Abstract

The invention provides an air suspension height adjusting method and system, and the method comprises the steps: adjusting air springs of a front axle and a rear axle to target heights according to a driving mode selected by a driver; when the adjusting height of the air springs exceeds a preset value, the air springs of the front axle and the rear axle are sequentially adjusted in a graded mode; and when the vehicle is not in the driving mode switching state and the vehicle judges that the height of at least one air spring does not meet the set tolerance zone requirement through self-inspection, self-adaptive independent height adjustment is conducted on the corresponding air spring. By means of the scheme, self-adaptive adjustment and graded adjustment of the air springs can be achieved, accumulated errors caused by simultaneous adjustment are eliminated, the influence of too large height difference of individual air springs on the service life and driving comfort of the springs is avoided, and the height adjustment accuracy of the air suspension can be guaranteed.

Description

technical field [0001] The invention belongs to the technical field of automobiles, and in particular relates to a method and a device for adjusting the height of an air suspension. Background technique [0002] As a vehicle suspension configuration, the air suspension can change the height and softness of the vehicle by compressing the air and adjusting the air pressure, which can ensure the passability and comfort of the vehicle under different road conditions. In actual vehicle driving, due to differences in driving scenarios, the height of the air suspension is often adjusted adaptively in different driving modes. [0003] The existing air suspension adjustment method is mainly that the air suspension ECU controls the actuator to adjust the lift according to the feedback information of the vehicle speed or the air spring height, but this method ignores the error introduced by the simultaneous adjustment of the air spring, and the existence of the front and rear axles the...
