Abstract

The application discloses a vehicle suspension positioning error detection method, device, storage medium and electronic equipment, which includes: obtaining the maximum longitudinal angle α1, the minimum longitudinal angle α2 and the longitudinal angle change rate α of the longitudinal thrust rod; according to α1 , α2, α Calculate the total change value of the longitudinal angle αt per unit time; when αt is greater than the maximum angle α0 of the longitudinal angle change limit of the vehicle suspension, make a difference between αt and α0 to obtain the longitudinal angle error value of the vehicle suspension. The application can reduce the requirement on accuracy, save the detection time, improve the detection efficiency, detect the positioning error of the vehicle suspension in time, and improve the driving safety of the vehicle.

Description

technical field [0001] The present application relates to the technical field of automobiles, in particular to a vehicle suspension positioning error detection method, device, storage medium and electronic equipment. Background technique [0002] Vehicle suspension is an important part to ensure ride comfort. The vehicle suspension is used as a force transmission device connected between the frame (or body) and the axle (or wheel), which can ease the impact load transmitted to the body from the uneven road surface, attenuate the vibration caused by it, and ensure the comfort of the passengers. . Therefore, the vehicle suspension plays an important role in the driving safety of the car. After the vehicle has been driven for a long time, the vehicle suspension will wear out. If the positioning detection and maintenance of the vehicle suspension are not carried out in time, serious safety hazards will occur. [0003] At present, most of the vehicle suspensions are tested by...
