Abstract: A method and system for detecting a vehicle rollover or dangerous situations that may precede a rollover, in particular a soil trip type rollover includes the following steps, where the steps are performed in loops, (a) determining a lateral acceleration of the vehicle, (b) calculating an acceleration differential value on the basis of the lateral accelerations determined in at least two steps (a), (c) determining a possibility of a rollover of the vehicle on the basis of the lateral acceleration determined in at least one step (a) and the acceleration differential value calculated in at least one step (b), (d) generating an output activation signal at least on the basis of a possibility of a rollover of the vehicle determined in a step (c).

Abstract: A safety logic for vehicle rollover detection systems comprising a main rollover detection logic and at least one protection device for the occupant or occupants of the vehicle, including a vehicle lateral acceleration sensor (11), which generates an output signal indicating a near rollover event, when a lateral acceleration of a vehicle exceeds the first predefined threshold value (15) or, when a lateral acceleration of vehicle exceeds the second predefined threshold value (16) that is lower than the first predefined threshold value (15) and simultaneously at least one additional safety logic activation signal is present (1, 1?, 1?, 1??).

Abstract: The absolute roll angle of a vehicle body is estimated by blending two preliminary roll angle estimates based on their frequency so that the blended estimate continuously favors the more accurate of the preliminary roll angle estimates. A first preliminary roll angle estimate based on the measured roll rate is improved by initially compensating the measured roll rate for bias error using roll rate estimates inferred from other measured parameters. And a second preliminary roll angle estimate is determined according to the sum of the road bank angle and the relative roll angle. The blended estimate is used to estimate the actual lateral acceleration, the lateral velocity and side-slip angle of the vehicle, which are used in rollover detection and other various other control applications.

Abstract: The absolute roll angle of a vehicle body is estimated by blending two preliminary roll angle estimates based on their frequency so that the blended estimate continuously favors the more accurate of the preliminary roll angle estimates. A first preliminary roll angle estimate based on the measured roll rate is improved by initially compensating the roll rate signal for bias error using roll rate estimates inferred from other measured parameters. And a second preliminary roll angle estimate is determined based on the kinematic relationship among roll angle, lateral acceleration, yaw rate and vehicle speed. The blended estimate of roll angle utilizes a blending coefficient that varies with the frequency of the preliminary roll angle signals, and a blending factor used in the blending coefficient is set to different values depending whether the vehicle is in a steady-state or transient condition.
