Abstract: A track for a track vehicle has sensor-receiving cavities disposed therein. Removeable sensors are placed in the sensor-receiving cavities for sensing characteristics of the track during operation.

Abstract: A traction subsystem on a track vehicle has a first roller and a second roller. The first roller rotates either with an axle, or about an axle, and rotatably supports a track in opposition to a surface over which the track is traveling. A sensor is disposed relative to the first roller so that, as the first roller rotates, the sensor moves through a load bearing position in which the sensor is positioned between the axle and the track, bearing at least a portion of a load imposed by the track vehicle. The sensor illustratively senses pressure on the track, when in the load bearing position.

Abstract: A mobile agricultural machine includes a steering system configured to steer the mobile agricultural machine. At least one distance sensor is mounted on the mobile agricultural machine and is configured to provide a distance sensor signal indicative of a distance from the mobile agricultural machine to a surface of a remote object. A controller is operably coupled to the steering system and the at least one distance sensor. The controller is configured to receive an operator input enabling object detection and responsively monitor the distance sensor signal of the at least one distance sensor to detect a linear object surface and to responsively generate a steering output to the steering system to maintain a prescribed lateral distance from the detected linear object surface.

Abstract: A control system and method is provided for a vehicle. The control system includes a speed sensor, a wheel angle sensor, and a vehicle position sensor. An electronic control unit (ECU) determines a yaw-rate error as a function of at least the vehicle position signal, determines a first speed limit as a function of the yaw-rate error, determines a second speed limit as a function of a vehicle lateral acceleration, and determines a third speed limit as a function of the wheel angle signal. The ECU selects the lowest of the first, second and third speed limits, generates a front wheel drive command and a diff lock command as a function of the wheel angle signal. The ECU also limits the vehicle speed to not greater than the selected lowest wheel speed limit.

Abstract: A guidance method and system automatically steers a guided vehicle which moves along a planned path between adjacent crop rows. The vehicle has a frame and steerable wheels. The method includes generating a left crop position signal with a left crop sensor on a left side of the vehicle, generating a right crop position signal with a right crop sensor on a right side of the vehicle, and generating a vehicle position signal with a vehicle position sensor unit. The method also includes generating a difference position signal by subtracting one of the left and right crop position signals from the other of the left and right crop position signals, and converting the difference position signal into a time-varying lateral offset signal. The method also includes offsetting the planned path by the time-varying lateral offset signal, and guiding the vehicle as a function of the offset planned path.

Abstract: A method of controlling an engine and a transmission coupled to the engine. The method including the steps of receiving and proceeding. The receiving step receives a signal value from a sensor. The signal value is representative of a desired ground engaging device speed of a vehicle. The proceeding step proceeds along a shift path defined by a one-to-one correspondence between the signal value and the ground engaging device speed. The proceeding step includes the steps of controlling a speed of the engine and selecting of a gear of the transmission along the shift path dependent upon the signal value.

Abstract: A method for determining relative spatial information between a first vehicle and a second vehicle, the method including monitoring a communication channel at the first vehicle and receiving a current communication signal sent by the second vehicle on the communication channel. The current communication signal is received at a received power level. A relative position between the first vehicle and the second vehicle is calculated. Input to the calculating includes an actual or estimated transmitted power level, and the received power level.

Abstract: A communications system that includes techniques for protecting the transmission of data and information between vehicles so as to prevent a second automakers from using information developed by a first automaker. The communications system employs a layered protocol network. Sensors on the vehicle provide various information, some of which is sent to each layer in a network protocol and some of which may be broadcast. One or more encrypting algorithms is provided at suitable locations in the protocol, such as between the various layers or at the output of the sensors, that prevents data from being used by the second automaker's vehicle transmitted from the first automaker's vehicle who does not include a decryption algorithm to decrypt the information.

Abstract: A method for vehicle-to-vehicle communication. The method includes receiving data about a first vehicle and a second vehicle within a proximity of an intermediate node, where the receiving is at the intermediate node. The first vehicle is notified about the presence of the second vehicle and/or the second vehicle is notified about the presence of the first vehicle in response to the receiving.
