Abstract:
A cooperative control apparatus for controlling an automotive vehicle, so as to effect a cooperative control of an automatic transmission and a drive power source which produces an output to drive the vehicle through said automatic transmission, said automatic transmission incorporating a frictional coupling device which is engaged to place said automatic transmission in a power transmitting state, during power driving of the vehicle with the output of said drive power source, and is released to place said automatic transmission in a power disconnecting state, during coasting of the vehicle, said cooperative control apparatus comprising:control initiating condition determining means for determining whether a control initiating condition required to initiate an output increase control for temporarily increasing said output of said drive power source is satisfied or not, depending upon whether an operation to accelerate the vehicle is performed during said coasting of the vehicle while said frictional coupling device is placed in a released state; and output increase control means operable when said control initiating condition determining means determines that said control initiating condition is satisfied, for effecting said output increase control such that said output of said drive power is larger by a predetermined amount than when said output increase control is not effected, so that said output increase control by said output increase control means reduces a time required for said frictional coupling device to be engaged to place said automatic transmission in said power transmitting state for accelerating the vehicle.
