The invention discloses a method and a device for vehicle steering speed early warning. The method comprises steps: the current wheel steering angle and the actual vehicle speed of the whole vehicle, and the first distance between the central point and the mass center of the whole vehicle are detected and acquired; according to the wheel base between the steering central point of the whole vehicle and the first axle, the tread of the whole vehicle, the first distance and the wheel steering angle, the current early warning safety speed of the whole vehicle is acquired; whether the actual vehicle speed is smaller than the early warning safety speed is judged; and if the actual vehicle speed is no smaller than the early warning safety speed, safety reminding information is generated for reminding a driver of the current vehicle steering overspeed. In the technical scheme of the invention, through acquiring the early warning safety vehicle speed in the case of steering of the vehicle and generating the safety reminding information when the actual vehicle speed is no smaller than the early warning safety speed to remind the driver, the driver thus reduces the vehicle steering speed, the technical problem that rollover is likely to happen in the case of steering of a high-capacity car in the prior art is solved, and the safety in the case of steering of the vehicle is improved.
