The invention discloses a driver takeover ability prediction method and device, a medium and a product, and relates to the field of automatic driving. Performing first preprocessing on the electroencephalogram signal to obtain a preprocessed electroencephalogram signal; performing second preprocessing on the eye movement information to obtain an eye movement hotspot map; performing feature extraction on the preprocessed electroencephalogram signals to obtain electroencephalogram signal features; determining the eye movement entropy of the to-be-predicted driver according to the eye movement hotspot map; according to the electroencephalogram signal features and the eye movement entropy, determining the takeover ability of the to-be-predicted driver by using a driver takeover ability prediction model; the driver takeover capability prediction model is obtained by training a decision tree model by using a training data set; the training data set comprises electroencephalogram signals and eye movement information of the driver for training and corresponding takeover ability labels. According to the method, the electroencephalogram signals and the eye movement information are combined, and the takeover ability of the driver is accurately predicted.
