Dual-mode drive-by-wire steering system

A dual-mode steering system for an automotive vehicle comprising:

• a first steering mechanism comprising;
• a first articulatable member;
• a second articulatable member;
• and
• a linkage assembly mechanically coupled to said first articulatable member and said second articulatable member;
• a second steering mechanism comprising;
• a center hub assembly;
• a first extending arm mechanically coupled to said first articulatable member and said central hub assembly;
• and
• a second extending arm mechanically coupled to said second articulatable member and said central hub assembly;
• a locking mechanism mechanically coupled to said linkage assembly;
• a locking switch having a first state and a second state;
• and
• a controller electrically coupled to said locking mechanism and said locking switch, said controller locking said first steering mechanism to said second steering mechanism when said locking switch is in said first state and disengaging said first steering mechanism from said second steering mechanism when said locking switch is in said second state.

A method of operating a dual-mode steering system for an automotive vehicle comprising:

• switching a locking switch to a first state or a second state;
• locking a first steering mechanism to a second steering mechanism to form a combined steering mechanism or unlocking said first steering mechanism from said second steering mechanism when said locking switch is in said first state or said second state, respectively;
• and
• rotating said combined steering mechanism or rotating said first steering mechanism when said locking switch is in a first state or a second state, respectively, to steer the vehicle.
