Passenger protecting system
First Claim
1. A passenger protecting system comprising:
- at least two sensors which detect an impact to a vehicle due to a collision;
a determining unit for determining the collision with the vehicle based on detection signals of the sensors; and
a communication unit through which the sensors are connected with the determining unit so that the detection signals of the sensors are transmitted to the determining unit, whereinthe sensors detect the impact in a width direction of the vehicle and are prepared so that the detection signal of one of the sensors has a reverse polarity with respect to the detection signal of other of the sensors, and whereinwhen one of the sensors sends a positive detection signal and other of the sensors sends a negative detection signal, the determining unit determines there occurs the collision in the case where the detection signal of the one of the sensors is larger than or equal to a predetermined threshold value of the one of the sensors and the detection signal of the other of the sensors is smaller than or equal to a predetermined threshold value of the other of the sensors.

Abstract
A passenger protecting system is provided with at least two sensors which detect an impact to a vehicle, a determining unit for determining a collision with the vehicle based on detection signals of the sensors, and a communication unit through which the sensors are connected with the determining unit so that the detection signals of the sensors are transmitted to the determining unit. The detection signal of one of the sensors has a reverse polarity with respect to that of other of the sensors. Thus, the determining unit can be restricted from a faulty determination due to a fault of the communication path or the sensors, so that a misoperation of the passenger protecting system can be reduced.
