PROBLEM TO BE SOLVED: To obtain an engine output along with intention of a driver by reducing generation of torque shock upon acceleration and deceleration with an easy means. SOLUTION: A driver demand torque PTTRQB is set (S1) based on an acceleration opening, upper limit guard value KTRQGDD (constant value) for variationΔPTTRQB of the driver demand torque PTTRQB is set up (S2). The variationΔPTTRQB of the driver demand torque calculated from the difference between this time driver demand torque PTTRQB<SB>n</SB>and last time torque PTTRQB<SB>n-1</SB>and upper limit guard value KTRQGDD are compared (S3). WhenΔPTTRQB is larger than KTRQGDD, target demand torque PTTRQ is set up (S4) by adding the upper limit guard value KTRQGDD to the last time driver demand torque PTTRQB<SB>n-1</SB>. The target demand torque PTTRQ is restricted and a target throttle opening TANGLE is set up (S6) based on the target demand torque PTTRQ. COPYRIGHT: (C)2003,JPO
