Abstract
A rollover prevention device and method detects an impending rollover situation for a vehicle (10) having a high center of gravity (cg). The system alerts the operator to potentially dangerous driving conditions and/or automatically slows the velocity of the vehicle (10) to prevent rollover. An electronic control unit for receives output signals from wheel velocity, engine revolution, and engine load sensors and then calculates lateral acceleration, wheel slip difference, and drive torque from the signals. A lateral acceleration limit is defined by plotting lateral acceleration, wheel slip difference and drive torque as a three dimensional surface.
