A materials handling vehicle includes an operator platform from which an operator can drive the vehicle; a traction control system for advancing the vehicle across a floor surface; at least one sensor configured to detect the presence of an object located at a position proximate to the vehicle; and
A materials handling vehicle includes an operator platform from which an operator can drive the vehicle; a traction control system for advancing the vehicle across a floor surface; at least one sensor configured to detect the presence of an object located at a position proximate to the vehicle; and a controller communicably coupled to the at least one sensor and the traction control system. The controller is responsive to the output of the at least one sensor to stop or slow down the vehicle if an object is detected proximate to the vehicle and the vehicle is traveling in response to a remote travel request. However, the controller does not slow down or stop the vehicle if an object is proximate to the vehicle while the operator is driving the vehicle on the operator platform.

1. A materials handling vehicle comprising: an operator platform from which an operator can drive the vehicle;a traction control system for advancing the vehicle across a floor surface;an operator presence sensor configured to detect the presence of the operator on the operator platform;at least one sensor configured to detect the presence of an object located at a position proximate to the vehicle; anda controller communicably coupled to the at least one sensor and the traction control system, wherein: the controller is responsive to the output of the at least one sensor to stop or slow down the vehicle if an object is detected proximate to the vehicle and the vehicle is traveling in response to a remote travel request; andthe controller does not slow down or stop the vehicle if an object is proximate to the vehicle while the operator is driving the vehicle on the operator platform; andwhen the controller receives a remote travel request, the controller evaluates the status of the operator presence sensor, and the controller is configured to: cause the traction control system to advance the vehicle if the status from the operator presence sensor is not indicative of the presence of an operator on the vehicle; anddecide to not implement the remote travel request if the status from the operator presence sensor is indicative of the presence of an operator on the vehicle. 2. The materials handling vehicle of claim 1, further comprising a load handling assembly, a power unit, and at least one steered wheel. 3. The materials handling vehicle of claim 1, further comprising an indicator that provides at least one of an audible and a visual cue when the vehicle is traveling in response to a remote travel request. 4. The materials handling vehicle of claim 1, wherein the object that is detected proximate to the vehicle comprises an object in the path of travel of the vehicle. 5. The materials handling vehicle of claim 4, wherein the controller is further communicably coupled to a brake control system for stopping the vehicle, and the controller is configured to cause the brake control system to stop the vehicle if the vehicle is moving under wireless remote control in response to receipt of a remote travel request and one or more of the at least one sensor indicates the detection of an object in the path of travel of the vehicle. 6. The materials handling vehicle of claim 1, wherein the output of the at least one sensor is overridden while the operator is driving the vehicle from the operator platform. 7. The materials handling vehicle of claim 1, wherein the controller is configured to decide to not implement the remote travel request if the status from one or more of the at least one sensor is indicative of the presence of an object proximate to the vehicle. 8. The materials handling vehicle of claim 1, wherein the remote travel request is requested by an operator of the vehicle using a wireless remote control device. 9. The materials handling vehicle of claim 8, wherein the remote control device is donned on at least one of the operator's finger, hand, arm, or wrist. 10. A method of operating a materials handling vehicle having a controller and an operator platform from which an operator can drive the vehicle, the method comprising: receiving, by the controller, an output of at least one sensor that is configured to detect the presence of an object located at a position proximate to the vehicle;receiving, by the controller, an output of an operator presence sensor;stopping or slowing down the vehicle, by the controller, if an object is detected proximate to the vehicle and the vehicle is traveling in response to a remote travel request;overriding, by the controller, the output of the at least one sensor if an operator is sensed on the vehicle by the operator presence sensor; andwhen the controller receives a remote travel request, the controller evaluates the status of the operator presence sensor, and the controller is configured to: cause the traction control system to advance the vehicle if the status from the operator presence sensor is not indicative of the presence of an operator on the vehicle; anddecide to not implement the remote travel request if the status from the operator presence sensor is indicative of the presence of an operator on the vehicle. 11. The method of claim 10, wherein the object that is detected proximate to the vehicle comprises an object in the path of travel of the vehicle. 12. The method of claim 10, wherein the controller is configured to decide to not implement the remote travel request if the status from one or more of the at least one sensor is indicative of the presence of an object proximate to the vehicle. 13. The method of claim 10, wherein the remote travel request is requested by an operator of the vehicle using a wireless remote control device, the remote control device being donned on at least one of the operator's finger, hand, arm, or wrist. 14. A materials handling vehicle comprising: an operator platform from which an operator can drive the vehicle;a traction control system for advancing the vehicle across a floor surface;an operator presence sensor configured to detect the presence of the operator on the operator platform;at least one sensor configured to detect the presence of an object located at a position proximate to the vehicle; anda controller communicably coupled to the at least one sensor and the traction control system, wherein: the controller is responsive to the output of the at least one sensor to stop or slow down the vehicle if an object is detected proximate to the vehicle and the vehicle is traveling in response to a remote travel request; andwherein the output of the at least one sensor is overridden while the operator is sensed on the vehicle by the operator presence sensor; andwhen the controller receives a remote travel request, the controller evaluates the status of the operator presence sensor, and the controller is configured to: cause the traction control system to advance the vehicle if the status from the operator presence sensor is not indicative of the presence of an operator on the vehicle; anddecide to not implement the remote travel request if the status from the operator presence sensor is indicative of the presence of an operator on the vehicle. 15. The materials handling vehicle of claim 14, wherein the controller is further communicably coupled to a brake control system for stopping the vehicle, and the controller is configured to cause the brake control system to stop the vehicle if the vehicle is moving under wireless remote control in response to receipt of a remote travel request and one or more of the at least one sensor indicates the detection of an object in the path of travel of the vehicle. 16. The materials handling vehicle of claim 14, wherein: the controller is configured to decide to not implement the remote travel request if the status from one or more of the at least one sensor is indicative of the presence of an object proximate to the vehicle. 17. The materials handling vehicle of claim 14, further comprising a load handling assembly, a power unit, and at least one steered wheel. 18. The materials handling vehicle of claim 14, further comprising an indicator that provides at least one of an audible and a visual cue when the vehicle is traveling in response to a remote travel request. 19. The materials handling vehicle of claim 14, wherein the object that is detected proximate to the vehicle comprises an object in the path of travel of the vehicle. 20. The materials handling vehicle of claim 14, wherein the remote travel request is requested by an operator of the vehicle using a wireless remote control device.
