Vehicle fuel electrical control method and system, vehicle and computer readable medium

The invention relates to a vehicle fuel oil electrical control method and system, a vehicle and a computer readable medium. The method comprises the steps acquiring the total vehicle speed variable quantity of the vehicle in a current collision process; judging whether the total variation quantity of the vehicle speed is out of a vehicle fuel oil electric control triggering threshold value line ornot; if so, triggering vehicle fuel electric cut-off control, the vehicle fuel oil electrical control triggering threshold line being an elliptic curve established according to a first change speed of the vehicle under the maximum non-triggering working condition of head-on collision, a second change speed of the vehicle under the maximum non-triggering working condition of side collision and a third change speed of the vehicle under the maximum non-triggering working condition of rear collision. The method does not depend on front, side and rear collision algorithms any more; and moreover, the coverage range of the threshold line is enlarged, the control stability is ensured to the maximum extent, the collision safety performance is improved, and complaints of after-sales accidents are reduced.
