PURPOSE:To improve responsiveness and controllability, by constituting so that, at the time of steady running, the opening of a throttle valve is controlled in response to the stepping-in amount of an accelerator and that, at the time of traction control, the opening is controlled by a control motor, and further that, at the time of constant speed running, the stroke control of a driving wire can be carried out. CONSTITUTION:An acceleration pedal 1 is connected to a throttle pulley 15 via an accelerator link 2 and a driving wire 4, and on one end of the output ends of this pulley 15, a throttle valve 16 is connected. In the course of the driving wire 4, an accelerator pulley 5 is interposed, and on one end of the pulley shaft of this pulley 5 a driving motor 7 is connected via a clutch 6. Further, in the course of the driving wire 4, an adjusting pulley 9 is interposed, and to the pulley shaft of this pulley 9 an adjusting rod 11 is connected. On the adjusting rod 11 a rack gear teeth 13 are formed, and with this rack gear 13 a pinion gear 13 provided on the output shaft of a control motor 12 is engaged. Further, on the respective pulley shafts of pulleys 5, 15, an accelerator opening sensor 8 and a throttle valve opening sensor 18 are provided.
