Method and system for automatic wheel positioning

1. A system for angularly positioning the wheels of an automotive vehicle having a power-assisted steering system, after parking the vehicle, the system comprising:

a controller coupled to the steering system, wherein the controller is configured to:

identify a parked state of the vehicle;

on identifying the parked state, the controller being further configured to receive a manual input from a driver, including:

in response to determining the manual input is received from a driver, directing the controller to position the wheels of the vehicle in a specific direction, then commanding the steering system to position the wheels in the specific direction;

in response to determining the manual input is not received from the driver, then upon identifying that the vehicle is parked on a slope and that a road curb exists in proximity to the wheels of the vehicle, then commanding the steering system to position the wheels toward the road curb;

wherein the wheels are positioned at a predetermined angular orientation, the angular orientation being based on one or more of the steepness of the slope, vehicle specifications, or ambient temperature.

2. The system of claim 1 , wherein the signal to the steering system angularly rotates the wheels in a right or a left direction.

3. The system of claim 1 , wherein the wheels are the front wheels of the vehicle.

4. The system of claim 1 , wherein the controller further includes a grade detector for identifying whether the vehicle is parked on a slope.

5. The system of claim 4 , wherein the controller is configured to transfer the signal to the steering system automatically based on a determination that the vehicle is parked on a slope.

6. The system of claim 1 , wherein the controller includes a curb detector configured to identify the position of road curb in close proximity of the wheels.

7. The system of claim 6 , wherein the controller is configured to transfer the signal for automatically angularly positioning the wheels towards the road curb.

8. The system of claim 1 , wherein the controller is configured to transfer the signal to the steering system through a manual input.

9. The system of claim 8 , wherein the manual input includes one or more of an angular direction in which the wheels should be rotated, and the extent of rotation for the wheels.

10. The system of claim 1 , wherein the controller is further configured to reposition the wheels based on a determination that the vehicle is no more in the parked state.

11. A method for automatically angularly positioning vehicle wheels after parking, the method comprising:

upon a determination by a controller that a vehicle ignition has been turned off, initiating the method by the controller;

in response to determining a manual input is received from a driver directing the controller to position the wheels in a specified angular commanding a power-assisted steering system to position the wheels in the specified direction;

in response to determining no manual input is received from the driver, then upon identifying that the vehicle is parked on a slope and that a road curb exists in proximity to the wheels of the vehicle, commanding the steering system to position the wheels towards the curb;

wherein, the wheels are positioned at a predetermined angular orientation, the angular orientation being based on one or more of the steepness of the slope, vehicle specifications, or ambient temperature.

12. The method of claim 11 , wherein the positioning step includes automatically positioning the wheels.

13. The method of claim 11 further includes repositioning the wheels upon a determination that the ignition is turned on.

14. The method of claim 11 , wherein the identifying step further includes determining the grade of the surface.

15. The method of claim 14 , wherein the transmitting step includes transmitting the signal based on a determination by a sensor that the vehicle is parked on a slope.
