  • Publication number: 20110238257
    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: 20100288570
    Abstract: A hybrid propulsion system and a method of controlling same are provided. The hybrid propulsion system includes an internal combustion engine having a fluid lubrication and control system. The hybrid propulsion system also includes an engine oil pump arranged externally with respect to the engine and configured to maintain fluid pressure to the lubrication and control system when the internal combustion engine is shut off. Additionally, the hybrid propulsion system includes a motor/generator and a transmission in operable communication with the internal combustion engine. The transmission includes a transmission oil pump arranged externally with respect to the transmission and configured to maintain fluid pressure to the transmission when the engine is shut off. Furthermore, the hybrid propulsion system includes an auxiliary motor driving the externally arranged engine oil pump and the externally arranged transmission oil pump.

  • Publication number: 20100217470
    Abstract: An auxiliary pump diagnostic system includes a slip determination module and a fault determination module. The slip determination module determines slip of a torque converter based on an engine speed and a transmission input speed. The fault determination module diagnoses a fault in an auxiliary pump based on the slip of the torque converter.

  • Publication number: 20100090527
    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.

  • Publication number: 20090255741
    Abstract: A belt alternator starter (BAS) system for a hybrid vehicle may include a first pulley, a first belt, a motor generator unit (MGU), a second pulley, a second belt, and a first clutch. The first belt encircles the first pulley and a crankshaft pulley of an internal combustion engine. The MGU includes the second pulley and functions as an electric motor when the engine is started and as a generator for charging a battery when the engine is running. The second belt encircles the second pulley and at least one drive pulley of an accessory unit. The first clutch couples/decouples the crankshaft pulley to/from the second pulley depending on operation of the engine.
