Problems solved by technology

[0003] Mowing grass along a straight line is a common and efficient mowing method. It can basically achieve full coverage and no mowing blind spots on flat ground. However, on complex terrain such as slopes and hills, smart mowers can 1. The relationship between the deflection of the front wheel universal wheel, when encountering a grass slope, a landslide occurs, causing the self to deviate from the original route, entering a new route and unable to return to the original route, resulting in a mowing blind spot

Abstract

The invention relates to the technical field of lawn mowers, and particularly discloses a slope driving control method and system of an intelligent lawn mower. When the intelligent lawn mower slides on a slope and deviates from an original route, the optimal driving route can be planned in real time, the deviating intelligent lawn mower can optimally drive back to the original route, the problem that the intelligent lawn mower mows grass in repeated routes in a multi-slope section due to slope factors is solved, the lawn mowing coverage is greatly improved, and the lawn mowing blind area is basically prevented. According to the slope driving control system, by means of a high-reliability three-axis acceleration sensor, a three-axis angular speed sensor and a high-precision MCU control module, the intelligent lawn mower is more sensitive in reaction, more precise in mowing and higher in intelligent degree, the adaptability of the intelligent lawn mower to the complex working environment can be greatly improved, and the application range of the intelligent lawn mower is widened.

Description

technical field [0001] The invention relates to the technical field of lawnmowers, in particular to a slope driving control method and system for an intelligent lawnmower. Background technique [0002] With the rapid development of society's intelligence, people's demand for automatic maintenance of lawns is increasing. Manual lawn mowers can no longer meet the requirements of the era of high efficiency and strong controllability. In this situation, intelligent lawn mowers are constantly being used. Improve. Most of today's intelligent lawn mowers use electrical control for the rear wheels and a support structure for the front wheels that use universal wheels. The forward, backward, and turning actions during driving mainly rely on the left and right motors of the rear wheels of the intelligent lawn mower. This intelligent lawn mower is mainly used to perform straight-line mowing tasks on flat lawns without small obstacles. The PWM (pulse width modulation, the pulse width ...
