Abstract

Systems and method are provided for controlling a vehicle. In one embodiment, a method for selecting a driving mode for a vehicle includes receiving occupant preference information indicative of whether an occupant prefers that the vehicle operating in a driving mode (e.g., a sport mode), receiving a set of vehicle state parameters indicative of whether the operational state of the vehicle is conducive to the driving mode, and receiving a set of occupant state parameters indicative of the state of one or more occupants of the vehicle. The method further includes selecting a driving mode based on the occupant preference information, the set of vehicle state parameters, and the occupant state parameters, and then engaging vehicle tuning parameters for the vehicle based on the selected driving mode.

Claims

1. A computer implemented method of selecting a driving mode for a vehicle, the method comprising:

receiving, by a processor, a set of occupant state parameters indicative of a state of one or more occupants of the vehicle;

prompting, by the processor, the one or more occupants of the vehicle to select a first driving mode from a set of candidate sport modes that are specific to a number and a position of the one or more occupants of the vehicle and determined from the set of occupant state parameters;

receiving, by the processor, occupant preference information indicative of whether one or more occupants prefer that the vehicle operate in the first driving mode;

receiving, by the processor, a set of vehicle state parameters indicative of whether the state of the vehicle is conducive to the first driving mode;

selecting, by the processor, the first driving mode based on the occupant preference information, the set of vehicle state parameters, and the occupant state parameters; and

engaging, by the processor, vehicle tuning parameters for the vehicle based on the first driving mode.

2. The method of claim 1, wherein the vehicle tuning parameters include parameters relating to at least one of transmission shift points, maximum acceleration rate, torque converter clutch slip, exhaust noise, road noise engine mount rates, active noise cancellation, suspension softness, engine calibration, seat characteristics, cylinder deactivation, and maximum lateral acceleration.

3. The method of claim 1, wherein the set of occupant state parameters includes a determination as to whether one or more of the occupants are seated in a rear area of the vehicle.

4. The method of claim 3, wherein the set of occupant state parameters includes a determination as to whether one or more occupants are seated in a third row of the rear area of the vehicle.

5. The method of claim 1, wherein the set of occupant state parameters are determined in part from a set of optical sensors provided within an interior of the vehicle.

6. The method of claim 1, further including providing feedback to the occupant if the first driving mode is unavailable based on the occupant preference information, the set of vehicle state parameters, and the occupant state parameters.

7. An autonomous vehicle comprising:

one or more sensors provided within an interior of the autonomous vehicle, the one or more sensors configured to observe one or more occupants within the interior of the autonomous vehicle and produce sensor data associated therewith;

a driving mode determination module, including a processor, configured to, by the processor,

select a driving mode for the vehicle by;

receiving, by the processor, a set of occupant state parameters indicative of a state of one or more occupants of the vehicle;

prompting, by a processor, the one or more occupants of the vehicle to select a first driving mode from a set of candidate sport modes that are specific to a number and a position of the one or more occupants of the vehicle and determined from the set of occupant state parameters;

receiving occupant preference information indicative of whether the one or more occupants prefer that the vehicle operating in the first driving mode;

receiving a set of vehicle state parameters indicative of whether a state of the vehicle is conducive to the first driving mode; and

engaging vehicle tuning parameters corresponding to the first driving mode for the vehicle based on the occupant preference information, the set of vehicle state parameters, and the occupant state parameters.

8. The autonomous vehicle of claim 7, wherein the vehicle tuning parameters include parameters relating to at least one of transmission shift points, maximum acceleration rate, torque converter clutch slip, exhaust noise, road noise engine mount rates, active noise cancellation, suspension softness, engine calibration, seat characteristics, cylinder deactivation, and maximum lateral acceleration.

9. The autonomous vehicle of claim 7, wherein the set of occupant state parameters includes a determination as to whether one or more of the occupants are seated in a rear area of the vehicle.

10. The autonomous vehicle of claim 9, wherein the set of occupant state parameters includes a determination as to whether one or more occupants are seated in a third row of the rear area of the vehicle.

11. The autonomous vehicle of claim 7, wherein the set of occupant state parameters are determined in part from a set of optical sensors provided within an interior of the vehicle.

12. The autonomous vehicle of claim 7, further including providing feedback to the occupant if the first driving mode is unavailable based on the occupant preference information, the set of vehicle state parameters, and the occupant state parameters.

13. A system for selecting driving modes in an autonomous vehicle, the system comprising:

one or more sensors provided within an interior of the autonomous vehicle, the one or more sensors configured to observe one or more occupants within the interior of the autonomous vehicle and produce sensor data associated therewith;

a driving mode determination module, including a processor, configured to, by the processor, select a driving mode for the vehicle by;

receiving, by the processor, a set of occupant state parameters indicative of a state of one or more occupants of the vehicle;

prompting, by a processor, the one or more occupants of the vehicle to select a first driving mode from a set of candidate sport modes that are specific to a number and a position of the one or more occupants of the vehicle and determined from the set of occupant state parameters;

receiving occupant preference information indicative of whether the one or more occupants prefer that the vehicle operating in the first driving mode;

receiving a set of vehicle state parameters indicative of whether a state of the vehicle is conducive to the first driving mode;

engaging vehicle tuning parameters corresponding to the first driving mode for the vehicle based on the occupant preference information, the set of vehicle state parameters, and the occupant state parameters.

14. The system of claim 13, wherein the vehicle tuning parameters include parameters relating to at least one of transmission shift points, maximum acceleration rate, torque converter clutch slip, exhaust noise, road noise engine mount rates, active noise cancellation, suspension softness, engine calibration, seat characteristics, cylinder deactivation, and maximum lateral acceleration.

15. The system of claim 13, wherein the set of occupant state parameters includes a determination as to whether one or more of the occupants are seated in a rear area of the vehicle.
