First Claim
Patent Images
1. An impact signal processor comprising:
- a first speed signal detection unit configured to detect a first speed signal of a vehicle using acceleration sensor data provided from an ACU (Airbag Control Unit) sensor;
a second speed signal detection unit configured to detect a second speed signal of the vehicle using acceleration sensor data provided from a FIS (Front Impact Sensor) sensor;
a phase lead unit configured to lead a phase of the first speed signal, and generating an upper threshold value and a lower threshold value that are changed to correspond to the first speed signal of which the phase has been led; and
a front impact speed estimation unit configured to estimate a front impact speed of the vehicle by processing the second speed signal using the upper threshold value and the lower threshold value.
