Abstract

Claims (71)

1 . A method, performed by a control arrangement, for controlling a powertrain of a vehicle, the method comprising:

in response to one or more driver-initiated indicators, adjusting a currently predicted route for the vehicle to a new predicted route, said new predicted route being predicted in consideration of information related to the one or more driver-initiated indicators;

determining a driving strategy for an upcoming road section of the new predicted route based on characteristics of said upcoming road section; and

controlling the powertrain in accordance with the determined driving strategy for the upcoming road section.

2 . The method according to claim 1 , further comprising:

determining the one or more driver-initiated indicators based on:

(i) a detection of activation of turn signals of the vehicle;

(ii) a detection of a steering wheel angle of the vehicle deviating from an expected steering wheel angle range of the vehicle;

(iii) a detection of a lateral velocity of the vehicle deviating from an expected lateral velocity of the vehicle; and/or

(iv) a detection of the vehicle approaching a geographical position where an alternative route, other than the currently predicted route, may be selected and the driver braking the vehicle in a manner judged to be consistent with the driver intending to select said alternative route.

3 . The method according to claim 1 , wherein the driving strategy comprises a gear selection strategy for a transmission arrangement of the powertrain.

4 . The method according to claim 1 , wherein the driving strategy comprises a targeted vehicle speed profile for the upcoming road section.

5 . The method according to claim 1 , further comprising:

identifying one or more possible route options for the vehicle within a predetermined distance in front of the vehicle; and

predicting which one of the one or more identified possible route options is the most likely upcoming route selection for the vehicle; and

selecting said route option as the currently predicted route for the vehicle.

6 . The method according to claim 5 , wherein predicting which one of the identified possible route options is the most likely upcoming route selection is made based on:

(i) data regarding historical route selections made by the vehicle and/or other road users;

(ii) data regarding road characteristics of the identified possible route options; and/or

(iii) data from a navigation system of the vehicle.

7 . A computer program product stored on a non-transitory computer-readable medium, said computer program product for controlling a powertrain of a vehicle, wherein said computer program product comprising computer instructions to cause one or more computing devices to:

in response to one or more driver-initiated indicators, adjust a currently predicted route for the vehicle to a new predicted route, said new predicted route being predicted in consideration of information related to the one or more driver-initiated indicators;

determine a driving strategy for an upcoming road section of the new predicted route based on characteristics of said upcoming road section; and

control the powertrain in accordance with the determined driving strategy for the upcoming road section.

8 . The computer program product according to claim 7 , wherein said computer program product comprising computer instructions to cause one or more computing devices to:

determine the one or more driver-initiated indicators based on:

(i) a detection of activation of turn signals of the vehicle;

(ii) a detection of a steering wheel angle of the vehicle deviating from an expected steering wheel angle range of the vehicle;

(iii) a detection of a lateral velocity of the vehicle deviating from an expected lateral velocity of the vehicle; and/or

(iv) a detection of the vehicle approaching a geographical position where an alternative route, other than the currently predicted route, may be selected and the driver braking the vehicle in a manner judged to be consistent with the driver intending to select said alternative route.

9 . The computer program product according to claim 7 , wherein said computer program product comprising computer instructions to cause one or more computing devices to:

identify one or more possible route options for the vehicle within a predetermined distance in front of the vehicle;

predict which one of the one or more identified possible route options is the most likely upcoming route selection for the vehicle; and

select said route option as the currently predicted route for the vehicle.

10 . The computer program product according to claim 9 , wherein said selection of said route option as the currently predicted route for the vehicle is made based on:

(i) data regarding historical route selections made by the vehicle and/or other road users;

(ii) data regarding road characteristics of the identified possible route options; and/or

(iii) data from a navigation system of the vehicle.

11 . A control arrangement configured to control a powertrain of a vehicle, the control arrangement being configured to:

in response to one or more driver-initiated indicators, adjust a currently predicted route for the vehicle to a new predicted route, said new predicted route being predicted in consideration of information related to the one or more driver-initiated indicators;

determine a driving strategy for an upcoming road section of the new predicted route based on characteristics of said upcoming road section; and

control the powertrain in accordance with the determined driving strategy for the upcoming road section.

12 . The control arrangement according to claim 11 , further configured to:

determine the one or more driver-initiated indicators based on:

(i) a detection of activation of turn signals of the vehicle;

(ii) a detection of a steering wheel angle of the vehicle deviating from an expected steering wheel angle range of the vehicle;

(iii) a detection of a lateral velocity of the vehicle deviating from an expected lateral velocity of the vehicle; and/or

(iv) a detection of the vehicle approaching a geographical position where an alternative route, other than the currently predicted route, may be selected and the driver braking the vehicle in a manner judged to be consistent with the driver intending to select said alternative route.

13 . The control arrangement according to claim 11 , further configured to:

identify one or more possible route options for the vehicle within a predetermined distance in front of the vehicle; and

predict which one of the one or more identified possible route options is the most likely upcoming route selection and selecting said route option as the currently predicted route for the vehicle.

14 . The control arrangement according to claim 11 , further configured to:

identify one or more possible route options for the vehicle within a predetermined distance in front of the vehicle;

predict which one of the one or more identified possible route options is the most likely upcoming route selection for the vehicle; and

select said route option as the currently predicted route for the vehicle.

15 . The control arrangement according to claim 14 , wherein said selection of said route option as the currently predicted route for the vehicle is made based on:

(i) data regarding historical route selections made by the vehicle and/or other road users;

(ii) data regarding road characteristics of the identified possible route options; and/or

(iii) data from a navigation system of the vehicle.

16 . A management system configured to control a transmission arrangement of a vehicle powertrain, said management system comprising a control arrangement configured to:
