Abstract: Methods and systems for detecting malfunctioning on-board telematics units in vehicles. A computing device may receive a first and second geofence location for a vehicle from a fleet management system. The computing device may determine whether it received a third location from an on-board telematics unit of the vehicle within a time period between receiving the first geofence location and receiving the second geofence location. The computing device may determine that the on-board telematics unit associated with the vehicle is in a state of anomaly in response to determining that the third location was not received from the on-board telematics unit of the vehicle within a time period between receiving the first geofence location and receiving the second geofence location.

Abstract: Methods and systems for identifying stock anomalies in a fleet management system. A computing device may be configured to receive a geofence location for a first vehicle from the fleet management system, and receive a second location from an on-board telematics unit of the first vehicle. The computing device may determine whether the received second location is within the received geofence location. The computing device may determining that the first vehicle is in a state of anomaly in response to determining that the received second location is not within the received geofence location.

Abstract: The present teachings relate to a method of maintaining a vehicle availability report with respect to a first location comprising determining the number of vehicles of a first type within a predetermined geofence at the first location determining the number of vehicles of the first type due to leave the first location within a predetermined time period determining whether the number of vehicles of the first type within the predetermined geofence is more than, equal to or less than the number of vehicles of the first type due to leave the first location within the predetermined time period and updating the vehicle availability report based on a result of each determining step.

Abstract: The present teachings relate to a method of creating a geofence for a first location comprising receiving a time that a first vehicle was at the first location from a fleet management system, receiving a time that the first vehicle was at a second location from an on-board telematics unit of the first vehicle, determining if the first vehicle was at the second location for a predetermined period of time before or after being at the first location, and creating the geofence for the first location as including the second location if it is determined that the first vehicle was at the second location for the predetermined period of time before or after being at the first location.
