Abstract

A process for implementing a materials handling vehicle feature monitor includes receiving wirelessly, from a fleet of materials handling vehicles, electronic vehicle records. Each electronic vehicle record comprises travel-related data recorded by an associated materials handling vehicle and an operator identification of the corresponding operator of the vehicle. The vehicle records are parsed for each operator to extract dashboard data, which can include a travel distance that the materials handling vehicle has traveled. An expected travel distance under remote control to total travel distance for the predetermined period of time is established. For each operator, an electronic measurement of the expected travel distance under remote control to total travel distance for the predetermined period of time compared to the recorded travel distance under remote control to total travel distance for the predetermined period of time is generated. A graphical representation of the generated measurements is outputted to a dashboard.

First claim

What is claimed is:

1. A process for implementing a monitor for materials handling vehicles having a remote control feature, comprising:
receiving wirelessly, from a materials handling vehicle being operated in a work environment by a corresponding operator, electronic vehicle records, each electronic vehicle record comprising:
travel-related data recorded by a controller on the materials handling vehicle; and
an operator identification of the corresponding operator of the materials handling vehicle;

parsing the vehicle records over a predetermined time period to extract dashboard data including:
a first travel distance that the materials handling vehicle traveled over the predetermined time period, responsive to the corresponding operator using a remote-controlled travel function; and
a total travel distance that the materials handling vehicle traveled over the predetermined time period;

establishing an expected travel distance under remote control to total travel distance for the predetermined period of time;
generating an electronic measurement of the expected travel distance under remote control to total travel distance for the predetermined period of time compared to the recorded travel distance under remote control to total travel distance for the predetermined period of time;
outputting to a dashboard, a graphical representation of the generated measurements;
analyzing, for the corresponding operator, the electronic measurement of the expected travel distance under remote control to total travel distance for the predetermined period of time compared to the recorded travel distance under remote control to total travel distance for the predetermined period of time;
selecting a materials handling vehicle control modification based upon the analysis; and
wirelessly transmitting the materials handling vehicle control modification to the materials handling vehicle, wherein the materials handling vehicle automatically implements the materials handling vehicle control modification to affect operation thereof.

2. The process of claim 1 , wherein:
receiving wirelessly, from the materials handling vehicle, electronic vehicle records, comprises receiving electronic vehicle records indicating whether:
travel occurred while a remote-control device was paired to a remote-control receiver; and
the travel occurred as a result of operation of the remote-control device paired to the remote-control receiver of the materials handling vehicle to implement the remote-controlled travel function; and

outputting to the dashboard, the graphical representation of the generated measurements further comprises outputting a graphical representation of:
an operator that is paired but does not operate the control feature of the remote-control device;
an operator that uses the control feature too infrequently compared to a target usage;
an operator that uses the control feature too frequently compared to the target usage parameter; or
an amount of time that a remote-control device is paired to a remote-control receiver of the corresponding materials handling vehicle.

3. The process of claim 1 further comprising:
outputting an indication of a technical issue with a remote-control device paired to a remote-control receiver of the materials handling vehicle to implement the remote-controlled travel function, the indication of the technical issue comprising a pairing failure; and
communicating a command back to a materials handling vehicle that reports a technical issue, to modify the performance of the materials handling vehicle to remedy the technical issue.

4. The process of claim 1 further comprising:
outputting an indication of a technical issue with a remote-control device paired to a remote-control receiver of the materials handling vehicle to implement the remote-controlled travel function, the indication of the technical issue comprising operating the materials handling vehicle without a paired remote; and
communicating a command back to a materials handling vehicle that reports a technical issue, to modify the performance of the materials handling vehicle to remedy the technical issue.

5. The process of claim 1 further comprising:
outputting an indication of a technical issue with a remote-control device paired to a remote-control receiver of the materials handling vehicle to implement the remote-controlled travel function, the indication of the technical issue comprising a number of remote-controls reporting a low battery; and
communicating a command back to a materials handling vehicle that reports a technical issue, to modify the performance of the materials handling vehicle to remedy the technical issue.

6. The process of claim 1 , wherein:
establishing an expected travel distance under remote control to total travel distance comprises establishing the expected travel distance under remote control to total travel distance as a range of ratios of travel distance under remote control to total travel distance; and
outputting to the dashboard, the graphical representation of the generated measurements comprises outputting a remote-control usage trend graph that trends a comparison of operator utilization of a control feature on a remote-control device paired to a remote-control receiver of the corresponding materials handling vehicle to implement the remote-controlled travel function, to the range, over time.

7. The process of claim 1 further comprising:
receiving a remote travel command; and
denying the remote travel command if the expected travel distance is greater than a first distance.

8. The process of claim 1 further comprising:
receiving a remote travel command; and
denying the remote travel command if the expected travel distance is less than a second distance.

9. The process of claim 1 further comprising:
receiving a remote travel command; and
allowing the remote travel command if the expected travel distance is less than a first distance and greater than a second distance.

10. The process of claim 1 further comprising:
determining that the electronic measurement of the expected travel distance under remote control to total travel distance for the predetermined period of time compared to the recorded travel distance under remote control to total travel distance for the predetermined period of time indicates an underutilization of the remote-control travel function;
determining a root cause of the underutilization is due to poor transmitter health of a remote control used to transmit the remote-controlled travel function; and
indicating that the underutilization is due to poor transmitter health.

11. The process of claim 10 , wherein:
determining a root cause of the underutilization is due to poor transmitter health includes determining that the remote control has a weak battery.

12. The process of claim 10 , wherein:
determining a root cause of the underutilization is due to poor transmitter health includes determining that the remote control has a broken antenna.

13. The process of claim 10 , wherein:
determining a root cause of the underutilization is due to poor transmitter health includes determining that the remote control has poor pairing stability with the vehicle.
