PURPOSE:To perform suitable control of a slip even in a case of a vehicle having an air-fuel ratio control device by correcting a slip amount according to a prestored relation based on an air-fuel ratio feedback correction signal when a slip amount of a direct coupling clutch is controlled to a target value. CONSTITUTION:The power of an engine 10 is transmitted to drive wheels through a torque converter 12 having a direct coupling clutch 32 and a stepped type automatic transmission 14. An oil pressure control circuit 44 for shift control and an oil pressure control circuit 46 for controlling engagement of the direct coupling clutch 32 are respectively connected to the automatic transmission 14. Further, the two oil pressure control circuits 44 and 46 are respectively controlled by a slip control device 42. Meanwhile, an air-fuel ratio control device 100 controls a slip control device 42 as well as a fuel injection valve 112. In this case, a slip amount of the direct coupling clutch 32 is regulated to a target value by a slip control device 42. The slip amount is corrected according to a prestored relation and based on an air-fuel feedback correction signal. |
