Embodiment 1

[0040] refer to Figure 1 to Figure 5 , in an embodiment of the present invention, an automatic control method applied to the reliability of the driverless bus timetable is provided. First, based on the GPS system, vehicle communication system and dynamic information transmission system of the driverless bus, the specifying the location information of the driverless bus, comparing the location information with the bus schedule corresponding to the preset driverless bus, and determining the actual driving state of the designated driverless bus, wherein the actual driving state includes On-time departure, early departure and late departure; then, collect the passenger flow of designated unmanned bus at each station on the set driving route, and calculate the passenger flow that can be boarded according to the accommodation space of the unmanned bus, and calculate the waiting time The boarding time of the passenger flow and the alighting time of the in-transit passenger flow, thr...

Embodiment 2

[0053] combine Image 6 with Figure 7 , and based on the description in the first embodiment, the automatic control method for the reliability of the timetable applied to the unmanned bus of the present invention is described again through a specific simulation experiment:

[0054] First, discretize the continuous time, for example, in the one-hour operation period from 8:00 to 9:00, divide it into 60 discrete time windows, let t=0 represent [8:00,8:01) , t=1 represents [8:01,8:02), t=2 represents [8:02,8:03), and so on; see Image 6 , it can be seen that when t=0, the unmanned bus is running normally, and x can be obtained at this time ij (t)=0, and y ij (t)=0, similarly the driving state of t=t+1, t∈T can be judged.

[0055] Subsequently, let t=t+1 until it is found that when t=5 and 6, the unmanned bus i is in the early departure, then optimize the model through the bus schedule, let x ij (t) = 1, t = 5, 6; when t = 7, the bus will start on time according to the set b...

Abstract

The invention discloses an automated control method applied to time table reliability of a driverless bus. The automated control method comprises the steps that data of the getting on and off passenger flow of the driverless bus at all stations, and the actual arriving moment and the departing moment of the driverless bus are collected in real time, and the data serve as input; a bus time table optimization model is established according to the necessary parking time and position information of the driverless bus at the stations; and the actual travelling state of the driverless bus serves asinput of the bus time table optimization model to judge, if the departing moment of the driverless bus is earlier than the planned departing moment, the driverless bus is controlled to stay at the stations and depart until the specified moment, and if the departing moment of the driverless bus is later than the planned departing moment, the operation speed between the stations is increased to reduce or eliminate delays. The reliability of on-time travelling of the driverless bus is enhanced, the quality of public transport service is advantageously improved, and great significance for promoting construction and development of a smart city in the future is achieved.

Description

technical field [0001] The invention belongs to the technical field of automatic control, and in particular relates to an automatic control method applied to the reliability of a timetable of an unmanned bus, and in particular to an automatic control method for stagnation and speed-up of an unmanned bus. Background technique [0002] Unmanned driving technology is an important component of future smart cities. At the same time, public transportation is an important means to solve modern urban congestion. Using advanced and intelligent technologies to promote the collaboration and development of unmanned driving technology and public transportation will become a key feature of the future society. Forward direction. [0003] Shen Jun, a scholar at Tongji University, pointed out that real-time dispatched driverless buses will become a revolutionary urban transportation tool in the future. Compared with traditional buses, the operation of unmanned buses has higher reliability. ...
