Claim 5:
6. An anti-roll steering apparatus having:
a steering input device, a steering column, a steering actuation device, and a set of steerable guide wheels of a vehicle, wherein said steering input device is in mechanically operative communication with said set of steerable guide wheels of said vehicle such that said set of steerable guide wheels are mechanically slaved to said steering input device such that rotation of said steering input device causes a corresponding change in an angular position of said steerable guide wheels relative to the body of said vehicle,
at least one sensor adapted to sense the magnitude of at least one driving parameter,
at least one actuator operatively adapted to actuate upon receipt of an actuation signal, and
an electronic control unit adapted to send an actuation signal to said actuator when a sensed driving parameter exceeds a predetermined magnitude,
wherein said apparatus has a first mode such that for the duration of when said apparatus is in said first mode, always allows said vehicle to be steered within a maximal non-rollover steering range of motion of said vehicle but always prevents said vehicle from being steered to a point of roll of said vehicle at any rollover capable speed of said vehicle regardless of an oversteer load being applied to said steering input device and regardless of the source of said oversteer load and without locking said steering column such that all rotational movement of said steering column is prevented, and
wherein said apparatus has a second mode that allows said vehicle to be steered within a maximal non-rollover steering range of motion of said vehicle but does not prevent said vehicle from being steered to a point of roll of said vehicle, and
wherein said apparatus transitions from said first mode to said second mode in response to an application of a non-oversteer load to said steering input device, and
wherein if said guide wheels are turned beyond an angular position point of a rollover threshold of said vehicle, said vehicle will roll over.
