摘要： A hybrid transmission having an input member, an output member, and a single motor/generator is characterized by a plurality of fixed-ratio modes of operation and at least one electrically variable mode of operation. In the fixed-ratio modes of operation, the speed ratio between the input member and the output member is independent of the speed of the motor/generator. In the electrically variable mode of operation, the speed ratio between the input member and the output member is dependent upon the speed of the motor/generator.

摘要： A reinforcement and method for reinforcing a hollow tubular structure includes a first sheet of flexible fiber material impregnated with resin. The first sheet is rolled into a tubular shape and a seam is provided between first and second lateral edges of the first sheet to form a tubular reinforcement. An inflatable bladder extends through the tubular reinforcement and is inflated to press the tubular reinforcement into contact with the inside wall of the tubular structure. Curing of the resin will bond the first sheet to the inside wall to reinforce the tubular structure. The first sheet can have a region of built-up thickness to provide additional reinforcement. The seam between the lateral edges of the first sheet can be a separable seam that separates when the bladder is inflated to allow the first sheet to contact with a region of the tubular structure that is of larger circumference than the circumference of the tubular reinforcement.

摘要： A method is provided for enhancing service diagnostics utilizing service repair data of previously serviced vehicles. Service repair data of previously serviced vehicles is obtained from a memory storage device. The service data is compiled into a service diagnostic code dataset and a service labor code dataset. The service diagnostic code dataset and service labor code dataset are categorized into an electronic data table. Respective combinations are formed in the electronic data table. An aggregate count is determined for each respective combination in the electronic data table. Either of a respective diagnostic code or a respective service labor code is identified having a correlation with more than one of either service diagnostic codes or service labor codes. At least one of a service repair procedure used to repair the vehicle or a respective service diagnostic code used to identify the fault is modified in response to analyzing the respective combinations.

摘要： Methods and systems for dynamically estimating the core temperature of at least one cell in a battery. In one aspect, the method includes using a combination of estimations including one based on ohmic resistance and another based on a function of thermal energy transfer through the battery. A weighting factor may be used for each of the estimations as a way to calculating a core temperature. The estimation based on ohmic resistance may be made determined independently of a measured surface temperature of the battery or any of the cells in the battery.

摘要： A powertrain system includes a torque machine mechanically rotatably coupled via a transfer gear set to a drive wheel. The transfer gear set includes a first gear meshingly engaged to a second gear with lash angle between the first and second gears. A method for operating the powertrain system includes monitoring an output speed associated with the torque machine and a wheel speed associated with the drive wheel. A transition between a first torque transfer state and a second torque transfer state is detected, the transition including a gear lash event across the transfer gear set. An elapsed time period for completing the gear lash event across the transfer gear set during the transition between the first torque transfer state and the second torque transfer state is set, and a target output speed derived from the wheel speed during and at the end of the elapsed time period is determined. A preferred output speed profile during the gear lash event is also determined, and includes prescribed changes in the output speed associated with phase-shifting the lash angle from a minimum lash angle to a maximum lash angle. The output speed is adjusted to be substantially equal to the target output speed at the end of the elapsed time period. The torque machine is controlled to achieve the preferred output speed profile.

摘要： The method and system described herein may be used to determine a reference yaw rate (γref) for a vehicle chassis control system, and may do so across a wide spectrum of vehicle operating conditions. These conditions may include, for example, when the vehicle is being driven: at low and high vehicle speeds, in forward and reverse directions, with front-, rear- and all-wheel steering systems, according to subtle and aggressive driving maneuvers, and on roads with flat or banked surfaces, to cite a few of the potential scenarios. According to an exemplary embodiment, the method and system take into account certain tire dynamics, such as the relaxation length (λ) of the tires, when estimating the reference yaw rate (γref). Once an accurate reference yaw rate (γref) is determined, the vehicle chassis control system may use this estimate to control one or more actuators that can influence the yaw rate of the vehicle. Some non-limiting examples of systems that may include such actuators are chassis systems, brake systems, steering systems, suspension systems, safety systems, stability control systems, traction control systems, torque control systems, or any other system that can affect the vehicle yaw rate. It is also possible for the method and system described herein to determine a reference lateral velocity (Vyref) for the vehicle as well.

摘要： A robotic system includes a tendon-driven finger and a control system. The system controls the finger via a force-based control law when a tension sensor is available, and via a position-based control law when a sensor is not available. Multiple tendons may each have a corresponding sensor. The system selectively injects a compliance value into the position-based control law when only some sensors are available. A control system includes a host machine and a non-transitory computer-readable medium having a control process, which is executed by the host machine to control the finger via the force- or position-based control law. A method for controlling the finger includes determining the availability of a tension sensor(s), and selectively controlling the finger, using the control system, via the force or position-based control law. The position control law allows the control system to resist disturbances while nominally maintaining the initial state of internal tendon tensions.

摘要： One or more layers of vibration damping material are placed on one or more selected surface regions of a body portion of a vibratile metal article. The layer of damping material is covered with a thin metal sheet. The selected surface may be recessed in the body portion to receive the damping material. The covering sheet may be formed of the same metal composition as body portion, or of a compatible metal composition. The peripheral edges of the covering sheet are ultrasonically welded to the surface of the article body portion to confine the damping material against the selected surface(s) so that the damping material forms a vibration damping interface(s) with the surface(s) of the article. The damping material may function as a coulomb damping material, or a viscous damping material, or both.
