The invention discloses a gear shifting prompting device based on a self-correction gear shifting point. The gear shifting prompting device comprises a power module, a data acquisition module, a memorizer, a debugging and calibrating module, a single-chip microcomputer and a gear shifting prompting module. By means of the gear shifting prompting device, the optimal gear for current driving of a vehicle can be obtained by analyzing current power data of the vehicle, the required data come from an on-board diagnostics (OBD) system, no external sensor is needed, and the manufacturing cost is low. Meanwhile, the current gear shifting point can be corrected according to requirements, it can be ensured that the vehicle runs at the optimal gear, a driver is prompted to conduct gear shifting at the optimal gear shifting point, the running cost of the vehicle can be reduced, the fuel economy of the whole vehicle is improved, and due to the fact that the gear shifting reasonability is ensured, the service life of an engine and the whole vehicle can be prolonged.
