ABSTRACT:
An intrusion detecting apparatus for a vehicle comprising an ultrasonic transmitting/receiving sensor, an intrusion detecting unit for detecting whether or not a person intrudes into a passenger compartment, based on the received signal, a stopping unit for intermittently stopping the transmission from the transmitter, and a cover detecting unit for detecting whether or not the sensor is covered, based on the signal received after stopping the transmission of the signal and, in response to a predetermined condition representing that the sensor is covered, whereby it can correctly determine whether or not the sensor is covered, improving the accuracy of the detection of an illegal intrusion of a person. At least one of a transmitter and a receiver in the sensor and the intrusion detecting unit is also intermittently operated to reduce the power consumption.
