WEARABLE WIRELESS REMOTE CONTROL DEVICE FOR USE WITH A MATERIALS HANDLING VEHICLE

摘要

A supplemental remote control system for a materials handling vehicle includes a wireless remote control device that is useable by an operator interacting with the materials handling vehicle. Actuation of a travel control on the remote control device causes a wireless transmitter on the device to transmit a travel request to the vehicle. The remote control system further includes a receiver for receiving transmissions from the wireless transmitter at the vehicle and a controller at the vehicle in communication with the receiver for implementing the travel request. The wireless remote control device further includes an input component, wherein actuation of the input component causes the wireless transmitter to wirelessly transmit a second type of request to the receiver on the vehicle requesting the controller to implement a second vehicle function other than to advance the vehicle.

1. A supplemental remote control system for a materials handling vehicle comprising:
a wireless remote control device that is useable by an operator interacting with said materials handling vehicle, said wireless remote control device comprising:
a wireless transmitter; anda travel control communicably coupled to said wireless transmitter, wherein actuation of said travel control causes said wireless transmitter to wirelessly transmit a travel request as a first type signal requesting said vehicle to advance in a first direction; a receiver for receiving transmissions from said wireless transmitter at said vehicle; a controller that is communicably coupled to said receiver and to a traction control system of said vehicle, said controller being responsive to receipt of said first type signal by said receiver to evaluate at least one vehicle condition, to decide whether to implement said travel request based upon the evaluation of said at least one vehicle condition and to cause said traction control system to advance said vehicle if said controller decides to implement said travel request based upon the evaluation of said at least one vehicle condition; wherein said wireless remote control device further comprises an input component communicably coupled to said wireless transmitter, wherein actuation of said input component causes said wireless transmitter to wirelessly transmit a second type of request to said receiver on said vehicle requesting said vehicle to perform a second vehicle function other than to advance said vehicle.
