Control of vehicle rollover
First Claim
1. A motor vehicle characterized by a center of gravity, comprising:
- a vehicle body;
a plurality of wheels for maintaining contact with a road surface;
a roll-reduction apparatus configured to resist an impending rollover of the vehicle via at least one of i) applying a force between the vehicle body and at least one of the plurality of wheels and ii) lowering of the center of gravity of the vehicle;
a sensing device configured to detect a roll moment acting on the vehicle and having a threshold magnitude; and
a controller configured to trigger the roll-reduction apparatus to generate a moment on the vehicle body opposite to the detected roll moment having the threshold magnitude such that an angle of the vehicle with respect to the road surface during the rollover is reduced.

Abstract
A motor vehicle includes a body characterized by a center of gravity, a plurality of wheels for maintaining contact with a road surface, and a roll-reduction apparatus. The apparatus is configured to resist an impending rollover of the vehicle via at least one of i) applying a force between the body and at least one of the plurality of wheels and ii) lowering of the center of gravity of the vehicle. The vehicle also includes a sensing device configured to detect a roll moment acting on the vehicle and having a threshold magnitude. The vehicle additionally includes a controller configured to trigger the roll-reduction apparatus to generate a moment on the body opposite to the detected threshold moment such that an angle of the vehicle relative to the road surface during rollover is reduced. A method of reducing the angle of the body during rollover is also disclosed.
