1. A system for preventing rollover of a road vehicle having a plurality of road wheels, the system comprising:
- a vehicle suspension device located proximate to each of the vehicle'"'"'s road wheels for maintaining a predefined vehicle body height with respect to a road surface; and
a control unit in communication with the vehicle suspension device and having executable code for controlling the actuation of the vehicle suspension device to lower a body of the vehicle to counteract a roll moment after the control unit has received a vehicle rollover notification signal, the vehicle suspension device including an air bladder for raising or lowering the vehicle body, and a release valve in communication with the air bladder, the release valve being a diaphragm actuated release valve that is in communication with the air bladder.

6. A method for preventing a vehicle having a plurality of wheels from rolling over, the method comprising:
-
sensing a vehicle parameter; determining whether the vehicle is in a vehicle rollover condition based on the sensed vehicle parameter; determining a type of vehicle rollover condition based on the sensed vehicle parameter; actuating a vehicle suspension device to lower or raise a vehicle body based on the determined rollover condition to prevent the vehicle from rolling over; determining whether the vehicle is in a curve in a road; lowering a first side of the vehicle body by actuating the vehicle suspension device proximate to a wheel of the vehicle on a side of the vehicle where the vehicle body has been raised by vehicle roll; raising a second side of the vehicle body by actuating the vehicle suspension device proximate to the wheel of the vehicle on the side of the vehicle where the vehicle body has been lowered by vehicle roll; and injecting a fluid into the vehicle suspension device to raise the vehicle body. - View Dependent Claims (7, 8, 9, 10, 11, 12, 13, 14, 15, 16)
