The invention relates to the technical field of automobile fuel tank theft prevention, in particular to a fuel tank theft prevention system, a fuel tank theft prevention method and a fuel tank cap. The upper-layer structure of the cover body is provided with an accommodating cavity for accommodating the circuit board and the first detection module; the cover body lower layer structure is provided with an elastic sheet and a second detection module; the oil tank cover is tightly connected to an oil tank opening of the oil tank through the elastic piece. The sensor and the circuit are arranged in the fuel tank cover, system modification cost is avoided, and implementation is easy; the liquid level is directly measured through the ultrasonic sensor; multiple sensors are fused to monitor the fuel tank cap (upper and lower layers) and the fuel level state; the vehicle state is judged through the inertial sensor, other parts of the system are kept dormant in the driving state, system power consumption is reduced, and the service life of a battery is prolonged; the used sensors are all products which are adopted in a large scale in the fields of consumption and generic industry. Compared with the current mainstream scheme, the cost can be saved by 50-80%.

    本发明涉及汽车油箱防盗技术领域,具体而言涉及油箱防盗系统、油箱防盗方法以及油箱盖,包括盖体上层结构和盖体下层结构;所述盖体上层结构具有用于容纳电路板以及第一检测模块的容腔;所述盖体下层结构设有弹片以及第二检测模块;其中,油箱盖通过所述弹片紧连接到油箱的油箱口。本发明传感器及电路设置于油箱盖内,无系统改装成本,易于实现;通过超声波传感器直接测量液位;多传感器融合监控油箱盖(上、下层)及油位状态;通过惯性传感器判断车辆状态,行车状态下系统其它部分保持休眠,降低系统功耗延长电池使用寿命;所使用的传感器均为消费和泛工业领域大规模采用的产品。相比当前的主流方案,可以节省50‑80%的成本。
