Multi-mode gear shifting and error-proofing self-adaptive adjusting method and system

The invention provides a multi-mode gear shifting and error-proofing self-adaptive adjusting method and system, and the method comprises the steps: S1, receiving current gear shifting mode information through a TCU, and determining a current vehicle operation gear shifting curve; s2, the TCU obtains, counts and records current vehicle operation information in real time, wherein the current vehicle operation information comprises engine rotating speed, vehicle speed, mass, gradient and driving subtotal mileage information; and S3, the TCU judges a reasonable gear shifting mode of the current vehicle according to the engine speed distribution proportion, the vehicle speed distribution proportion, the mass distribution proportion and the gradient distribution proportion in a driving subtotal mileage. According to the method, when a wrong mode is selected for misjudgment or misoperation of a driver, the gear shifting mode is automatically recognized and corrected according to real-time road spectrum driving infor
