Abstract

A vehicle comprising: an audio system, local sensors including crash sensors, a fuel pump, and a processor configured to: (a) select a filter based on a determined audio system state; (b) pass the filter Purging the current crash sensor data; (c) determining whether to deactivate the fuel pump based on the purge data. The processor is configured to map the previous crash sensor data to the previously determined audio system state and to select a filter by selecting some of the mapped previous crash sensor data.

Description

technical field [0001] The present disclosure relates to sanitization of signals or data generated by vehicle sensors. Background technique [0002] The vehicle includes crash sensors that detect a collision or impact of the vehicle. Vehicles apply crash sensors to improve crash or crash results. For example, many vehicles cut off the fuel supply to the engine when a collision or impact is detected. Shutting off the fuel supply to the engine reduces fire hazards associated with collisions or impacts, thereby increasing vehicle safety. [0003] In addition to crash sensors, vehicles also include audio systems such as horns and audio speakers. Audio systems can be OEM (Original Equipment Manufacturer) (i.e. manufacturer installed) or aftermarket (i.e. installed at a shop not affiliated with the manufacturer). Audio systems can cause vibrations that deflect or contaminate the crash sensors. This bias or contamination can lead to false positive collision or impact detection...
