    摘要： Terrain-based machines are provided comprising a translational chassis movement indicator, a terrain-based implement, an implement inclinometer, and an implement state estimator. The translational chassis movement indicator provides a measurement indicative of movement of the machine chassis in one or more translational degrees of freedom. The implement inclinometer comprises (i) an implement accelerometer, which provides a measurement indicative of acceleration of the terrain-based implement in one or more translational or rotational degrees of freedom and (ii) an implement angular rate sensor, which provides a measurement of a rate at which the terrain-based implement is rotating in one or more degrees of rotational freedom. The implement state estimator generates an implement state estimate that is based at least partially on (i) implement position signals from an implement angular rate sensor and an implement accelerometer, and (ii) signals from the translational chassis movement indicator and the implement inclinometer.

    摘要： A tractor has hydraulically driven wheels at a cab end and castor wheels at an engine end. Each driven wheels is driven by a hydraulic motor with a continuous adjustment of the motor displacement, with the motor being driven by a pump also having continuous displacement. The motor displacement is controlled by an electronic controller in response to stroking of the speed control lever to manage the displacement to provide required drive torques at different points in the stroke. There is provided an automatic steering system having a guidance controller arranged to receive GPS position information which controls the steering by differentially adjusting the displacement of the motors so that the automatic steering is independent of the manual steering which controls the pumps.

    摘要： A four wheel drive system for bilaterally symmetric vehicles has separate controlled drive speed and direction for each wheel. Each drive system is operable to independently drive each wheel. The rear wheels of the vehicle are steering wheels which are connected with the vehicle frame for independent rotation about a vertical axis. Steering and driving of the wheels is controlled by a controller. The combination of controlled steering for the rear wheels through many degrees about their vertical axes and individual power to all four wheels provides the vehicle with a zero turning radius for improved mobility as well as improved traction on unstable surfaces.

    摘要： An electronic steering assembly is disclosed for a dual motor vehicle having a first and a second motor for driving a first and a second drive wheel. The electronic steering assembly comprises a handlebar rotatably mounted relative to a base. A sensor senses the rotational position of the handlebar relative to the base. A control is interposed between the sensor and the first and second motors for powering the first and second motors in accordance with the rotational position of the handlebars for steering the dual motor vehicle through the rotational movement of the handlebar.

    摘要： A transaxle (1), having a hydraulic drive unit (20) and a pair of left and right wheel support units (2L and 2R), is suspended from a vehicle frame so as to be turnable around a turning-center axis oriented in a fore-and-aft direction of a vehicle. The hydraulic drive unit (20) comprises: a pair of left and right hydraulic motors (23L and 23R) having respective left and right horizontal motor shafts (23b); a center section (22) formed therein with an oil passage for hydraulically connecting at least one of the hydraulic motors to a hydraulic pump, the center section having motor attachment surfaces onto which the hydraulic motors are attached; and a pair of left and right axle casings (2L and 2R) containing the respective hydraulic motors and supporting the respective motor shafts. The pair of wheel support units (30L and 30R), supporting respective left and right travel wheels (1L and 1R), are joined to respective outer ends of the left and right axle casings, and drivingly connected to the respective motor shafts (23b).
