<p><P>PROBLEM TO BE SOLVED: To prevent generation of malfunction of a start clutch due to creep control. <P>SOLUTION: Even when general creep control start conditions are satisfied (S10-30), with negative acceleration of a vehicle (S40), creep control is not executed (S50). In a case of transfer from cost control to creep control (S90), engagement pressure Pclt at a forward motion clutch 38 is gradually increased at a prescribed pressure increasing gradient (S100). In a case of transfer from neutral control to the creep control (S120), engagement pressure at the forward motion clutch 38 is immediately increased to engagement pressure Pcltcrip for creep control (S140). In a case of transfer from start control to creep control (S130), engagement pressure Pclt at the forward motion clutch 38 is immediately deducted from the engagement pressure Pcltcrp for creep control (S140). In addition, the engagement pressure Pcltcrp for creep control is changeably set to be smaller as speed ratioβat the forward motion clutch 38 is higher (S80). <P>COPYRIGHT: (C)2004,JPO</p> |
