However, as the vibration damper of the important component of the suspension, the kinematic viscosity of the hydraulic oil changes along with the temperature change, so that the damping force of the vibration damper changes, and the perception evaluation of the whole vehicle is affected. Meanwhile, if the temperature of the hydraulic oil of the shock absorber is too high, phenomena such as oxidization, aging and deterioration are easy to occur, and the normal operation of the shock absorber is affected.
