Abstract: In view of the problems of low operation efficiency, short time and low degree of automation of mowing machinery faced by grass control management in agricultural production activities such as orchards and tea gardens in plateaus and hills in China, based on the selfdesigned intelligent hybrid lawn mower for hills and mountains, a lawn mower control system that can identify working conditions in real time and automatically complete energy management is designed. The system takes the driving condition identification signal received by the lawn mower in real time as the breakthrough point, adopts the realtime working condition identification algorithm program, and adopts the corresponding energy management control strategy according to the characteristics of different types of working conditions. The performance test of the control system is carried out by building the control system and combining with the working conditions. The test results show that the control system can quickly and accurately respond to the power and mowing performance requirements of the lawn mower, and its single operating time is approximately increased by 18%, compared with the hybrid lawn mower without energy management under the same fuel consumption. At the same time, the rationality of the working condition identification system is verified, and the accuracy of the correct identification duration of working conditions has reached more than 90%.
