The invention relates to a driving pre-reminding method and device, and relates to the technical field of automotive electronics, and the method comprises the steps: collecting a to-be-recognized voice signal; performing framing processing on the to-be-recognized voice signal to obtain multiple pieces of framed feature information; based on a preset waveform similarity threshold, selecting pre-stored key features similar to the waveform of the feature information to obtain a to-be-tested feature set; according to a preset key feature category sequence and key features in the to-be-detected feature set, obtaining a sorting result, and according to the sorting result, generating control data; selecting pre-stored driving material information corresponding to the control data; and sending the driving material information to a vehicle-mounted display screen, so that the vehicle-mounted display screen displays characters or pictures corresponding to the driving material information. The method has the effect of improving the safety coefficient in the driving process.
