Cool! The world's first programmable air suspension!
In 221 BC, Chinese Qin Dynasty craftsmen installed a device called "Futu" between the chassis and axle of a carriage to reduce vibration from the ground, and the world's first vehicle shock absorption system was born.
Beginning in the 16th century, Europeans began to think about a more comfortable shock absorption system. They hung the carriage on the four pillars of the carriage chassis with belts, and then gave this system a name-suspension. In 1776, the leaf spring used in the carriage was patented, so the damping system using metal springs was used until the 20th century.
In 1920, Frenchman George Messier designed the first real air spring and conducted a real vehicle test. Then in 1929, the Czechoslovakian TATRA Motor Company also tried the design of air springs and equipped the rear axle of the T24 truck with air springs.
In 1957, Cadillac Eldorado Brougham achieved mass production of air suspension models for the first time. Although the response speed of the sensors did not reach the desired effect, it did not prevent Cadillac from becoming a milestone in the history of suspension development.
In 1993, the Electronically Controlled Air Suspension (ECAS) developed by Dunlop System Components in the United Kingdom was used in Land Rover Range Rover. The system can provide 5 fixed suspension heights to cope with different off-road conditions, and the body height will automatically change according to the vehicle speed. . Since then, Land Rover Range Rover has become a symbol of upgrading from traditional air suspension to electronically controlled air suspension.
In 2020, China Shenzhen Deping Guohan Automotive Electronic Technology Co., Ltd. launched the world's first programmable electronically controlled air suspension system-DOWN second-generation LCD Bluetooth five-segment version. For the first time, the suspension system is controlled through a mobile phone APP, and the vehicle's Suspension technology has entered the mobile era.
The DOWN second-generation LCD Bluetooth five-segment version can set 5 groups of different height data for 4 air springs. Different from the Range Rover, the height of the 5 groups of the Range Rover is fixed and synchronized with the 4 air springs, while the 5 groups of DOWN data can be set freely, and the height of the 4 air springs can also be determined at will. This makes the car's posture programmable, and many magical actions that Land Rover Range Rover cannot do can be realized. Moreover, the DOWN system can be directly connected to the mobile phone APP to display the air pressure of the four airbags and the air storage tank in real time, so that the owner can see the state of his suspension at a glance.
