Problems solved by technology

[0005] 1. Adding a steering mechanism to the existing steering column takes up a lot of space, and the layout is not flexible, so it is not convenient to arrange and install in the washing machine in a small space
[0006] 2. One set of mechanisms, it is difficult to completely take into account the switching of the three working modes of manual driving, automatic driving and remote driving
[0007] 3. The position control of the steering wheel mostly adopts open-loop control without steering wheel angle feedback
Before each power-on work, there is a lack of zero-point link, resulting in unstable control repeatability

Abstract

The invention discloses an automatic steering device for a floor cleaning machine, and a control method thereof. The automatic steering device comprises a manual driving control end, an automatic steering device driving end, and an automatic driving steering device control end. The automatic steering device completely realizes functions of steering control, corner feedback, and rapid and accurateresponse required in automatic driving of the floor cleaning machine, integrates three modes including manual driving, automatic driving and remote control driving, and can switch functions rapidly through buttons. The single device integrates three modes including manual driving, automatic driving and remote control driving of the floor cleaning machine. The manual driving control end is not directly, mechanically connected with the automatic steering device driving end, thereby being deployed on the floor cleaning machine conveniently and flexibly; a torque motor drives to produce steering resistance, so that the steering resistance is corresponding to manual operated steering wheel amplitude and is adjustable, and a user is clear about the path when operating to steer.

Description

technical field [0001] The invention relates to the technical field of automatic driving of a floor washing machine, in particular to an automatic steering device of a floor washing machine and a control method thereof. Background technique [0002] The automatic steering device of the washing machine is a steering device used on the washing machine. It uses gears, motors, encoders, reducers and controllers to realize the automatic steering function of the washing machine. After the washing machine is installed with the automatic steering device, it will have Automatic steering capability, and can also realize manual steering and remote steering functions. According to the needs of different application scenarios, the three functional modes of the automatic steering device, automatic steering, remote steering, and manual steering, can be quickly switched through the function buttons. The automatic steering device of the washing machine is the key link to realize the automat...
