Shift control apparatus for an automatic transmission and shift control method for an automatic transmission |
摘要 |
A control apparatus effects shift control of an automatic transmission to produce gear stage shifting using a first shift pattern in which gear stage shifting is based on vehicle speed and throttle opening and a second shift pattern in which gear stage shifting is based on the vehicle speed and a road condition, with gear stage shifting being based on the second shift pattern under vehicle deceleration. The gear stage shift is based on the second shift pattern without shifting from a first gear stage to a second gear stage, which is a higher-speed gear stage than the first gear stage, when the vehicle driving condition changes from a condition crossing a shift line which commands a shift from the first to the second gear stage on the first shift pattern to a condition switching from the first shift pattern to the second shift pattern according to a prescribed condition.
