We propose the Kaluza–Klein inspired Brans–Dicke gravity model containing possible existence of dark matter and dark energy. The massive scalar field coupled with gravity in 5 dimensional space–time can be reduced to 4 dimensional gravity along with the dilaton $\varphi$, gauge fields $A_{\mu }$, and the tower of scalar fields ${\eta }_n$. Two additional gauge fields are introduced to form “Cosmic Triad” vector field scenario. We then use the dynamical system approach to analyse the critical points and their corresponding physical parameters. We found that in the case where only the zero mode of the Kaluza–Klein scalar is decoupled, the system contains both dark matter and dark energy phase depending on the mass parameter with the presence of the gauge field.

我们提出了Kaluza-Klein启发的Brans-Dicke重力模型，该模型包含暗物质和暗能量的可能存在。大规模标量场与重力在5维时空中的结合，可以随着引力子减少到4维重力$\varphi$，规格字段 ${\mathrm{一种}}_{\mu }$和标量场塔 ${\eta }_{ñ}$。引入了两个额外的量规场以形成“宇宙三合会”矢量场场景。然后，我们使用动力学系统方法来分析临界点及其相应的物理参数。我们发现，在仅解开Kaluza–Klein标量的零模的情况下，系统会根据质量参数的存在（包含标尺场）同时包含暗物质和暗能量相。
