Abstract

The invention discloses a multi-mode damping control system based on Internet of Vehicles for a vehicle suspension system. The system is composed of a GPS positioning module, a map data download module, an ECU, a damping control mode switching module, and an actuating mechanism, wherein the ECU is composed of a serial port communication module, an information processing module, a calculation module, and a road working condition discrimination module which are in series connection in sequence; and a current position and vehicle speed is obtained by utilizing a GPS, coefficients of road unevenness and road curvature in map data are obtained by utilizing the Internet of Vehicles, road conditions ahead are judged according to the obtained road information, the judgment time is short, responseis rapid, so that a damping control strategy most suitable for vehicles to be used in road conditions ahead is selected, and modes are switched quickly, so that the vehicles have the preview capability of coping with road changes, and smoothness and handling stability during a driving process are improved.

Description

technical field [0001] The invention relates to the field of vehicle control, in particular to a damping control system of a vehicle suspension system. Background technique [0002] Vehicles will be subjected to vibrations from the road surface and their own vibration sources during driving, such as braking and acceleration will cause nodding and pitching vibrations, and steering will cause rolling vibrations. Suspension damping is a key component in the vehicle suspension system, which plays a role in attenuating vibration, dissipating energy from the outside world, and transmitting the damping force to the vehicle body, which is extremely important for the selection of its control strategy. In order to improve the ride comfort and handling stability of the car, many damping control strategies should be adopted, among which, the ceiling damping control, the ground roof damping control and the sky-ground roof hybrid control are due to their better control effect, simple stru...
