A tire/wheel assembly includes a wheel including a disk and a rim, the wheel having a power reception device attached to an outer peripheral surface of the rim to receive electric power supplied wirelessly from farther outward in a radial direction of the wheel than the rim, and a tire attached so as to cover an outer peripheral surface of the wheel and including a pair of sidewall portions. A gauge of the sidewall portions is 1.5 mm or more.

An insulated substrate (2) includes first and second circuit patterns (5,4). A semiconductor device (7) includes first and second main electrodes (9,8) connected to the first and second circuit patterns (5,4) respectively and through which main currents flow. A first lead (12) is solder jointed to the first circuit pattern (5). A second lead (11) is ultrasonic jointed to the second circuit pattern (4).

A brake force control apparatus allocates all of required brake force to a target front wheel friction brake force when the required brake force is equal to or smaller than a maximum regeneration brake force. The apparatus decreases the target regeneration brake force by a first predetermined amount at a first time point at which a front wheel acceleration varies from a value larger than a first acceleration threshold to a value equal to or smaller than the first acceleration threshold. The apparatus increases the target regeneration brake force in such a manner that the target regeneration brake force coincides with the required brake force, if the front wheel acceleration becomes larger than a second acceleration threshold in a period from the first time point to a second time point at which a predetermined time elapses from the first time point.

A method and arrangement are provided for controlling electric current in a tether cable of an electrically driven mining vehicle. An indicator of an equivalent cycle current that flows through said tether cable is determined, and one or more descriptors of an actual state of dynamically changing conditions of the tether cable are obtained. A current limiting value is determined on the basis of the indicator and the descriptors, and a total amount of current is limited that the mining vehicle draws through the tether cable to a value smaller than or equal to the determined current limiting value.

An infrastructure energy generation system comprising plurality of photovoltaic structures installed along a road or transportation route to generate electricity from solar energy. An electricity transmission line is installed along said road or transportation route which is connected to vehicle charging facilities, electric trains, electric buses, electric trucks, transportation facilities and roadside lights. The electricity transmission line is connected to at least one electricity generation source such as a generator or an electric battery. The infrastructure energy generation system is configured as a Distributed Energy Resource (DER), a microgrid, a grid-tied electrical system or an off-grid electrical system.

Methods and systems are provided for coordinating engine and motor torque in a hybrid vehicle system. The systems and methods use an engine torque command to obtain a motor torque command, and adjust the engine torque command based on an estimate of a time delay between commanded and actual motor torque prior to the engine command being sent to an engine controller. In this way, crankshaft torque accuracy may be improved.
