The invention relates to an active energy absorption longitudinal beam, a control method, a vehicle and a storage medium. The active energy absorption longitudinal beam comprises an anti-collision beam, an energy absorption box, an energy absorption box end plate, an energy absorption device, a longitudinal beam end plate, a longitudinal beam, a collision sensor, a relative speed sensor and a controller. The anti-collision beam is connected with the front end of the energy absorption box; the energy absorption box end plate is connected with the rear end of the energy absorption box; the longitudinal beam end plate is connected with the front end of the longitudinal beam; the energy absorption device is located in a cavity of the longitudinal beam and connected with the longitudinal beam. The energy absorption device is connected with the energy absorption box end plate; the controller compares the vehicle collision strength with a preset vehicle collision strength threshold value, and when the vehicle collision strength is larger than the preset vehicle collision strength threshold value, the energy absorption device is started, and the energy absorption box end plate, the anti-collision beam and the energy absorption box are pushed to horizontally move towards the front of the vehicle together; and the compression reaction force of the energy absorption device is adjusted according to the relative collision speed. On the premise that the size of the front cabin is small, the energy absorption effect in the collision process is improved.
