Abstract

A system and method for providing driving support system to a vehicle. The vehicle includes a set of control modules, having at least one operational setting, configured for electronically controlling the vehicle components. The system includes an integrated drive mode selection module having a set of drive modes for modifying the settings for each control module. A sensing system detects at least one condition associated with the driver, vehicle or surroundings. A controller determines an appropriate drive mode for the vehicle based on the condition and the output of a safety module that ensures that the drive mode is safe while driving.

Claims

1. A driving support system for a vehicle, the system comprising:

a set of control modules configured for controlling the vehicle subsystems, each control module including at least one operational setting;

an integrated drive mode selection module having a set of drive modes for modifying the settings for each of the control modules;

a sensing system configured for identifying at least one condition associated with each of a driver, the vehicle, and surrounding objects or conditions;

a safety module configured for ensuring that a selected drive mode is safe while driving; and

a controller configured for determining an appropriate drive mode for the vehicle through an input, the controller determining the drive mode based on;

the condition; and

output of the safety module for the drive mode selected.

2. The system of claim 1, wherein the condition associated with the driver includes at least one of:

control capability;

intent;

behavior;

or

workload.

3. The system of claim 1, wherein the input includes:

driver'"'"'s selection;

an automatic mode which when activated automatically determines the drive mode for the vehicle;

or

a proactive mode which when activated determines the drive mode and recommends this drive mode for driver'"'"'s acceptance.

4. The system of claim 1, wherein the modes includes:

operational mode;

automatic mode; and

proactive mode.

5. The system of claim 1, wherein the safety module ensures that the selected drive mode is safe for the vehicle.

6. The system of claim 5, wherein the controller activates the selected drive mode based on the output of the safety module.

7. The system of claim 1, wherein the controller includes an arbitration module configured for:

computing a confidence score based on drive mode identified for each condition; and

determining an overall drive mode for the vehicle based on the confidence score associated with each condition; and

selecting a setting for each control module based on the overall drive mode.

8. The system of claim 7, wherein the arbitration module selects a separate setting for each of the control modules.

9. The system of claim 1, wherein the arbitration module selects a common setting for each of the control modules.
