    摘要: A fail-safe system and method for an electro-hydraulic system. The system includes a controller, sensor, directional control valve, interlock, hydraulic valve and movement actuator. The directional control valve moves when the controller is moved. The interlock is hydraulically coupled to the directional control valve; and is in active position when the directional control valve is moved, and in shutoff position when the directional control valve is not moved. The hydraulic valve has an input side coupled to a flow source and an output side coupled to a hydraulic function. The movement actuator moves the hydraulic valve to a desired position as directed by the controller when the interlock is in the active position, and does not move the hydraulic valve when the interlock is in the shutoff position. The sensor detects movement of the controller and sends a control signal to the first valve actuator.

    摘要: A method and system for controlling a vehicle comprises a torque detector for detecting a first torque level and a second torque level applied to at least one wheel of the vehicle. The first torque level is associated with a lower boom position of a boom and a second torque level is associated with an elevated boom position higher than the lower boom position. A first hydraulic cylinder is capable of raising a boom from the lower boom position to raise an available torque from the first torque level. A second hydraulic cylinder is adapted to upwardly rotate or curl a bucket associated with the vehicle when the detected second torque level meets or exceeds a second torque threshold, for example.
