The invention discloses a high-risk curve road section steering analysis reminding system based on an automatic positioning system, and relates to the technical field of vehicle running control. A main processing controller is arranged in a vehicle, and a storage unit is arranged in the main processing controller. A road section bending rate comprises a preset analyzed road section bending radiusand a turning chord tangent angle of each node of the road section; and an included angle between the connecting line direction between a second GPS module and a first GPS module and the tangent direction of the turning road section at the node position serves as the steering angle difference in the running process of the vehicle. Emergency braking deceleration time of the vehicle under the current vehicle speed state is analyzed, the safe deceleration distance of the vehicle under the current vehicle speed state is analyzed; the relationship between the forward boundary distance parameter ofthe vehicle and the safe deceleration distance under the current vehicle speed state is analyzed, and a steering angle adjustment alarm state is output. According to the system, the risk coefficient of vehicle meeting in a high-risk road section is reduced, and the safety of curve driving and emergency braking is also ensured.
