Abstract: A method and system for controlling rollover calibration settings of a vehicle is disclosed. The vehicle has a roll axis extending from a front end of the vehicle to a back end of the vehicle. The method comprises monitoring an off-road signal indicating whether the vehicle is operating in an off-road mode or a default mode, monitoring a speed signal indicative of the speed of the vehicle, and selecting the rollover calibration settings of the vehicle based on the off-road signal and the speed signal.

Abstract: A motor vehicle impact sensing system for a vehicle that includes a controller that is connected to a pressure sensor that cooperates with a discrete deformable vessel. The pressure sensor is operatively positioned relative to the deformable vessel such that changes in the vessel generate a signal indicative of a pressure change. The signal associated with the pressure change is communicated from the pressure sensor to the controller. If the signal exceeds a threshold, such as where there is a rapid pressure increase in the vessel, the controller initiates one or more safety measures, such as deploying airbags or the like, to reduce the effects of an undesired impact. The deformable vessel and pressure sensor form a sensor assembly that can be located in one or more of various locations throughout the vehicle including its front end, its doors, quarter panels, side panels, and/or its rear end.

Abstract: A motor vehicle is provided that has a deployable occupant protection device, a controller that manages deployment activity, and a sensor located in a forward portion of the vehicle that produces a forward crash signal in response to crash stimulus. The forward crash signal varies between positive and negative values over time. At least some of the negative values are converted to positive values, defining a conditioned crash signal which is processed with an integrating algorithm, defining a conserved energy crash metric value that supplements processing of a central crash signal while evaluating a potential crash event(s). The conserved energy crash metric value can be used as a confirmatory factor, influencing whether to deploy the deployable occupant protection device. Or, for deployable occupant protection devices having multiple deployment stages, the conserved energy crash metric value can be used in determining whether to initiate one or more of the deployment stages.

Abstract: An impact sensing apparatus for a motor vehicle includes a control module having an accelerometer and a contact switch mounted in a bumper of the motor vehicle. The contact switch is in an open position and is in communication with the control module. The control module deploys an airbag when the accelerometer detects a change in velocity of the motor vehicle exceeding a threshold lowered when the contact switch is urged by the bumper to a closed position.
