Abstract:
A drive-by wire steering system, comprising:a steering shaft being configured for a first angular displacement about a first axis greater than 180Â°, said steering shaft comprising a first geared portion and a first end, said first end being connectable to a vehicle's steering wheel; and a steering wheel return mechanism comprising a torsion member and a second geared portion, said first geared portion and said second geared portion being operatively engaged such that said first angular displacement of said steering shaft imparts a second angular displacement about a second axis to said steering wheel return mechanism, said torsion member being configured to generate a returning torque on said steering wheel return mechanism in response to said second angular displacement of said steering wheel return mechanism, said returning torque having a direction opposite said second angular displacement and being proportional to said second angular displacement.
