System and method for power generation and information feedback based on tire deformation

Abstract

The invention relates to a system and a method for power generation and information feedback based on tire deformation, and the system is characterized in that a power generation element and a sensing element, which are made of PVDF piezoelectric films, are arranged in a tire, namely a first PVDF piezoelectric film (for power generation) and a second PVDF piezoelectric film (for sensing); the second PVDF piezoelectric film can timely and accurately sense the interaction between the wheel and the ground, directly collects the road environment information, is small in error and high in real-time performance, and solves the problem that the road environment information cannot be obtained; the first PVDF piezoelectric film and the power management chip can effectively convert tire deformation energy into electric energy, so that the energy utilization rate is improved, a single-chip microcomputer is used for supplying power, the maintenance cost is reduced, meanwhile, the PVDF piezoelectric films are used for a power generation element and a sensing element, and the integration level is high; the single-chip microcomputer can feed back road surface environment data to the whole vehicle control unit in time and remind the whole vehicle control unit in time when the road surface changes, so that the whole vehicle control unit changes a control strategy in time, and the driving safety of the vehicle is improved.

Description

technical field [0001] The invention belongs to the technical field of sensing systems, and in particular relates to a system and method for power generation and information feedback based on tire deformation. Background technique [0002] In recent years, the electrification, intelligence, networking, and sharing of automobiles have become a major trend in the development of the global automobile industry. The planning and control of vehicles have been continuously optimized and upgraded. demanding. At the same time, the global environmental problems are becoming more and more serious, and the demand for energy is increasing. As a pillar industry of the global industry, the automobile industry consumes a lot of energy. It is urgent to gradually improve energy utilization and reduce energy consumption. [0003] The collection of automotive environmental data on the market today mainly focuses on the perception and collection of obstacles, lane lines, traffic signals, and p...
