According to the latest patent, apple car may be equipped with intelligent active suspension system to improve the ride comfort of drivers and passengers. Suspension system is one of the standard configuration of the vehicle, mainly to reduce the impact of road turbulence on the driving experience, so as to achieve smooth driving. The active suspension system has the function of controlling body vibration and body height. It can adjust dynamically according to the road conditions, so that the suspension system is always in the best vibration reduction state. < / P > < p > at present, the mainstream active suspension system mainly adopts hydraulic form, which is controlled by on-board computer to quickly add and remove fluid from all parts of suspension, so as to ensure the stability of driving. The amount of fluid can also be adjusted at any time to change the softness or strength of the suspension according to the driver’s needs. < p > < p > according to the patent list released by the U.S. trademark and patent office on Tuesday, Apple has obtained a patent entitled “active suspension system with energy storage device”, which describes an improved scheme based on the existing hydraulic suspension system. < / P > < p > effectively at its core is a hydraulic actuator, which is connected to the chassis and hub, and to the hub to the chassis via another linkage, with the upper and lower chambers filled with liquid and connected to the actuation and suspension systems, controlled by hoses at both ends. By adding or removing the liquid stored in the upper and lower cavities, the effective length of the piston assembly can be changed, thus increasing and reducing the height of the chassis from the wheel. < / P > < p > Apple has added an additional element to its relatively simple design: a separate “energy storage device.”. It consists of a cylinder with connections at the top and bottom, which are inserted into the same hose as the hydraulic actuator and move the hydraulic fluid freely between itself and the piston chamber. < / P > < p > the energy storage device has a central element which can be effectively divided into two parts, adding two chambers in a similar way to the main actuator. The central element is not fixed in place and can move along the length of the container, which largely depends on the amount of liquid in each chamber. < / P > < p > the key is that the central element is compressible, that is, it exerts an outward force on the two chamber areas, but can be pushed back by the hydraulic oil. The central element can be pushed outwards using a spring, although it can also contain gas, which can be pumped in and out again to change the amount of compression. < / P > < p > such a system can also reduce the amount of hydraulic fluid required for operation and even better control of ride smoothness, especially in the gas based compressible section. Under unfavourable driving conditions, the piston in the actuator is forced to move on the system, which may also reduce vibration. After 12 years, “world class Super project” Shantou Bay Tunnel ushers in a historic breakthrough today
