Abstract:
An output power control apparatus for an internal combustion engine of a motor vehicle, comprising:an intake pipe for supplying intake air to an internal combustion engine mounted on a motor vehicle;a throttle valve installed in said intake pipe for regulating an amount of the intake air supplied to said engine;a throttle actuator for adjusting an opening degree of said throttle valve;a transmission for transmitting output power of said engine to a wheel system of said motor vehicle;shift information detecting means for detecting shift of said transmission to thereby generate shift information;an accelerator sensor for detecting an accelerator stroke of an accelerator pedal; andthrottle control means for setting a control quantity for said throttle actuator on the basis of at least said shift information and said accelerator pedal actuation quantity,wherein said throttle control means includes control quantity suppressing means for suppressing said control quantity, at least over a predetermined time period subsequent to a shift operation of said transmission, when said shift information indicates a shift operation of the transmission from a neutral range to a drive range, andwherein said control quantity suppressing means is operative to suppress an increase in the rate of said control quantity, such that it is equal to or lower than a predetermined value calculated over said predetermined time period subsequent to a shift operation of said transmission form said neutral range to said drive range.
