The invention provides a tire wear detection method, a tire wear detection device and a vehicle, and relates to the technical field of vehicle tire wear detection, and the tire wear detection method provided by the invention comprises the following steps: taking any point of the circumference of a tire as a test point, and detecting the x-axis acceleration of the test point; calculating a ratio ofthe grounding duration to the off-ground duration of the test point as a duration ratio; calculating the ratio of the square root of the average value of the x-axis acceleration squared values of thetest point in the grounding process to the square root of the average value of the x-axis acceleration squared values of the test point in the off-ground process as an amplitude ratio; performing a calibration test according to the duration ratio and the amplitude ratio to determine calibration parameters; and determining an abrasion value according to the duration ratio, the amplitude ratio andthe calibration parameter.
