What is claimed is: 1. A door system for a vehicle having a vehicle body that encloses a passenger compartment, the door system comprising: a first vehicle door and a second vehicle door that are movable into a common vehicle door opening in the vehicle body, the vehicle doors being movable from an open position to a closed position in which vehicle doors are arranged lying opposite to each other in a connecting region; a plurality of stiffening elements for stiffening the vehicle doors in the vehicle door opening, wherein a first stiffening element is arranged in a connecting region of the first vehicle door and a second stiffening element is arranged in the connecting region of the second vehicle door, the stiffening elements being spaced apart when the vehicle doors are closed and in a rest position, in the event of an impact against the vehicle door in the closed position the stiffening elements move to an active position to interact in a force-transmitting manner to stiffen the vehicle doors in the connecting region, and further wherein the stiffening elements have cross-sectional profiles that are suitable for effective interengagement of the stiffening elements in the active position, wherein the cross-sectional profiles each have at least one hook comprising a limb and a transverse limb, which is arranged on a limb end side at an angle to the limb and has a plurality of limb side surfaces, the transverse limb of the first stiffening element is arranged to point essentially away from the passenger compartment and the transverse limb of the second stiffening element is arranged to point essentially toward the passenger compartment with the hooks being arranged to overlap in the closed position. 2. The vehicle door system as claimed in claim 1, wherein, in the active position, the stiffening elements bear against each other in a frictional and form-fitting manner perpendicular with respect to an outside of the vehicle doors in a transverse vehicle direction and counter to the closing direction. 3. The vehicle door system as claimed in claim 1, wherein the stiffening elements are arranged in a central section in the connecting region, with respect to the longitudinal extent of the connecting region, and such that they lie opposite each other in the rest position. 4. The vehicle door system as claimed in claim 3, wherein the central section comprises at least one region in which, in the event of a lateral impact, a temporally first deformation or a beginning of the deformation of the vehicle doors is to be anticipated. 5. The vehicle door system as claimed in claim 3, wherein, in the case of a vehicle door having an outward curvature from the passenger compartment, the central section comprises at least one region in which the outward curvature is at maximum. 6. The vehicle door system as claimed in claim 1, wherein the stiffening elements have an elongated shape and, in their longitudinal extent, are arranged in the connecting region. 7. The vehicle door system as claimed in claim 1, wherein the limb and transverse limb of the hooks are each formed at right angles to each other, and wherein the transverse limb is arranged approximately perpendicularly with respect to an outer surface of the vehicle door to which the transverse limb is attached. 8. The vehicle door system as claimed in claim 1, wherein the vehicle doors each have an outer panel and an inner panel that enclose a cavity and are connected to each other by a plurality of connecting flanges outside the cavity, and wherein the connecting flanges form the respective hook or at least the transverse limb of one of the vehicle doors. 9. The vehicle door system as claimed in claim 8, wherein the body panels are reinforced at least in the region of the stiffening elements. 10. The vehicle door system as claimed in claim 1, wherein a bar-shaped stiffening element is arranged in the connecting region of the first vehicle door and of the second vehicle door, and wherein the bar-shaped reinforcing element is manufactured from a polyamide, or from GFRP or CFRP. 11. The vehicle door system as claimed in claim 10, wherein the first stiffening element is reinforced by the bar-shaped stiffening element. 12. A door system for a vehicle having a vehicle body that encloses a passenger compartment, the door system comprising: a first vehicle door and a second vehicle door that are movable into a common vehicle door opening in the vehicle body, the vehicle doors being movable from an open position to a closed position in which vehicle doors are arranged lying opposite to each other in a connecting region; a plurality of stiffening elements for stiffening the vehicle doors in the vehicle door opening, wherein a first stiffening element is arranged in a connecting region of the first vehicle door and a second stiffening element is arranged in the connecting region of the second vehicle door, the stiffening elements being spaced apart when the vehicle doors are closed and in a rest position, in the event of an impact against the vehicle door in the closed position the stiffening elements move to an active position to interact in a force-transmitting manner to stiffen the vehicle doors in the connecting region; and wherein a third, bar-shaped stiffening element is arranged along the connecting end side of the first vehicle door and of the second vehicle door, and wherein the third reinforcing element is manufactured from a polyamide, or from GFRP or CFRP. 13. A door system for a vehicle having a vehicle body that encloses a passenger compartment, the door system comprising: a first vehicle door and a second vehicle door that are movable into a common vehicle door opening in the vehicle body, the vehicle doors being movable from an open position to a closed position in which vehicle doors are arranged lying opposite to each other in a connecting region; a plurality of stiffening elements for stiffening the vehicle doors in the vehicle door opening, wherein a first stiffening element is arranged in a connecting region of the first vehicle door and a second stiffening element is arranged in the connecting region of the second vehicle door, the stiffening elements being spaced apart when the vehicle doors are closed and in a rest position, in the event of an impact against the vehicle door in the closed position the stiffening elements move to an active position to interact in a force-transmitting manner to stiffen the vehicle doors in the connecting region, wherein at least one vehicle door is a sliding door which is movable by means of a guide rail on a nonlinear displacement path relative to the vehicle body. 14. The vehicle door system as claimed in claim 13, wherein the first stiffening element is arranged on the first sliding door.
