Abstract

The invention discloses a vehicle-mounted suspension positioning error detection method and device, a storage medium and electronic equipment. The method comprises the steps: obtaining a longitudinalangle maximum value alpha 1, a longitudinal angle minimum value alpha 2 and a longitudinal angle change rate alpha of a longitudinal thrust rod; calculating a longitudinal angle total change value alpha t in unit time according to alpha 1, alpha 2 and alpha; when the alpha t is greater than the maximum angle alpha 0 of the longitudinal angle change limit of the vehicle-mounted suspension, subtracting the alpha t and the alpha 0 to obtain the longitudinal angle error value of the vehicle-mounted suspension. By utilizing the method, the requirement on the accuracy can be reduced, the detection time is saved, the detection efficiency is improved, the positioning error of the vehicle-mounted suspension is detected in time, and the driving safety of the vehicle is improved.

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...
