A method comprising:receiving sensor data from a sensor on a vehicle;generating a first abstraction of the sensor data having a first level of abstraction detail and a second abstraction of the sensor data having a second level of abstraction detail;determining an attribute of a communications link…
A railway vehicle is provided with a pantograph movable under the action of a moving device between a raised position, in which it is able to cooperate in contact, in use, with a catenary conductor cable for drawing electrical energy, and a lowered position, in which it is lower than the height…
Disclosed herein is a battery module assembly having unit modules, each of which is configured to have a structure in which unit cells are loaded on a cartridge in a state in which the unit cells are electrically connected to each other via busbars, the battery module assembly including two or more…
The present invention relates to a train control device. The train control device sets an emergency brake pattern and a regular brake pattern as patterns of maximum speed according to the distance to a stopping point, and outputs a braking command when the train speed exceeds the maximum speed…
According to a vehicle controller, when a communication control unit (13) of a vehicle controller (1) acquires a variable control parameter from a server (5) via the Internet (4), the variable control parameter is stored in a write-enabled storage unit (11), and the user can change to a desired…
A short-circuit detector has connected between positive and negative terminals of a DC power source a series connection including sequentially a first switch, a first detection resistor, a second detection resistor and a second switch, a third switch between a grounding terminal such as a vehicle…
