Methods and systems for estimating an axle load of a vehicle are described. In one example, a method is disclosed wherein axle load is estimated in response to an angle between two components of an axle. The angle may change as weight is added to or removed from the axle such that axle load may be determined as a function of the angle.

Disclosed is a load detection device and method using the same. In one example, the device includes a height-level measuring unit configured to determine a height level of a vehicle and to generate at least one height-level signal that characterizes the height level. A position-measuring unit is configured to determine the position of the vehicle relative to the mid-point of the earth and to generate at least one position signal that characterizes the vehicle position. An evaluation unit is coupled to the height-level measuring unit and to the position-measuring unit. The evaluation unit is configured to determine a mass of a load of the vehicle, taking into account the height-level signal(s) and the position signal(s). The device can be used to determine the mass of the load, which may include a number of persons.

A load in a bucket is accurately weighed. A work machine includes a work implement, an input receiving unit, and a controller. The work implement includes a bucket. The input receiving unit receives a weighing start input for starting to weigh the load in the bucket. When the input receiving unit receives the weighing start input, the controller determines whether an automatic weighing start condition is satisfied or not. The automatic weighing start condition includes a condition that the work implement is not performing an excavation work. When the automatic weighing start condition is satisfied, the controller controls an operation of the work implement to weigh the load in the bucket.

A system and method are provided for real-time deduction of material carryback in a loading container of a transport vehicle, wherein the material is loaded in the loading container by a work machine at a first site and dumped from the loading container by the transport vehicle at a second site. A first sensor (e.g., a camera associated with the work machine) provides first data corresponding to a volume of material loaded in the loading container in a first work state (e.g., loaded). A second sensor (e.g., a camera or a payload measuring unit associated with the transport vehicle) provides second data corresponding to a volume of material loaded in the loading container in a second work state (e.g., unloaded). A generated output signal corresponds to a calculated total volume of material associated with a work cycle, said total volume based on at least the provided first and second data.

A method for locating the position of each wheelset of a motor vehicle. Each wheelset including at least one wheel equipped with an electronic unit including at least one sensor to measure, for the wheel, the extent of the contact patch via which the tire is in contact with the ground, and a transmitter transmitting data regarding the extent of the tire contact patch to a control unit. The motor vehicle includes a load sensor for each of the wheelsets that measures and delivers to the control unit a value for the load supported by the associated wheelset. The method employing, on the one hand, data originating from a sensor able to determine the extent of the contact patch via which a tire is in contact with the ground and, on the other hand, a load sensor able to measure the load supported by a wheelset of the motor vehicle.
