Abstract
A method of triggering an active device of a vehicle at a pre-determined threshold comprises generating a steering wheel signal from steering angle rate of change of steering angle of the vehicle, the signal representing an advance in time in comparison to the steering wheel position and/or speed, and determining a conditioned vehicle lateral acceleration in dependence on the steering wheel signal and a measured vehicle lateral acceleration, the conditioned vehicle lateral acceleration being advanced in time in comparison with the measured vehicle lateral acceleration. An active device of the vehicle is triggered if the conditioned vehicle lateral acceleration exceeds a threshold lateral acceleration.
