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.

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.
