  • Patent number: 9440636
    Abstract: A vibration damping control apparatus is mounted on a hybrid vehicle provided with an engine and a motor generator coupled with the engine. The vibration damping control apparatus (i) calculates pulsating torque of the engine and inertia torque of the engine, (ii) sets, as consumption torque, a value obtained by subtracting the inertia torque from the pulsating torque, (iii) sets, as shaft torque of an output shaft of the engine, a value obtained by subtracting the consumption torque from base torque of the motor generator, (iv) calculates vibration damping torque which is torque for suppressing a variation in the shaft, and (v) controls the motor generator such that torque outputted from the motor generator is a sum of the base torque and the vibration damping torque.

  • Publication number: 20150307080
    Abstract: A control system is provided in a vehicle including an internal combustion engine, a second MG, and a first MG. The control system starts the engine when required vehicle output becomes equal to or larger than a predetermined start threshold value, and stops the engine when the required vehicle output becomes equal to or smaller than a predetermined stop threshold value. The control system controls the engine so that output power equal to or larger than a predetermined output lower-limit value is generated, during a period from the time when the required vehicle output becomes equal to or larger than the predetermined start threshold value to the time when the required vehicle output becomes equal to or lower than the predetermined stop threshold value. The predetermined output lower-limit value is set to the predetermined start threshold value used when the required vehicle output becomes equal to or larger than the predetermined start threshold value.

  • Patent number: 8768202
    Abstract: An image forming apparatus includes a first moving member pressed and moved by an openable/closable member when the member is opened. A cartridge is switched from being positioned in an image forming position to a state where the positioning is released. A second moving member is pressed and moved by the openable/closable member when the member is opened, and the exposure member is moved from an exposure position to a retracted position. When the cartridge is released, a reaction force applied from the first moving member to the openable/closable member reaches a first peak. When the exposure member is moved to the retracted position, a reaction force applied from the second moving member to the openable/closable member reaches a second peak. Timing of the first peak is different from timing of the second peak.

  • Patent number: 8565930
    Abstract: An ECU operates a charging unit such that a power storage device is charged by an electric power from a power supply. When a vehicle moves while charging the unit charges the power storage device, the ECU stops charging the unit to discontinue the charging of the power storage device. The ECU diagnoses a state of the charging unit after the charging of the power storage device is stopped. The ECU determines whether the charging of the power storage device is able to be resumed based on the diagnostic result. When determining that the charging of the power storage device is able to be resumed, the ECU resumes the charging of the power storage device by resuming the operation of the charging unit.
