1. A collision detecting apparatus for a vehicle, the collision detecting apparatus comprising:
a bumper acceleration sensor provided at a front part of the vehicle, and configured to detect an acceleration rate to be applied to the vehicle by a collision of the vehicle;
a floor acceleration sensor provided on a floor member of the vehicle;
a pressure sensor extending in a vehicle width direction at the front part of the vehicle, and configured to detect a pressure to be applied to the vehicle by the collision of the vehicle; and
a processor and a memory communicably coupled to the processor, the memory storing instructions for causing the processor to execute the instructions including
making a determination on a state of the collision of the vehicle by comparing a detection value obtained from the pressure sensor with a preset first threshold, and by comparing a detection value obtained from the bumper acceleration sensor with a preset second threshold in a case where the detection value obtained from the pressure sensor is greater than the first threshold, and
controlling a threshold of the floor acceleration sensor on a basis of a result of the determination made on the state of the collision, and configured to change the threshold of the floor acceleration sensor from a preset third threshold to a preset fourth threshold that is less than the third threshold in a case where the processor determines that: the detection value obtained from the pressure sensor is greater than the first threshold; and the detection value obtained from the bumper acceleration sensor is equal to or less than the second threshold.
