Abstract
A system for detecting leaks in vehicles comprises memory, a plurality of transducers, at least one sensor, an input device, and logic. The memory stores a plurality of transmit profiles. The transducers are disposed in a vehicle and configured to emit acoustic energy. The sensor is disposed outside of a vehicle and configured to sense the acoustic energy emitted by the transducers, and the input device is configured to receive a vehicle identifier identifying the vehicle. The logic is configured to select one of the transmit profiles for the transducers based on the vehicle identifier and to cause the transducers to emit the acoustic energy according to the selected transmit profile. The logic is further configured to detect at least one leak in the vehicle based on sample values indicative of the acoustic energy sensed by the at least one sensor and to provide an indication of the detected leak.
