Abstract: An impact with a battery enclosure of a vehicle is classified based at least on processing impact sensor outputs to generate battery impact classification data. The impact sensor outputs are received from an impact sensor arrangement associated with the battery enclosure, the impact sensor arrangement being configured to generate the impact sensor outputs in response to a deformation of the battery enclosure. The vehicle is caused to perform an action in response to the battery impact classification data.

Abstract: An impact with an underside of a battery enclosure of a vehicle is classified based at least on processing impact sensor outputs to generate battery impact classification data. The impact sensor outputs are received from an impact sensor arrangement associated with the underside of the battery enclosure, the impact sensor arrangement being configured to generate the impact sensor outputs in response to a deformation of the underside of the battery enclosure. The vehicle is caused to perform an action in response to the battery impact classification data.

Abstract: An impact is detected with a vehicle having a body comprising parts which are deformable in an impact, by a secondary impact detection system configured to detect an impact that may not trigger a primary impact detection system. The secondary impact detection system comprises a plurality of deformation sensors attached to the deformable parts and configured to detect bending of the deformable parts. One or more processors are configured to receive a plurality of respective outputs from the plurality of deformation sensors, process the respective outputs to increase sensitivity to short-term changes relative to long-term changes and generate an indication of an impact dependent on detecting a processed output meeting a predetermined criterion. Outputs associated with a group of neighboring flex sensors may be used to localize the impact, characterize the source of impact, and/or reduce a likelihood of a false positive associated with the detection.

Abstract: There is provided a method and system for vehicle security protection. The method comprises: determining, at a detector, a first sensor signal from a flex sensor in an exterior panel of a vehicle, wherein the flex sensor and detector are powered by a power supply of the vehicle, and wherein a magnitude of the first sensor signal is based on an amount of bending of the flex sensor; determining, at the detector, based on the first sensor signal, that the exterior panel of the vehicle is deformed; and outputting, from the detector, a first alert signal, wherein a first controller of the vehicle is configured to transition from a low-power state to a high-power state based at least in part on the first sensor signal.
