S5: the state that separated time actuator judges current deconcentrator whether with drive towards self in self cog region current and point lane controller nearest apart from self requirement of separated time request of sending is consistent, if so, then perform S6, otherwise perform S11.
S6: separated time actuator drives towards self in self cog region current and point lane controller nearest apart from self sends separated time request response signal, and continues to perform S7.
S7: receive the trackless electric car of public traffic point belonging to lane controller of the separated time request response signal that point lane controller sends by current crossing, and separated time actuator sends separated time success message to point lane controller on this trackless electric car of public traffic after this trackless electric car of public traffic is completely by the current crossing of firm separated time, performs S8 subsequently.
S8: point lane controller receiving separated time success message preserves this car, and this preserves by the separated time record during crossing recorded information that this car to keep straight at this crossing or turn round, and performs S9.

S12: separated time actuator is according to driving towards self in self cog region current and the requirement change deconcentrator state of the separated time request that divide lane controller send nearest apart from self, and redirect performs S6;
S13: wait for the first predetermined time interval T
1after return this S11.
Below for convenience of description, for the bus of 12 meters long, the method for splitting that the utility model embodiment provides is described.
The first situation: many trackless electric car of public traffic arrive intersection simultaneously, but only have point lane controller of a car in the cog region of separated time actuator.According to method provided above, in this situation, if drive towards intersection and trackless electric car of public traffic in the cog region of separated time actuator only has one and this car sends separated time request, then the separated time request that point lane controller that separated time actuator only processes this car sends.
The second situation: two even many trackless electric car of public traffic drive towards intersection, and all in the cog region of separated time actuator simultaneously.In such cases, for convenience of describing, for two electric cars, if first electric car is greater than the distance of second tramway separated time actuator to the distance of separated time actuator, length due to electric car is 12 meters, therefore the distance between first electric car and second electric car is at least 12 meters, and within the scope of 20 meters the error of wireless distance finding be to the maximum ± 2 meters, so, as long as setting: namely this situation can be converted into upper a kind of situation and process by the decipherment distance=separated time actuator of separated time actuator and the distance of second electric car+(first electric car is to the distance of second electric car) ÷ 2.In such cases, preferably, following method can be adopted to process: when second electric car of close together sends separated time request, only drive towards crossing in response cog region and the separated time request of second electric car nearest apart from separated time actuator, if second electric car does not send break a case ball, and there is the separated time request of first electric car, the separated time request of first electric car can be kept in, wait for the 3rd of short duration predetermined time interval T3, again judge whether a point lane controller for second electric car sends separated time request, if, then perform its separated time request, otherwise, then must wait until that first electric car is less than second electric car to the distance of separated time actuator and deviates from the separated time request that could respond first electric car when separated time actuator travels by crossing completely to the distance of separated time actuator or second electric car.The execution efficiency of this point of wire system can be improved so further.Generally speaking, above-mentioned method for optimizing for: drive towards after the nearest point lane controller of all points of lane controller middle distance separated time actuators of separated time actuator do not send separated time request in the cog region judging separated time actuator in step S4 shown in Fig. 6, before returning execution S2, also step can be comprised: separated time actuator waits for the 3rd predetermined time interval T
3, whether point lane controller driving towards all points of lane controller middle distance separated time actuators of separated time actuator in the cog region again judging determined separated time actuator in previous step nearest sends separated time request, if so, then performs S5, otherwise, just return execution S2.
The third situation: two even more trackless electric car of public traffic simultaneously in the cog region of separated time actuator, but be distributed in the both sides of separated time actuator, and the trackless electric car of public traffic of side drives towards crossing residing for separated time actuator, opposite side sails out of crossing namely to deviate from separated time actuator traveling.In such cases, according to the thought of the method for splitting that the utility model provides, first separated time actuator should respond and be positioned at self cog region and drive towards self and from the separated time request of self nearest point of lane controller, but opposite side may be there is deviate from a point lane controller that separated time actuator travels and may just carry out separated time and also do not pass through crossing completely, namely need to consider the ageing of separated time actuator controlling functions, namely must ensure to be positioned at the cog region of separated time actuator and drive towards separated time actuator and separate the nearest point lane controller of line actuator and sailing out of the control of point lane controller at crossing in the strongest the completing of the cog region arriving signal of separated time actuator to just carrying out separated time and removing controlling functions, otherwise, separated time actuator is driven towards and the route separating the nearest point lane controller of line actuator will occur mistake in the cog region being currently located at separated time actuator.Visible, in method shown in Fig. 6, step S11-S13 solves this problem that in this case may exist.Preferably, when trackless electric car of public traffic length is 12 meters, due to the error of wireless distance finding within the scope of 20 meters be to the maximum ± 2 meters, therefore, in S11, predetermined distance threshold is 14 meters.
4th kind of situation: two trackless electric car of public traffic simultaneously in the cog region of separated time actuator, but run to two different directions
5th kind of situation: the while of two trackless electric car of public traffic in the cog region of separated time actuator, but all in subtend track.
