| Claim | CLAIMS Automotive vehicle comprising: - a distal end, - at least one crash rail extending in a longitudinal direction of the vehicle towards the distal end, the crash rail comprising a free end, - a bumper system provided at the distal end, wherein the bumper system is configured to limit damage to the automotive vehicle in a low speed collision by absorbing a collision energy, wherein the bumper system comprises o a bumper beam extending substantially perpendicular to a longitudinal axis of the automotive vehicle, o at least one crash box extending substantially parallel to the longitudinal axis of the automotive vehicle, the at least one crash box comprising a first end and an opposite second end, wherein the first end is connected to the bumper beam, and wherein the second end is connected to the free end of the at least one crash rail of the automotive vehicle, wherein the bumper beam is configured to absorb at least 35%, preferably at least 40%, more preferably at least 45% of the collision energy in an RCAR low-speed structural crash test, and wherein the at least one crash box is configured to absorb at least 35%, preferably at least 40%, more preferably at least 45% of the collision energy in the RCAR low-speed structural crash test for limiting a maximum intrusion distance of the object. Automotive vehicle according to claim 1 , wherein the automotive vehicle comprises a chassis, wherein an outer body work is provided on the chassis, the outer body work comprising an upper surface comprising at least one solar pane Automotive vehicle according to claim 2, wherein in the low speed collision the maximum intrusion distance along the distal end defines a maximum intrusion line extending substantially parallel to the distal end at a distance thereof, wherein in top view the at least one solar panel extends from the maximum intrusion line away from the distal end. Automotive vehicle according to claim 2 or 3, wherein the at least one crash rail is connected at the free end thereof to the second end of the at least one crash box and at an opposite end thereof to the chassis, wherein in top view the at least one solar panel extends from the free end of the at least one crash rail away from the distal end. Automotive vehicle according to any one of the preceding claims, wherein the bumper system comprises two crash boxes which are located at a distance from each other in a direction substantially perpendicular to the longitudinal axis of the automotive vehicle. Automotive vehicle according to any one of the preceding claims, wherein the at least one crash box comprises a hollow beam, wherein an internal volume of the hollow beam comprises an aluminium foam fil Automotive vehicle according to the preceding claim, wherein the hollow beam has a wall thickness between 1 - 3 mm. Automotive vehicle according to any one of the preceding claims, wherein the bumper beam and/or the at least one crash box are made from a material comprising aluminium. Automotive vehicle according to any one of the preceding claims, wherein in cross- sectional view the bumper beam has a fill ratio of at least 25%. Automotive vehicle according to any one of the preceding claims, wherein the bumper beam has a wall thickness between 3 - 5 mm. Automotive vehicle according to any one of the preceding claims, wherein the bumper beam is curved in top view. Automotive vehicle according to any one of the preceding claims 5-11, wherein the bumper beam has a length, wherein the length is equal to or greater than a distance between two crash boxes and at least smaller than or equal to a distal width of the distal end of the automotive vehicle. Automotive vehicle according to any one of the preceding claims, wherein the bumper beam and the at least one crash box are configured to absorb the collision energy by plastic deformation thereof. Bumper system configured to be provided at a distal end of an automotive vehicle, wherein the bumper system is configured to limit damage to the automotive vehicle in a low speed collision with an object at the distal end by absorbing a collision energy, wherein the bumper system comprises o a bumper beam, o at least one crash box extending substantially perpendicular to the bumper beam, the at least one crash box comprising a first end and an opposite second end, wherein the first end is connected to the bumper beam, and wherein the second end is configured to be connected to a crash rail of the automotive vehicle, wherein the bumper beam is configured to absorb at least 35%, preferably at least 40%, more preferably at least 45% of the collision energy in an RCAR low-speed structural crash test, and wherein the at least one crash box is configured to absorb at least 35%, preferably at least 40%, more preferably at least 45% of the collision energy in the RCAR low-speed structural crash test for limiting a maximum intrusion distance of the object. |
