Patent number: 8016319Abstract: A vehicle occupant classification system categorizes vehicle occupants into various classes such as adult, child, infant, etc. to provide variable control for a vehicle restraint system such as an airbag. The classification system utilizes sensors that are installed in various locations in the vehicle. The sensors are used to generate a three-dimensional profile for the vehicle occupant. Various factors can affect the accuracy of this three-dimensional profile. Fuzzy logic is used to reduce some of the inaccuracies by providing multiple decision levels for various stages of the classification. Inaccuracies are also caused by sensors shifting within the system from their original position. This condition creates offset and the system evaluates this offset and generates a correction factor to provide a more accurate three-dimensional profile.Type: GrantFiled: July 30, 2008Date of Patent: September 13, 2011Assignee: Siemens AGInventors: Gerd Winkler, Andreas Knueppel, Gerald Schicker

Patent number: 7324900Abstract: A distributed sensing system and method improves sensing of events that may require restraint deployment in a vehicle by distinguishing between deployment events and non-deployment events using data from more than one sensor. A transmission check process continuously monitors an incoming signal from a sensor and counts the number of data samples that exceed a selected value using a counter. If the counter value exceeds a selected threshold, the system indicates that the transmission check is fulfilled and allows deployment of the restraint. A correlation acceleration difference (CAD) algorithm calculates a CAD term corresponding to a degree of intrusion of a foreign object into a vehicle at a given time. Acceleration data from sensors disposed at supporting sides of the vehicle are checked if they respond to an event, and the absolute values of the acceleration data are subtracted from each other to obtain an absolute difference from which the CAD term is calculated.Type: GrantFiled: January 23, 2004Date of Patent: January 29, 2008Assignee: Siemens VDO Automotive CorporationInventors: Andreas Knueppel, Tobias Tyroller, Gerd Winkler

Patent number: 7203584Abstract: An air bag system (12) provides a central controller (14), a multiple of satellite sensors (16) and a multiple of deployable air bags (18). The central controller (14) runs the impact event algorithms. The number of satellites which are allowed to activate algorithms at any one time is limited. The minimum number of satellites required for full protection is the maximum number of satellite sensors allowed to wake up an impact event algorithm at any one time. An order for algorithm wake is also specified since the number of algorithms allowed is less than the total number of satellite sensors.Type: GrantFiled: May 4, 2005Date of Patent: April 10, 2007Assignee: Siemens VDO Automotive CorporationInventors: Robert M. Andres, Andreas Knueppel, Thomas J. Malbouef, Jr., Tobias Tyroller, Gerd Winkler

Publication number: 20050004729Abstract: A vehicle safety system (20) includes a controller (24) that verifies the plausibility of a roll angle indication obtained by processing a roll angular rate sensor (26) output. The controller (24) determines whether an acceleration value corresponding to the roll angle indication is within an expected range. In a disclosed example, the controller (24) utilizes a vertical acceleration value and a first expected range and a lateral acceleration value and a second expected range. When both of the acceleration values are outside of the respective expected range, the controller determines that the roll angle indication is invalid.Type: ApplicationFiled: June 25, 2004Publication date: January 6, 2005Applicant: Siemens VDO Automotive CorporationInventors: Jeffrey Gleacher, Ciprian Lucut, Robert Andres, Andreas Knueppel, Thomas Malbouef, Douglas McConnell, Eric Mertz, Scott Morell
