<p>PURPOSE:To enable to perform stepless gear-shifting control along an ideal operating curve, by conrrolling the gear-shifting ratio of the transmission in the headline as a function consisting of the actual performance of a power transmitting system and a desired system performance assigned by an instruction device and controlling the amount of fuel supply according to the desired system performance. CONSTITUTION:Rotation of an engine 10 is transmitted to a CVT (continuously variable transmission) 14 through a clutch and the like, and the properly gear- shifted rotation is transmitted to an output shaft 16. In such device, the ratio of the CVT14 is set by a CVT ratio controller 17. The controller 17 generates a ratio changing rate signal kR as a function consisting of an output T0 measured by a torque sensor 19 and a horse power or a torque alpha instructed by an accel pedal 18. Meanwhile, the engine 10 regulates and controls a fuel feeder 12 through an engine control circuit 100 according to an engine rotational speed measurement Ne. Additionally, in case of the instruction torque alpha by the pedal 18 being reduced, the fuel flow to the fuel feeder 12 is decreased.</p> |
