Abstract

The present invention features a material handling vehicle identification system. The material handling vehicle has a universal system processor for controlling the vehicle speed, acceleration, direction and motion of a plurality of different vehicles. A semiconductor memory device is permanently affixed to the chassis of the vehicle during the manufacturing process. This memory device contains a unique identification tag. The identification tag is remotely disposed from, but operatively connected to the system processor. The identification tag includes data for uniquely identifying the material handling vehicle. The system processor can control the performance of the vehicle as a function of the data in the identification tag, whereby the system processor becomes customized to operate consistant only with the vehicle in which it is installed.
