<P>PROBLEM TO BE SOLVED: To set a command value of proper clutch engaging hydraulic pressure to engine torque, without performing adaptation with respect to each combination of respective units. <P>SOLUTION: A time constant TCp of reflecting a hydraulic pressure response characteristic of a clutch C1 is calculated based on an actual state of the clutch C1 from a hydraulic pressure response model, and since a torque calculating time constant TCe used in an engine torque response model for calculating pre-reading engine torque T<SB POS="POST">E</SB>mod of reflecting the hydraulic pressure response characteristic of the clutch C1 is calculated based on the time constant TCp. the time constant TCp only has to be calculated by presetting the hydraulic pressure response model with respect to each automatic transmission unit. The torque calculating time constant TCe only has to be calculated based on the time constant TCp by presetting a pre-reading torque calculating time constant map with respect to each engine unit. Thus, command hydraulic pressure S<SB POS="POST">PCI</SB>of the clutch C1 is properly calculated based on the properly calculated pre-reading engine torque T<SB POS="POST">E</SB>mod without performing the adaptation with respect to each combination of the respective units. <P>COPYRIGHT: (C)2012,JPO&INPIT |
