  • Patent number: 9180765
    Abstract: A hybrid vehicle includes an electric motor with a rotatable rotor. A centrifugally-actuated clutch has a first rotatable member, a second rotatable member, and at least one actuator member attached to the first rotatable member. One of the first rotatable member and the second rotatable member is operatively connected to the wheels. The other of the first rotatable member and the second rotatable member is operatively connected to the rotor. The actuator member is configured to transfer torque between the first rotatable member and the second rotatable member by an amount that decreases due to centrifugal force acting on the actuator member as a rotational speed of the first rotatable member increases. A method of control is also provided.

  • Patent number: 8771136
    Abstract: A powertrain for a vehicle includes an engine and a transmission having an input member, an output member, and a neutral state in which torque is not transmitted from the input member to the output member. A first motor/generator is coupled to the engine. A second motor/generator is coupled with vehicle wheels directly or indirectly through the transmission. The first motor/generator acts as a generator when powered by the engine to provide electric power to the second motor/generator. The second motor/generator acts as a motor when receiving electric power from a battery or from the first motor/generator. A shift selector is moved by a vehicle operator to establish an electric propulsion mode in which the transmission is in the neutral state and the second motor/generator functions as a motor.

  • Patent number: 8346420
    Abstract: A method is provided for generating projected vehicle energy consumption information for a second vehicle using statistical information describing a driving history of a driver of a first vehicle. Statistical information is determined from collected vehicle performance values while the driver operates the first vehicle, and is archived in at least one memory location. The archived statistical information is correlated with a vehicle specification describing a performance capability of the second vehicle. A message is processed that includes the projected vehicle energy consumption information for the second vehicle. A vehicle is provided for generating the projected vehicle energy consumption information, and includes at least one memory location, sensors for measuring vehicle performance values of the vehicle describing a driver history of the first vehicle, and a controller adapted for automatically determining the statistical information. A controller is also provided adapted for executing the method.

  • Publication number: 20120233077
    Abstract: A method for reserving a vehicle charging station includes receiving a desired destination, and automatically verifying the availability of a designated station at an expected arrival time. The method further includes reserving the designated station when the designated station is available at the expected arrival time, and transmitting an electronic token to the client device. The token confirms the reservation and uniquely identifies the vehicle. A system for reserving the station includes a server in communication with the station, and with a client device configured for communicating a desired destination to the server. The server automatically verifies the availability of the designated charging station at an expected arrival time at the desired destination, reserves the designated station when it is available at the expected arrival time, and then generates and transmits the token to the client device.

  • Publication number: 20120158227
    Abstract: An electric vehicle maximizes an electric-only driving range. The vehicle includes a power source, an energy storage device, an auxiliary power unit (APU), and a controller. The power source propels the vehicle. The energy storage device supplies electricity to the power source. The APU supplies supplemental energy to the power source. The controller operates the vehicle in an electric-only driving mode to propel the vehicle and obtains a state of charge (SOC) of the energy storage device. The vehicle and at least one charging station are located. The controller determines a minimum required SOC of the energy storage device for the vehicle to reach at least one charging station. The controller activates the APU to operate the vehicle when the SOC of the energy storage device is below the minimum required SOC of the energy storage device for the vehicle to reach the location of at least one charging station.

  • Patent number: 8039988
    Abstract: A solar powered ventilation system for regulating the interior temperature of a motorized vehicle and a method of controlling the same is provided. The vehicle includes a battery pack in electrical communication with at least one motor assembly that is selectively operable to propel the vehicle. The solar powered ventilation system includes a solar panel in electrical communication with a fan and the battery pack. The method includes: determining if sufficient solar load is available; if so, determining the current vehicle power mode; determining if the current battery pack temperature is greater than a threshold battery pack temperature if the vehicle is in “off” or “accessories on” mode; and commanding the solar powered ventilation system to modify the interior temperature of the vehicle to thereby decrease the temperature of the battery pack if the current battery pack temperature is greater than the threshold battery pack temperature.
