An electro-mechanical actuator for the release of a tailgate latch mechanism to open the tailgate by remote control in combination with a module that slows or stops the descent of the tailgate to prevent it from crashing down. In one embodiment the module is a pre-tensioned spring linkage with some degree of lost motion which arrests the tailgate in a partially open position. In another embodiment the module is a viscous fluid damper or a gas spring which limits the speed of travel of the tailgate. The actuator permits both manual and remote controlled opening of the tailgate is and suitable for after-market installation. Unintentional opening of the tailgate sends a warning to the operator.

What is claimed is: 1. An apparatus for assisting in the remote safe opening of a tailgate pivotally attached to a bed of a truck, comprising: an electro-mechanical actuator positioned inside the tailgate arranged to open tailgate latches; and a module that controls a descent of the tailgate upon opening of the tailgate latches, wherein the module includes a spring pre-tensioned in a closed position of the tailgate and a lost motion mechanism that arrests the tailgate in a partially opened position. 2. The apparatus of claim 1, wherein the electro-mechanical actuator provides for electro-mechanical opening of the tailgate latches or manual opening of the tailgate latches. 3. The apparatus of claim 1, wherein the pre-tensioned spring is a torsion rod. 4. The apparatus of claim 1, wherein the pre-tensioned spring is a spiral wound spring. 5. The apparatus of claim 1, further comprising an electrical switch which sends a warning signal indicating the tailgate is ajar. 6. An method for assisting in the remote and safe opening of a tailgate pivotally attached to a bed of a truck, comprising: opening tailgate latches with an electro-mechanical actuator positioned inside the tailgate; and upon opening of the tailgate latches, controlling a descent of the tailgate with a module by arresting the tailgate in a partially opened position, the module including a spring pre-tensioned in a closed position of the tailgate and a lost motion mechanism. 7. The method of claim 6, wherein opening tailgate latches with an electro-mechanical actuator provides for electro-mechanical opening of the tailgate latches or manual opening of the tailgate latches. 8. The method of claim 6, wherein the pre-tensioned spring is a torsion rod. 9. The method of claim 6, wherein the pre-tensioned spring is a spiral wound spring. 10. The method of claim 6, further comprising indicating the tailgate is ajar through a warning indicator. 11. An apparatus for remotely opening a tailgate of a truck, comprising: means for actuating tailgate latches to open the tailgate; and means for arresting the tailgate in a partially opened position, wherein the means for arresting includes a spring pre-tensioned in a closed position of the tailgate and a lost motion mechanism.
