The application provides a load change-based demand torque control method, system and vehicle, and the method is as follows: (1) when the vehicle is in a stationary state, the actual load mass of the vehicle is read, and the load rate lambda corresponding to the current actual load mass is calculated; (2) the demand torque MAP under the current load rate lambda is extracted, and after the vehicle is in a running state, the demand torque MAP under the current load rate is used to determine the demand torque of the vehicle. When the change of the load rate is detected, the demand torque MAP is adaptively adjusted, so that the excessive acceleration or power deficiency caused by the change of the load is avoided, the energy utilization is optimized, and the power response more in line with the expectation of the driver is provided, especially when the change of the load is large (such as after sudden unloading).

This invention relates to the field of medical device technology, specifically to a notching device based on a paper-cut structure, comprising a stress-relieving sleeve and a catheter hub, as well as a pusher section, a metal tube, and a hollow head. The right end of the stress-relieving sleeve is connected to the catheter hub, and the left end of the stress-relieving sleeve is fitted with the pusher section. The other end of the pusher section is connected to the metal tube, which is coaxially connected. A PTA balloon passes through the catheter hub, the stress-relieving sleeve, and the pusher section, and the PTA balloon passes through the pusher section into the metal tube. The PTA balloon is nested inside the metal tube, and the end of the metal tube is connected to a bullet-shaped hollow head. When the PTA balloon is inflated, the surface of the cut metal tube begins to expand. When the surface of the metal tube expands to a certain extent, the expansion process cannot continue due to the limitation of the rhomboid angle. At this time, the force of the continued expansion of the PTA balloon causes the node of the cut section to rotate together with the connecting rod. The rotated connecting rod can apply circumferential force to the narrowed part of the blood vessel.

The invention provides a remote sensing image non-uniform defogging method and system based on wavelet guidance. The method comprises the following steps: performing wavelet transform on a remote sensing haze image based on a physical model of haze imaging, and decomposing the image into a low-frequency illumination component and a high-frequency texture component; taking the clear image and the medium transmissivity as optimization variables, constructing an energy function containing physical consistency constraint and multi-priori constraint, and carrying out joint solution on the low-frequency illumination component by adopting an alternate optimization mode; meanwhile, detail enhancement processing is carried out on the high-frequency texture component; and finally, performing reconstruction fusion on the optimized low-frequency illumination component and the enhanced high-frequency texture component to obtain a defogged remote sensing image. Correspondingly, the invention also provides a remote sensing image non-uniform defogging system for realizing the method. According to the technical scheme, the brightness distribution and detail performance of the remote sensing image can be effectively improved under the non-uniform haze condition, and the stability and visual quality of the defogging result are improved.
