Disclosed here are methods and systems for automatically operating automated vehicles moving through vegetation obstacles with minimal damage, comprising receiving image(s) depicting vegetation obstacle(s) blocking at least partially a path of an automated vehicle executing a mission, analyzing the image(s) to extract one or more obstacle attributes of the vegetation obstacle(s), computing a plurality of movement patterns for operating the automated to cross the vegetation obstacle(s) based on one or more vehicle attributes of the automated vehicle with respect to one or more of the obstacle attributes where each movement pattern defines one or more movement parameters of the automated vehicle, selecting one of the movement patterns estimated to reduce a cost of damage to the automated vehicle and/or to the one or more vegetation obstacles, and outputting instructions for operating the automated vehicle to move through the vegetation obstacle(s) according to the selected movement pattern.

A system and method of capacitance management in an agricultural vehicle and connected implement, wherein the vehicle and implement have a plurality of electric drives connected to a common connection and connectable to a direct current supply, and each electric drive has an associated Y capacitor between each direct current supply connection and the common connection, wherein the method includes receiving and summing capacitance values for each of the electric drives and comparing with a stored threshold value. If the threshold value is exceeded, a sequence of selective disconnections of individual electric drives is performed until the sum of the received capacitance values is less than or equal to the threshold value. The method may be performed manually, or automatically based on a sequence defined in a priority list until the sum of the received capacitance values is less than or equal to the threshold value.

A grounds maintenance system comprising: a robot tractor comprising; a robot body; a drive system including one or more motorized drive wheels to propel the robot body; a control system coupled to the drive system, the control system configurable to store a mow plan that specifies a set of paths to be traversed for a grounds maintenance operation and control the drive system to autonomously traverse the set of paths to implement the mow plan; a battery system comprising one or more batteries housed in the robot body; and a low-profile mowing deck coupled to the robot body, the mowing deck adapted to tilt and lift relative to the robot body, wherein the control system is configured to control tilting and lifting of the mowing deck and cutting by the mowing deck.

An off-road vehicle includes a driveline, a control system, and a braking system. The driveline provides driveline power and driveline brake power to a first tractive assembly and/or a second tractive assembly. The control system stores vehicle information, determines driving instructions based on environment data, and determines speed references for tractive elements of the first and second tractive assemblies based on the driving instructions and the vehicle information. The braking system includes brakes and a braking subsystem. The brake subsystem operates the brakes to provide brake power to one or more components of the first and/or second tractive assemblies. The brake controller controls the brakes to selectively provide the brake power and the control system controls the driveline to selectively provide the driveline power and the driveline brake power based on current speeds of the tractive elements and the speed references to accommodate the driving instructions.

A work vehicle and energy storage device include a ballast providing ballast weight to the horizontal end of the work vehicle, a stator of an electric machine having a vertically extending axis, a rotor of the electric machine fixed for rotation with the ballast and configured for rotation about the vertically extending axis, and a bearing supporting the ballast weight and the rotor for rotation of the rotor relative to the stator.

A work vehicle capable of traveling on a public road and in a working field includes: a public road traveling determination unit configured to generate vehicle body position information regarding a position at which the vehicle body is located, determine based on the vehicle body position information whether or not the vehicle body is traveling on the public road, and output a determination result; and a vehicle speed limiter configured to limit a vehicle speed in accordance with the determination result.
