Abstract: A process for execution by a processor of an electronic control unit (ECU), comprising: (a) detecting an operator command to align an upper structure of a tracked vehicle relative to a lower structure of the tracked vehicle; (b) in response to detection of the operator command, applying controlled rotation of the upper structure relative to the lower structure about an axis to align the upper structure relative to the lower structure at a predetermined relative angle; (c) in response to the upper structure having been aligned relative to the lower structure at the predetermined relative angle, signaling that alignment has been achieved; and (d) causing rotation of the upper structure to stop when alignment has been achieved and being non-responsive to further detection of the operator command during and for a predetermined period of time after said signaling. Also, a tracked vehicle comprising an ECU that executes the above process.

Abstract: A tracked vehicle comprising: a body comprising a lower structure and an upper structure rotatable relative to the lower structure about an axis; an angle sensor for detecting rotation of the upper structure relative to the lower structure; first and second track assemblies mounted, respectively, on opposite lateral sides of the body; a prime mover; an electronic control unit (ECU); and a transmission for controllably transferring power from the prime mover to the track assemblies based on an output of the ECU. The ECU is configured for responding to the angle sensor having detected a relative angular displacement in excess of a threshold angular displacement by: causing a signal to be emitted via an output interface to indicate that a directionality switchover is available to be requested; and, in response to detecting a directionality switchover request, causing the transmission to implement a directionality switchover for the tracked vehicle.
