  • Patent number: 7808659
    Abstract: In order to transmit fixed-image/text drawing data to print a character contained in a fixed image placed at a predetermined position of paper and body-text drawing data to print a body (text) image in a body, a host apparatus gives the unique download (DL) font ID using a numeric value in different numeric area to each text drawing data stored in external memory attached to a printer. The printer stores the text drawing data identified by the DL font ID in the external memory and upon reception of an image formation command, the printer reads the text drawing data from the external memory and forms an image. Thereby, appropriate text drawing data can be used to print.

  • Patent number: 7784575
    Abstract: A hybrid vehicle drive control system is configured to perform engine startup when switching from an electric drive mode to a hybrid drive mode, without creating a sense of output torque loss. In particular, a controller selectively controls a first clutch disposed between the engine and the motor/generator and a second clutch disposed between the motor/generator and a drive wheel to switch between an electric drive mode in which the first clutch is released and the second clutch is engaged, and a hybrid drive mode in which both the first and second clutches are engaged. The controller sets the second torque transfer capacity to a value that is more than zero and less than the target motor/generator torque of the motor/generator when switching from the electric drive mode to the hybrid drive mode and when starting the engine.

  • Patent number: 7586290
    Abstract: A state of charge of a battery (1) that drives a motor (6) is computed based on a discharge current measured by a current sensor (3) when the discharge current of the battery (1) does not exceed a rated discharge range of the battery (1). When the discharge current of the battery (1) exceeds the rated discharge range, the state of charge of the battery (1) is computed by estimating the discharge current of the battery (1) from a motor control signal, whereby current changes over a wide range can be found with good precision using the sensor (3), which has a narrow but high resolution measurable range, and the state of charge can be accurately detected.

  • Patent number: 7472769
    Abstract: A hybrid vehicle control system is configured to improve fuel economy by optimizing a torque transfer capacity of a clutch transmitting drive power from both an engine and a motor/generator while the motor torque provides at least part of the drive force. In particular, the system selectively controls a pair of clutches to switch between an electric drive mode and a hybrid drive mode. The torque transfer capacity of the clutch transmitting drive power from both the engine and the motor/generator to a drive wheel includes a motor/generator torque component and an engine torque component. The motor/generator torque component is determined based on a motor/generator torque and a torque transfer capacity margin allowance for the motor/generator torque. The engine torque component is determined based on an engine torque and a torque transfer capacity margin allowance for the engine torque when the drive wheel is driven at least by the motor/generator.

  • Publication number: 20070102208
    Abstract: A hybrid vehicle control system is configured to use automatic braking to compensate for an excess or deficiency of a braking force available from the power train of a hybrid vehicle that occurs when the hybrid vehicle switches from an electric drive (EV) mode to a hybrid drive (HEV) mode when the accelerator pedal depressing amount is detected as being substantially zero. In particular, hybrid vehicle control system determines whether a power train braking force from the power train is sufficient to achieve a target braking force. If the power train braking force is sufficient to achieve the target braking force when an accelerator pedal depressing amount is detected as being substantially zero, then a wheel brake is activated to apply a wheel braking force against a wheel of the vehicle to maintain the target braking force.
