There are provided an engine controlling section for controlling a rotational speed of an engine, a horizontal posture controlling section for rendering a vehicle body frame to a horizontal posture by controlling a posture changing mechanism configured to change a posture of the vehicle body frame by an operation of an actuator utilizing power from the engine, a yield measuring section for measuring a yield of grains stored in a grain tank based on measurement result of a load cell configured to measure a weight of the grain tank, an activation operational tool for outputting an activation signal for activating yield measurement by the yield measuring section, and a yield controlling section configured to provide the engine controlling section with a high speed rotation instruction for driving the engine at a rated rotational speed in response to the activation signal and also to provide the horizontal posture controlling section with a horizontal posture instruction for rendering the vehicle body frame to the horizontal posture.

A method for determining an axle load and a suspension system are configured for a vehicle having at least one leaf spring connected at its ends in spring holders of a vehicle body and connected in its central region to a chassis of the vehicle. The following steps are performed: measuring a measurement distance of the vehicle body relative to the chassis; determining whether there is currently a loading or unloading process of the vehicle, determining a relevant hysteresis curve of a pre-stored hysteresis field depending on the determination of a loading or unloading process, and determining a current axle load projection value from the measurement distance and the relevant hysteresis curve. A loading process criterion and an unloading process criterion may be considered. The determined axle load projection value thus serves as a projected or estimated axle load. Furthermore, the hysteresis field can be updated.

A vehicle is provided that includes a body defining a roof. A roof rack is operably coupled to the roof through a plurality of mounting features and configured to support cargo. A load cell is positioned on each of the mounting features and configured to sense a load on the roof rack associated with the cargo. A controller is in communication with the load cells and an electronic device and a light source is positioned proximate each of the mounting features. The light source is configured to emit light based on the load sensed by the load cell.

Systems and methods for calibrating an onboard vehicle scale may include disposing a vehicle upon a reference scale; determining reference weight information corresponding to a weight of at least a portion of the vehicle using the reference scale; automatically and wirelessly communicating the reference weight information to an onboard scale coupled to the vehicle; and automatically calibrating the onboard scale using the reference weight information.

A cast load cell comprising a load sensing portion integrally cast with a first mounting portion. The load sensing portion has a flexure portion spaced apart from the first mounting portion by a flexure gap. The load sensing portion has at least one sensor cavity above at least a portion of the flexure gap. A second mounting portion is integrally cast with the load sensing portion above the flexure gap. A load sensor is connected to the load sensor portion and positioned within the sensor cavity above a portion of the flexure gap. The first mounting portion, the load sensing portion, and the second mounting portion define an integral, low-profile, weld-free, substantially homogenous unitary cast member.
