SYSTEM AND METHOD FOR A SENSOR MOUNTING SYSTEM
Provided herein a system and method for a bracket configured to position one or more sensors on a vehicle. A method for supporting a sensor on a vehicle includes: attaching an internal frame structure to an inside of a hood of a vehicle behind a grille supported by the hood; and attaching an external frame structure to the internal frame structure, where the external frame structure is positioned outside of the hood in front of the grille, where supports for the external frame structure extend through the grille and attach to the internal frame structure, where the external frame structure supports the one or more sensors at a position providing a line-of-sight not visible from inside a passenger compartment of the vehicle.
1 . A system for supporting one or more sensors on a vehicle comprising:
an internal frame structure secured behind a grille of the vehicle to an inside of a hood supporting the grille; and
an external frame structure positioned in front of the grille outside of the hood supporting the grille and secured to the internal frame structure through the grille,
wherein the external frame structure supports the one or more sensors at a position providing a line-of-sight not visible from inside a passenger compartment of the vehicle.
2 . The system according to claim 1 , wherein the internal frame structure is secured to the inside of the hood by at least one anchor point positioned above the grille and at least one anchor point positioned below the grille.
3 . The system according to claim 2 , wherein the at least one anchor point positioned above the grille comprises at least one upper bracket, wherein the at least one upper bracket is secured to the inside of the hood by an adhesive.
4 . The system according to claim 3 , wherein the at least one anchor point positioned below the grille comprises at least one lower bracket, wherein the at least one lower bracket is secured to the inside of the hood by an adhesive.
5 . The system according to claim 4 , wherein the internal frame structure is secured to the inside of the hood by at least two anchor points positioned on either side of the grille.
6 . The system according to claim 5 , wherein the internal frame structure provides greater rigidity to the hood of the vehicle.
7 . The system according to claim 1 , wherein the internal frame structure comprises at least one vertical member and at least one horizontal member, wherein the at least one vertical member and the at least one horizontal member are connected via a tab-and-slot connection.
8 . The system according to claim 7 , wherein the internal frame structure further comprises a weld bead between the at least one vertical member and the at least one horizontal member at the tab-and-slot connection.
9 . The system according to claim 1 , wherein the external frame support structure comprises a rail extending horizontally across a front of the hood, wherein the one or more sensors are repositionable along a length of the rail.
10 . The system according to claim 9 , wherein the one or more sensors comprise at least two LIDAR sensors and at least one camera.
11 . The system according to claim 10 , wherein the one or more sensors further comprise at least two radar units.
12 . The system according to claim 10 , wherein the at least two LIDAR sensors include a first LIDAR sensor positioned at a first end of the rail and a second LIDAR sensor positioned at a second end of the rail, opposite the first end.
13 . The system according to claim 12 , wherein the at least one camera is positioned proximate a middle of the rail.
14 . The system according to claim 12 , wherein the one or more sensors further comprise a center-mounted LIDAR positioned below the rail, wherein the center-mounted LIDAR defines a downwardly angled field-of-view.
15 . The system according to claim 14 , wherein the center-mounted LIDAR is a short-range LIDAR sensor.
16 . The system according to claim 15 , wherein the first LIDAR sensor and the second LIDAR sensor are long-range LIDAR sensors.
17 . A method for supporting one or more sensors on a vehicle comprising:
attaching an internal frame structure to an inside of a hood behind a grille supported by the hood; and
attaching an external frame structure to the internal frame structure, where the external frame structure is positioned outside of the hood in front of the grille, wherein supports for the external frame structure extend through the grille and attach to the internal frame structure,
wherein the external frame structure supports the one or more sensors at a position providing a line-of-sight not visible from inside a passenger compartment of the vehicle.
18 . The method according to claim 17 , further comprising:
securing the internal frame structure to the inside of the hood by at least one anchor point positioned above the grille and at least one anchor point positioned below the grille,
wherein the at least one anchor point positioned above the grille comprises at least one upper bracket, wherein the at least one upper bracket is secured to the inside of the hood by an adhesive.
19 . The method according to claim 17 , wherein the internal frame structure comprises at least one vertical member and at least one horizontal member, wherein the at least one vertical member and the at least one horizontal member are connected via a tab-and-slot connection that is welded together.
20 . The method according to claim 17 , wherein the external frame structure includes a rail extending horizontally across a front of the hood, wherein two or more LIDAR sensors and at least one camera are secured to the rail.
