Additionally, changes in barometric pressure can be used in a similar manner as temperature. Due to the nature of HVAC systems, barometric pressure is often different inside of buildings and vehicles than it is in the open environment. Some modern mobile device have barometric pressure sensors capable of detecting these differences. Again, this reading could be correlated with third-party data for increased accuracy.
Software running on the mobile device can analyze sounds captured within the vehicle, such as distinct engine noises, that could be used to determine the mobile device receiving the signal is actually in a vehicle. The sounds could be compared independently of the system control device in the vehicle, or sound samples captured by both a control device in the vehicle as well as the mobile device itself could be compared. For example, algorithms can be used to determine that the sounds heard by a mobile device are consistent with sounds that would be heard while in a vehicle. More specifically, the captured sounds may be used to determine the type of vehicle in which the mobile device is located to further verify that the mobile device is located in the intended or expected vehicle. Furthermore, if a sample was taken by both the control device and by the mobile device, the sounds can be compared to see if they were taken from the same vehicle. To aid in comparison, the control device or mobile device may broadcast a high frequency tone to signify an identifiable sound that can be detected by the other device to confirm that both are within the same vehicle.
