Motorized wheelchair and control method thereof

A method of controlling a motorized wheelchair having two rear wheels, the method comprising:

• determining an inclination angle of a surface on which the motorized wheel chair is travelling;
• when the inclination angle is less than a reference angle, performing a first turning operation associated with a rotational center located substantially at a midpoint between the two rear wheel;
• and
• when the inclination angle is greater than or equal to the reference angle, performing a second turning operation having a turning radius that is greater than a turning radius of the first turning operation.

A method of controlling a motorized wheelchair having left and right driving wheels, the method comprising:

• determining an inclination angle of a surface on which the motorized wheel chair is travelling;
• and
• controlling respective rotational speeds of the left and right driving wheels when the motorized wheel chair is performing a turning operation, wherein controlling the respective rotational speeds of the left and right driving wheels includes:
• controlling the respective rotational speeds of the left and right driving wheels to turn the motorized wheel chair with a first turning radius when the inclination angle is less than a reference angle;
• and
• controlling the respective rotational speeds of the left and right driving wheels to turn the motorized wheel chair with a second turning radius that is greater than the first turning radius when the inclination angle is greater than or equal to the reference angle.
