The invention provides a driving behavior abnormity identification method and device, a vehicle and a storage medium, and belongs to the technical field of driving behavior detection.The method comprises the steps that starting process data and a plurality of preset gears of the vehicle are obtained; the starting process data comprises a plurality of gearbox output shaft rotating speeds and a plurality of engine rotating speeds which are in one-to-one correspondence with a plurality of starting time points; based on the multiple preset gears, the multiple gearbox output shaft rotating speeds and the multiple engine rotating speeds, a two-dimensional starting feature map is constructed; inputting the two-dimensional starting feature map into a starting gear recognition model to obtain a starting gear; and determining sliding friction work based on the starting gear, and determining whether the vehicle has an abnormal driving behavior or not based on the sliding friction work. According to the method, a shaft rotating speed sensor does not need to be additionally arranged, driving behavior abnormity recognition can be achieved only by obtaining the vehicle starting process data and the multiple preset gears, the driving behavior abnormity recognition cost is reduced, and the driving behavior abnormity recognition efficiency is improved.
