Abstract

PURPOSE: To control engine behavior into a settled deirable condition in proportion to running load of the vehicle by controlling speed ratio of a stageless speed change gear taking engine behavior, vehicle running load and vehicle property, engine property as signals.
CONSTITUTION: A physical gain detecting part Y detects engine rotation, output axle rotation, air blast force, brake, accelerator, hilly road, and weight, which input is given to input ports 308, 309 in the control circuit X. These signals given input are transmitted to a CPU 302 together with speed ratio control program memorized into a ROM 307 and physical gain convertion table from measurement values from each sensor, computation is done. Output controls through outport ports 310, 311 an actuator AC to control a swash plate of an oil-pressure pump motor M1 and a solenoid valve 120 to control a clutch.
