Abstract

The invention relates to an electric-controlled adjustable suspension system positioned based on a GPS and a control method, and belongs to the technical field of vehicle safety and comfort. An ECU receives carrier phase GPS position signals, is connected with a server network through wireless data communication, and transmits the position signals to the server network; the server network examines if control policies matched with the position signals exist; if so, the control policies are transmitted to the ECU, and it judges if a vehicle is kept to reach the preset time in the geographic position of a pavement with the type; if so, the ECU outputs control signals to a driver, and the driver controls a vibration reducer to work according to the control policies; and if not, the state switchover is not performed, the signals are not sent, and the vibration reducer keeps the previous working state. The system can use no or few sensors, so that the energy consumption is largely reduced.

Description

technical field [0001] The invention relates to an electronically controlled adjustable suspension system and a control method based on GPS positioning, and belongs to the technical field of automobile safety and comfort. Background technique [0002] Suspension devices are generally installed between the wheels and the body, which can be used to reduce the vibration and impact of the wheels on the body, improve the ride comfort of the wheels and protect the body and its cargo from damage. [0003] Traditional electronically controlled suspension devices include various sensors installed on the vehicle, and use the detected values ​​to adjust the damping force characteristics of the shock absorber, in this way to improve the ride comfort of the wheels. To put it simply, the sensors of the traditional suspension work in real time and consume a lot of power. [0004] The electronically controlled adjustable suspension system based on carrier phase GPS positioning reduces the ...
