The generalized kinetic term of a dilaton gives the classical superinflation without recourse to any potential, and the quantum version of the dilaton gravity exhibits the finite curvature and graceful exit. For p=2 case, the model corresponds to the RST quantization of the s-wave sector of the four-dimensional Einstein cosmology. Further, the de Sitter universe is realized for p=8 and the smooth transition to the Minkowski space-time is possible. Even in the accelerating contraction case of the universe for -4<p<0, the curvature singularity does not appear in a certain branch.
