Abstract: One general aspect includes a system to establish a deployment force for an airbag of a vehicle, the system includes: a memory configured to include one or more executable instructions and a processor configured to execute the executable instructions, where the executable instructions enable the processor to carry out the following steps: monitoring a head position of a vehicle occupant; based on the monitored head position, calculating a distance of a body part of a vehicle operator relative to a portion of an interior cabin of the vehicle; and based on the distance of the body part, establishing the deployment force for the airbag.

Abstract: A vehicle control system and a method for prolonging or extending the availability of certain safety-related features after an ignition unit has switched off or otherwise become inactive. The method can provide some safety-related features following an unintended ignition event, such as the type that can occur when the vehicle is involved in a multiple collision accident and the force of the initial impact unintentionally jars or switches the ignition unit off. In one example, the method uses a prolongation timer to temporarily power an airbag control module so that it is capable of sensing a crash and deploying an airbag for a period of time following the ignition being switched off.
