1. A pre-crash side airbag device, comprising:

  • a side collision detection sensor configured to detect a collision occurring at a side of a vehicle;

    a pre-crash sensor disposed on the side of the vehicle, and configured to detect physical quantities related to a speed of an approaching object;

    a main airbag disposed between a vehicle occupant seat and the side of the vehicle, and deployed when a control signal is received;

    an auxiliary airbag coupled to one side of the main airbag so that the auxiliary airbag can be communicated with the main airbag; and

    a control unit configured to allow both the main airbag and the auxiliary airbag to be deployed even before a measurement value of the side collision detection sensor is received in a pre-crash case where a measurement value from the pre-crash sensor is received and a high-speed side collision is expected, and configured to allow the main airbag to be deployed after the measurement value of the side collision detection sensor is received in a normal case where the measurement value from the pre-crash sensor is received and a low-speed side collision is expected or the measurement value is erroneous.
