Abstract

A method of vehicle and operator guidance by pattern recognition begins with collecting data on vehicle and operator patterns through sensors. The collected data is combined and analyzed with a pattern recognition algorithm. The combined and analyzed data is compared with patterns in a pattern database. If data matches a pattern in the pattern database, the pattern can be selected. If the data does not match a pattern in the pattern database, a new pattern can be created and selected. Based on the selected pattern, a determination is made to passively assist the operator, selectively assist the operator or passively and actively assist the operator. The determined action is then implemented.

Claims

1. A method of vehicle and operator guidance by pattern recognition, comprising:

providing a vehicle with a controller;

receiving data on vehicle and operator patterns through vehicle mounted sensors;

combining and analyzing said received data with a pattern recognition algorithm;

comparing said combined and analyzed data with patterns in a pattern database, wherein the controller either accepts the pattern if said combined and analyzed data matches a pattern in said pattern database or marks the combined and analyzed data as a new pattern not in said pattern database and accepts said new pattern into said pattern database;

determining, based on said pattern or new pattern, to passively assist an operator, actively assist the operator or passively and actively assist the operator; and

implementing the determined passive and/or active assistance,

wherein said passive and/or active assistance includes preparing for the movement of or moving said vehicle or components of said vehicle,

wherein said patterns in said pattern database comprise original patterns, updated patterns, received patterns and self-learned patterns, and

wherein self-learned patterns are created by said pattern recognition algorithm implemented by the controller by detecting vehicle or operator movements through said vehicle mounted sensors, grouping sensed data into patterns, recording said patterns in said pattern database, and comparing said recorded patterns to determine similarity, wherein comparing said recorded patterns includes comparing recorded patterns first to patterns in said pattern database used most frequently.

2. The method of claim 1, wherein said vehicle mounted sensors comprise vehicle sensors, sensors for driver actions and fleet management system sensors.

3. The method of claim 1, wherein similar patterns are grouped and saved in the pattern database and unsimilar patterns are removed from the pattern database.

4. The method of claim 1, wherein said original patterns are preloaded into said pattern database.

5. The method of claim 1, wherein said updated patterns take original patterns and update them based measurements from said vehicle mounted sensors learned during vehicle operation or operator operation.

6. The method of claim 1, wherein said received patterns are not original to the pattern database, but received from other vehicles or a fleet management system by said vehicle mounted sensors.

7. The method of claim 6, wherein said received patterns are created by one or more fleet vehicles performing a repetitive operation and are shared with other fleet vehicles.

8. The method of claim 1, wherein an operator overrides the implemented determined passive and/or active assistance.

9. The method of claim 1, wherein new patterns are entered into said pattern database when said operator records a set of executed repetitive actions and wherein new patterns are stored in a separate space in said pattern database.

10. The method of claim 1, wherein passive assistance anticipates the next driver actions based on pattern recognition.

11. The method of claim 1, wherein active assistance initiates the next driver action based on pattern recognition.

12. The method of claim 11, wherein initiation of the next driver action includes one of pre-filling a clutch or pre-engagement of a gear.

13. The method of claim 1, wherein said pattern includes repetitive movements made by at least one of said components of said vehicle.

14. The method of claim 1, wherein vehicle components include a fork, a mast or a bucket.

15. A method of vehicle and operator guidance by pattern recognition, comprising:

providing a vehicle with a controller;

receiving data on vehicle and operator patterns through vehicle mounted sensors;

combining and analyzing said received data with a pattern recognition algorithm;

comparing said combined and analyzed data with patterns in a pattern database, wherein the controller either accepts the pattern if said combined and analyzed data matches a pattern in said pattern database or marks the combined and analyzed data as a new pattern not in said pattern database and accepts said new pattern into said pattern database;

determining, based on said pattern or new pattern, to passively assist an operator, actively assist the operator or passively and actively assist the operator; and

implementing the determined passive and/or active assistance,

wherein said passive and/or active assistance includes preparing for the movement of or moving said vehicle or components of said vehicle, and

wherein implementing the determined passive and/or active assistance includes automatically taking control of components of said vehicle to perform passive and/or active assistance that completes said pattern or a portion thereof.

16. The method of claim 15, wherein passive and/or active assistance includes pre-engaging at least one of said components of said vehicle.

17. The method of claim 15, wherein components of said vehicle include a fork, a mast or a bucket.
