  • ATO Automatic Train Operation
  • ATO devices have been introduced on many routes with the aim of reducing the burden on crews and reducing labor costs against the background of crowded train operation schedules and maintenance and improvement of home doors. There is. In recent years, in addition to regular operation and labor saving, which is the original purpose, reduction of power consumption is also required of ATO devices. On the other hand, for a route where the ATO device has not been introduced, introduction of a driving support device that supports the driver in driving operation has also been promoted so that driving can be performed with a traveling pattern with low power consumption.
  • the ATO device and the driving support device for the purpose of energy saving execute the traveling control and the driving operation support based on the traveling pattern with a small amount of power consumption derived in advance by simulation.
  • traveling can not be performed according to the traveling pattern derived by simulation due to conditions (for example, overhead wire voltage, boarding rate) different from the preconditions of the simulation.

Specifically, when traveling between stations in combination with constant speed traveling and coasting, the constant speed start determination unit that determines the timing to start constant speed traveling and the coasting start determination unit that determines the timing to start coasting A driving support system is disclosed that outputs a powering command / a constant speed command / a coasting command to a driving support device based on the remaining driving time.

  • the second is to support coasting at an appropriate position, which has a great influence on on-time performance while reducing power consumption ((2) in FIG. 8).
  • the former target speed support is often used relatively in the first half of inter-station travel (for example, at the point where acceleration after train departure ends), and the latter coasting position support is frequently used in the second half of inter-station travel ( There is a tendency of coasting utilization on downhill during cruise and coasting insertion before stop brake).
  • the recognition of the train location is calculated by integrating the vehicle speed based on the wheel rotation speed detected by the speed generator. Therefore, due to events such as wheel diameter error, integral error, or slippage / slippage, an error tends to be inherent in the recognition of the on-rail position especially in the latter half of traveling between stations. If the above-mentioned crawling support is continued when the accuracy of the recognition of the existing line position is deteriorated, the crawling can not be performed at an appropriate position. As a result, deviation from the planned travel pattern may lead to deterioration of on-time performance.

  • the driving support system 1100 described in the present embodiment it is possible to suppress the deterioration of the on-time performance and the energy saving performance even when the on-rail position detection accuracy is deteriorated.
  • the suppression of deterioration of the scheduled operation is as described in the first embodiment, the system side guarantees the suppression of the deterioration of the scheduled operation with respect to the support of the manual operation described in the present embodiment, so that the delay recovery by the crew is recovered. It is possible to suppress excessive powering operations aimed at reducing the energy saving performance.
