Multiple Zone Sensing For Materials Handling Vehicles

Abstract A materials handling vehicle comprising: a power unit for driving the vehicle; at least one contactless obstacle sensor on the vehicle operable to define at least two detection zones; a controller that is configured to control at least one aspect of the vehicle, the controller further 5 configured to receive information obtained from the at least one obstacle sensor to: perform a first action if the vehicle is traveling under remote control in response to a travel request and an obstacle is detected in a first detection zone; and perform a second action different from the first action if the vehicle is traveling under remote control in response to a travel request and an obstacle is detected in a second detection zone; and a presence sensor for detecting whether 10 an operator is positioned on the vehicle, wherein the vehicle controller is configured to implement a travel request from a corresponding remote control device only when no operator is determined to be on the vehicle. 9022719_1(GHMatters) P87103.AU.2 ZO)NE-2 a a:
