The invention discloses a vehicle safe driving early warning method and related equipment, and relates to the technical field of auxiliary driving, the method comprises the steps that vehicle driving information and driving road surface information are collected, and the vehicle driving information comprises the vehicle speed, the vehicle steering angle and the front and rear axle slip angle difference value; determining a vehicle performance boundary value corresponding to the driving road surface information through a whole vehicle simulation model; according to the vehicle speed, the vehicle steering angle and the front and rear axle slip angle difference value, a vehicle performance real-time value is obtained through calculation; determining a real-time offset rate according to the vehicle performance real-time value and the vehicle performance boundary value; and when the real-time deviation rate is greater than a first deviation rate threshold value, carrying out vehicle safe driving early warning. According to the method, the vehicle and road surface information is collected in real time, the simulation model is combined to evaluate the vehicle performance boundary, accurate early warning is achieved, and the driving safety and the driving experience are remarkably improved.
