A work machine using a distributed controller network that provides for redundant data buses is described herein. The work machine uses a controller area network that provides for redundant data buses for tiercontrollers, or controllers that are determined to have a higher degree of importance when compared to other controllers. The controller area network uses redundancy to decrease the probability of a communication failure between tiercontrollers and tiercontrollers. The tiercontrollers have communication access to two data buses between other tiercontrollers and tiercontrollers. Thus, if a data bus used by a tiercontroller cannot be used by the controller, the tiercontroller can use the other, redundant data bus to maintain communication.

Systems and methods for operating a controller area network

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 system for detecting distribution of a weight of a payload in a dump body of a vehicle includes first sensors, second sensors, and a controller. The dump body is pivotable about pins to be selectively seated and titled to a frame of the vehicle. The first sensors are arranged between the dump body and the frame, and detect components of the weight of the payload exerted through the dump body when the dump body is seated relative to the frame. The second sensors are arranged correspondingly within the pins, and detect components of the weight of the payload exerted through the dump body. The controller determines a status of payload distribution in the dump body based on the component of the weight of the payload detected by the first sensors and second sensors, and generate a notification to indicate the status of payload distribution.

System and method for detecting distribution of weight of payload in dump bodies

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.
