Abstract: Embodiments include a method and noise cancelling system for cancelling noise in a vehicle by operating at least one noise cancelling means in a first mode of operation to output a noise cancelling signal; receiving at least one input indicative of a state of the vehicle; determining if noise cancelling error conditions are present based on the at least one received input indicative of a state of the vehicle; and operating at least one noise cancelling means in a second mode of operation if noise cancelling error conditions are determined as present.

Abstract: Embodiments of the present invention provide an in-vehicle privacy system, comprising audio output means (146, 147) associated with a first zone (110) of an interior of a vehicle (100), audio source means (250) for providing an audio signal (205) to the audio output means (146, 147), speech intelligibility means (310) for estimating a speech intelligibility in the first zone (110), control means arranged to control one or more properties of the audio signal (205) in dependence on the estimate of speech intelligibility to mask speech of a second occupant in a second zone (150) of the interior of the vehicle (100) from a first occupant with the first zone.

Abstract: Aspects of the invention relate to a switched reluctance motor and the reduction of motor torque output ripple by inclusion of flux barriers. The inclusion of flux barriers running parallel to the motor shaft axis located in the appropriate places in either or the rotor and stator can modify the torque profile output of the motor markedly reducing potential vibration problems in a vehicle driveline.

Abstract: In one aspect of the invention for which protection is sought there is provided an electric machine comprising a substantially circular rotor and a stator, wherein the stator comprises at least one substantially arcuate segment. Aspects of the invention also relate to a stator segment comprising at least one inter-pole shield disposed between adjacent teeth. Further aspects of the invention also relate to a stator segment having a first shield disposed at a first circumferential end thereof and/or a second shield disposed at a second circumferential end thereof. Aspects of the invention also relate to a stator segment having a radially outwardly directed protuberance.

Abstract: The present application relates to an electric machine (1) including a rotor (13) and a stator (11). The stator has a first set of teeth and each tooth in the first set has a first winding (21) The stator also has a second set of teeth and each tooth in the second set has a second winding (41). The first winding (21) has a first winding count and the second winding (41) has a second winding count. The first and second winding counts are different from each other. The electric machine has particular application in cranking an internal combustion engine. The present application also relates to a related control apparatus (50) and a vehicle.
