Abstract: A rollover prevention system for a machine is disclosed. The rollover prevention system may include an inertial measurement unit (IMU) configured to detect a discharge event of a payload material from the machine and measure a body angle of the machine. The rollover prevention system may further include a controller in communication with the IMU. The controller may be configured to determine an angle of repose of the machine based on the detected discharge event and the measured body angle.

Abstract: A retarding unit in a vehicle is automatically controlled based on conditions including a current setting of the retarding control, downhill grade, speed, current gear, and impending gear change. With the retarder control set in the high position, when the vehicle is operating at a downhill angle greater than the low angle threshold and less than the high angle threshold, and the pending gear is a large step downshift, automatically setting a retarder level to a low retarder level. When the vehicle is operating on level ground and the pending gear is a large step downshift or the current gear is first or second gear, automatically setting the retarder level to off. When the vehicle is operating on flat ground and the deceleration is above a trigger level, automatically setting the retarder level to a low retarder level.

Abstract: Systems and methods for adaptive throttle filtering are disclosed. One method includes receiving vertical acceleration data indicative of a plurality of vertical accelerations of a machine, receiving first throttle pedal data indicative of a plurality of throttle pedal movements, determining a filter factor based at least on the vertical acceleration data, filtering the first throttle pedal data, based at least on the filter factor, to determine second throttle pedal data, and causing the second throttle pedal data to be transmitted to a controller to effectuate control of an operation of an engine.

Abstract: A hill brake system in a vehicle uses a controller to determine when a number of conditions, such as being stopped on an incline, are met and then automatically applies a braking force at least equal to a calculated grade load, that is, gravitational force. Using drive train measurements and known drivetrain characteristics, a rimpull force is calculated after release of an operator-controlled brake and the automatically applied braking force is reduced corresponding to the rimpull force generated by the drivetrain. The automatically applied braking force is released when any of several conditions are met including uphill motion of the vehicle or expiration of a timeout timer.
