Embodiment 1

[0036] According to an embodiment of the present invention, an embodiment of a system for controlling an airbag is provided, wherein, figure 1 is a schematic diagram of the system structure of the airbag control system according to an embodiment of the present invention, such as figure 1 As shown, the system includes: electronically controlled air suspension system and electrical box.

[0037] Optionally, the electronically controlled air suspension system is mainly composed of electronic control unit (ECU), solenoid valve, height sensor, air bag and other components. During the working process of the electronically controlled air suspension system, the height sensor detects the distance between the frame and the axle to determine the change of the vehicle height, and transmits the detected vehicle height to the electronic control unit, and the electronic control unit also receives the vehicle height. other input information of the vehicle, such as vehicle brake information, ...

Embodiment 2

[0060] According to an embodiment of the present invention, an embodiment of a method for controlling an airbag is also provided. It should be noted that the steps shown in the flow charts of the drawings can be executed in a computer system such as a set of computer-executable instructions, and, Although a logical order is shown in the flowcharts, in some cases the steps shown or described may be performed in an order different from that shown or described herein.

[0061] It should be noted that the airbag control method provided in this embodiment is applied to a vehicle, and the vehicle includes at least an electronically controlled air suspension system and an electrical box, and the electronically controlled air suspension system is connected to the mains through the electrical box. Wherein, the structure of the electrical box has been described in Embodiment 1, and will not be repeated here.

Abstract

The invention discloses a system, a vehicle, a method and a device for controlling an air bag. The system comprises an electronic control air suspension system which at least comprises an air bag of an air suspension; an electric appliance box which is connected with the electronic control air suspension system and provided with a mains supply interface, a plurality of electromagnetic valves are arranged in the electric appliance box, and deflation and inflation of the air bag are controlled by adjusting opening and closing of the electromagnetic valves. The technical problem that an existing electronic control air suspension system cannot control inflation and deflation of an air bag when a vehicle is not provided with an energy storage battery is solved.

Description

technical field [0001] The invention relates to the field of vehicle control, in particular to a system, vehicle, method and device for controlling an airbag. Background technique [0002] When the vehicle is running, when the load and the road surface change, the stiffness of the vehicle's air suspension also changes. Among them, the air suspension is composed of a compressor, an air storage tank, a height control valve, an air bag, a control rod, etc. The height control valve controls the inflation and deflation of the air bag, thereby changing the suspension stiffness and improving the ride comfort of the vehicle. [0003] The traditional air suspension control mode uses a mechanical height valve, that is, the inflation and deflation of the airbag is adjusted through the opening of the height control valve, so as to maintain a constant driving height of the vehicle. [0004] With the development of vehicle control technology, the electronic control method gradually repla...
