For the electronically controlled active hydraulic suspension, it is slightly inferior to the electronically controlled active air suspension dao in terms of comfort, because it is still built on the basis of the traditional suspension zhuan, but it is only the height of the body and the shock absorber. Damping is adjusted. Its high-frequency shock absorption ability is worse than that of air suspension. Electronically controlled active hydraulic suspension is also more difficult to respond to complex road conditions, and it may even cause excessive oil pressure to affect life. Electronically controlled active hydraulic suspension is relatively simple in structure , The front Macpherson and rear trailing arm structures can be competent; the suspension structure required by the electronically controlled active air suspension is more complicated, because the air spring is installed independently and connected to the upper and lower control arms of the suspension, so we often match it In the suspension structure of the front double wishbone and the rear multi-link. So in general, the air suspension is much better than the hydraulic suspension, but the structure is more complicated than the hydraulic suspension, and the maintenance is not as convenient as the hydraulic suspension.
