Patent number: 9061603Abstract: An occupant detection system and method that uses an isolation assembly to isolate electrically a power supply providing power to a heater element for heating a vehicle seat from a sensing circuit that uses the heater element as an electrode for electric field or capacitance type occupant detection. The isolation assembly includes a common mode choke that by itself provides sufficient isolation when the sensing circuit excitation signal frequency is high enough, and provides switches that infrequently interrupt electrical power to the heater element so a humidity level can be determined using a relatively low excitation signal frequency. Knowing the humidity level is desirable to adjust a threshold use to determine if the sensing circuit indicates that the seat is empty, or is occupied.Type: GrantFiled: August 10, 2012Date of Patent: June 23, 2015Assignee: Delphi Technologies, Inc.Inventors: Thomas Fischer, Mike Albani

Patent number: 9063230Abstract: A sensor module configured to be located behind a window of a vehicle to detect an object through the window and about the vehicle. The module includes a radar unit with an antenna and a controller. The antenna emits and/or receives a radar signal through the window with a selected or preferred polarization. The polarization determines a preferred angle of propagation of the radar signal through the window based on reflection characteristics of the window that vary with impingement angle and transmitted polarization. By varying the transmitted polarization vs. beam direction when a directional antenna is used, the signal propagating through the windshield can be maximized to enhance object detection over a range of signal directions. Also, by varying the transmitted polarization when an omnidirectional type antenna is used, the object can be ‘illuminated’ with variable intensity and detected with variable sensitivity.Type: GrantFiled: November 6, 2013Date of Patent: June 23, 2015Assignee: Delphi Technologies, Inc.Inventors: Stephen W. Alland, Shawn Shi

Patent number: 9066085Abstract: A system, controller, and method for aligning a stereo camera of a vehicle mounted object detection system that includes a first camera and a second camera mounted spaced apart on a vehicle. An image from each camera at two different times is used to determine an observed displacement of an object relative to the vehicle. A predicted displacement of the object relative to the vehicle is also determined using either a difference of vehicle position measured based on other vehicle measurements or GPS, or a difference of size of the object in images taken at the two different times. Alignment is provided by determining a triangulation correction based on a difference of the observed displacement and the predicted displacement to correct for misalignment of the cameras.Type: GrantFiled: December 13, 2012Date of Patent: June 23, 2015Assignee: Delphi Technologies, Inc.Inventors: Charles A.
