Abstract
A collision determination apparatus receives sensor data, which includes a sensor identifier, from multiple sensors that are of at least two different sensor types. Based on the sensor data from each of the sensors, a main determination unit determines whether to operate a protection apparatus. In parallel, a redundant determination unit determines whether to operate the protection apparatus based on at least one sensor data and by switching sub-determination units that have different determination logics according to a sensor type. In particular, the sensor identifier includes a sensor type information that allows the redundant determination unit to determine the sensor type of the sensor that transmitted the sensor data, and select the appropriate sub-determination unit. Therefore, based on the sensor type information in the sensor data, the same collision determination apparatus can be used in different vehicles that have respectively different number of sensors and different sensor types.
