Abstract: A system and method are provided for assisting a machine operator in controlling a work tool of the machine. In an embodiment, the work tool is set at a first height and the machine is travelling at a first machine speed, resulting in a first work tool or machine load. Based on these factors, a first work tool control mode or second work tool control mode is chosen. In the first work tool control mode, the work tool is manually controlled within a load limit and a work tool height limit, whereas in the second work tool control mode, the work tool load is controlled toward the first work tool load. Based on operator inputs and machine state, as well as other factors such as ground surface, the machine may switch between control modes, or out of automatic work tool control entirely.

Abstract: Embodiments of the present invention relate to powered vehicles (e.g., lawn mowers) and, more particularly, to a control system for use with such a vehicle. In one embodiment, the vehicle includes a power source such as an internal combustion engine and one or more drive control levers incrementally movable between a neutral position and a maximum velocity position. The system may also include a velocity profile control system having an adjustment member that permits altering a ratio between control lever movement and velocity of an associated drive member or wheel. Thus, the system may alter a maximum potential velocity of the vehicle while the drive control lever(s) are positioned in the maximum velocity position without varying an output level of the power source.
Abstract translation: 本发明的实施例涉及动力车辆（例如，割草机），更具体地，涉及一种用于这种车辆的控制系统。 在一个实施例中，车辆包括诸如内燃机的动力源和可在空档位置和最大速度位置之间递增移动的一个或多个驱动控制杆。 该系统还可以包括速度分布控制系统，其具有允许改变控制杆运动与相关联的驱动构件或车轮的速度之间的比率的调节构件。 因此，当驱动控制杆位于最大速度位置时，系统可以改变车辆的最大潜在速度，而不改变动力源的输出水平。

Abstract: A controller monitors groundspeed in an articulated machine and selectively disables an automatic articulation control function when the groundspeed is at or near zero. If there is an indication that an operator may not be aware that the automatic articulation control function is active by comparing when a on switch was activated compared to a machine power cycle or an operator not being present, the automatic articulation control function may be inactivated until the on switch is toggled. If the articulated machine is in neutral and the groundspeed is at or near zero, the automatic articulation control function may disabled. If the groundspeed is at or near zero but the transmission is not in neutral, the machine may simply be stalled to due working conditions and the automatic articulation control function may be maintained.
Abstract translation: 控制器监视铰接机器中的速度，并且当地面速度处于或接近零时选择性地禁用自动关节运动控制功能。 如果通过比较启动开关与机器电源周期相比或者不存在操作者的情况，操作者可能不知道自动关节控制功能是活动的指示，则可以将自动关节控制功能停用直到 开关切换。 如果铰接机器处于中立状态，并且速度处于或接近零，则可能会禁用自动关节运动控制功能。 如果地面速度为零或接近零但变速箱不处于空档状态，则机器可能会被简单地停止到适当的工作条件，并且可以保持自动关节运动控制功能。

Abstract: A skid steered light all terrain vehicle (LATV), including two driving units for the wheels or tracks on both sides of the vehicle and a differential steering device with a differential gear. The differential steering device is designed to produce a defined differential speed of the two drive units of the vehicle related to the steering angle of the steering device regardless to the surface condition where the vehicle is driving. The LATV also includes an additional steering drive acting on the differential gear.
