Abstract

A method for predicting the future operation of a vehicle is disclosed which uses stored data representative of commonly followed routes to predict the future operation of the vehicle for the current trip. By establishing that the route currently being followed is comparable to one of the commonly followed routes, information relating to that “common route” is then used to predict the future operation of the vehicle for the current trip.

First claim

The invention claimed is:

1. A method of predicting a future operation of a vehicle wherein the method comprises automatically carrying out the steps of:
identifying a user of the vehicle;
monitoring one or more operating parameters of the vehicle for each trip conducted by the user;
storing data collected from the monitoring for the user;
establishing and storing common patterns of operation from the stored data for the user;
determining a current common pattern of operation based on the user of the vehicle, the one or more operating parameters, and the stored common patterns of operation;
using current common pattern of operation for predicting the future operation of the vehicle during a current trip; and
using the predicted future operation of the vehicle during the current trip to improve at least one of charging of a battery of the vehicle, a supply of a reductant to an exhaust aftertreatment device of the vehicle, and a control of an engine of the vehicle for the purpose of regenerating the exhaust aftertreatment device of the vehicle;
wherein the method of predicting the future operation of the vehicle is carried out via an electronic processing system.

2. The method of claim 1 , wherein the one or more operating parameters are monitored against one of time and distance travelled for a duration of the trip.

3. The method of claim 2 , wherein the one or more operating parameters are characteristic vehicle parameters comprising engine speed, vehicle speed, and engine torque.

4. The method of claim 2 , wherein the one or more operating parameters are characteristic user parameters selected from an accelerator pedal position, a rate of change of accelerator pedal position, a brake pedal position, a gear selector position, a steering wheel rotational position, a rate of change of steering wheel rotational position, and a clutch pedal position.

5. The method of claim 2 , wherein establishing common patterns of operation comprises comparing at least two of the operating parameters against the stored common patterns of operation for the same parameters to determine whether there is concurrence between the various patterns of operation and, if there is concurrence between several stored patterns of operation, storing characteristics of the pattern of operation as a common pattern of operation.

6. The method of claim 1 , wherein an identity of the user is established using at least one of a code stored in a key-fob, an indication of a position of a seat for the user of the vehicle, an indication of a radio station selected by the user of the vehicle, a position of an exterior mirror, and a weight of the user of the vehicle.

7. The method of claim 2 , wherein the determining further comprises comparing at least two of the operating parameters against the stored common patterns of operation for the same parameters and, if there is concurrence between the current pattern of operation and one of the stored common patterns of operation, using the respective common pattern of operation to predict the future operation of the vehicle for the current trip.

8. A vehicle having an electronic processing system to provide a prediction of a future operation of a vehicle for a current trip wherein the electronic processing system is operable to automatically:
identify a user of the vehicle;
monitor one or more operating conditions of the vehicle for each trip conducted by the user;
store data collected from the monitoring for the user in a memory;
establish and store common patterns of operation from the stored data for the user;
determine a current common pattern of operation based on a comparison between a current pattern of operation with the stored common patterns of operation for the user, where the determining is not based on a navigation system;
use the current common pattern of operation to predict the future operation of the vehicle during the current trip if the current pattern of operation conforms to a particular one of the stored common patterns of operation for the user; and
use the predicted future operation of the vehicle during the current trip to improve at least one of charging of a battery of the vehicle, a supply of a reductant to an exhaust aftertreatment device of the vehicle, and a control of an engine of the vehicle for the purpose of regenerating the exhaust aftertreatment device of the vehicle.

9. The vehicle of claim 8 , wherein the electronic processing system is operable to establish an identity of the user using at least one of a code stored in a key-fob, an indication of a position of a seat for the user of the vehicle, an indication of a radio station selected by the user, a position of an exterior mirror, and a weight of the user, and wherein the determining is further based on the identity of the user.

10. The method of claim 8 , wherein establishing common patterns of operation comprises comparing at least two of the operating parameters against the stored common patterns of operation for the same parameters to determine whether there is concurrence between the various patterns of operation and, if there is concurrence between several stored patterns of operation, storing characteristics of the pattern of operation as a common pattern of operation.

11. The method of claim 8 , wherein the comparison comprises comparing at least two of the operating parameters against the stored common patterns of operation for the same parameters and, if there is concurrence between the current pattern of operation and one of the stored common patterns of operation, using the respective common pattern of operation to predict the future operation of the vehicle for the current trip.

12. A method of predicting a future operation of a vehicle wherein the method comprises, via an electronic processing system, automatically carrying out the steps of:
identifying a user of the vehicle;
monitoring one or more operating parameters of the vehicle for each trip conducted by the user;
storing data collected from the monitoring for the user;
establishing and storing common patterns of operation from the stored data for the user;
determining a current common pattern of operation based on the user of the vehicle, the one or more operating parameters, and the stored common patterns of operation;
using current common pattern of operation for predicting the future operation of the vehicle during a current trip; and
using the predicted future operation of the vehicle during the current trip to improve of charging of a battery of the vehicle, a supply of a reductant to an exhaust aftertreatment device of the vehicle, and a control of an engine of the vehicle for the purpose of regenerating the exhaust aftertreatment device of the vehicle;
wherein the monitoring the one or more operating parameters of the vehicle for each trip conducted by the user comprises monitoring a number of characteristic parameters against one of time and distance travelled for a duration of the trip;
wherein the characteristic parameters are a combination of characteristic vehicle parameters and characteristic user parameters;
wherein the characteristic vehicle parameters comprise engine speed, vehicle speed, and engine torque.

13. The method of claim 12 , wherein the one or more operating parameters comprise engine speed, vehicle speed, and engine torque, and wherein the determining is not based on a navigation system.

14. The method of claim 12 , wherein the one or more operating parameters are selected from an accelerator pedal position, a rate of change of accelerator pedal position, a brake pedal position, a gear selector position, a steering wheel rotati
