摘要： A vehicle control system capable of reducing change in acceleration of the vehicle before and after the termination of fuel-cut control.Before the termination of the fuel-cut control, the vehicle control system reduces a pumping loss by increasing an air intake and a load torque of an auxiliary device thereby preventing the vehicle to be decelerated excessively, and after the termination of the fuel-cut control, the vehicle control system increases the load torque of the auxiliary device thereby preventing the vehicle to be accelerated abruptly. Therefore, the vehicle speed will not be lowered unnecessarily before the termination of the fuel-cut control so that an execution time of the fuel-cut control can be extended. Moreover, driving comfort can be improved by thus reducing a change in acceleration.

摘要： A continuously variable transmission is mounted on a vehicle capable of selecting plural drive modes and changes a target engine speed between drive modes. A pulley ratio is controlled by a motor. An ECU for transmission control includes a calculation section which outputs a target engine speed as a function of throttle opening and vehicle speed, and a motor control value determination section which outputs a control value for controlling the motor based on the target engine speed and an actual engine speed. In a case where, when a drive mode is selected, the current target engine speed changes by an amount exceeding a predetermined judgment value according to vehicle speed, the motor control value determination section updates the current target engine speed in a stepwise manner. The resulting configuration reduces a shift shock caused by a drive mode change.

摘要： A controlling system for a vehicle with a continuously variable transmission, which can render a sufficient accelerating feeling in responsive to a driver's requirement. A controller, upon judgment of an acceleration requirement, sets a target drive force higher than the target drive force upon normal calculation upon normal operation of an accelerator pedal, and sets a target rotation speed for acceleration higher than the target rotation speed upon the normal operation and increasing with an increase of the vehicle speed by a predetermined gradient. The speed change ratio of the continuously variable transmission and the output torque of the engine are controlled such that the set target drive force is achieved, and an input shaft rotation speed of the continuously variable transmission coincides with the target rotation speed for the set acceleration. Thus, upon acceleration requirement by the driver, the target drive force increases and the output rotation speed of the drive source increases so that the sufficiently high accelerating feeling from the vehicle can be obtained.
