  • Publication number: 20200070666
    Abstract: A vehicle including a primary coil, a secondary coil, and a controller is provided. The controller may be programmed to position the secondary coil relative to a primary coil by, responsive to increases in voltage induced in the secondary coil by the primary coil, commanding the vehicle forward. The controller may be further programmed to, responsive to decreases in the voltage immediately following increases, commanding the vehicle forward a predetermined distance. The controller may be further programmed to, responsive to decreases in the voltage immediately beyond the predetermined distance, command the vehicle reverse. The controller may be further programmed to position the secondary coil relative to the primary coil by, responsive to increases in the voltage during reverse movement of the vehicle, command the vehicle reverse.

  • Patent number: 9931954
    Abstract: A park assist system may, in response to receiving a signal indicating that a remote inductive charge source is within a vicinity of a vehicle, transition from a park assist mode to a wireless charging mode. During the wireless charging mode, the park assist system generates instructions to assist a driver in positioning the vehicle relative to the inductive charge source.

  • Patent number: 9203068
    Abstract: A battery pack for a vehicle may include a cell array defining an upper surface and a housing defining a raised portion extending along and above a length of the array such that the raised portion and upper surface define a vent manifold therebetween which may be configured to collect gases generated by the array. The housing may define a discharge opening configured to allow gases to exit the manifold. A pair of end plates may be disposed at opposing ends of the array. One of the end plates may define a pass through portion in at least partial registration with the discharge opening. An outlet tube may be configured to facilitate fluid communication between the vent manifold and exterior of the vehicle. The battery pack may also include spacers located between upper edges of adjacent cells and may be configured to prevent cooling gases from entering the vent manifold.

  • Patent number: 9026393
    Abstract: A High Voltage Interlock Strategy (HVIS) uses feedback current to detect cable connectivity status for a high-voltage cable configured to connect a power conversion circuit with a remote permanent magnet synchronous machine (PMSM). One or more feedback factors are calculated based on detected feedback current. Various algorithms for calculating a feedback factor, and for determining connectivity status based on calculated feedback factors, can be practiced, according to the PMSM operational mode. Fault detection action can be performed in response to detecting a cable disconnect. The HVIS can be implemented by software, making it a safe, economical solution for cable connectivity detection.

  • Patent number: 9007031
    Abstract: A power source is electrically connected with a battery and an electrical load. The power source has an output voltage and provides current for the battery and electrical load. A charging voltage for the battery is determined based on temperature of the battery. An offset voltage is determined based on the provided current to the battery. The output voltage is determined based on the charging and offset voltages.

  • Publication number: 20130238426
    Abstract: A device transmits a first advertisement to a client device of a user; updates an indicator, associated with the user, to indicate that the device transmitted the first advertisement to the client device; and receives a request from a user device of the user. The request includes an identifier associated with the user. The device further determines, based on the identifier, that the user of the user device is also the user of the client device; determines, based on the identifier and the indicator, that the device transmitted the first advertisement to the client device; selects a second advertisement for the user device based on the request; and transmits the second advertisement to the user device. The first advertisement and the second advertisement advertise a particular item.
