摘要:
A control apparatus and method for a vehicle including a stepped automatic transmission and a shift control device which controls an operation of the automatic transmission based on a vehicle state such as a value corresponding to a driving force required for the vehicle, according to a pre-stored shift pattern having a shift line for determining whether shifting is performed from one shift speed to an adjacent shift speed. In the control apparatus and control method, one shift pattern is automatically selected, based on the vehicle state, from among multiple shift patterns including at least a first shift pattern in which the shift line is set such that the driving force for the vehicle, that is decided by a gear ratio of the shift speed and engine output characteristics, continuously and smoothly changes when shifting is performed from one shift speed to an adjacent shift speed, and a second shift pattern in which the shift line is set such that the use of a region, where an engine rotational speed for obtaining the driving force for the vehicle becomes a predetermined high rotational speed, is avoided.
