An electrohydraulic steering system for machines includes manual steering and automatic steering (autopilot) modes which can be activated by a switch (3). The system has a hydraulic steering cylinder (6) for displacement of the steerable wheels, at least one sensor (7) for determining the wheel angle actual values (.delta..sub.w), at least one electrically operated hydraulic control valve (5) which regulates admission of hydraulic fluid to the steering cylinder (6) and at least one automatic steering signal transmitter (2) for generating electrical steering signal nominal values (.delta..sub.s2) for the wheel angles. An electronic control and analysis device (4) is fed the automatically generated steering signal nominal values (.delta..sub.s2) and the wheel angle actual values (.delta..sub.w). The control and analysis device (4) determines an electrical trigger signal (4S) for the hydraulic control valve (5) from the wheel angle actual value (.delta..sub.w) and the automatically generated steering signal nominal value (.delta..sub.s2) . A steering signal transmitter (1) is provided for the manual steering, which from a manual steering movement generates a corresponding electrical steering signal nominal value (.delta..sub.s1) which is also fed to the control and analysis device (4). Depending on which steering mode is active, the control and analysis device (4) analyses the manual or automatic steering signal nominal values.

A tandem running gear on a self-propelled agricultural machine, in particular a combine, where in the front a drive axle (1) and on both sides thereof swing arms (3, 3A) are disposed under the chassis (2). The swing arms (3, 3A) can be charged by hydraulic work cylinders (8, 8A) in such a way that a respectively preset wheel load distribution between the drive wheels (5, 5A; 6, 6A) and the steered wheels (7, 7A) is attained using a measuring and control device for the hydraulic device.

A circuit arrangement consisting of a computer processor from which a connecting bus extends and a circuit board is connected to a bus which carries switching amplifiers the outputs of which are connected via peripheral connector contacts to load circuits is shown. Threshold discriminator circuits and analog signal amplifiers are connected to the connector contacts, and the bus output signals are fed via the connecting bus the processor. The working of the load circuits and further attached signals are evaluated by the processor.

A harvesting system includes a self-propelled harvesting machine and a drivable collecting container equipped with a drive unit, which can be positioned relative to the harvesting machine and moved in parallel therewith. Crop is fed directly or indirectly to the collecting container during harvesting operation from the harvesting machine using a feed pipe equipped with an outlet chute. The collecting container is equipped with a device for loading it with crop in a uniform manner. The collecting container is moved in a constant position relative to the harvesting machine by way of a control device while the crop is being conveyed. The collecting container is preferably a filling device, by way of which uniform distribution of the crop in the collecting container (8) can be attained.

A measuring device for measuring components of a crop material is installed on an agricultural machine and includes at least one conductance sensor, determining the component “moisture content”, which is determined via the temperature-compensated detection of conductance. In this manner it is ensured that the measuring device delivers reliable measurement results for determining the components of a crop material even under fluctuating measuring conditions.
摘要:
An agricultural working vehicle has a plurality of working assemblies, at least one control unit for influencing the setting parameters of the working assemblies, a memory unit, and at least one display unit, and it is configured such that even an untrained operator may optimize the setting parameters of the working assemblies in a rapid, reliable manner. An expected change in the function and/or the working result of individual working assemblies or a plurality of working assemblies is depicted in the display unit in a manner that depends on how an operator influences individual setting parameters of the working assemblies.
摘要:
For controlling several agricultural machine systems during operation on a territory, based on a reference line, an optimized route for working the territory is determined for the particular machine system, and the particular machine system is driven along this route. The reference line is determined by recording a reference path that was driven along with a first machine system, and the first machine system is controlled based on this reference line with consideration for the working conditions of the first machine system. This reference line is also transmitted by the first machine system to at least one second machine system, which is controlled based on this reference line of the first machine system and with consideration for the working conditions of the second machine system. A corresponding control system for controlling several agricultural machine systems during operation of a territory is also described.

摘要:
Vehicles, in particular self-propelled agricultural harvesting machines such as forage harvesters or combine harvesters designed to pick up and process crops, include transfer devices that transfer all of the harvested crop material to a hauling vehicle or an attached hauling container. The discharge device is equipped with a control device for performing automatic or manual adjustments, and the self-propelled agricultural harvesting machine is equipped with a navigation system for determining the positions of the vehicles involved. To transfer the crop material to the hauling vehicle without loss, the crop discharge flow is directed only to a defined permissible tolerance region on the hauling container. The tolerance region is located within the hauling container contour and is bounded by edge zones, which are “keep-out” zones for the transfer.

A device for coordinating a machine fleet includes a memory for storing a large number of data records, an interface for communicating with several users who are capable of making changes to the data records, in the case of which each data record represents a given portion of the working capacity of a machine in the machine fleet, and the changes relate to the assignment of the portion of the working capacity represented by the data record to the users making the change, and an administration unit designed to allow a change to be made to a data record by a user requesting the change if the data record is not assigned to any other user and an urgency of the change indicated by the requesting user reaches a threshold specified for the particular portion.
