Patent number: 7734391Abstract: A communication for a vehicle (10) has a first transmitter (34) for transmitting a first signal relating to a first vehicle system (22) and a second transmitter (42) for transmitting a second signal relating to a second vehicle system (38). (FIG. 1) A single receiver (46) has a first reception mode (50) and a second reception mode (54). The first reception mode (50) is receptive to the first signal while the second reception mode (54) is receptive to the second signal. A control unit (58) switches the receiver (46) between the first reception mode (50) and the second reception mode (54).Type: GrantFiled: May 19, 2004Date of Patent: June 8, 2010Assignee: Continental Automotive Systems US, Inc.Inventors: Jean-Christophe Deniau, Brian Farrell, Sanjaya Kumar Dash, Tejas B. Desai

Patent number: 7127369Abstract: A system with a sensor assembly is used to determine direction of movement of an object so that accuracy of position calculation is improved. The sensor assembly measures at least two operational characteristics and generates corresponding operational characteristic signals. A control unit monitors and compares transitions of the signals to more accurately determine direction of movement for the object.Type: GrantFiled: October 9, 2002Date of Patent: October 24, 2006Assignee: Siemens VDO Automotive CorporationInventors: Tomohiro Fukumura, Sanjaya Kumar Dash

Patent number: 6870340Abstract: A power closure system (40) for a vehicle panel (22, 24) includes position initialization techniques that ensure accurate position initialization. According to this invention, any slack in a coupling (62) between the vehicle panel and a motor (42) for moving the vehicle panel is removed prior to obtaining an initialization position reading when the panel (22, 24) is in a closed position. The inventive arrangement also includes determining a desired torque at which to operate the motor (42) during a position initialization procedure.Type: GrantFiled: December 11, 2003Date of Patent: March 22, 2005Assignee: Siemens VDO Automotive CorporationInventors: Tomohiro Fukumura, Brian J. Marlett, Sanjaya Kumar Dash

Patent number: 6840113Abstract: A pinch detection system and method controls the speed of a motor moving an object by first calculating the actual motor force and then comparing the actual motor force with a reference force value in a reference field. A pinch condition is indicated if the difference between the actual force and the reference force exceeds a selected pinch threshold. The difference is also used to update the reference field, the pinch threshold and the desired speed of the motor so that the reference field will eventually reflect the actual force profile of the object. The updated pinch threshold is also used to control the motor speed so that the pinching force remains constant regardless of the pinch threshold value.Type: GrantFiled: September 13, 2002Date of Patent: January 11, 2005Assignee: Siemens VDO Automotive CorporationInventors: Tomohiro Fukumura, Brian J.

Patent number: 6799669Abstract: A clutch control system for moving an object, such as a vehicle door, lift gate or trunk, compares the motor speed with the object speed and engages the clutch when the motor and object speeds are almost equal. Controlling engagement based on the object and motor speeds ensures smooth transitions into a power assist mode and between the power assist mode and a power release mode without causing clutch shock.Type: GrantFiled: September 13, 2002Date of Patent: October 5, 2004Assignee: Siemens VDO Automotive CorporationInventors: Tomohiro Fukumura, Brian J.
