Abstract:
1. An occupant protection device for a vehicle comprising: a controller; first and second bus lines; a first collision detection element arranged on a side of the vehicle, detecting a collision in a right-left direction of the vehicle, and transmitting a first detection signal to the controller via the first bus line; a second collision detection element arranged on a center of the vehicle in the right-left direction of the vehicle, detecting the collision in the right-left direction of the vehicle, and transmitting a second detection signal to the controller via the second bus line; and a third collision detection element arranged on a front side from the first collision detection element, detecting the collision, and transmitting a third detection signal to the controller via the second bus line, wherein the controller determines the collision on the side of the vehicle based on the first and second detection signals from the first and second collision detection elements, wherein the controller determines the collision on a part of the vehicle based on the third detection signal from the third collision detection element, wherein the part of the vehicle is disposed on the front side from the first collision detection element, wherein the controller controls to activate an occupant protection element corresponding to the collision, wherein the first bus line is different from the second bus line, wherein the third collision detection element is arranged on a first side of a first row of seats in the vehicle, wherein the first collision detection element is arranged on a first side of a row of seats different from the first row in the vehicle, and wherein the controller determines the collision on the side of the vehicle based on the third detection signal from the third collision detection element in addition to the first and second detection signals from the first and second collision detection elements.
