Abstract:
1. An occupant protection device for a vehicle comprising: a controller; first to fourth bus lines; a second row right side collision sensor arranged on a right side of the vehicle near a second row of seats, detecting an acceleration in a right-left direction of the vehicle, and transmitting a signal to the controller via the first bus line; a second row left side collision sensor arranged on a left side of the vehicle near the second row of seats, detecting an acceleration in the right-left direction of the vehicle, and transmitting a signal to the controller via the first bus line; a first row right side collision sensor arranged on the right side of the vehicle near a first row of seats, detecting an acceleration in the right-left direction of the vehicle, and transmitting a signal to the controller via the second bus line; a first row left side collision sensor arranged on the left side of the vehicle near the first row of seats, detecting an acceleration in the right-left direction of the vehicle, and transmitting a signal to the controller via the second bus line; a center collision sensor arranged on a center of the vehicle in the right-left direction, detecting an acceleration in the right-left direction of the vehicle, and transmitting a signal to the controller via the second bus line; a right front side collision sensor arranged on a right front side of the vehicle, detecting an acceleration in a front-rear direction of the vehicle, and transmitting a signal to the controller via the third bus line; and a left front side collision sensor arranged on a left front side of the vehicle, detecting an acceleration in the front-rear direction of the vehicle, and transmitting a signal to the controller via the fourth bus line, wherein the first to fourth bus lines are different from each other, wherein the controller determines a collision on at least one side of the vehicle based on the signals from the first and second row right side collision sensors, the first and second row left side collision sensors and the center collision sensor, wherein the controller, the first row left side collision sensor, the center collision sensor and the first row right side collision sensor are coupled in this order, and wherein the controller, the second row right side collision sensor and the second row left side collision sensor are coupled in this order.
