The invention discloses an early warning method and device for safe driving of a vehicle in a bad environment, a medium and equipment. The method comprises the following steps: acquiring a real-time environment image and real-time driving data through vehicle-mounted equipment of a target vehicle; calling a pre-trained weather classification model to generate a current weather type of the target road; generating a current pavement friction coefficient and current visibility; according to the current pavement friction coefficient, the current visibility and the real-time driving data, generating an optimal safety speed limit; and generating a safe driving early warning scheme according to the optimal safe speed limit. According to the invention, the current road surface friction coefficient and the current visibility can be generated according to the real-time environment image of the target road, the optimal safe speed limit is calculated and generated according to the data and the real-time driving data of t
