We suggest the following solution of Friedman's equations: parameter of curvature K=0, scale factor R(t)=1 and non-null Cosmological Constant(CC). In this case Robertson-Walker's metric becomes Minkowskian. This special solution of Einstein's equation of General Relativity forces therefore us into renormalizing Einstein's Special Relativity (SR) with non-null CC. By introducing a maximal interval (Hyperbolic Horizon), we deduce the law of Hubble and transform in this way SR into HCR (Hyperbolic Cosmological Relativity). Euclidean Einstein's rigid ruler is replaced with Lobatchevskian LIGHT-distance. Both basic parameters of Cosmology, H (Hubble) and q (acceleration) are deduced on the only basis of Lorentz Transformation. Usual ad hoc Lemaitre's scale factor R(t) is replaced with Bondi's "scale factor k". We induce a global principle of equivalence between centrifugal (hyperbolic) acceleration and repulsive gravitation. Hidden density of dark energy is a relativistic effect of globally curved Minkowski's space-time (minimal acceleration). We obtain in this way an unexpected relationship between Einstein's CC (1917) and Poincare's gravitational pressure (1905) of vacuum.
