Zusammenfassung:A materials handling vehicle comprises a wheel and a vehicle computing device, wherein: the vehicle computing device stores logic that when executed by a processor, causes the materials handling vehicle to perform at least the following: determine a current location of the materials handling vehicle within a warehouse; determine an odometry distance from the current location to a destination based on a calculation of a determined number of rotations of the wheel and a circumference of the wheel; determine a positioning system distance from the current location to the destination; compare the odometry distance with the positioning system distance to calculate a scaling factor; apply the scaling factor to a slow alpha filter to achieve a slow filter result; apply the scaling factor to a fast alpha filter to achieve a fast filter result; in response to determining that the slow filter result is within a predetermined tolerance of the fast filter result, apply the slow alpha filter to the scaling factor to smooth noise; calculate an updated odometry distance utilizing the scaling factor; and utilize the updated odometry distance to operate a positioning system.
