1. A lawn mower control method, comprising:
detecting operating data and sensing data of a plurality of operating sensors provided on a lawn mower, wherein the plurality of operating sensors comprise at least two different types of sensors, the at least two different types of sensors comprise image sensors and position sensors, sensing data of the at least two different types of sensors is configured to obtain an information of obstacle;
fusing the sensing data of the plurality of operating sensors to obtain environment data around the lawn mower, the environment data comprises the information of obstacle;
determining, when it is detected that a fault occurs in any of the operating sensors, a fault type of a faulty sensor according to the operating data of the faulty sensor the environment data around the lawn mower, and a correspondence table corresponding to the faulty sensor, wherein the faulty sensor is an operating sensor in which a fault occurs, the correspondence table comprises a correspondence of various fault types with a range of parameters, the range of parameters comprising a range of operating data and a range of environment data; and
controlling, in response to the fault type of the faulty sensor is a first fault type, the faulty sensor to stop operating, and a backup sensor corresponding to the faulty sensor to start operating.
