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 an air suspension control system and method for bend previewing based on the Internet of Vehicles. The system comprises an ECU, a map data downloading module, a GPS positioning module, a vehicle speed sensor, a CAN bus and an executing mechanism, wherein the ECU comprises a serial port communication module, a CAN bus reading module, a bend discrimination module and an inflation and deflation position calculation module; when a vehicle runs, the curvature of the bend ahead is acquired and vehicle speed information is collected from the CAN bus by using the Internet of Vehicles, the pre-inflation position of an air spring and the pre-deflation position of the air spring are obtained through calculation, when the vehicle makes a turn, the air spring is pre-inflated and pre-deflated to inhibit lateral inclination of a vehicle body when the vehicle makes a turn, thereby improving the comfort and smoothness when the vehicle runs. The system has the advantages that compared with other air spring control systems, road information is acquired from the Internet of Vehicles, the system is rapid and convenient and has an ability to preview bends, collection informationis less, the cost is low, the installation is simple, and the system is suitable for the vehicle provided with the air spring to perform bend previewing on uncrossed roads.

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...
