An anti-theft apparatus (10) for use on a vehicle includes a torque sensor (16) for sensing applied steering torque and providing a signal (24) indicative thereof. A power assist motor (22) steerably connected to steerable wheels (20) of the vehicle. A detector (62) detects whether the vehicle has an authorized user. A controller (26) controls the power assist motor (22) in response to the steering torque signal (24). The controller (26) controls the power assist motor (22) in a first mode responsive to the sensed applied steering torque signal (24) when the detector (62) detects that the vehicle has an authorized user and in a second mode responsive to the sensed applied steering torque signal (24) when the detector (62) detects that the vehicle does not have an authorized user. The detector (62) detects an authorized user by sensing vehicle ignition using an authorized key or authorized entry to the vehicle's interior. |
