The invention provides a curve active collision avoidance control method based on multi-sensor fusion. A vehicle-mounted vision sensor and a millimeter wave radar are utilized to realize double margin protection, and the vehicle-mounted vision sensor is used for detecting an angle of deviation of road obstacles and lane lines, the millimeter wave radar detects the obstacles in front, and the obstacle information in a trajectory is judged by a fusion algorithm. The collision time of the obstacles in a curve is calculated by combining the vehicle speed and the motion state information. According to different requirements, a corresponding active control strategy is given, and the vehicle active safety performance is improved; and meanwhile, the curve active collision avoidance control method does not require a driver to operate, the execution process is intelligent and efficient, and the stability is high.

The invention relates to a method for preparing a CuO@carbon cloth flexible electrode material through one step by regulating and controlling an interface cavitation effect. A carbon cloth matrix withdifferent gas infiltration states on the surface is obtained by regulating and controlling the infiltration method and time of carbon cloth in a polytetrafluoroethylene (PTFE) solution with a specific concentration; the CuO@carbon cloth electrode material with different interface structures is prepared by using a copper salt as raw material and ammonia water as a guiding agent, preparing a precursor solution, changing a carbon cloth fixing position and regulating and controlling aeration process conditions (aeration time, continuous or intermittent operation, simultaneous execution with ultrasonic application or not and gas flow rate). According to the method, the active control of the cavitation effect at the solid surface is realized by coordinatively regulating and controlling the gasinfiltration state of the solid surface and the aeration process conditions, and a CuO@carbon cloth electrode with controllable supporting capacity is obtained. The structural characteristics such asthe supporting capacity and distribution of CuO on the surface of the carbon cloth are changed, and the method has the advantages of being simple, high in efficiency, easy to carry out, controllable in CuO supporting capacity and the like and has great development potential.
