Controlling system for self-propelled floor cleaning vehicles
First Claim
1. In an improved controlling system for a self-propelled floor cleaning vehicle equipped with a drive means for driving said vehicle, a floor cleaning means, a speed controller means that controls the speed of the drive means and a means for steering the vehicle along a preselected path defined by a guidance line on a floor surface to be cleaned, the improvement which comprises a sensing means associated with the vehicle for sensing a level of dirt or scratching on the floor surface over which the vehicle passes wherein the sensing means cooperates with the speed controller means to adjust the speed of the drive means relative to the level of dirt or scratching sensed on the floor surface over which the vehicle passes.

Abstract
This invention provides an improved method and system for controlling a self-propelled floor cleaning vehicle characterized by the fact that the vehicle has excellent cleaning performance. This method is applied to a floor cleaning vehicle that follows a guidance line located on the floor. It detects the level of dirt or scratching present on the floor and it controls the running speed of the floor cleaning vehicle corresponding to the amount of the dirt or scratching detected. It is thus able to modify the cleaning and polishing/buffing operation in response to the amount of dirt or scratching on the floor.
