1. An apparatus for crash detection, the apparatus comprising:
- first, second, and third acceleration sensors installed at different positions of an object whose crash is to be detected; and
a crash detection unit configured to;
calculate expectation acceleration of the third acceleration sensor based on measurement information measured by the first acceleration sensor and the second acceleration sensor, anddetect whether a shape of the object has been deformed or not by comparing the expectation acceleration with a measured acceleration measured by the third acceleration sensor.

Abstract
A crash detection apparatus includes a crash detection unit and first, second, and third acceleration sensors which are installed at different positions of the object whose crash is to be detected. The crash detection unit calculates expectation acceleration of the third acceleration sensor based on measurement information obtained by the first acceleration sensor and the second acceleration sensor, compares the expectation acceleration with a measured acceleration measured by the third acceleration sensor, and detects whether a shape of the object has been deformed or not.
