Abstract
An apparatus includes a center component defining a center chamber therein and first and second side components defining first and second chambers therein, respectively. The first and second side components are coupled to opposing ends of the center component with the first and second chambers in fluid communication with the center chamber. The center, first side and second side components are configured to extend substantially across a width of a vehicle. The apparatus further includes first, second and third pressure sensors in communication with the first, second and center chambers, respectively.
Claims18
A system, comprising a processor and a memory, the memory storing instructions executable by the processor to:
- receive signals from left, center, and right pressure sensors respectively coupled to left, center, and right chambers extending across a vehicle front end, each of the left, center, and right chambers pressurized prior to deformation at a greater pressure than a pressure outside the chambers;
- determine that a difference between at least one of the signals of the left and right pressure sensors and the signal from the center pressure sensor, following one of deformation of the left chamber or deformation of the right chamber, meets an oblique impact threshold;
- select operational parameters for at least one vehicle collision mitigation system based on the received signals;
- and
- apply the selected operational parameters.
