  • Publication number: 20070102207
    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: 5959572
    Abstract: A preceding-vehicle follow-up control apparatus is arranged to calculate a target vehicle speed for following-up a preceding vehicle at a target vehicle-to-vehicle distance. The target vehicle speed is calculated from an equation having a form of a linear combination of a form which includes a linear connection between a product of a first gain and a difference between the vehicle-to-vehicle distance and the target vehicle-to-vehicle distance and a product of a second gain and the relative speed. The control apparatus controls a driving apparatus and a transmission apparatus of a vehicle so as to adjust a vehicle speed at the target vehicle speed. This enables the vehicle-to-vehicle distance to be converged into a target value without excessively increasing or decreasing the relative speed during this follow-up control.
