In addition, the maximum distance error of calculating is reset to 0 under the situation that receives location information from ground installation, and train length adopts predetermined train length.
In the present embodiment, though represented by ID, the location information transmission of train controller 103 earthward from vehicle 101, carry out the example of train detection, but only carry out in the method for train detection in ground side such as rail returns, cancellation can be implemented too from the transmission of the ID of car inner control portion 201, location information etc.
According to the present invention, because the change of wheel diameter often becomes minus side, actual position is compared with the position that Vehicular system is grasped becomes the front, so do not need to append the safe clearance distance.In addition, owing to the location correction of being undertaken by ground installation, become to be used to prevent to stop at and handle,, can reduce the quantity that is provided with of ground installation so do not need multiple conversion even under the situation that unexpectedly can not obtain, also be in secure side than the more close fwd of stop position target information.
Even also can guarantee safety in present situation because two ground installations are set, if so detect two miss (lost) (from taking defeat of ground installation) then carry out based on accident brake stop to handle, but in this case, have that the caused sensation of taking worsens and numerous and diverse (confirm to stop reason with ground, determined can set out behind the position etc.) handled that set out again is the problems such as time of departure again of the length of cause to be stopped by accident brake.
Even and do not need emergency braking under the situation about missing in the present invention yet, can stop lentamente by the speed protection mode, the sensation taken is worsened.In addition, even stop at the front owing to missing, also new model more when opening the place ahead route, can make sets out again becomes easy.That is, can not continue operation, improve so can expect operation factor owing to when missing, do not need basically promptly to stop in the present invention yet.
And then, with respect to results of regular determination wheel diameter in the past, in Vehicular system, reset, according to the present invention, do not need to change the wheel diameter of having set, also can expect the raising of maintainability.
