A wireless power transfer system for a vehicle traveling along a surface is provided. The wireless power transfer system includes a receiver coil mounted to the vehicle; a plurality of transmitter units connected in series and positioned on the surface; and a controller in communication with voltage sensors of each transmitter unit. The transmitter units include inactive and active transmitter units, and the inactive transmitter units include a leading transmitter unit and a trailing transmitter unit adjacent to the active transmitter units. The controller is configured to receive voltages of the leading and trailing transmitter units, compare the voltages with data in the database, and determine a position of the receiver relative to the transmitter units in order to activate and deactivate transmitter units as needed to dynamically modify the subset of active transmitter units to provide an efficient and smooth power supply to the receiver.

A control method and system of neutral section passing of multi-locomotive short broke trains. Distance traveled by a train after a primary multiple unit enters a neutral section is calculated in real time, so that a neutral section passing procedure of a secondary multiple unit is effectively controlled, thereby solving the problem that when the multi-locomotive short broke trains operate with double-raised pantographs, if the distance between the two pantographs is shorter than the length of a neutral zone of a neutral section and longer than the length of a no-electricity zone of the neutral section, when the two pantographs pass through the neutral sections, the two pantographs will span the two neutral sections and generate an interphase short circuit. The method improves safety of the EMU when it passing neutral section and ensure that the EMU can reliably pass through the neutral section with double-raised pantographs. The present invention has the advantages of being safe, reliable, easy to implement and convenient to promote and apply.

A vehicle controller is applied to a vehicle having an engine, a transmission, a clutch connecting and disconnecting a crankshaft of the engine and an input shaft of the transmission to each other, a vehicle wheel connected to a drive axle of the transmission, and an electric motor disposed to be capable of transmitting torque to the crankshaft The vehicle controller controls driving of the electric motor such that a rotation speed of the engine is reduced when an operation state of the engine shifts from operation to stop. The vehicle controller controls rotation of the crankshaft so as to avoid coincidence between a crank angle and a top dead center angle of the engine in a vibration amplification region amplifying an amplitude of vibration generated when the operation state of the engine shifts to the stop.

A dynamic capacitive power transfer system for an elevator that can realize the real-time powering of the elevator when it is in the moving status. It includes a metal track along the building side as the power transmitter and a piece of metal at the elevator side as the power receiver. There is a gap between the transmitter and receiver, and up to kW power can be transferred wirelessly and efficiently to serve the air conditioner, lightning, and other electronic devices in the moving car. The steel wheels and ropes may be used to connect the moving car to the earth ground, which contributes to form the current returning loop. It eliminates the electric cables and the corresponding flexible cable carrier system for the linear movement.
