Abstract: <P>PROBLEM TO BE SOLVED: To make an occupant not feel a sense of discomfort caused by the variation of the number of revolutions of an engine.  <P>SOLUTION: This control device determines whether a vehicle is in a coast state or not (S1), and when the coast state is determined, the control device determines whether the vehicle is in a lockup state or not (S2). When it is determined that the vehicle is not in the lockup state, the control device determines whether there is a power generation request or not (S3). When there is the request, the control device operates the charging state of a battery. Next, it is determined whether the number of revolutions of the engine is the number of idle revolutions or not (S4), and when it is not the number of idle revolutions, it is determined whether the engine is cut in fuel supply or not (S5). When the fuel cut is conducted based on the determination, and when a prescribed time has elapsed (S7), a difference between the number of revolutions of the engine after the cut of the fuel and the number of revolutions the engine after the lapse of the prescribed time is operated (S8). A road gradient is estimated according to the difference (S9), the target number of revolutions is set by the estimated road gradient (S10), and torque that corresponds to a generation amount is operated by the target number of revolutions, thus suppressing the variation of the number of revolutions.  <P>COPYRIGHT: (C)2005,JPO&NCIPI

Filed: 2003-05-08
Abstract: <P>PROBLEM TO BE SOLVED: To accurately detect the time of slippage termination of a belt with respect to a control device for optimizing clamping force for setting torque capacity of a continuously variable transmission by detecting slipping.  <P>SOLUTION: In the control device of a continuously variable transmission, an estimated change gear ratio is obtained on the basis of a past change gear ratio. Based on the estimated change gear ratio, slipping termination is detected. The control device is provided with a gear change command value limiting means (step S103) for limiting a change of a gear change command value when occurrence of slipping is judged. When the slipping judgment is made, a change of the gear change command value is limited to fix the value at the point of time when the judgment is made. By so doing, fluctuation of the change gear ratio caused by a change of the gear change command value is prevented, which improves accuracy of prior estimation of a gear change ratio based on a gear change ratio. As a result, accuracy of the slipping termination judgement based upon comparison between the estimated change gear ratio and the actual change gear ratio is improved.  <P>COPYRIGHT: (C)2005,JPO&NCIPI
