The invention discloses a vehicle transmission and braking system working condition self-adaptive control method based on driving intention identification. The method comprises the following steps that vehicle driving data are collected through a vehicle-mounted sensor; the method comprises the following steps of: establishing a prediction model for predicting future acceleration and slip rate/slip rate by taking an automobile driving data acquisition result as a sample, accessing an automobile control system after offline training of the prediction model is completed, and performing online optimization on the prediction model by acquiring real-time driving data; the prediction results of the acceleration and the slip rate/slip rate in the prediction model after online optimization are used as input, the driving intention of the automobile is judged through the fuzzy theory, a theoretical basis is provided for automobile control, and a vehicle transmission and a braking system hydraulic device are controlled according to the driving intention identification result so that the control target can be achieved. According to the method, the identification precision can be improved, the real driving intention can be reflected more accurately, and the pre-judgment of the driving intention of the automobile during unmanned driving is realized.
