摘要： The present invention provides a line pressure control device for a continuous transmission in an automotive vehicle, wherein a life of a belt is capable of being lengthened by avoiding a slip of the belt under any running conditions. The line pressure control device comprises a pressure control valve for generating a line oil pressure of an oil pressure line by controlling an output oil pressure of an oil pressure pump, the continuous transmission for changing a rotating speed of an internal combustion engine manipulated by the line oil pressure, a controlling process of a required line oil pressure for conveying an input torque of the continuous transmission from a throttle opening signal of the internal combustion engine, and an input and an output shaft rotating speeds of the continuous transmission, a memorizing process of the characteristics data of an output oil pressure for the oil pressure pump, a process of computing a possible output line oil pressure of the oil pressure pump from the characteristic data of the output oil pressure and the input shaft rotating speed and comparing the required line oil pressure with the possible output line oil pressure, and a control means for controlling a rotating speed and an output torque of the internal combustion engine, wherein the required line oil pressure is kept within the possible output line oil pressure.
