Abstract: A vehicle tracking unit preferably includes a vehicle position determining device, a wireless communications device, and a controller connected to the wireless communications device and the vehicle position determining device. The controller preferably cooperates with the wireless communications device to generate a sequence of alert message notifications for the user, and for canceling any remaining alert message notification of the sequence based upon a cancellation command response from the user having already received the alert message notification.

Abstract: A tracking unit for a vehicle may include a vehicle position determining device, a wireless communications device, and a controller cooperating with the wireless communications device and the vehicle position determining device to determine and send vehicle position information to a user. The controller may store a user selected reference location, and send the vehicle position information based upon the vehicle moving beyond a radial threshold distance from the user selected reference location. More particularly, the vehicle position information may be sent a threshold time after the vehicle moves beyond the radial threshold distance from the user selected reference location if the vehicle has not moved back within the radial threshold distance. Additionally, the vehicle tracking unit may further include at least one input device to be positioned within the vehicle for setting the user selected reference location.

Abstract: A pre-warn vehicle security device is for a vehicle including a data communications bus, an alert indicator, and an alarm controller interfacing with the data communications bus. The alarm controller may cause the alert indicator to generate an alarm indication responsive to a high security threat level. More particularly, the pre-warn vehicle security device may include a housing and a multi-stage sensor carried by the housing. The multi-stage sensor may sense the high security threat level and communicate the sensed high security threat level to the alarm controller via the data communications bus. It may also sense a low security threat level lower than the high security threat level. Moreover, the pre-warn vehicle security device may also include a pre-warn indicator carried by the housing and connected to the multi-stage sensor for generating a pre-warn indication responsive to the sensed low security threat level.

Abstract: A pre-warn vehicle security device is for a vehicle including a data communications bus, an alert indicator, and an alarm controller. The alarm controller may interface with the data communications bus and, when in an armed mode, may cause the alert indicator to generate an alarm indication responsive to a high security threat level. More particularly, the pre-warn vehicle security device may include a pre-warn vehicle security sensor for sensing a threat level lower than the high security threat level and a pre-warn emulator. Responsive to the pre-warn vehicle security sensor, the pre-warn emulator may generate at least one signal on the data communications bus so that the alarm controller causes the alert indicator to generate an emulated pre-warn indication different from the alarm indication.
