The invention discloses a creeping noise analysis method, a creeping noise test method and a creeping noise test device for a vehicle braking system. The creeping noise analysis method for the vehicle braking system comprises the following steps: acquiring creeping noise test data of a to-be-tested braking system mounted on a vehicle under various brake states, wherein the brake states comprise a normal-temperature brake state, a watering brake state and a watering overnight brake state; obtaining a weight coefficient of each brake state; and acquiring the creeping noise level of the brake system to be tested according to the creeping noise test data in each brake state and the weight coefficient. According to the creeping noise analysis method for the vehicle braking system, the influence of the braking working condition, the environment humidity and the braking system friction pair state on braking creeping noise can be comprehensively considered, so that the overall creeping noise level of the braking system is comprehensively analyzed, and compared with the prior art, the testing is more comprehensive, and the testing efficiency is improved. And the overall creeping noise level of the braking system is analyzed more reasonably.
