Vehicle door opening assembly to control the opening of a vehicle door comprising an automated door latch mechanism, configured to release the vehicle door when actuated, comprising: • back-up actuation condition detection means, configured to detect a back-up actuation condition, • a back-up release module, comprising a handling element, mechanically linked to the automated door latch mechanism so as to enable release of the vehicle door in back-up actuation conditions, the handling element being configured to be able to adopt three positions: ∘ a hidden position, said position being adopted in absence of detected back-up actuation condition, ∘ a ready position, where it is accessible to the user to mechanically release the vehicle door, said position being adopted upon reception of a control command emitted by the back-up condition detection means, and ∘ a release position, adopted when a user interacts with the handling element in ready position, in which the back-up release module causes the automated door latch mechanism to mechanically release the vehicle door, characterized in that it further comprises guiding means, supporting the handling element and elastic means to move the guiding means and the handling element from the hidden position into the ready position, said guiding means comprising a slider carrying the handling element and a release mechanism sheath open on one end, the sheath containing the slider, the slider being configured to move in translation from a retracted position in which the slider and the handling element are contained in the release mechanism sheath to a deployed position in which the handling element is protruding out of the release mechanism sheath when the elastic means are released, the handling element is fixed to the slider so as to be rotatable with a rotation axis perpendicular to the slider motion between a retracted position in which it is coaxial with the slider and a position in which it is inclined so as to protrude laterally from the release mechanism sheath in direction of the user, and in that it further comprises secondary elastic means that cause the handling element to rotate in a visible position when the slider reaches the deployed position. • back-up actuation condition detection means, configured to detect a back-up actuation condition, • a back-up release module, comprising a handling element, mechanically linked to the automated door latch mechanism so as to enable release of the vehicle door in back-up actuation conditions, the handling element being configured to be able to adopt three positions: ∘ a hidden position, said position being adopted in absence of detected back-up actuation condition, ∘ a ready position, where it is accessible to the user to mechanically release the vehicle door, said position being adopted upon reception of a control command emitted by the back-up condition detection means, and ∘ a release position, adopted when a user interacts with the handling element in ready position, in which the back-up release module causes the automated door latch mechanism to mechanically release the vehicle door, characterized in that it further comprises guiding means, supporting the handling element and elastic means to move the guiding means and the handling element from the hidden position into the ready position, said guiding means comprising a slider carrying the handling element and a release mechanism sheath open on one end, the sheath containing the slider, the slider being configured to move in translation from a retracted position in which the slider and the handling element are contained in the release mechanism sheath to a deployed position in which the handling element is protruding out of the release mechanism sheath when the elastic means are released, the handling element is fixed to the slider so as to be rotatable with a rotation axis perpendicular to the slider motion between a retracted position in which it is coaxial with the slider and a position in which it is inclined so as to protrude laterally from the release mechanism sheath in direction of the user, and in that it further comprises secondary elastic means that cause the handling element to rotate in a visible position when the slider reaches the deployed position. ∘ a hidden position, said position being adopted in absence of detected back-up actuation condition, ∘ a ready position, where it is accessible to the user to mechanically release the vehicle door, said position being adopted upon reception of a control command emitted by the back-up condition detection means, and ∘ a release position, adopted when a user interacts with the handling element in ready position, in which the back-up release module causes the automated door latch mechanism to mechanically release the vehicle door,
