Title:
SUSPENSION SYSTEM AND CONTROL METHOD THEREOF, AND VEHICLE
Document Type and Number:
WIPO Patent Application WO/2023/065304
Kind Code:
A1
Abstract:
A suspension system. The suspension system comprises suspension assemblies (1), drivers (2), a controller (3), a compressor (4), and a gas tank (5). Each suspension assembly (1) is provided with a gas spring (101) and a height sensor (103), gas is contained in the gas tank (5), the gas tank (5) is connected to the compressor by means of a first vent pipeline (6), and the compressor (4) is connected to the gas spring (101) by means of a second vent pipeline (8). The first vent pipeline (6) is provided with a first switch valve (7), and the second vent pipeline (8) is provided with a second switch valve (9). Each driver (2) is separately electrically connected to the controller (3), the compressor (4), the first switch valve (7), the second switch valve (9), and the height sensor (103). The suspension system can be mounted between wheels (200) of the vehicle and a vehicle body (100), so that in the working process of the suspension system, the height between the wheels and the vehicle body is adjusted according to the working condition and the external input of the vehicle, and the stability and comfort of the vehicle are improved. Each part of the structure of the suspension system is of an independent structure, so that unified control of the whole vehicle is achieved. Also disclosed are a suspension system and a vehicle.
