  • Patent number: 9032837
    Abstract: A pendulum absorber system attenuates torsional vibrations within a drive train of a vehicle. The system can be incorporated between an engine and an automatic transmission, for example, within a flex plate assembly attached to an engine's crankshaft, within a pump housing cover of a torque converter, or as a stand-alone unit between a flex plate assembly and a torque converter. The system includes at least one pendulum weight that dynamically moves along a predetermined path in response to variations in rotational velocities of a housing of the system and that is tuned to attenuate excitation of torsional vibrations within the drive train. A limiter assembly, which can include multiple limiters, is provided within the system for stopping movement of the weight when it reaches endpoints of the predetermined path, by mechanically impeding further movement at both of a first and second end of the weight.

  • Patent number: 8994689
    Abstract: A capacitive switch assembly for controlling power windows of an automotive vehicle has a plurality of window select capacitive sensors with a respective window select capacitive sensor for selecting a respective power window to be opened or closed. The capacitive switch assembly also includes a capacitive actuator including gesture responsive capacitive sensors responsive to an open gesture and a close gesture made by a user with a finger on a gesture pad of the capacitive actuator. The gesture responsive capacitive sensors are located at locations on the gesture pad so that the open and close gestures mimic the way in which a user moves an actuator of a mechanical switch to open and close a window. The capacitive switch assembly may include a hot button that enables and disables the power windows.

  • Patent number: 8981918
    Abstract: A warning system for a vehicle having an air suspension system can include an indicator, an event data recorder, and a controller. The controller can be configured to determine a load on a front axle and a rear axle when the vehicle is in a static condition and compare the determined load on the front and rear axles to a predetermined load threshold for each of the front and rear axles. A warning signal can be provided to the indicator indicative of at least one of the determined loads exceeding the corresponding predetermined load threshold upon the controller determining one of the determined loads exceeds the corresponding predetermined load threshold. Data indicative of at least one of the determined loads exceeding the corresponding predetermined threshold can be communicated to the event data recorder.

  • Patent number: 8977429
    Abstract: A system for shifting a vehicle's transfer case into or out of the neutral position, using an electronic vehicle information center. The system comprises a transfer case control module connected to a transfer case and an electronic vehicle information center connected to the transfer case control module. The electronic vehicle information center instructs the transfer case control module to shift the transfer case into or out of the neutral position by detecting an input signal request from a control panel to shift the transfer case into or out of a neutral position, and sending an instruction signal to the transfer case control module to shift the transfer case into or out of the neutral position.

  • Patent number: 8977478
    Abstract: A method of verifying a default state of a control parameter in an automobile engine includes checking engine controller performance with the control parameter in both a default state and an alternate state. The results of the tests are then compared to verify which state is the appropriate state for the particular engine being tested. A third engine controller performance check can be made to ensure that the controller and engine perform in a repeatable manner prior to setting the state of the control parameter.

    Abstract: A system for a vehicle may include a motor assembly, a wiper and a switch. The motor assembly may be mounted to a spare tire carrier on a tailgate of the vehicle and may include an output shaft that is rotatable relative to the spare tire carrier. The wiper may be attached to the output shaft for rotation with the output shaft relative to a rear window pane of the vehicle. The switch may be electrically connected to the motor assembly and may be operable to allow electrical current to reach the motor assembly when the wiper is in contact with the rear window pane. The switch may be operable to prevent electrical current from reaching the motor assembly in response to the wiper and the rear window pane being spaced apart from each other.
