Method and system for independently electronically controlling steering of vehicle wheels

A system for independently controlling the steering of at least two wheels of a vehicle having a steering wheel for enabling a driver to turn the vehicle, the system comprising:

• a steering angle sensor for sensing a desired amount of turning of the vehicle;
• an electronic control unit coupled to the steering angle sensor;
• a first turning mechanism coupled to one of the wheels and the electronic control unit for turning the one of the wheels;
• a second turning mechanism coupled to the other one of the wheels and the electronic control unit for turning the other one of the wheels;
• wherein the electronic control unit is operative to determine a direction for the desired amount of turning, determine a first desired turning angle for one of the wheels and a second desired turning angle for the other one of the wheels based on the desired amount of turning of the vehicle and the direction of the turning of the vehicle, the second desired turning angle being one of the same as and different from the first desired turning angle, and control the first and second turning mechanisms based on the first and second desired turning angles, respectively, in order to independently control the turning of each of the wheels;
• a first and second valve stem attached to each of the wheels and each leaving a one-way check valve disposed therein for allowing air to flow into the wheels;
• a first and second pressure sensor disposed in each of the wheels for sensing a pressure in each of the wheels;
• and
• wherein the electronic control unit is further operative to control the first and second valve stems based on a comparison of the pressure sensed in each of the wheels in order to control the flow of air into each of the wheels.
