A control system for a vehicle having a loader arm, such as a skid steer loader, telescopic handler, wheel loader, backhoe loader or forklift, reads a load height sensor, a load weight sensor; dynamically calculates the static center of gravity of the combined vehicle and load; calculates the acceleration necessary to cause the dynamic center of gravity of the combined vehicle and load to extend exterior of the vehicle's stability polygon; and limits the acceleration of the vehicle to less than the acceleration necessary to cause the dynamic center of gravity of the combined vehicle and load to extend exterior of the vehicle's stability polygon.

A backhoe loader 10 with a controller 100 that uses angular signals from at least one sensor to calculate a loader tool angle with respect to the vehicle frame 12 or with respect to the earth and to maintain the loader bucket angle via controller generated commands to a bucket actuator 60 as a function of the angular signals and commands to a boom actuator 60. The controller 100 enables proportional control of the tool angle via a command input device such as an electronic joystick 21. The controller 100 is capable of maintaining an inclination of the tool 36 with respect to the frame 12. If the boom 31 rises to an angle that is equal to or above a predetermined anti-spill boom angle the controller 100 drives the tool via commands to the tool actuator 60 to a tool angle that is equal to or less than a predetermined anti-spill bucket angle.

A backhoe loader with a controller that uses angular signals from at least one sensor to calculate a loader tool angle with respect to the vehicle frame or with respect to the earth and to maintain the loader tool angle via controller generated commands to a tool actuator as a function of the angular signals and commands to a boom actuator. The controller enables proportional control of the tool angle via a command input device such as an electronic joystick. If the electronic joystick is moved to an appropriate detent position, the controller executes a return to carry function.

Automatic and simultaneous retraction of a pair of stabilizer legs for a backhoe loader machine is beneficial for the operator (not shown). Instead of retracting the stabilizer legs by manually holding a pair of control levers continuously in a retract position, the operator (not shown) may simply move the control levers to an auto-retract position. The movement of the control levers in such a manner activates a control switch in connection with each of the control levers. The control switches, in turn, activate a timer relay that activates a solenoid detent operative with each control lever. Once the solenoid detents are in an activated state, the operator (not shown) may relinquish contact with the control levers. The solenoid detents will retain the control levers in the auto-retract position via electro-magnetic forces. The timer relay controls the solenoid detents so that the control levers are retained in the auto-retract position for a preselected time to fully retract the stabilizer legs from any one of a plurality of extended positions.

A backhoe loader 10 with a controller 100 that uses angular signals from at least one sensor to calculate a loader tool angle with respect to the vehicle frame 12 or with respect to the earth and to maintain the loader tool angle via controller generated commands to a tool actuator 60 as a function of the angular signals and commands to a boom actuator 50. The controller 100 enables proportional control of the tool angle via a command input device such as an electronic joystick 21. If the electronic joystick 21 is moved to an appropriate detent position, the controller 100 executes a return to dig function. If the bucket 31 is below the return to dig angle at the time the joystick 21 is moved to the detent position, the controller 100 generates commands to move the bucket 36 to the return to dig angle via a curling motion. If the bucket 31 is above the return to dig angle at the time the joystick 21 is moved to the detent position, the controller 100 generates commands to move the bucket 36 to the return to dig angle via a dumping motion. If either return to dig or a return to carry function while the other is being executed then the two are combined such that return to dig is completed prior to return to carry.

A backhoe loader 10 with a controller 100 that uses angular signals from at least one sensor to calculate a loader tool angle with respect to the vehicle frame 12 or with respect to the earth and to maintain the loader tool angle via controller generated commands to a tool actuator 61 as a function of the angular signals and commands to a boom actuator 50. The controller 100 enables proportional control of the tool angle via a command input device such as an electronic joystick 21. If the electronic joystick 21 is moved to an appropriate detent position, the controller executes a return to carry function. If the boom 31 is at or below the return to carry angle at the time the joystick 21 is moved to the detent position, the controller 100 executes a float function allowing the bucket 36 and the boom 31 to rest on the ground and follow the contours of the earth as the vehicle moves over the earth.

A method of reducing fuel consumption in a machine with an internal combustion engine. The machine has a hybrid mode in which the engine is used for simultaneous ground propulsion via a torque convertor and hydraulic implement propulsion via a hydraulic pump. The engine controller uses a first engine map that defines primary operating constraints. The method comprises: obtaining an initial torque limit from a torque limit profile providing operating constraints that fall within the primary operating constraints. The method further comprises: implementing a torque limit that corresponds to the initial torque limit value such that in an event that a torque demand exceeds the torque limit then the engine speed will drop below the desired engine speed. The method further comprises, in an event that torque converter speed ratio between engine and ground propulsion drops below a speed ratio threshold, removing the torque limit profile and reverting to primary operating constraints.
