PURPOSE:To make it possible to obtain a satisfactory accelerating feeling upon acceleration in the condition of optimum fuel consumption, by controlling a throttle valve to change the load of an engine in addition to the control of gear ratio of a stepless speed change mechanism. CONSTITUTION:There are provided a gear ratio regulating section A for changing the gear ratio of a stepless speed chang...

PURPOSE:To always ensure an optimum line pressure to enhance the responsiveness of a stepless speed change unit, by regulating the line pressure fed to actuators for changing the gear ratio of the speed change unit in accordance with the amount of intake-air in an engine intake-air system, which substantially corresponds to the torque of an engine. CONSTITUTION:In a stepless speed change unit in w...

PURPOSE:To prevent a belt from being exerted with large shocks upon abrupt deceleration to enhance the durability of the V-belt, by compensating a reference line pressure determined in accordance with the operating condition of an engine, to a low value upon detection of abrupt deceleration. CONSTITUTION:In a stepless speed change unit 4 in which the gear ratio is changed by adjusting the groove g...

PURPOSE:To maintain the line pressure at a suitable value in accordance with the torque of an engine, by setting the line pressure in accordance with the amount of fuel injection which is detected by a fuel injection amount detecting means, in order to regulate the line pressure for hydraulic actuators for changing the gear ratio of a stepless speed change unit. CONSTITUTION:In a stepless speed ch...

PURPOSE:To make it possible to attain the shift of operation of a stepless speed change unit into a desired acceleration in a short time, by controlling a gear ratio regulating section such that the greater the absolute value of difference between an actual vehicle acceleration and a desired acceleration, the greater the change rate of gear ratio of a stepless speed change mechanism becomes. CONST...

PURPOSE:To make it possible to give a satisfactory feeling of acceleration to the driver, by controlling such that a predetermined acceleration is maintained until an upper vehicle speed limit or an upper engine rotational speed limit, which are determined in accordance with the operating condition of an accelerator regulating means, is reached. CONSTITUTION:In an arrangement in which the gear rat...

PURPOSE:To make it possible to give a satisfactory feeling of acceleration to the driver, by controlling a gear ratio regulating section in accordance with a desired vehicle acceleration which is set in accordance with the difference between a desired vehicle speed and an actual vehicle speed or the difference between a reference operating amount of an accelerator regulating section and an actual ...
