The invention discloses a vehicle self-adaptive speed limiting control method. The method comprises the following steps: reading an actual driving torque, a vehicle speed signal and a slope signal ofthe whole vehicle; using a whole vehicle dynamic model for calculation according to the signals, and calculating a whole vehicle resistance curve of the vehicle, wherein the calculation formula of theresistance curve is F = mg * atan (slope) + mg * atan (slope) * u + 0.5 * Aircd * VehCrossArea * v2 + m * a; carrying out optimal selection through the maximum acceleration under the current vehicleand the preset acceleration with the optimal drivability, and calculating a target acceleration curve; reading a target speed limit value, and selecting a target acceleration at the current vehicle speed from the target acceleration curve calculated in the step according to the target speed limit value; comparing the target acceleration with the current actual acceleration, and calculating the target acceleration for control; the target control torque is reversely recommended through the target acceleration for control, and the actual output torque is limited, so the control target value is converted into the control quantity. When the limit vehicle speed is controlled, a driver can be simulated to predict the state of the whole vehicle in advance, and a good driving effect is achieved.
