Abstract:
A shift control system and a shift control method configured to execute a skip shift smoothly are provided. The shift control system selects an interim gear stage with reference to a control map. The control map is configured to determine: an intense region where a driver is allowed to sense an increase in the acceleration sufficiently based on an unconscious period, and a stimulation intensity; and a moderate region where acceleration is increased in a mild manner. During execution of the skip shift, the acceleration is increased in a mild manner by shifting the gear stage from an initial stage to the interim gear stage, and then increased significantly by shifting the gear stage from the interim gear stage to a target gear stage.
