Abstract: A loading calculation module includes a storage unit, an inertial sensing unit and a calculation unit. The first storage unit is configured to store a relationship between an engine performance and a load, a sprung mass, a centroid distance between a sprung centroid, a rotation center and a moment of inertia. The inertial sensing unit is configured to detect a tilt angle, a tilt angular velocity, a tilt angular acceleration and a lateral acceleration. The calculation unit is configured to obtain a load corresponding to the engine performance according to the relationship between the engine performance and the load; and obtain a load position according to the moment of inertia, the tilt angle, the tilt angular velocity, the tilt angular acceleration, the lateral acceleration, the load and the centroid distance.

Abstract: A navigation and positioning device including a storage, a mark feature analyzer, a first coordinate fusion component and a second coordinate fusion component is provided. The storage stores map information including a traffic mark feature and its mark coordinate. The mark feature analyzer is used for analyzing whether a captured image has the traffic mark feature. When the captured image has the traffic mark feature, the mark feature analyzer analyzes the traffic mark feature in the captured image and calculates a device coordinate according to the mark coordinate. The first coordinate fusion component fuses the device coordinate and a first fusion coordinate and uses fused coordinate as a second fusion coordinate. The second coordinate fusion component fuses the second fusion coordinate, traffic carrier inertial information and a global positioning coordinate and uses fused coordinate as an updated first fusion coordinate.
