20080312788 | METHOD AND SYSTEM FOR IDENTIFYING OCCUPANTS OF VEHICLES - Signals indicative of the identity and location of vehicle occupants are broadcast and received. Received signals are inspected for identity information. Indications are made as to whether received identity information matches stored identity information. | 12-18-2008 |
20090093928 | Trailer Oscillation Detection and Compensation Method For A Vehicle And Trailer Combination - A system and method of controlling a vehicle with a trailer comprises determining the presence of a trailer, generating an oscillation signal indicative of trailer swaying relative to the vehicle, generating an initial weighted dynamic control signal for a vehicle dynamic control system in response to the oscillation signal, operating at least one vehicle dynamic system according to the dynamic control signal, and thereafter, iteratively generating a penalty function for the weighted dynamic control signal as a function of the oscillation signal response. A neural network with an associated trainer modifies the dynamic control signal as a function of trailer sway response. | 04-09-2009 |
20090207043 | WIRELESS, INFRASTRUCTURELESS COMMUNICATION SYSTEM FOR VEHICLES AND METHOD FOR THE SAME - The present invention is a wireless, infrastructureless, communication system for vehicle to vehicle data transfer over a 900 MHz frequency over a substantially 360° radius of view over a predetermined range, preferably about 8 miles. Each vehicle is equipped with a geo-position system, a warning alert system, at least one sensor to produce a data signal indicative of vehicle operation conditions, a micro-chip set and a transceiver. The invention further includes methods to communicate over a wireless, infrastructureless communication system for vehicle to vehicle data transfer over the described system. | 08-20-2009 |
20090296955 | VEHICLE AUDIO SYSTEM HAVING PORTABLE POWERED SPEAKER FOR CONNECTING A PORTABLE ENTERTAINMENT DEVICE - A vehicle audio system includes an interior trim panel having an opening with a speaker module removably secured therein and having a speaker electrically connected to the vehicle audio system when the speaker module is positioned within the opening. The speaker module includes an interface for receiving an audio signal from a linked portable electronic device for playing the audio signal through the speaker when the speaker module is removed from the interior trim panel opening and electrically disconnected from the vehicle audio system, and for playing the audio signal through the vehicle audio system when the speaker module is positioned within the interior trim panel. The speaker module may include an energy storage device and/or generator, such as a dynamo or solar cell, to power the speaker and play audio from a linked digital media player and/or recharge an electronic device, such as a media player or cell phone. | 12-03-2009 |
20100283593 | Wireless Seatbelt Monitoring System - A wireless seatbelt monitoring system and method is provided for informing a driver that a seatbelt that should be latched is unlatched. The system includes a wireless seatbelt assembly having a buckle equipped with a piezoelectric element and a transmitter. The transmitter sends a wireless seatbelt status signal when the seatbelt assembly is buckled by harvesting energy during the insertion process. The wireless seatbelt status signal is transmitted to a dedicated repeater module, which retransmits the wireless seatbelt status signal to a receiver. Based upon the wireless seatbelt status signal, the system informs the driver of the status of the seatbelt assemblies audibly, visually, or both. | 11-11-2010 |

20120081234 | Lane Departure Haptic Warning with Compensation for Road-Caused Vibration - A method of alerting the driver of a vehicle to a lane departure condition. The method includes operating a lane detection system to detect that the vehicle is experiencing a lane departure condition, operating a sensor to detect background vibration experienced by the vehicle, determining a characteristic making a haptic signal likely to be distinguishable from the background vibration, and operating a haptic signal generator in response to the lane departure condition to deliver to a driver the haptic signal having the characteristic. | 04-05-2012 |
20140039750 | Method And System For Implementing Ultrasonic Sensor signal strength calibrations - Temperature compensation for ultrasonic sensors can have a significant error that is highly undesirable because temperature of ultrasonic sensors and the temperature of the medium through which they sense objects affect signal strength calibrations (e.g., echo thresholds) applied when detecting an object. In order to increase the detection capabilities and reported distance of an object, ultrasonic sensors need to adjust their detection criteria and distance calculations as the temperature of air surrounding a vehicle (i.e., outside air temperature) changes and also as the temperature of the sensor changes. Embodiments of the inventive subject matter provide for a simple, effective and consistent approach for determining a temperature upon which such detection criteria and distance calculation adjustments can be based. | 02-06-2014 |
