A method for rollover sensing () that may be used in the determination of when to deploy restraints in a vehicle is disclosed herein. The method for rollover sensing () may include lateral acceleration sensors (), a roll rate sensor (), and a roll angle detector (). A control circuit () determines a roll moment of inertia as a function of lateral acceleration, a trip point length as a function of the lateral acceleration, and a trip point angle as a function of the lateral acceleration. The control circuit () also determines a rollover threshold in response to a roll rate signal, a roll angle signal, the trip point length, the roll moment of inertia, and the trip point angle. The control circuit () further generates a control signal for a deployment circuit in response to the rollover threshold.

Method for detecting rollover of an automotive vehicle based on a lateral kinetic energy rate threshold

An automobile rollover detection system comprising a control module to receive a first set and a second set of signals, to determine a first threshold in response to the first set of signals, to determine a second threshold in response to the second set of signals, to provide a first signal in response to the first threshold, to provide a second signal in response to the second threshold, and to provide a control signal in response to the first and second signals. The control signal may activate an occupant restraint system in response to the detection of an automobile rollover event. Other embodiments are also claimed and described.

Method and apparatus for detecting rollover of an automotive vehicle based on a lateral kinetic energy rate threshold

Methods and systems for detecting automobile rollover

A restraint control system () for an automotive vehicle () is illustrated with a first sensor such as a door cavity pressure sensor () and a second sensor such as an accelerometer (). A restraint device () is coupled to a controller () that controls the operation of the restraint device in response to the first sensor () and the second sensor (). When either the signal from the first sensor or the signal from the second sensor is above a first or second threshold, respectively, the two signals are compared. In response to the comparison, the restraint device () is deployed.
