    摘要: A lane-keep control system is installed in a host vehicle equipped with an inter-vehicle distance control system. The lane-keep control system is arranged to decrease a threshold to be compared with the vehicle traveling condition for determining the tendency of the lane deviation when the inter-vehicle distance is being executed, so that the deviation avoidance control during execution of the inter-vehicle distance control is started earlier than the deviation avoidance control during inexecution of the inter-vehicle distance is started.

    摘要: A vehicle running condition judgment device for accurately detecting a change in a road surface condition and a vehicle's limit running condition. With substitution of respective tire characteristics and a detected state quantity into a vehicle motion model, vehicle slip angles are estimated for respective assumed road surface conditions. Based on the current state quantity and the last estimated vehicle slip angle, currently estimated vehicle slip angles for the respective assumed road surface conditions are compensated. A differential operation section calculates an estimation value of a vehicle slip angular velocity for each of the assumed road surface conditions based on the compensated vehicle slip angles for the respective assumed road surface conditions. Meanwhile, an operation section calculates a detection value of a vehicle slip angular velocity based on the detected state quantity. By comparing the detection value and the respective estimation values for the assumed road surface conditions, the current road surface condition is determined. Further, a lateral acceleration is calculated based on a vehicle slip angle, and compared with the detection value for determination of the road surface condition, and also with a predetermined limit value for determination of a vehicle's limit running condition.

    摘要: A control system is disclosed for controlling a power takeoff (PTO) shaft of a work vehicle (e.g., a tractor). The work vehicle includes an engine and an operator station, and the PTO shaft transfers power from the engine to an implement. The control system includes a remote switch, a vehicle speed sensor, and a control circuit. The remote switch is located remotely from the operator station and provides a remote switch signal to the control circuit to engage and disengage rotational movement of the PTO shaft. The vehicle speed sensor provides a vehicle speed signal to the control circuit representative of a speed of the work vehicle. The control circuit receives the remote switch signal and the vehicle speed signal and, when the vehicle speed signal exceeds a predetermined vehicle speed, the control circuit prevents engagement and disengagement of the PTO shaft with the remote switch.

    摘要: A dozing system for a bulldozer capable of providing high operational efficiency in dozing operation and a smooth excavation face. If it is determined when operation is performed in an automatic digging mode that the load exerted on the blade is stable, a target position for the cutting edge relative to the ground is corrected to the actual position of the cutting edge at that time. According to the ratio of the amount of excavated soil loaded on the front surface of the blade to the loading capacity of the blade front surface and/or the stability of the load exerted on the blade, a switching is performed between a weight characteristic for the operation amount of the load control and a weight characteristic for the operation amount of the smoothing control. Further, a map for correlating actual travel distance with the position of the blade cutting edge is prepared, and stable cutting edge positions are accumulated in each respective cycle and averaged to obtain an optimum target value for the smoothing control.

    摘要: A process for monitoring load conditions on a lifting machine having a rated load moment includes determining an actual load moment of the lifting machine due a weighted load. The actual load moment may be determined by measuring a tilt pressure within a hydraulic tilt cylinder of the lifting machine, and then calculating the actual load moment from the tilt pressure within the hydraulic tilt cylinder. The location of a center of gravity of the weighted load is also determined by measuring a lift pressure within a hydraulic lift cylinder of the lifting machine, and then calculating the weight of the weighted load from the lift pressure. Once the weight is determined, the location of the center of gravity of the weighted load may be found using the actual load moment and the calculated weight. Information about the weight and the location of the center of gravity of the weighted load may be also provided to a user as well as warnings if the operating parameters of the lifting machine are in danger of being exceeded or actually exceeded. If a load pressure switch of the lifting machine is activated, at the very least, the lifting function of the machine will be disabled.

    摘要: When operating a work machine having more than one function, there are situations in which an operator may need to simultaneously control both functions. For instance, when a backhoe loader operator would like to perform a maneuver referred to as the “duck walk”, the operator must simultaneously control at least one aspect of a backhoe and one aspect of a loader. A work machine that has an operator control station with at least two controllers, which may be assigned a first mode pattern, a second mode pattern, and a hybrid mode pattern. When the at least two controllers are in the first mode pattern, the at least two controllers are operably coupled to a first set of equipment, such as a loader. When the at least two controllers are in the second mode pattern, the at least two controllers are operably coupled to a second set of equipment, such as a backhoe. When the at least two controllers are in the hybrid mode pattern, the at least two controllers are simultaneously operably coupled to at least a portion of the first set of equipment (loader) and at least a portion of a second set of equipment (backhoe).
