Abstract: Aspects of the present invention relate to a control system for detecting a wheel slip event of a vehicle having a plurality of wheels (W1-W4). The control system includes one or more processors collectively configured to receive a plurality of linear velocity signals (SLC1-SCL4), each of the plurality of linear velocity signals (SLC1-SCL4) indicating a linear velocity of one of the wheels (W1-W4). A dispersion threshold (DTH) is determined for the linear velocities indicated by the plurality of linear velocity signals (SLC1-SCL4). A wheel slip detected signal is output in dependence on a determination that a range (RLV) of the linear velocities is greater than the determined dispersion threshold (DTH). Aspects of the present invention also relate to a system, a vehicle, a method and computer readable instructions.

Abstract: Transmissions in which the mechanical gear shift arrangements are replaced by electro-hydraulic operated shift mechanisms that have to be able to be neutralised positively to ensure a proper operation. An arrangement and method are provided to determine the position of the shift rail so a shift can be made only if the conditions are right. To prevent engagement of two shift members at the same time and consequent damage in case of electronic failure, mechanical safety features such as detents are included.

Abstract: A shift control method for an automated manual transmission is provided. The method includes the step of modulating the force applied to a shift collar, via a shift rod and/or shift fork for example, during the engagement of the shift collar and a selected gear. The method modulates the initial engagement force applied to the shift collar when the rotational speed differential between the collar and gear is being adjusted, before increasing the force again following modulation. This modulation of the force decelerates the shift collar during the rotational speed adjustment and does not accelerate the shift collar to complete the engagement until after the modulation. In this way, a less abrupt engagement of the gear may be achieved. The control method may improve the driving characteristics of the vehicle employing the transmission and may also improve the power transmission efficiency.

Abstract: A fresenel zoned microstructured optical fibre is described. The fibre is constructed of concentric zones, each zone being defined by discontinuities in the refractive index. The refractive index within each zone may either be constant or may vary, for example each zone being a section of a parabola or hyperbola. The fibre may be used as a lens, for example for coupling light between fibres with different core sizes.
