PROBLEM TO BE SOLVED: To prevent driving vibrations which reduce durability of an actuator with generation of slight fluctuation in a target driving condition, while compensating response delay on control in a driving force source control device such as an internal combustion engine. SOLUTION: Fluctuation of time gradient of temporary target air intake pressure Pintx is determined beforehand (S214). The slight fluctuation of the time gradient due to calculation errors or detection errors is ignored (YES in S214). A variation state of target air intake pressure Pint is continued in the same gradient as before. Even though the gain is enlarged to make a throttle opening indication value at high response, the fluctuation due to the calculation errors or the detection errors is not reflected, which prevents repetition of forward/reverse directions of changing the throttle opening indication value. The driving vibrations are not generated in an electronic control type throttle valve. While compensating the response delay of the air intake pressure due to throttle opening control, the driving vibrations of the electronic control type throttle valve can be prevented, and the durability is not reduced even when the slight fluctuation is generated in the temporary target air intake pressure Pintx.
