An energy storage and transmission system (ESRS) (69) comprises a transmission (9, 11) and an energy storage device such as a flywheel (1). While energy is being transferred between the energy storage device (1) and an energy source/sink (7), the transmission ratio of the transmission (9, 11) will usually be changing constantly. In order to manage the torque applied by the energy transfer device (1) or the power transferred, a controller (100) responds to discrepancy between the torque or power supplied and the torque or power demanded.

The invention relates to a vehicle combination having a towing vehicle and a trailer, wherein the trailer has a drive which is coupled to a wheel of the trailer, wherein a control unit is provided and is designed to receive a signal of a sensor, wherein the control unit controls the operation of the drive as a function of the signal. Furthermore, the present invention relates to a method for controlling a drive in a vehicle combination.

A power assist device may include a motor, a motor driving circuit, sensors to output signals in accordance with a rotational speed of the wheel, a memory, and a signal processor. The memory stores information of a parameter defining a transfer function that interrelates a total torque to be input to the vehicle and a rotational speed of the wheel, and an inverse transfer function thereof. Based on the inverse transfer function, the signal processor determines an estimated value of total torque from a detected value of rotational speed of the wheel. Moreover, based on the transfer function, the signal processor updates at least a portion of the information of the parameter so that, for example, an error between a detected value of rotational speed of the wheel and an estimated value of rotational speed of the wheel as determined from the estimated value of total torque is reduced.

An agricultural vehicle and method of controlling the same are provided, the vehicle having a motive power unit providing a driving torque to at least one driven wheel and having at least one tire or track frictionally coupled with the periphery of the driven wheel. A vehicle operating parameter is controlled in dependence on the driving torque and a slippage characteristic relating the respective driving torque at which the frictional coupling between driven wheel and tire or track begins to slip for a range of vehicle operating parameter values. The operating parameter is suitably a tire pressure or track tension, and the control may involve reducing driving torque or increasing pressure/tension to prevent slipping.
