PURPOSE:To prevent a car from reckless driving caused by some reason by setting the upper-limit value of a target throttle opening at the connected state of a power transmission mechanism lower than the upper limit value at the disconnected state. CONSTITUTION:At an idling state, a CPU successively obtains a target number of idling revolutions NSET in accordance with a temperature of cooling water and a load of a cooler, a temporary target throttle opening T1 corresponding to the above, a correction term T2=k(NSET-N) from an actual number of revolutions N and a constant k, and then a target throttle opening TSET on the addition of a past correction term T2 under the limit of an upper-limit value. Meanwhile, in an N-range, when TSET is greater than the upper limit value TN of the N-range, TSET=TN is selected, and when smaller, TSET is kept as it is. When TSET is greater than the upper-limit value TD in a D-range, TSET= TD is selected, and when smaller, TSET is kept as it is. Since these upper-limit values are set as TN=9 deg. and TD=7 deg., a car is prevented from a problem of reckless driving. |
