Abstract

In some implementations, a controller for a hybrid powertrain system may cause disengagement of an engine from an electric machine via a clutch based on a state of charge (SOC) of one or more batteries connected to the electric machine at least meeting an SOC threshold. Disengagement of the engine may cause the hybrid powertrain system to operate in an electric-only mode for powering a load. The controller may detect a power event that includes at least one of a level of demand of the load exceeding a demand threshold, or the SOC of the one or more batteries being below the SOC threshold. The controller may cause, based on detection of the power event, engagement of the engine with the electric machine via the clutch. Engagement of the engine may enable the hybrid powertrain system to operate in a hybrid mode for powering the load.

Abstract

A worksite controller can manage machines, including a first machine configured to perform a first task and a second machine configured to perform a second task that follows the first task. The worksite controller can predict a time that the first machine will complete the first task at a work area. The worksite controller can also predict a time the second machine would arrive at the work area to perform the second task. Based on a comparison of the time the second machine would arrive at the work area and the predicted first task completion time, the worksite controller can instruct the second machine to enter or exit a low-power state. For example, if the second machine would arrive at the work area earlier than the predicted first task completion time, the worksite controller can instruct the second machine to avoid idling while waiting by entering the low-power state.

Abstract

Systems, methods, and apparatuses can determine weight of a machine using rolling resistance. The machine may be electrified, either all-electrically powered or partially electrically powered. The rolling resistance can be determined based on motor signaling from one or more motor sensors that sense motor characteristics (e.g., drawn current) from one or more electric motors that drive the machine. The weight of the machine can be determined using the determined rolling resistance. Weight information can be output for display on a display and/or for storing in computer-readable storage onboard and/or offboard the machine.

Abstract

In some implementations, a monitoring system may include a steering system of a machine, a sensor configured to detect movements of the steering system that are indicative of a steering angle of the machine, and a controller. The controller may be configured to monitor, via the sensor, the steering angle of the machine. The controller may be configured to determine, based on monitoring the steering angle, that the steering angle satisfies a threshold that is indicative of the steering angle being excessive for an operation of the machine. The controller may be configured to cause, based on the steering angle satisfying the threshold, the machine to provide an indication that the steering angle is excessive.

Abstract

In some implementations, a controller may determine whether a machine is operating in an autonomous mode or a manual mode. The controller may cause, based on a determination that the machine has been in an idle state for a first timer period, shutdown of an engine of the machine. The controller may monitor, based on a determination that the machine is operating in the autonomous mode, whether a condition for starting the engine is satisfied. The controller may cause, based on a determination that the engine has been shut down for a second timer period and that the condition is not satisfied, the machine to transition to a low power mode. The controller may cause, when the condition is satisfied, starting of the engine.

Abstract

A system for indicating a fluid level in a fluid tank of a machine includes a plurality of lighting units and at least one indicia. The lighting units are sequentially arranged with respect to each other and configured to be sequentially activated or sequentially deactivated to correspondingly indicate a real-time level of a fluid in the fluid tank. The indicia is disposed along the lighting units to correspondingly indicate at least one threshold level of the fluid in the fluid tank. The indicia allows inference of the real-time level to recede below the at least one threshold level if a sequential deactivation of the lighting units moves past the indicia in a first direction. In addition, the indicia allows inference of the real-time level to exceed the at least one threshold level if a sequential activation of the lighting units moves past the indicia in a second direction.
