  • Publication number: 20150120107
    Abstract: A driving pattern based plug-in hybrid electric vehicle (PHEV) energy consumption preplanning process enables a PHEV trip-oriented energy management control (TEMC) to utilize scalable levels of available trip foreknowledge in order to optimize the onboard energy (fuel and electricity) usage. The preplanning process generates an optimal battery state-of-charge (SOC) depletion profile for a given trip to be traveled by a PHEV. The preplanning process may generate the battery SOC profile using a driving pattern based dynamic programming (DP) algorithm. The TEMC controls the onboard energy usage in accordance with the battery SOC profile, which is optimized for the trip. The preplanning process makes use of spatial domain normalized drive power demand (SNDP) (or S-NDP) distributions in which each set of distributions is indicative of a respective driving pattern. The trip foreknowledge is used to select the driving pattern best representative of the driving process for the trip.

  • Patent number: 8965618
    Abstract: A system and method for controlling an electric vehicle include at least one controller configured to detect an over-voltage condition when an electric-machine voltage exceeds an over-voltage threshold. In response to the over-voltage condition, the electric machine and a variable voltage controller (VVC) are disabled. Upon determining the electric-machine voltage is decreased to at least a second threshold being less than the over-voltage threshold, the controller is configured to set the VVC to a limited-operation mode. Upon determining the electric-machine voltage is decreased to at least a third threshold being less than the second threshold and the over-voltage threshold, the controller is configured to re-enable the electric machine and set the VVC to a normal-operation mode. The limited operation-mode enables the vehicle to maintain vehicle propulsion during the drive-cycle as the electric machine is recovered from a transient condition causing the over-voltage condition.

  • Patent number: 8948949
    Abstract: A torque applied to a one-way clutch when a first motor generator and second motor generator are operated in a motor generator drive mode is restrained or prevented from becoming excessively high by setting a first motor generator sharing ratio in response to a driving torque target for the vehicle, by controlling operation of the first motor generator in response to a first motor generator first sharing ratio when vehicle vibrations due to cogging torque are likely to take place, and by reducing the torque from the first motor generator when the driving torque target is large. Torque applied to the one-way clutch which otherwise would become excessively high immediately after engine shutdown, is restrained or prevented by reducing the torque from the first motor generator in response to a second motor generator second sharing ratio when engine downtime is short.

  • Publication number: 20150032301
    Abstract: A method of storing energy produced by a mobile vehicle is disclosed. The method may include receiving information on a vehicle trip profile. An electrical mode of a traction motor configured for propelling the vehicle may be changed from a motor mode where the traction motor receives electrical power to a generator mode where the traction motor produces electrical power when the trip profile indicates a charging opportunity. The method may further include directing energy generated by the traction motor in generator mode to a first tier of one or more energy storage devices with first rate-of-energy-absorption capabilities. A second tier of one or more energy storage devices with second rate-of-energy-absorption capabilities slower than the first rate-of-energy-absorption capabilities may then be charged with energy from the first tier energy storage devices. The charging of the second tier energy storage devices may continue when the traction motor is no longer producing electrical power.
