  • Patent number: 8190340
    Abstract: In a shift control device for an automatic transmission according to this invention, when the engine load increases such that a shift to a first gear position on a low speed side of a current gear position is required, control is performed to calculate an estimated vehicle speed following the elapse of a time required to shift to the first gear position and set a second gear position from the estimated vehicle speed and the engine load on the basis of the shift map.
