Abstract:
1. A method for controlling a vehicle to prevent rollover, comprising the steps of: measuring lateral acceleration of a vehicle; measuring one of a vehicle roll rate and vehicle suspension displacements; deriving an estimated roll angle from the measured lateral acceleration and the measured one of the vehicle roll rate and the vehicle suspension displacements; deriving a roll angle index from comparison of at least the measured lateral acceleration, the measured one of the vehicle roll rate and the vehicle suspension displacements and the estimated roll angle, wherein a magnitude of the roll angle index provides an indication of a rollover danger and a sign of the roll angle index provides a direction of impending rollover; and controlling at least one of vehicle braking and vehicle steering to reduce the possibility of rollover responsive to the roll control angle index.
