US Patent 10543809 Systems and methods for identifying unauthorized vehicle use

Various arrangements for monitoring the unauthorized use of a vehicle are presented. An in-space parking sensor may be used to detect whether a vehicle is present. An indication of a time period during which the vehicle is expected to be within the parking space may be received. Using the sensor data obtained from the parking sensor, a vehicle departure from the parking space may be detected. A determination may be made that the vehicle departure is unauthorized due to the vehicle departure occurring during the time period. An alarm indication may be output based on determining that the vehicle departure is unauthorized.
