Pre-Crash Side Air Bag Device
First Claim
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.

Abstract
A pre-crash side airbag device includes a side collision detection sensor, a pre-crash sensor, a main airbag, an auxiliary airbag, and a control unit. The side collision detection sensor detects a collision occurring at the side of a vehicle. The pre-crash sensor detects physical quantities related to the speed of an approaching object. The main airbag is deployed when a control signal is input. The auxiliary airbag is coupled to one side of the main airbag. The control unit controls the deployment of the main airbag and the auxiliary airbag depending on a pre-crash case where a high-speed side collision is expected and a normal case where a low-speed side collision is expected or the measurement value is erroneous.
