摘要： Vehicle collision management systems and methods for use in a first vehicle are provided. The system includes an information collection unit, an information filter, and a collision calculation unit. The information collection unit receives driving data corresponding to a second vehicle, wherein the driving data includes a position of the second vehicle, and a driving course and a velocity of the second vehicle. The information filter filters the driving data of the second vehicle according to the driving data of the second vehicle and the first vehicle. The collision calculation unit performs a collision management for the first vehicle according to the filtered driving data of the second vehicle and the first vehicle.

摘要： A collision detecting method, an electronic device, and a computer program product thereof are provided for the electronic device having an accelerometer, a positioning module, and a communication module. The method includes obtaining a plurality of acceleration variations within each of a plurality of sampling intervals respectively detected by the accelerometer. The method also includes transforming the corresponding acceleration variations into a plurality of frequency domain signals for each sampling interval, and calculating energy and entropy of the frequency domain signals. The method further includes determining a collision has occurred if the energy and the entropy corresponding to each of a plurality of specific sampling intervals among the sampling intervals both drastically increase then drastically decrease suddenly.
