Software, not hardware
Instead of relying on failure-prone mechanical sensors, the position of the overhead lines and current collectors is determined by way of stereoscopic pattern recognition using digital cameras. These signals control the components of the current collector system for precision disconnecting and recontacting.
Retrievers – a thing of the past
The software also enables dewiring – when the trolley poles inadvertently slip off the overhead wires – to be detected and the poles to be reliably repositioned and resecured via the actuators controlling pole movement. Collision is prevented with the overhead wires, the other trolley pole or other obstacles, thus making this system superior to those employing conventional mechanical retrievers.
Car-to-car communication
Digital communication (e.g. trunked radio or digital short range communication as per ITS-G5) is used to negotiate with other buses using the same overhead line to determine which of the two is to disconnect when passing or encountering a single pair of overhead wires.
Navigation via GPS and built-in digital map
Thanks to its GPS system (and other sensors), LibroDuct always ‘knows’ where the bus is located. This information is compared with a stored route map containing details showing where overhead lines may be expected that the bus may contact, and which of possibly several pairs of overhead lines is to be used.
Communication with the control centre
LibroDuct automatically receives route information updates for its digital map from the control center via its digital wireless interface so that the driver only has to input the route ID at the beginning of a journey. LibroDuct does everything else. LibroDuct is also able to use this interface to transmit information about critical situations, e.g. obstacles, to the control center for dissemination to other buses.
Energy-efficient operation thanks to intelligent technology
Using its digital map or statistical data from previous journeys, LibroDuct is able to predict the energy consumption and possible energy recuperation on the remaining portion of the route to be covered by the bus. This information is used by LibroDuct to optimize energy use and storage in the energy accumulator.

双方向车共用一条线不太现实,还是架双线吧

这样导致偏线距太短

集电杆不需改动啊,只是捕捉架空线的范围仅限于车顶,车宽的范围内

集电杆是套在3里的不是?左右偏线范围被限制在2的长度内了不是?
