A retrofittable remote control system is provided for enabling remote controlling of an on-board component of machine that is inherently incapable of being remote controlled. An interface control module is retrofitted on machine and is configured to communicate with off-board remote control over wireless communication channel. The interface control module detects presence of an on-board control module that communicates with the on-board component over a digital communication channel. The interface control module is configured to then establish either a digital communication link with the on-board control module or a direct Input/Output (I/O) communication link with the on-board component of the machine based on the detection. The interface control module is configured to send a control signal over either the direct I/O communication link or the digital communication channel via the detected on-board control module, for controlling the on-board component.

Retrofit remote control system for a machine

A method for controlling a machine during a transition from a service brake state to a parking brake includes receiving, by a control module, a request for activating a parking brake assembly. The method also includes transmitting, by the control module, control signals for activating a set of first brakes associated with a service brake assembly, a set of second brakes associated with the service brake assembly, and a clutch assembly. The method further includes controlling, by the control module, the set of first brakes for deactivating the set of first brakes. The method includes controlling, by the control module, the parking brake assembly for activating the parking brake assembly. The method also includes controlling, by the control module, the set of second brakes for deactivating the set of second brakes. The method further includes controlling, by the control module, the clutch assembly for deactivating the clutch assembly.

Method and control system for controlling machine

A method for shifting a transmission in a machine. The method includes detecting a request for a directional shift of the transmission and determining a ground speed of the machine in response to the request. The method further includes overriding the request if the ground speed is above a ground speed threshold. Further, the method includes preparing the machine for the directional shift by limiting an output speed of a power source of the machine and by issuing a command to a brake unit of the machine to reduce the ground speed of the machine. Furthermore, the method includes validating and raising the request to the transmission to execute the directional shift if the ground speed is below the ground speed threshold.
