Vehicle-compartment abnormality detection apparatus

A vehicle-compartment abnormality detection apparatus configured to be applied to a vehicle, the vehicle-compartment abnormality detection apparatus comprising:

• a sensor signal processor configured to receive a sensor signal from a group of pressure sensors disposed inside a vehicle compartment of the vehicle;
• a comparator configured to make a comparison of a sensor signal level that is a signal level of the sensor signal received by the sensor signal processor with a predetermined threshold;
• a determiner configured to
• start up when a result of the comparison made by the comparator indicates that the sensor signal level is greater than the predetermined threshold in a state where a drive system of the vehicle is stopped, and
• make a first determination at least as to whether a key is present inside the vehicle compartment;
• and
• an abnormality detector configured to
• start up when the result of the comparison made by the comparator indicates that the sensor signal level is greater than the predetermined threshold in the state where the drive system of the vehicle is stopped, and
• detect an abnormality occurring inside the vehicle compartment when a result of the first determination made by the determiner indicates that the key is not present inside the vehicle compartment.
