Abstract
A control system for industrial use vehicles such as battery powered fork lifts in which regenerative energy is saved when the direction of travel is reversed. The control system functions to moderate the current drain on the battery. The control system comprising: a travel signal input means for generating an output signal from a travel accelerator, a cargo-handling signal input means for generating a cargo-handling signal, a monitor voltage input means for detecting a voltage at each of a plurality of monitor points and for outputting a detected signal, a sensor input means for generating an output signal from each sensor, monitor input means for generating an output signal from each monitor, and a microprocessor controller for receiving the output signals of the respective means and for outputting predetermined control signals.
