Filed: 2022-02-16
Abstract: PROBLEM TO BE SOLVED: To provide a tracked vehicle with a rotary upper structure, and a process used to control operations of such a tracked vehicle. 
     SOLUTION: A tracked vehicle comprises: 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 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.
