Embodiment Construction

[0028] The present invention will be described in further detail below through specific embodiments.

[0029] Such as figure 1 as shown, figure 1 Preview the structure diagram of the air suspension control system for the curve. The system is composed of ECU, map data download module, GPS positioning module, vehicle speed sensor, CAN bus and actuator. The ECU includes a serial port communication module, a CAN bus reading module, a curve discrimination module and an inflation and deflation position calculation module.

[0030] The vehicle speed sensor is used to collect the vehicle speed information v of the vehicle, and send the collected vehicle speed information v to the CAN bus.

[0031] The GPS positioning module is used to obtain vehicle location information in real time, and send the obtained location information to the ECU.

[0032] The map data download module is used to receive the vehicle location information and download the map data of the current vehicle locati...

Abstract

The invention relates to a curve preview air suspension control system and method based on Internet of Vehicles, comprising an ECU, a map data download module, a GPS positioning module, a vehicle speed sensor, a CAN bus and an actuator. The ECU includes a serial port communication module, a CAN bus reading module, a curve discrimination module and an inflation and deflation position calculation module. When the vehicle is driving, use the Internet of Vehicles to obtain the curvature of the curve ahead and collect the vehicle speed information from the CAN line, and obtain the air spring pre-inflation position and air spring pre-deflation position through calculation. Deflate to suppress body roll when the vehicle is cornering, and improve the comfort and smoothness of the vehicle when driving in curves. Compared with other air spring control systems, this system obtains road information from the Internet of Vehicles, which is fast and convenient, has the ability to preview curves, and collects less information, has low cost, and is easy to install. It is suitable for vehicles equipped with air springs. Curve preview on roads without intersections.

Description

technical field [0001] The invention relates to an air suspension control system, in particular to a curve preview air suspension control system based on Internet of Vehicles. Background technique [0002] When the vehicle is running on a curve, it will produce body roll, and the roll of the body will affect the comfort of the driver and passengers when the vehicle is cornering and the ride comfort of the vehicle. In severe cases, it will cause rollover and serious accidents. traffic accident. Therefore, it is necessary to adjust the vehicle body posture to suppress the roll angle and improve the ride comfort and comfort of the vehicle when the vehicle produces a large roll angle. The air spring has ideal stiffness characteristics and the characteristics of adjustable spring height. It can adjust the body posture by charging and deflated to change the specific spring height. Therefore, the air suspension has a wide range of applications in the body posture adjustment. Duri...
