The invention discloses a vehicle door unlocking method and device, electronic equipment and a storage medium, and belongs to the field of vehicle control. The method comprises the steps that collision risk information between a vehicle and a target obstacle is actively detected, and under the condition that the collision risk information meets a target risk condition, an unlocking instruction is directly sent to a vehicle door of the vehicle. Different from a traditional mode, whether the safety air bag is exploded or not is not used as a unique signal source for unlocking the vehicle door, and the dilemma that the vehicle door cannot be unlocked due to the fact that the safety air bag is not exploded is avoided. By means of the innovative unlocking mechanism, no matter whether the safety air bag is triggered by collision or not, the automobile door can be unlocked in time as long as the collision risk exists. Therefore, precious time is won for escape of passengers in the automobile and rescue of rescue workers outside the automobile, safety of the passengers in the automobile in collision accidents is remarkably improved, and rescue risks and potential injuries caused by the fact that the automobile door cannot be unlocked in time are reduced.
