Patent number: 8370056Abstract: A collision warning apparatus includes sensors, output devices, memory locations, a GPS device, and a processor. The processor may receive information from the sensors. The processor may also process the information to identify a detected object as a present potential collision object. The processor may compare present GPS coordinates of the vehicle with stored vehicle GPS coordinates saved in memory, to determine whether or not the present GPS coordinates correspond to stored vehicle GPS coordinates associated with a previously identified potential collision object. If the present GPS coordinates correspond to stored vehicle GPS coordinates associated with a previously identified potential collision object, the processor is operable to suppress a potential collision warning.Type: GrantFiled: August 12, 2009Date of Patent: February 5, 2013Assignee: Ford Global Technologies, LLCInventors: Roger Arnold Trombley, Thomas Edward Pilutti

Publication number: 20120330496Abstract: A method for monitoring a coolant temperature sensor of a motor vehicle is provided, wherein an actual value (TCOist=TCOSt) of a coolant temperature (TCO) is determined by a coolant temperature sensor when an internal combustion engine of the motor vehicle is started (t=tSt), and the coolant temperature sensor is diagnosed as a functional coolant temperature sensor if the actual value (TCOist) of the coolant temperature (TCO) drops briefly (tmin0) when the internal combustion engine is started (t=tSt). A controller, e.g., an engine controller, for performing such method is also provided.Type: ApplicationFiled: November 30, 2010Publication date: December 27, 2012Inventors: Gerhard Eser, Stefan Seyfferth

Patent number: 8340860Abstract: An acceleration detection device for detecting detected acceleration of a vehicle is provided with a stopped acceleration detector, an acceleration change detector, an acceleration estimating unit and a correcting unit. The stopped acceleration detector detects a detected stationary acceleration value when the vehicle is stopped on a sloping road based on an acceleration sensor signal from an acceleration sensor mounted on the vehicle. The acceleration change detector detects an acceleration change associated with the vehicle transitioning from a stationary state to a driving state on the sloping road based on the acceleration sensor signal. The acceleration estimating unit estimates an estimated stationary acceleration value based on the acceleration change that was detected by the acceleration change detector. The correcting unit corrects the detected stationary acceleration value based on a deviation between the estimated stationary acceleration value and the detected stationary acceleration value.Type: GrantFiled: December 5, 2007Date of Patent: December 25, 2012Assignee: Nissan Motor Co., Ltd.Inventors: Atsufumi Kobayashi, Tomoyuki Suzuki, Takashi Matsuda
