Abstract

PURPOSE:To enhance the durability of a belt and its transmitting efficiency by correcting the line pressure to optimum value in response to changing coefficient of friction because of oil temp. CONSTITUTION:Degree of opening of a throttle and signals from revolving speed sensors 73, 74 are fed into an engine torque computing part 81, to determine the engine torque T. The output of a virtual gear ratio computing part 75 is fed into a requisite line pressure setting part 82 to determine the requisite line pressure PLU per unit torque, and the obtained value is together with engine torque T fed into a target line pressure computing part 83. This output PL is fed into a duty ratio setting part 84, followed by correction with a signal given by an oil temp. sensor 86, to control a solenoid valve 65 through a drive part 85. Thus the line pressure can be controlled to optimum value in response to changing coefficient of friction because of oil temp., which should lead to enhancement of the durability of belt and its transmitting efficiency.
