The invention relates to the technical field of new energy automobile cruise, and particularly discloses a vehicle cruise system based on acceleration self-adaption, which is used for solving the problems that a traditional cruise control system depends on speed control, cannot obtain the vehicle distance in time according to the relative acceleration of a front vehicle, cannot adjust power output in time when facing an uphill or downhill road section, and is inconvenient to use. The problems of unstable acceleration, low energy efficiency, poor driving experience, difficult acceleration caused by insufficient power during uphill, excessive acceleration during downhill, incapability of effectively utilizing regenerative braking and missing of opportunities of improving energy efficiency and reducing emission are solved. Comprising an acceleration sensing module, a power management module, an energy efficiency optimization module, a driver interaction module and a whole vehicle control unit. The acceleration and gradient data are monitored and analyzed in real time, the distance between the vehicle and the front vehicle is obtained in time, the safety of vehicle following cruise is guaranteed, power output is accurately adjusted, it is guaranteed that enough power is provided during uphill to overcome gravity, energy use is optimized during downhill, and energy waste is avoided.
