Collision detection device, collision detection method, and collision detection program

A collision detection method for detecting a frontal collision of a vehicle, comprising:

• acquiring longitudinal acceleration output from a left-side sensor, which is an acceleration sensor installed on the left-side of a vehicle body and which detects the longitudinal acceleration and lateral acceleration and a right-side sensor, which is an acceleration sensor installed on the right-side of the vehicle body and detects the longitudinal acceleration and the lateral acceleration;
• acquiring the longitudinal acceleration output from a main sensor, which is an acceleration sensor different from the left-side sensor and the right-side sensor and which detects the longitudinal acceleration;
• and
• determining an occurrence of the frontal collision based on a safing determination based on the longitudinal acceleration acquired and a main determination based on the longitudinal acceleration acquired.
