Abstract:
An agricultural machine with an implement for working a row culture of working rows arranged parallel to one another, interference rows arranged at an angle to the working rows or both includes at least one controllably moveably working section with activatable working devices for working the row culture. The implement has a control unit for controlling the working section and working device relative to a working row and an optical sensor unit connected to the control unit for generating an image of at least part of the row culture, from which a sensor signal (S) is generated for controlling the controllably working section, working device or both. The control unit evaluates a validity of the sensor signal (S) to determine whether the sensor signal (S) is used for controlling the working section or working device based on at least one evaluation parameter.
Abstract:
A control system includes: a control valve control unit that controls a control valve; a data acquisition unit that acquires data on an operation command value and a cylinder speed in a state where an operation command for operating a hydraulic cylinder is output; and a deriving unit that derives operation characteristics in an operation direction of each of a plurality of hydraulic cylinders in relation to the operation command value based on the data acquired by the data acquisition unit. In acquisition of the data by the data acquisition unit, the control valve control unit controls a control valve of one pilot oil passage that is an acquisition object where the data is acquired among the plurality of pilot oil passages to open one pilot oil passage and controls control valves of the other pilot oil passages to close the other pilot oil passages.
Abstract:
A multiple-input multiple-output (MIMO) computer control system in a heavy equipment machine is in communication with multiple sensors in order to measure deviations from a path to be followed. Sensor corrections are applied to return the heavy equipment machine to a path to be followed or to restrain the machine from deviating from the path to be followed. Sensor corrections affect a controlled variable, such as cross-slope. Sensor corrections may account for false positives and false negatives. Sensor corrections are applied to the heavy equipment machine using a gain matrix (G). The multiple vectors of gain values comprising the gain matrix (G) are utilized by the MIMO computer control system to simultaneously and proportionally actuate each drive leg of the machine to obtain a desired grade including a compensated slope and/or elevation.
Abstract:
When a pedestrian or the like in an area that is ahead in the direction of movement of a vehicle travelling on a road and is adjacent to the road is moving in an direction to cross the road, a system ECU varies the time of execution of a safety operation for ensuring the safety of the pedestrian in accordance with a road condition in the area where the pedestrian or the like is present. Specifically, the time of execution of the safety operation is delayed in the order of a first road condition, in which the area in which the pedestrian is present is not in a roadway, a second road condition, in which the area is in a roadway and not in an opposing traffic lane, and a third road condition, in which the area is in a roadway and in an opposing traffic lane.

One embodiment describes a seed metering system that includes a first seed meter that controls seed deposition by a first row unit on a seed planting implement; a first direct vacuum source fluidly coupled to the first seed meter, in which the first direct vacuum source supplies vacuum pressure only to the first seed meter to enable the first seed meter to control seed deposition by the first row unit; a second seed meter that controls seed deposition by a second row unit on the seed planting implement; a second direct vacuum source fluidly coupled to the second seed meter, wherein the second direct vacuum source supplies vacuum pressure only to the second seed meter to enable the second seed meter to control seed deposition by the second row unit; and a control unit communicatively coupled to the first direct vacuum source and the second direct vacuum source, in which the control unit controls vacuum pressure supplied by the first direct vacuum source and the second direct vacuum source independently.
Abstract:
A driver assistance system of a vehicle for controlling a distance from the vehicle to a further vehicle. In the method, a distance between the vehicle and the further vehicle and a relative speed between the vehicle and the further vehicle are determined. When the vehicle approaches the further vehicle, the vehicle is operated in an operational state from a group of a plurality of predetermined operational states in dependence upon the distance and the relative speed.
Abstract:
The invention relates to a method for operating a flap arrangement of a motor vehicle, wherein the flap arrangement has a flap wing and a control arrangement, wherein a flap drive which is assigned to the flap wing and by which the flap wing can be adjusted between a closed position and an open position in an adjustment process is provided, wherein at least one predetermined flap operator control event is detected by means of the control arrangement and the flap drive is actuated as a technical control reaction to a flap operator control event. It is proposed that by means of the control arrangement the technical control reaction of stopping or continuing an adjustment process, which is due to two successive flap operator control events, is suppressed if at least one suppression condition is detected.

Abstract:
A collision avoidance ECU sets a model deceleration change amount to smaller value in a state in which it is difficult to reduce the speed of a host vehicle than in a state in which it is easy to reduce the speed of the host vehicle. The collision avoidance ECU calculates a first target value by multiplying the model deceleration change amount by the elapsed time. The collision avoidance ECU obtains a subtraction value by subtracting the current reference relative deceleration from the first target value. Then, the collision avoidance ECU determines a target relative deceleration to be a greater value when the subtraction value is large than when the subtraction value is small, and carries out brake control so that the reference relative deceleration approaches the target relative deceleration.
Abstract:
A remote user can define one or more zone based driver/vehicle behavior definitions. Current vehicle location is analyzed at the vehicle or remotely to determine if the vehicle is approaching or has arrived at a location for which a zone based driver/vehicle behavior has been defined. For zone based driver behavior definitions, a display in the vehicle automatically displays the zone based driver behavior definition to the driver. In some embodiments driver compliance is tracked and non-compliance is reported to the remote user. For zone based vehicle behavior definitions, a vehicle controller at the vehicle responsible for controlling the defined behavior is reprogrammed to impose the defined behavior (no regeneration at location, max speed at location, no idle over 2 minutes at location, etc.). Once the vehicle has left the zone, the controller programming reverts to its prior state, and/or zone based driver behavior definition is no longer displayed.
