Control device for continuously variable transmission and control method thereof

摘要

When a shift lever is shifted from an N range to a D range and a predetermined learning condition is established, a learning timer tm_pulse up to a point at which a pulse signal is detected by a primary pulley rotation speed sensor is calculated, and when a deviation between the learning timer tm_pulse and a reference correction amount ”P_offset is larger than a predetermined threshold ”t_pulse_dif, a learned correction amount P_offset is updated.
