Patent number: 8232792Abstract: A system and method for controlling the output voltage of a power supply that includes a control section and an interconnect section having an output point. A voltage regulator provides a control section voltage, and a current measurement device measures a control section current and generates a current signal. A controller receives the current signal and a voltage command signal representing a desired output voltage at the output point of the interconnect section. The controller generates an adjusted voltage command signal based on the voltage command signal representing the desired output voltage, the current signal, a control section internal resistance and an interconnect section external resistance. The voltage regulator receives the adjusted voltage command signal and provides a control section voltage based thereon in order to supply an output voltage at the output point that is substantially equal to the desired output voltage.Type: GrantFiled: August 13, 2010Date of Patent: July 31, 2012Assignee: Lear CorporationInventors: Richard Hampo, Benjamin D.

Publication number: 20070016340Abstract: A control system, method and article allows a monitoring module to monitor operation of a main controller in an electric drive, by providing questions and evaluating the accuracy and/or timeliness of responses from the main controller. Upon detection of an excessive number of incorrect or late responses, the monitoring module can shutdown operation, and may provide an alternative communications path, thereby preventing corrupt data from reaching a vehicle network, while providing communications for diagnostic and recovery such as by provision of new software or firmware instructions. The main controller may monitor the operation of the monitoring module, taking appropriate action if a fault is detected. Disabling a supply of power to a traction motor may be based on current operating conditions, such as speed.Type: ApplicationFiled: June 29, 2006Publication date: January 18, 2007Inventors: Christophe Soudier, Bing Cheng, Steven Kowalec, Venkatapathi Nallapa, Richard Hampo
