Abstract

Methods, systems, and apparatus for automatically determining and implementing a driving mode from a plurality of driving modes of a vehicle. The system includes a GPS unit configured to detect a geographical location of the vehicle. The system includes a memory configured to store a driving mode map identifying an initial driving mode based on a given geographical location. The system includes an input unit configured to receive a driving mode sensitivity indicating a desired level of driving aggressiveness. The system includes an electronic control unit (ECU). The ECU is configured to determine the driving mode based on the driving mode map, the detected geographical location of the vehicle, and the driving mode sensitivity. The ECU is configured to automatically adjust operation of the vehicle based on the adjusted driving mode by adjusting a suspension, throttle sensitivity, shift points, air conditioning usage, traction control, or stability control.

First claim

What is claimed is:

1. A system for automatically determining and implementing a driving mode from a plurality of driving modes of a vehicle, the system comprising:
an input unit configured to receive, from a user, a driving mode sensitivity indicating a desired level of driving aggressiveness, the driving mode sensitivity being one of more aggressive, neutral, or less aggressive; and
an electronic control unit (ECU) configured to:
determine an initial driving mode based on a detected geographical location of the vehicle,
determine an adjusted driving mode by adjusting the initial driving mode based on the driving mode sensitivity, the adjusted driving mode being a more aggressive driving mode than the initial driving mode when the driving mode sensitivity is more aggressive, the adjusted driving mode being the same as the initial driving mode when the driving mode sensitivity is neutral, or the adjusted driving mode being a less aggressive driving mode when the driving mode sensitivity is less aggressive, and
automatically adjust operation of the vehicle based on the adjusted driving mode by adjusting at least one of a suspension, a throttle sensitivity, shift points, an air conditioning usage, a traction control, or a stability control.

2. The system of claim 1 , further comprising a memory configured to store driving condition data associated with the detected geographical location of the vehicle, including topographical data, speed limit data, and road type data and store a driving mode map used by the ECU to determine the initial driving mode based on the driving condition data associated with the detected geographical location of the vehicle.

3. The system of claim 2 , further comprising a transceiver configured to receive traffic data, and
wherein the ECU is further configured to determine the initial driving mode based on the detected geographical location of the vehicle and the traffic data.

4. The system of claim 1 , further comprising a memory configured to store a user driving history indicating the user's driving habits at particular geographic locations or types of locations, and
wherein the ECU is further configured to determine the initial driving mode based on the detected geographical location of the vehicle and the user driving history.

5. The system of claim 1 , further comprising a transceiver configured to receive aggregate driving data indicating driving habits at particular geographic locations or types of locations for a plurality of users, and
wherein the ECU is further configured to determine the line the initial driving mode based on the detected geographical location of the vehicle and the aggregate driving data.

6. The system of claim 1 , further comprising a memory configured to store a driving mode map identifying the initial driving mode based on the detected geographical location,
wherein the input unit is further configured to receive an ad hoc driving mode change to an updated driving mode, and
wherein the memory is further configured to update the driving mode map based on the detected geographical location of the vehicle and the updated driving mode.

7. A vehicle automatically determining and implementing a driving mode from a plurality of driving modes, the vehicle comprising:
a memory configured to store a driving mode map identifying an initial driving mode based on a given geographical location;
an input unit configured to receive, from a user, a driving mode sensitivity indicating a desired level of driving aggressiveness, the driving mode sensitivity being one of more aggressive, neutral, or less aggressive; and
an electronic control unit (ECU) configured to:
determine the initial driving mode based on the driving mode map and a current geographical location,
determine an adjusted driving mode by adjusting the initial driving mode based on the driving mode sensitivity, the adjusted driving mode being a more aggressive driving mode than the initial driving mode when the driving mode sensitivity is more aggressive, the adjusted driving mode being the same as the initial driving mode when the driving mode sensitivity is neutral, or the adjusted driving mode being a less aggressive driving mode when the driving mode sensitivity is less aggressive; and
automatically adjust operation of the vehicle based on the adjusted driving mode by adjusting at least one of a suspension, a throttle sensitivity, shift points, an air conditioning usage, a traction control, or a stability control.

8. The vehicle of claim 7 , wherein the memory is further configured to store driving condition data associated with the current geographical location, including topographical data, speed limit data, and road type data, and
wherein the driving mode map identifies the initial driving mode based on the driving condition data associated with the current geographical location.

9. The vehicle of claim 7 , further comprising a transceiver configured to receive traffic data, and
wherein the ECU is further configured to determine the initial driving mode based on the driving mode map, the current geographical location, and the traffic data.

10. The vehicle of claim 7 , wherein the memory is further configured to store a user driving history indicating the user's driving habits at particular geographic locations or types of locations, and
wherein the ECU is further configured to determine the initial driving mode based on the driving mode map, the current geographical location, and the user driving history.

11. The vehicle of claim 7 , further comprising a transceiver configured to receive aggregate driving data indicating driving habits at particular geographic locations or types of locations for a plurality of users, and
wherein the ECU is further configured to determine the initial driving mode based on the driving mode map, the current geographical location, and the aggregate driving data.

12. The vehicle of claim 7 , wherein the input unit is further configured to receive an ad hoc driving mode change to an updated driving mode, and
wherein the memory is further configured to update the driving mode map based on the location data of the vehicle and the updated driving mode.

13. A method for automatically determining and implementing a driving mode from a plurality of driving modes of a vehicle, the method comprising:
storing, by a memory, a driving mode map identifying an initial driving mode based on a given geographical location;
determining, by an electronic control unit (ECU), the initial driving mode based on the driving mode map and a detected geographical location of the vehicle;
determining, by the ECU, an adjusted driving mode by adjusting the initial driving mode based on a driving mode sensitivity, the driving mode sensitivity being one of more aggressive, neutral, or less aggressive, and the adjusted driving mode being a more aggressive driving mode than the initial driving mode when the driving mode sensitivity is more aggressive, the adjusted driving mode being the same as the initial driving mode when the driving mode sensitivity is neutral, or the adjusted driving mode being a less aggressive driving mode when the driving mode sensitivity is less aggressive; and
automatically adjusting, by the ECU, operation of the vehicle based on the adjusted driving mode by adjusting at least one of a suspension, a throttle sensitivity, shift points, an air conditioning usage, a traction control, or a stability control.

14. The method of claim 13 , further comprising storing, by the memory, driving condition data associated with the geographical location of the vehicle, including topographical
