A drive axle assembly for an all-wheel drive vehicle includes an adaptively controlled first hydraulic coupling for providing front-to-rear torque transfer control to a first wheel and an adaptively controlled second hydraulic coupling for providing front-to-rear torque control to a second wheel. The illuminable tank enables a user to determine the level of liquid in the tank, to make the tank more visible at night, and to light the area surrounding the tank’s mouth and a spout. The method may also include receiving a scaling input from a user. In addition, the privileged service can measure the hypervisor at runtime in an attempt to detect evidence of tampering with the hypervisor. Therefore, it can be prevented that the control parameter of the damping force is varied largely or varied in a short period by the influence of noise, and the driving stability control of the vehicle can be executed exactly and the noise caused by switching the damping force of the damper can be reduced.
