  • Publication number: 20180155967
    Abstract: The present invention discloses a method and system for unlocking vehicle engine cover. Method comprising: acquiring an action signal transmitted from an action sensor, and executing an action signal judging step; executing an unlocking step if the received action signal matches a preset unlock action signal, otherwise not executing the unlocking step, the unlock action signal is a combination of a signal or a plurality of consecutive signals; unlocking step: sending an unlock signal to an engine cover lock, wherein the unlock signal is used to control the engine cover lock to perform an unlock operation on a vehicle engine cover. The present invention detects an action signal from an action sensor, and controls whether or not to unlock the vehicle engine cover by matching the action signal with a preset unlock action signal. So users do not need to enter into the passenger compartment for unlocking. The operation is both convenient and rich sense of technology.

  • Patent number: 8893868
    Abstract: A viscous fluid clutch for use as a clutch for a cooling fan for a vehicle, the clutch includes an input shaft, a rotor assembly, a first housing portion, a second housing portion, a coil assembly, and a brush box. The rotor assembly is coupled to the input shaft. The first housing portion is coupled to the second housing portion and the second housing portion is rotatably disposed on the input shaft. The first and second housing portions define a fluid reservoir for receiving the rotor assembly and a viscous fluid, preferably of the magnetorheological type. The coil assembly is coupled to the first housing portion. The brush box is operably coupled to the coil assembly. When the coil assembly is energized by the brush box, a magnetic field is created that acts upon the magnetorheological fluid to vary the torque transfer of the input shaft to the housing and the fan connected thereto.

  • Publication number: 20110069680
    Abstract: A system and method for executing network acquisition employ a triggered scan for network acquisition regardless of the recorded optimal nature of the current network. In general, when one or more predefined conditions occur, a network scan is initiated to identify another network, if any, that is more optimal than the current network. Example trigger conditions include failed registration attempts, exceeding a predetermined distance threshold, entry to or exit from a pre-determined region, excess CDMA Chip delay, and others. Triggers may be used singly or in Boolean combinations. In this way, network scanning occurs when it may be beneficial, but will not be initiated too frequently or in situations where connectivity may not actually be suboptimal. This triggered scan provides improved connectivity, and can allow the device to make and receive calls in locations where it would otherwise not have been possible.

  • Publication number: 20110015854
    Abstract: A method is provided for managing map data for intersections having stop sign indicators. A request is initiated for turn-by-turn navigation instructions for a destination from a vehicle to an infrastructure. A turn-by-turn navigation maplet is transmitted from the infrastructure to the vehicle. A geographical region associated with the received turn-by-turn navigation maplet is identified. A determination is made whether stop sign locations already retained within a memory of the vehicle relate to the identified geographical region. The vehicle on-board device requests stop sign maplets for the identified geographical regions from the infrastructure if the stop sign locations retained within the memory of the vehicle do not relate to the identified geographical region. The stop sign maplets are transmitted for the identified geographical region from the infrastructure to the vehicle. The stop sign maplets relate to stop sign intersection data within the identified geographical region.

  • Publication number: 20110010171
    Abstract: A system and method for providing speech recognition functionality offers improved accuracy and robustness in noisy environments having multiple speakers. The described technique includes receiving speech energy and converting the received speech energy to a digitized form. The digitized speech energy is decomposed into features that are then projected into a feature space having multiple speaker subspaces. The projected features fall either into one of the multiple speaker subspaces or outside of all speaker subspaces. A speech recognition operation is performed on a selected one of the multiple speaker subspaces to resolve the utterance to a command or data.

  • Patent number: 7854467
    Abstract: An airflow control device comprises a body and an active material in operative communication with the body. The active material, such as shape memory material, is operative to change at least one attribute in response to an activation signal. The active material can change its shape, dimensions and/or stiffness producing a change in at least one feature of the airflow control device such as shape, dimension, location, orientation, and/or stiffness to control vehicle airflow to better suit changes in driving conditions such as weather, ground clearance and speed, while reducing maintenance and the level of failure modes. As such, the device reduces vehicle damage due to inadequate ground clearance, while increasing vehicle stability and fuel economy. An activation device, controller and sensors may be employed to further control the change in at least one feature of the airflow control device such as shape, dimension, location, orientation, and/or stiffness of the device.

  • Publication number: 20100256903
    Abstract: A system and method for generating road routing information and using that information in providing navigation services to drivers. The method involves collecting off-route data indicative of occurrences of vehicles deviating from a planned route. Clusters of related off-route occurrences can then be identified based on the off-route data, and for each of at least some of the clusters, a road condition (e.g., closed, new, shifted, congested) is determined based on attributes of the cluster. Thereafter, road routing information is generated based on the determined road condition. Various routing actions can then be carried out, such as updating map data so that the system can provide drivers with improved route guidance.

    Abstract: A system and method for activating an inactive telematics unit provides a group of communications functions to the telematics unit. Initially, a call is received at a call center from a user of the telematics unit, through which subscriber information is obtained. An account data set is created at the call center based on the subscriber information and the call center advisor sets an activation trigger in the telematics unit. When the trigger condition occurs, the telematics unit places a VDU call to the call center. The call center then automatically activates and configures the telematics unit via the VDU call to provide the group of one or more communications functions.
