Abstract: Aspects of the present invention relates to a vehicle control system (1) for controlling a vehicle transfer case (3). The transfer case (3) is operable in a high range and a low range. The vehicle control system (1) is configured to output a range change signal to implement a transfer case range change. The vehicle control system (1) also outputs a brake control signal for controlling vehicle braking during the range change. The present invention also relates to a vehicle (5) and a related method of operating a vehicle control system (1) and optionally also a transmission (7).

Abstract: Aspects of the present invention relate to a vehicle control system (1) for controlling a vehicle transfer case (3). The transfer case (3) is operable in a high range and a low range. The vehicle control system (1) is configured to determine an operating range for the transfer case (3) based on a selected vehicle operating mode. A range change signal is output to implement a range change to engage the determined operating range. The present invention also relates to a vehicle (5) and a related method of operating a vehicle control system (1).

Abstract: Aspects of the present invention relates to a vehicle control system (1) for controlling a vehicle transfer case (3). The transfer case (3) is operable in a high range and a low range. The vehicle control system (1) includes a selection means (21) for selecting first and second control strategies for the transfer case. The first and second control strategies are based on an activation time of the selection means (21). A further aspect of the present invention relates to a vehicle control system (1) for implementing a deferred transfer case range change. The present invention also relates to a vehicle (5) and a related method of operating a vehicle control system (1).

Abstract: In response to driver selection of PARK, a vehicle transmission is commanded to momentarily select and hold NEUTRAL before PARK, while a vehicle wheel brake is applied. Such an arrangement avoids trapping torque in the driveline, and thus can obviate pawl ‘thump’ when PARK is next disengaged.

Abstract: The present invention relates to a method of engaging an input gear with an output gear in a drivetrain (3). The input gear is coupled to an input shaft (7) and the output gear is coupled to an output shaft (9). The method includes calculating a target input speed (S1?) for the input shaft (7) to match a rotational speed of the input gear to a rotational speed of the output gear. The calculated target input speed (S1?) is then modified to include an offset and the input speed (S1) of the input shaft (7) is then modified in dependence on the modified target input speed (S1?). The input gear and the output gear engage when the input speed (S1) of the input shaft (7) at least substantially matches the modified target input speed (S1?). The present invention also relates to an apparatus.

Abstract: The disclosure provides a process for producing a material with improved breakdown strength. The process includes heating a polymeric composition composed of a low density polyethylene (LDPE) and a minority amount of a high density polyethylene (HDPE). The polymeric composition is heated to at least the melting temperature of the HDPE. The process includes control-cooling the heated polymeric composition at a cooling rate from 0.1° C./min to 20° C./min, and forming a polymeric composition. The control-cooled polymeric composition has a unique morphology which improves breakdown strength. Also provided is a coated conductor with an insulating layer composed of the polymeric composition with the unique morphology. The insulating layer exhibits improved breakdown strength.
