摘要： A method at a sensor apparatus affixed to a transportation asset. The method includes calibrating the sensor apparatus by initiating a vertical impact at the transportation asset, measuring spring oscillation and creating a model of the transportation asset. The method further includes detecting, subsequent to the calibrating, an impact event at the sensor apparatus. The method further includes measuring spring oscillation due to the impact event at the sensor apparatus and using the measured spring oscillation in the model created during calibration to create a load mass estimate for the transportation asset.

摘要： A vehicle having powered door assist includes a plurality of powered doors, each powered door having an actuator for moving the door between closed and open door positions, and a plurality of sensors located on the vehicle for sensing objects proximate to the vehicle including one or more potential passengers expected to enter the vehicle and for sensing an obstacle within or proximate to a swing path of at least one of the plurality of powered doors. The vehicle also includes a controller determining an estimated weight of the one or more potential passengers, detecting expected height of the plurality of powered door with the estimated weight added to the vehicle, detecting height of a sensed obstacle within the swing path of one of the powered doors and determining whether the expected height of the one powered door will interfere with the sensed obstacle in the swing path.

摘要： A method for determining the payload mass resting on a wheel of a vehicle. In the method: using a level sensor system, in a time period in which the vehicle is moved, a time series of measured values is detected, which each indicate the vertical position of the vehicle body in relation to the wheel; a model is provided for the temporal development of the vertical position under the influence of the gravitational force of vehicle body and payload, an elastic suspension between the vehicle body and the wheel of the vehicle, and a damping of the vertical relative movement between the vehicle body and the wheel of the vehicle, the model being parameterized at least using the sought payload mass and the wheel of the vehicle and the connection of the wheel to the roadway being assumed to be rigid.

摘要： A method for estimating load weights for a work vehicle including a boom pivotably coupled to the chassis of the work vehicle at a boom joint and an implement pivotably coupled to the boom at an implement joint may include receiving an input indicative of a tilt force associated with a tilt cylinder configured to pivot the implement about the implement joint, and an input indicative of a lift force associated with a lift cylinder configured to pivot the boom about the boom joint. The method may further include determining a torque about the implement joint caused by the load based on the tilt force and determining a torque about the boom joint caused by the load based on the lift and tilt forces. Additionally, the method may include estimating a weight of the load based on the torques about the boom and implement joints.

摘要： A method for estimating a level of stress that a mine truck is subjected to. The mine truck includes a frame; a container for carrying payload supported by the frame; and at least one sensor, the at least one sensor delivering signals being dependent on a force acting on the mine truck. The method includes for at least a first position of the frame, estimating a level of stress that said at least a first position is subjected to in response to a force acting on the mine truck, wherein said at least a first position is a position being different from the position of said at least one sensor; and estimating said level of stress utilising a model representation of the level of stress for said at least a first position wherein said model representation output said estimated level of stress utilising sensor signals from said at least one sensor as input signals.

摘要： A system and a method for remote operation of a working machine comprising a tool is provided. The system includes an on-board controller configured to receive signals from a remote control station remotely controlling the operation of the working machine, and to obtain and send camera images to an off-board controller. The system also includes an off-board controller configured to receive the camera images from the on-board controller. The off-board controller identifies at least one visual tag in the camera images located on a load carrier, determines at least one distance between the tool and the load carrier based on the identified at least one visual tag, and provides, to the on-board controller and/or to an operator of the working machine, information based on the determined at least one distance between the tool and the load carrier in order to support the remote operation of the working machine.

摘要： A load weight notification device includes a weight sensor configured to detect a load weight of a vehicle as a detection weight, an output device configured to at least notify a passenger in the vehicle of information, and a controller configured to, in a case where the detection weight obtained during an opening period of a door of the vehicle exceeds a prescribed first threshold value, instruct the output device to notify the passenger of information indicating overweight, in which the controller is configured to, until completion of an initial closing operation that is a closing operation of the door performed after the vehicle is activated until the vehicle starts traveling, not instruct the output device to notify the passenger in the vehicle of the information indicating the overweight even when the detection weight exceeds the first threshold value.
