1. A collision detection device for a vehicle, comprising:

  • a collision detection sensor for the vehicle, which includes a single piezoelectric film which is flat, a plurality of pairs of electrodes which sandwich the piezoelectric film and measure voltages between the electrodes, and spaces provided between the plurality of pairs of electrodes; and

    a controller which detects collision of the vehicle based on detected results by the collision detection sensor for the vehicle;

    wherein the controller estimates collision forces at the spaces by calculating a line which smoothly connects measurements at the plurality of pairs of electrodes.
