Publication number: 20170072921Abstract: A method, and associated system and computer program product, for managing braking of a moving vehicle. A speed and deceleration of the moving vehicle are monitored. External and/or internal conditions relating to the moving vehicle and/or the vehicle's driver are detected. A hardware processor: calculates a braking distance for the moving vehicle for the detected external and/or internal conditions from the monitored speed and deceleration of the moving vehicle; determines a spacing distance between the moving vehicle and a second vehicle ahead of the moving vehicle; adds a cascading response distance to the calculated braking distance for a third vehicle ahead of the second vehicle; and determines that the calculated braking distance is greater than the determined spacing distance. An output is generated in response to the determination that the calculated braking distance is greater than the obtained spacing distance.Type: ApplicationFiled: September 15, 2015Publication date: March 16, 2017Inventors: Christel Amato, Aaron K.

Publication number: 20170072922Abstract: A method is provided for estimating a road surface condition by accurately determining whether or not there has been any large input to a tire without increasing the number of sensors. An acceleration sensor is disposed on the tire to detect the vibration of the tire in motion. The positions of leading end point and trailing end point of tire contact patch are estimated from the peak positions appearing in the time-variable waveform of the vibration. At the same time, the contact time, extra-contact time, and revolution time of the tire are calculated from the estimated positions of leading end point and trailing end point. Then using one or more of the calculated data, it is determined whether or not the estimated positions of leading end point and trailing end point are equal to the actual positions of leading end point and trailing end point. And if the result of the leading and trailing position determination is “incorrect estimation”, the estimation of a road surface condition is not performed.Type: ApplicationFiled: January 5, 2015Publication date: March 16, 2017Applicant: BRIDGESTONE CORPORATIONInventor: Yasushi HANATSUKA

Publication number: 20170072965Abstract: The present disclosure provides a method for an intelligent quick bed-in of an automatic transmission comprising the steps of operating the vehicle according to a predetermined protocol so that the powertrain controller can learn about powertrain variations and adapt operation of the transmission; obtaining feedback information regarding operator performance of the method and vehicle performance during the method; determining whether the bed-in method was successful by the level of run-up or tie-up, by whether the powertrain controller was allowed to adapt, or by the level of powertrain controller adaptation; and completing the bedding-in process. The method being capable of reducing the time required for a bedding-in process, while improving the reliability of the bedding-in process.Type: ApplicationFiled: September 15, 2015Publication date: March 16, 2017Applicants: Hyundai America Technical Center, Inc., Hyundai Motor Company, KIA Motors CorporationInventors: Matthew Betts, BeongYeol YOU, Anthony Golletti, Thomas Kieffer

Publication number: 20170072966Abstract: A vehicle includes a subsystem conditioner and a controller. The controller is programmed to, in response to a difference between user specified and learned times of day being greater than a threshold, activate the conditioner a predetermined time before each of the times of day. The controller is also programmed to, in response to the difference being less than the threshold, activate the conditioner the predetermined time before the specified time of day but not the learned time of day.Type: ApplicationFiled: September 15, 2015Publication date: March 16, 2017Inventors: Bryan Michael BOLGER, Angel Fernando PORRAS

Publication number: 20170072968Abstract: An operation system for vehicle includes a longitudinal member, a movement detector, and a controller. The movement detector is provided to a tip of the longitudinal member and detects, in a sensing space set so as not to detect movement of hands or fingers of an operator who holds a steering wheel without intention of operating an in-vehicle device, an operation form when the operator operates the in-vehicle device. The controller transmits a command to the in-vehicle device based on an output signal of the movement detector. The movement detector includes a sensor having a light-emitting unit and a light-receiving unit, and a housing. The housing includes a non-transmission part and a transmission part that transmits light so that the light forms the sensing space.Type: ApplicationFiled: September 8, 2016Publication date: March 16, 2017Inventor: Takashi Azuchi

Publication number: 20170072970Abstract: A system for remotely controlling a fuel-supply system associated with a locomotive includes multiple detectors positioned on board the locomotive and the fuel-supply system. The detectors are configured to generate a warning signal upon detection of an abnormality in the operation of at least one of: the locomotive and the fuel-supply system. The system further includes a controller that is remotely located and communicably coupled to each of the detectors. The controller is configured to receive the warning signal from at least one of the detectors, the warning signal being indicative of the abnormality. The controller is also configured to provide, at a graphical user interface (GUI), a list of user-allowable actions based on a type of abnormality detected. The controller is then configured to operably actuate a relay associated with the fuel supply system on receiving a chosen user-allowable action from the list of user-allowable actions.Type: ApplicationFiled: September 11, 2015Publication date: March 16, 2017Applicant: Electro-Motive Diesel, Inc.Inventors: Alexander Shubs, James David Seaton, David Matthew Roenspies
