Abstract:

A bracket and nut assembly including a bracket having a first end and second end. The first end includes a first substantially planar portion spaced apart from and positioned substantially parallel to a second substantially planar portion. A third portion interconnects the first and second portions. A first aperture extends through the first portion and a second aperture extends through the second portion. The first and second apertures are axially aligned with one another. A nut includes a substantially cylindrical hollow body having flats, a first end and a second end. A flange radially extends from the first end. The flange is captured between the first portion and the second portion of the bracket such that the nut is operable to translate and rotate relative to the bracket.

US Classification:

701102, 701115, 701 22, 340439

Abstract:

A fuel savings informational system is provided for implementation on an alternative fuel vehicle the operation of which may be characterized by a first plurality of fixed parameters and a second plurality of variable parameters. The system compares the fuel consumption of the alternative fuel vehicle to that of a virtual comparison vehicle characterized by a third plurality of fixed parameters, and comprises a plurality of sensors for monitoring the second plurality and a processor coupled thereto. The processor is configured to recall the first and third pluralities, capture data corresponding to the second plurality, and determine the fuel consumption of the alternative fuel vehicle from the second plurality. The processor is further configured to estimate the fuel consumption of the comparison vehicle from the first, second, and third pluralities, and compare the fuel consumption of the alternative fuel vehicle to the estimated fuel consumption of the comparison vehicle.

International Classification:

H02J 7/04
H02J 7/16

US Classification:

320150, 320104, 320153, 320144

Abstract:

Embodiments include methods for charging a battery of an electrical system. The electrical system includes the battery, a battery charger, and a controller. The battery charger is adapted to produce an output power in response to a control signal from the controller. The controller is adapted to control a battery charging process by determining a temperature of the battery pack, determining a voltage setpoint for the battery charger based on the temperature, and providing the control signal to the battery charger. According to an embodiment, when the temperature of the battery exceeds a first temperature value, the battery charging process is temporarily suspended prior to satisfying a charging termination criterion. Determining the temperature of the battery is repeated, and when the temperature of the battery is less than a second temperature value, the battery charging process is resumed.

International Classification:

H01M 10/50
H01M 10/42

US Classification:

429 50, 429120

Abstract:

A method for conditioning an energy storage system for a vehicle located in a geographic area includes the steps of obtaining data pertaining to an external temperature of the geographic area, measuring a temperature of the energy storage system, heating the energy storage system if the temperature is less than a first predetermined threshold, and cooling the energy storage system if the temperature is greater than a second predetermined threshold. The first predetermined threshold is dependent upon the external temperature. The second predetermined threshold is also dependent upon the external temperature.

US Classification:

702 63, 324427

Abstract:

Methods and systems for estimating remaining life of an automotive propulsion battery are provided. A total usable capacity of the battery is calculated based on cycling the battery. A first component of degradation is calculated based on driving throughput of the battery. A second component of degradation is calculated based on aging of the battery. The total degradation is calculated based on the sum of the first component and the second component of degradation.

Abstract:

Methods and apparatus are provided for torque control in an electric all wheel drive (e AWD) vehicle. The apparatus is a system having at least one propulsion system capable of determining a desired torque command and torque capability data for a primary and secondary axle. Also included are one or more active chassis systems capable of providing chassis system data and a processor coupled for processing the desired torque command, the torque capability data and the chassis system data to provide a maximum torque limit and a minimum torque limit for the secondary axle. In this way, at least one propulsion system processes the desired torque signal and the maximum torque limit and the minimum torque limit to provide an electric motor torque command and an engine torque command for the eAWD vehicle. A method for torque control in an eAWD vehicle is also provided.

International Classification:

B60K 4108

US Classification:

74872

Abstract:

A throttle follower controller for establishing a release throttle position upon the release of the throttle by the vehicle operator which is maintained at a specified value for a predetermined time if the vehicle transmission is experiencing an upshift or if an upshift will occur upon the release of the throttle to provide for a smooth upshift. Upon completion of the upshift or if no upshift will occur upon release of the throttle, a controlled transition of the throttle angle to a predetermined lower coastdown value is established to prevent drive-on while preventing a sudden harsh drive line jerk upon release of the vehicle throttle.
