TRANSMISSION CONTROL DEVICE OF A STEPLESS TRANSMISSION CHANGING THE ROTATION DRIVING FORCE OF AN ENGINE WITHOUT STEPS

摘要

PURPOSE: A transmission control device is provided to reduce the change of a target transmission ratio by setting the target transmission ratio by using pseudo accelerator openness.;CONSTITUTION: A target transmission ratio setting unit (203) sets a target transmission ratio and actual accelerator openness. A transmission control unit (204) controls the transmission of a stepless transmission for the target transmission ratio. A determining unit (205) determines whether a vehicle is driven on an uphill road. A pseudo accelerator openness generating unit (206) generates pseudo accelerator openness bigger than actual accelerator openness to input the pseudo accelerator openness into the target transmission ratio setting unit. The target transmission ratio setting unit sets the target transmission ratio by using the pseudo accelerator openness.;COPYRIGHT KIPO 2013;[Reference numerals] (201) Acceleration intension-determining unit; (202) Transmission mode setting unit; (203) Target transmission ratio setting unit; (204) Transmission control unit; (205) Uphill road-driving determining unit; (206) Pseudo accelerator openness generating unit; (207) Memory unit; (23) Accelerator control amount sensor; (24) G sensor; (27) Rotation rate of a secondary pulley-sensing sensor; (30) Oil pressure-controlling unit
