We explore the impact of the chameleon mechanism in scalar field Einstein–Gauss–Bonnet gravity on the dynamics of cosmological parameters. Conducting a thorough analysis of the phase space, we identify conditions under which the future attractor does not depict a singular universe. Our conclusion is that although Einstein–Gauss–Bonnet scalar field gravity offers an inflationary solution as a future attractor, it is unable to account for the late-time acceleration of the universe and it can not describe a universe similar to that provide by the \(\Lambda \)CDM model. On the other hand, when the matter source is described by a massless scalar field, then the de Sitter universe is a future attractor. However, the hyperbolic inflationary solution provided by the two scalar fields does not exist.

我们探讨了标量场爱因斯坦-高斯-邦内引力中的变色龙机制对宇宙学参数动力学的影响。通过对相空间进行彻底分析，我们确定了未来吸引子不描绘奇异宇宙的条件。我们的结论是，尽管爱因斯坦-高斯-邦内标量场引力提供了作为未来吸引子的暴胀解，但它无法解释宇宙的后期加速，并且无法描述类似于“宇宙”所提供的宇宙。 (\Lambda \)CDM 模型。另一方面，当物质源由无质量标量场描述时，德西特宇宙就是未来的吸引子。然而，两个标量场提供的双曲暴胀解并不存在。
