Patent number: 9322381Abstract: A remote start vehicle system for a vehicle is provided. The system includes a remote start requester configured to request that the engine be started. The remote start requester is operable to request that the engine be started when the remote start requester is located outside of the vehicle. A control module is configured to cause the engine to be started upon request from the remote start requester. A sensor assembly is configured to sense a neutral gear state of the transmission, where the neutral gear state indicates whether the transmission is in neutral. The sensor assembly is configured to communicate the neutral gear state to the control module. The control module is configured to prevent the engine from being started if the neutral gear state indicates that the transmission is not in neutral. A method of remotely starting an engine is also provided.Type: GrantFiled: March 7, 2013Date of Patent: April 26, 2016Assignee: GM Global Technology Operations Inc.Inventors: William L.

Patent number: 9322632Abstract: A linear position sensor assembly having a magnetic shield minimizes interference (noise) from adjacent electrical and electromagnetic devices, particularly solenoids. The sensor assembly includes a permanent magnet linear contactless displacement (PLCD) sensor comprising a pair of magnetic field sensors which are spaced apart by a member of high magnetic permeability such as a metal bar. The sensors and metal bar are enclosed, i.e., surrounded on three sides, by a cover or shield of high magnetic permeability material such as steel or mu metal, for example. A permanent magnet is disposed in sensed proximity to the sensors and translates with a clutch actuator component. When the clutch actuator component translates axially, the two field sensors provide a signal to associated electronics having high linearity, low noise and no deadband.Type: GrantFiled: August 31, 2012Date of Patent: April 26, 2016Assignee: GM Global Technology Operations Inc.Inventors: Xinyu Zhou, Moussa Ndiaye, Michael Partridge, Xu Han, Michael McLeod

Patent number: 8682956Abstract: An onboard computer system including instructions causing a processor to store a first-user media profile indicating media preferences of a user. The processor also determines that the vehicle is encountering a second vehicle and receives a second-user media profile. The processor also evaluates the profiles to determine whether the profiles bear a predetermined similarity and, in response to determining the similarity exists, identifies recommended media, based on characteristics of the profiles, and initiates provision of the recommended media to one of the users of the first vehicle and the user of the second vehicle.Type: GrantFiled: June 9, 2011Date of Patent: March 25, 2014Assignee: GM Global Technology Operations, IncInventors: Fan Bai, Donald K.

Publication number: 20120187916Abstract: The described method and system provides for dynamic adjustment of the lower charge threshold of an electrically-powered vehicle to allow a fuel-depleted vehicle also low on battery charge to continue to be operated. The vehicle's telematics unit monitors the fuel level and charge level via the vehicle bus or other vehicle resources to determine if the vehicle is running low on fuel and electric charge. If the telematics unit determines that the fuel is depleted and the charge level is approaching, meets or falls below the lower threshold, the telematics unit communicates the vehicle fuel status and vehicle position to a call center along with vehicle identification data. The call center determines the amount of charge required to reach one or more local fueling stations or other points of interests and propose destination recommendations to the driver. The driver may then select one of the recommendations, and the call center transmits a new lower charge threshold to the vehicle.Type: ApplicationFiled: January 20, 2011Publication date: July 26, 2012Applicants: GM Global Technology Operations, Inc., General Motors LLCInventors: Armando A.

Publication number: 20120117951Abstract: A control system for a vehicle includes a location identification module, an adjustment triggering module, and an adjustment module. The location identification module identifies a location where an engine of the vehicle is expected to be shut down and later re-started with at least one temperature within a predetermined range of an ambient temperature at the time of the re-start. The adjustment triggering module generates a triggering signal when a vehicle location provided by a global positioning system (GPS) is less than a predetermined distance from the identified location. The adjustment module selectively one of increases and decreases a rate at which a dosing agent is injected into an exhaust system, upstream of a selective catalytic reduction (SCR) catalyst, when the triggering signal is generated.Type: ApplicationFiled: November 12, 2010Publication date: May 17, 2012Applicant: GM Global Technology Operations, Inc.Inventor: Adam Vosz
