  • Patent number: 8193915
    Abstract: A vehicle transceiver module is provided for use in a synchronous communication system including the vehicle transceiver module and one or more key fobs, each of the key fobs including a key fob transceiver for transmitting and receiving signals. The vehicle transceiver module includes transceiver circuitry, a controller, a storage device and power control circuitry. The transceiver circuitry receives the signal transmitted by the key fob transceiver and provides it to the controller. The controller is coupled to the transceiver for determining an offset value associated with one of the key fobs in response to an offset time duration between a reception time of the signal from the key fob and a first expected reception time of the signal from the key fob. The storage device is coupled to the controller for receiving the offset value associated with the key fob from the controller and stores the offset value along with information identifying the key fob.

  • Publication number: 20120136532
    Abstract: A system and method is provided to index the door window glass of a vehicle to disengage the glass from the window sealing interface prior to opening the door. A door latch including an unlatching lever selectively connectable to the inside and outside door handles is configured such that moving either handle to actuate the latch causes an initial change in the position of the unlatching lever prior to latch release. A sensor in the latch detects the initial change in position of the unlatching lever and signals an indexing mechanism to move the glass to the indexed position prior to latch release, such that the glass does not substantially interfere with the sealing interface when the door is moved from a closed position. The system may be configured such that the door lock mechanism must be unlocked prior to the indexing mechanism moving the window to an indexed position.

  • Publication number: 20120133369
    Abstract: A method for estimating the capacity of a vehicle battery while in service. The method includes providing a previous battery state-of-charge, battery temperature and integrated battery current amp-hours, and determining that battery contactors have been closed after they have been opened and disconnected from a load. The method determines if the battery has been at rest for a long enough period of time while the contactors were open, where the battery rest time is based on battery temperature, and determines an initial battery voltage from a last time step when the battery contactors were closed prior to the contactors being open during the battery rest time. The method determines a present battery state-of-charge from the initial battery voltage and the battery temperature and calculates the battery capacity based on the battery integrated current amp-hours divided by the difference between the present battery state-of-charge and the previous battery state-of-charge.

  • Publication number: 20120136545
    Abstract: A method is provided for operating a motor vehicle. The method includes, but is not limited to determining whether the roadway in the area of the motor vehicle forms an approach to another roadway. If it is determined that the roadway forms an approach to another roadway, a first lane of the roadway in which the motor vehicle is located is determined with data of an optical camera of the motor vehicle. In addition, a direction of travel along in the first lane is determined and determined whether the motor vehicle is traveling in the direction opposite the direction of travel. If it is determined that the motor vehicle is traveling in the direction opposite the direction of travel, a first warning message is output and/or at least one apparatus (e.g., braking apparatus, a drive apparatus, and a steering apparatus) is actuated.
